Annaba
Opis:
Poor air quality can pose severe risks to human health and can also influence negatively on the natural environment. Annaba suffers from air pollution due to the industrial activities occurring in the province including, electricity generation, waste incineration, chemistry and other small additional industrial operations. However, mining, steel industry and metallurgy are considered among the most polluting activities. The aim of our research is to assess the risks of air pollution emissions with NO2, SO2, Toluene and Benzene as a result of industrial enterprises activities in Annaba province. The application of geo-graphical information system (GIS) mapping based on automatic monitoring networks of air quality, allows us the assessment of air pollution risks in the studied area. Two zones of air pollution with N02 in the level of 1 MPC has been recorded near the blast furnaces and the steel shop, the second halo of NO2 pollution was fixed over residential infrastructures. Moreover, revealed a tendency to higher content of nitrogen dioxide in the atmosphere of the bigger part of Annaba region. Corresponding to the data obtained from stationary monitoring networks, the annual average concentration of SO2 was significantly lower than the MPC. Based on GIS maps there are two areas with SO2 pollution inside the territory of El Hadjar metallurgical plant. A significant increase in concentrations of NO2 in the atmosphere of the industrial areas was recorded in the first decade. On average during three years the highest content of technogenic dust was detected in El Bouni.

Opis:
The heavy metal contamination has become a serious problem in the aquatic environment, including marine sediments. This study was aimed at analyzing the content of heavy metals in marine sediments, then assessing and evaluating the level of heavy metal contamination and its ecological risks. The sediment samples were taken using a grab sampler at six sites in the coastal waters of Mimika Regency, Indonesia. The TCLP testing method was used to determine the content of heavy metals in marine sediments. The results showed that the concentrations of Pb, Cu, Cd, and Hg in marine sediments ranged from <0.25 to 0.59 ppm, <0.02 to 0.54 ppm, <0.005 to 0.03 ppm, and < 0.0007 ppm. Only the concentrations of Cu on the Meoga and Puriri sites exceeded the quality standard in the Government Regulation of the Republic of Indonesia No. 18 year 1999. The results of the assessment of heavy metal contamination and its ecological risk potential indicate that the coastal waters of Mimika Regency are included in the category of low contamination and low ecological risks. The concentration of heavy metals in this study shows that the coastal waters of Mimika Regency are not contaminated by Pb, Cu, Cd, and Hg heavy metals.

Opis:
The Mio-plio-quaternary aquifer of the Djelfa Syncline is part of a region in Algeria which is characterized by the lack of surface water resources and located in a semi-arid climate. Since alluvial aquifers, and among them our aquifer, are the most vulnerable because of thier direct exposure to the pollution caused by the infiltrated pollutants, this work focused on the assessement of groundwater pollution vulnerability, hazard and risk. Thus, several methods were used; for this purpose, such as the DRASTIC and WQI methods mapped using a GIS. The results obtained clearly show a low to moderate vulnerability. The DRASTIC model and its validation based on the correlation with WQI revealed a low correlation ($WQ_I$vs $D_I$ : 0.221). Since the vulnerability model does not match with the groundwater quality, pollution risk was assessed by combining vulnerabilty and hazard (i.e, water quality). The risk map illustrated three levels ranging from low to high risk. This map should be helpful in decision making and groundwater management through avoiding high risk areas.

Opis:
The intrinsic vulnerability of groundwater aquifers refers to their sensitivity to all contamination coming from soil surface irrespective of the nature of the polluting. In order to improve the protection of groundwater, there must be a reduction in the infiltration of contaminants towards the reservoir through the impacting factors determination of this phenomenon by means of research. There are collected models that include particular number of factors which allow the determination of a sign of groundwater vulnerability of all superficial pollutions. The goal of the study centers on ascertaining the state of vulnerability and the risk of groundwater pollution of the Collo region with a new proposed method by Kherici. Generally, assessment methods of vulnerability and the danger of groundwater pollution employ parametric systems with numerical quotation, cartographic superposition where the analytical methods are based on equations. In this study, we consider the combination of criteria dependent on natural factors (thickness of the unsaturated zone, geologic facies, degree of auto-purification) and the causes of groundwater vulnerability to man-made pollution (anthropogenic factors).
Podatność podziemnych poziomów wodonośnych odnosi się do ich wrażliwości na zanieczyszczenia pochodzące z powierzchni gleby, niezależnie od ich charakteru. Dla ochrony wód gruntowych konieczne jest ograniczenie infiltracji zanieczyszczeń po ustaleniu czynników wpływu metodami badawczymi. Istnieją modele obejmujące szereg czynników, które umożliwiają określenie podatności wód gruntowych na zanieczyszczenia powierzchniowe. Celem badań było określenie stanu podatności i ryzyka zanieczyszczenia wód gruntowych w regionie Collo za pomocą nowej metody zaproponowanej przez Kherici. W metodach oceny podatności i zagrożenia zanieczyszczeniem wód gruntowych stosowane są zwykle parametryczny system numeryczny i kartograficzne nałożenia, w których metody analityczne bazują na równaniach. W pracy rozważano kombinację kryteriów zależnych od czynników naturalnych (miąższość strefy nienasyconej, facje geologiczne i stopień samooczyszczenia) oraz przyczyny podatności wód gruntowych na zanieczyszczenia antropogeniczne.

Opis:
Burning of fossil fuels and biomass, transport and industry are the main sources of PAH (Polycyclic Aromatic Hydrocarbons) in the atmosphere. Benzo[a]pyrene (BaP) is also a compound identified in cigarette smoke. The International Agency for Research on Cancer (IARC) has qualified benzo[a]pyrene for compounds with proven carcinogenic effects on humans. The target value for benzo[a]pyrene, taking into account health protection purposes, is defined in the Regulation of the Minister of the Environment on the levels of certain substances in the air and it is annual average concentration 1 ng/m3. The aim of the study was to carry out a cancer risk assessment for residents of Wroclaw, Krakow and Warszawa related to inhalation exposure to benzo[a]pyrene in ambient air. The methodology employed by the American Environmental Protection Agency (US EPA) was used in the study. The lifetime exposure of adults and children was assumed. The results of measurements carried out at the air monitoring stations under the State Environmental Monitoring by the Regional Inspectorates for Environmental Protection (RIEP) in Wroclaw, Krakow and Warszawa in the years 2014–2016 were used. The average concentration of BaP in the years 2014–2016 was 3.84, 6.31 and 2.19 ng/m3 for Wroclaw, Krakow and Warszawa respectively. The calculations show that the highest risk of cancer was obtained for the inhabitants of Krakow: 1.54 ∙ 10-5 children, 7.52 ∙ 10-6 women, 6.30 ∙ 10-6 men. The estimated cancer risk was higher for Krakow residents than for Wroclaw (1.01 ∙ 10-5 children, 4.94 ∙ 10-6 women, 3.82 ∙ 10-6 men) and Warszawa, where these indicators were the lowest (children: 5.34 ∙ 10-6, women: 2.61 ∙ 10-6, men: 2.19 ∙ 10-6). Children are the group most exposed to the risk of cancer associated with BaP in the air among the examined subpopulations.
Źródłami WWA (wielopierścieniowe węglowodory aromatyczne) do atmosfery są m.in. transport, przemysł oraz spalanie paliw kopalnych. Benzo[a]piren jest także związkiem identyfikowanym w dymie papierosowym. Międzynarodowa Agencja Badań nad Rakiem (IARC) zakwalifikowała benzo[a]piren do związków o udowodnionym działaniu rakotwórczym na człowieka. Dopuszczalne stężenie benzo[a]piren ze względu na ochronę zdrowia określono w Rozporządzeniu Ministra Środowiska w sprawie poziomów niektórych substancji w powietrzu i wynosi ono 1 ng/m3. Celem pracy było przeprowadzenie oceny ryzyka nowotworowego dla mieszkańców Wrocławia, Krakowa i Warszawy związanego z narażeniem inhalacyjnym na benzo[a]piren w powietrzu atmosferycznym. W pracy zastosowano metodykę Amerykańskiej Agencji Ochrony Środowiska (US EPA). W badaniach założono narażenie całożyciowe osoby dorosłej oraz dziecka. W pracy wykorzystano wyniki pomiarów przeprowadzanych w ramach Państwowego Monitoringu Środowiska przez Wojewódzkie Inspektoraty Ochrony Środowiska (WIOŚ) we Wrocławiu, Krakowie oraz w Warszawie w latach 2014–2016. Średnia wartość stężenia B[a]P w latach 2014–2016 wyniosła dla Wrocławia, Krakowa i Warszawy odpowiednio: 3,84, 6,31 i 2,19 ng/m3. Z przeprowadzonych obliczeń wynika, iż najwyższą wartość ryzyka nowotworowego otrzymano dla mieszkańców Krakowa: dzieci: 1,54 ∙ 10-5, kobiety: 7,52 ∙ 10-6, mężczyżni: 6,30 ∙ 10-6. Wyznaczone wartości ryzyka nowotworowego były wyższe dla mieszkańców Krakowa niż Wrocławia (dzieci: 1,01 ∙ 10-5, kobiety: 4,94 ∙ 10-6, mężczyżni: 3,82 ∙ 10-6) i Warszawy, gdzie wyznaczone wartości ryzyka były niższe (dzieci: 5,34 ∙ 10-6, kobiety: 2,61 ∙ 10-6, mężczyżni: 2,19 ∙ 10-6). Wśród badanych populacji najbardziej narażone na ryzyko nowotworowe związane z obecnością B[a]P w powietrzu są dzieci.

Opis:
The protection and preservation of good groundwater quality is of critical importance worldwide, nowadays. Increasing urbanization, economic development and agricultural activities, combined with limited precipitation contribute to the quantitative and qualitative degradation of groundwater resources, especially in the eastern Mediterranean region. For this purpose, a series of actions are implemented including groundwater vulnerability mapping that can depict prone to pollution aquifers which need protection and/or restoration measures. In this study, the efficiency of two well-known methodologies (COP and DRASTIC) for groundwater vulnerability and pollution risk mapping was assessed in the Sperchios river basin. The vulnerability and pollution risk maps of the two methodologies were spatially compared to each other and the observed similarities and differences were discussed and explained. The output of the study shows that in the particular geoenvironmental conditions DRASTIC method performs better than the COP, particularly in the lowland, porous media aquifer.

Introduction. Population increasingly draws attention to the issues concerning the environment degraded by the progress of civilization and the impact of this process on health. However, public awareness of the risk exposure to indoor contaminants is lagging a long way behind knowledge regarding outdoor environmental hazards. The aim of the study was to assess the risk perception related to exposure to indoor environmental factors in the population of Silesia. Materials and methods. In this study the electronic version of a questionnaire survey – downloaded on the website www.moja-ankiety.pl. was used. During the 3-months duration of the project 552 subjects participated in the survey. In the study participated the Silesian Voivodeship inhabitants such as chat rooms users, newsgroups and online forum participants. Data analysis was performed by using statistical program – STATA Version 8 SE [9], where the Kruskall-Wallis test and χ 2 test were applied. Statistical significance was assessed at p value *0.05. Results. Despite the low perception of environmental health hazards inside the dwellings, the majority of respondents were able to indentify health effects and ways to reduce exposure to indoor air pollution. Both gender, place of residence, education level and age significantly affected the level of perception of respondents on the risk connected with exposure to indoor air pollution. Conclusion. It is necessary to continuously work on raising public awareness of environmental health hazards in confined spaces, the causes of their occurrence, types, effects and above all the ways to counter these threats.
Wstęp. Populacja mieszkańców zwraca coraz większą uwagę na kwestie związane z degradacją środowiska w wyniku postępu cywilizacyjnego i skutku tego procesu na zdrowie. Jakkolwiek ich świadomość narażenia na zanieczyszczenia wnętrz jest znacznie mniej zaawansowana w stosunku do zagrożeń środowiskowych z zewnątrz. Celem tego badania była ocena ryzyka związanego z narażeniem na czynniki środowiskowe wnętrz u mieszkańców województwa śląskiego. Materiały i metody. W tym badaniu zastosowano ankietę w wersji elektronicznej umieszczonej na stronie internetowej www.moja-ankiety.pl. W czasie trzymiesięcznych badań udział wzięło 552 uczestników, mieszkańców województwa śląskiego takich jak: użytkownicy czatów, grup dyskusyjnych i forów internetowych. Analiza danych była przeprowadzona przy użyciu programu statystycznego STATA Version 8 SE [9], gdzie zastosowano testy Kruskall-Wallis i χ 2. Istotność statystyczna była oceniona na poziomie wartości p*0,05. Wyniki. Pomimo niskiej percepcji odnośnie zdrowotnych zagrożeń środowiskowych wewnątrz pomieszczeń, większość respondentów była w stanie ocenić skutki zdrowotne i sposoby ograniczenia narażenia na zanieczyszczenia powietrza wnętrz. Zarówno płeć, miejsce zamieszkania, poziom wykształcenia jak i wiek wywierały znaczny wpływ na poziom percepcji respondentów co do ryzyka związanego z narażeniem na zanieczyszczenie powietrza wewnątrz. Wnioski. Koniecznym jest stałe podnoszenie społecznej świadomości dotyczącej środowiskowych zagrożeń zdrowia w pomieszczeniach zamkniętych, przyczyn ich powstawania, rodzajów, skutków i przede wszystkim sposobów zwalczania tych zagrożeń.

Opis:
The aim of the study was to investigate the content of trace elements in deposited particulate matter and to estimate the health risk to Kraków inhabitants, caused by the exposure to heavy metals in particulate matter deposition. The qualitative and quantitative assessments of selected heavy metals in deposited particulate matter have been carried out in the city of Kraków (Małopolska, southern Poland, 5 measuring points) for seven months, between February and September 2017. A comparative study was conducted at the same time in Małopolska (5 measuring points). The deposited particulate matter was collected gravitationally, using measurement plates covered with aluminum foil and paraffin jelly. The largest deposition of particulate matter was found in May and June. The highest amount of deposited particulate matter and metals present in it was determined in Kraków. The Hazard Quotient (HQ) evaluation for non-carcinogenic effect showed low risk for each metal. In the case of lead in particulate matter, the carcinogenic risk value did not reach 10−6 hence this risk is acceptable. The total carcinogenic risk for all routes of exposure to cadmium was higher, indicating the risk of cancer in children and adults, with children more exposed. However, the carcinogenic risk for cadmium was also acceptable. The study showed that the problem of poor air quality concerns not only the city of Kraków, but also the entire Małopolska region. Elevated metal concentrations in particulate matter indicate the need for monitoring it in the air.

Opis:
Nieświadomi konsekwencji przebywania w pomieszczeniach zamkniętych, uważamy je za w pełni bezpieczne, gdyż chronią nas one przed negatywnymi skutkami środowiska takimi, jak zmienność klimatu (temperatura, opady, wiatr). Pracujemy i przebywamy w pomieszczeniach zamkniętych, pokojach, szkołach, przedszkolach, uczelniach i innych miejscach spędzając w nich około 80-90% naszego życia codziennego. Mimo to raczej nie zdajemy sobie sprawy z nagromadzenia szkodliwych substancji organicznych i nieorganicznych zawartych w materiałach budowlanych i wykończeniowych oraz instalacjach. Narażenie na te substancje często powoduje choroby dróg oddechowych, czy skóry, a nawet choroby nowotworowe. Równie niebezpieczne są organizmy żywe; mikroorganizmy, roztocza i grzyby, odchody niektórych owadów, związki chemiczne (organiczne i nieorganiczne), cząsteczki kurzu oraz mikroaerozole. Można znacznie obniżyć ryzyko narażenia na te czynniki poprzez włączenie do współpracy firm odpowiedzialnych za prace budowlane, instalatorskie oraz wykończeniowe, jak również poprzez szeroko rozumiane utrzymywanie czystości w pomieszczeniach zamkniętych. Rozwiązanie problemu ryzyka w pomieszczeniach zamkniętych będzie znacznie łatwiejsze przy odpowiedniej edukacji społeczeństwa w tym zakresie.
Unaware of the consequences of dwelling in the interiors we consider them the safest place as they protect us from negative factors of external environment including the variability of climate (temperature, precipitations and wind). Time spent in the interiors, rooms, kindergartens, schools, universities and other places that we work in amounts to 80-90 % of our everyday life. Despite that fact we are usually unaware of the accumulation of toxicorganic and inorganic substances contained in construction, finishing and installation materials and stocks. Exposure to the mentioned factors is a frequent cause of respiratory tract and skin diseasesand even the cancer. Equally dangerous are living organisms, microbes, actinomycetes and fungi, excrements of some insect speciesas well as chemical compounds (organic and inorganic), particles of dust and microaerosoles. The threats could be reduced at a more intensive cooperation of construction, installatory and finishing in stitutions as well as a proper exploitation and keeping of cleanness in the interiors. Solving the risk issue would be much easier if the public were more educated in the ecology of interiors.

Opis:
Liquid chromatography-mass spectrometry was used to detect and analyze phenolic compounds in the surface waters of four urban lakes in Xi’an – Hancheng Lake, Xingqing Lake, Nanhu Lake, and Taohuatan Lake. A total of 5 phenolic compounds were detected from the water samples, with a concentration range of ND-100.32 ng/L, of which bisphenol A (BPA) and nonyl phenol (NP) were the main types of phenolic compounds pollution in the four lakes. Pearson correlation analysis was used to analyze the concentration of phenolic compounds in the lake waters of Xi’an City and the water quality indicators COD, TP, NH3 -N, DO, and pH during the same period. It was found that there was a significant positive relationship between the concentration of BPA and COD, the concentration of estradiol (17-beta-E2), estrone (E1) and TP and TN, the concentration of octylphenol (4-t-OP) and pH. The ecological risk assessment (ERA) shows that the concentration of BPA, 4-t-OP and NP in the lakes is at a medium risk level( is between 0.1–1), and that of E1 is at a high risk level (is greater than 1). Female cells (breast cancer cells) and male germ cells (testis cells) of mice were used as research objects to explore BPA and NP Toxic effect on mouse germ cells. BPA and NP at a concentration of 10-8 mol/L were found to have the most value-inducing effect on MCF-7 breast cancer cells positive for estrogen receptor. Obviously, both BPA and NP can induce the proliferation of testicular Sertoli cells.

Opis:
A total of 316 soil samples in the An Giang province were collected from the industrial zone (48 samples), mining (40 samples), farming (112 samples), landfills (88 samples) and cemeteries (28 a samples) to analyze toxic elements, including Cu, Zn, Pb, Cd and As. The geoaccumulation index (Igeo), pollutant load index (PLI) and potential ecological risk index (RI) were used to assess pollution levels and ecological risks. The results showed that the concentrations of heavy metals were almost still within the allowable limits of national standards. Cd was not detected. Heavy metals were detected in the soil in the following order: As < Pb < Cu < Zn, mining < industrial < landfill < cultivation < cemetery areas. The heavy metals contributing to soil environmental variability were similarly identified in the cemetery with industry and landfill with farming. The value of Igeo shows that As has a high potential to accumulate in soil in all land uses. The ranges of PLI values presented that the soil in industrial, farming, mining and landfills areas were classified moderate, while the cemetery areas has been rated at a high level. The RI values identified very high, high, and moderate ecological risks for cemetery, industrial and farming land and landfill, mining, respectively. The combination of PLI and RI indices showed that the cemetery areas were at the highest levels of pollution and risk. The results of this study provide scientific information on pollution level and ecological risks in various land use types supporting environmental zoning and managing strategies in the An Giang province.

Opis:
Coastal areas in Anantigha are utilized as dumpsite for industrial and domestic wastes including effluent from local industries and inhabitants of the area despite their usage for crop cultivation. Thus, the present study was designed to assess the concentration, pollution load and ecological risk of heavy metal in Anantigha coastal area. Standard pollution indices such as contamination factor (Cf), degree of contamination, pollution load index (PLI), enrichment factor (EF), geo-accumulation index (Igeo) and ecological risk index were deployed to assess the level of heavy metals contamination in the area. The results showed that the sediment was acidic under dried conditions and low in conductivity. The mean concentration levels of all the heavy metals were lower than their mean background values except for Al. The orders of dominance for concentration of heavy metals were: Al>Fe>Mn>Cu>Zn (Station 1) and Al>Fe>Mn>Zn>Cu (Stations 2, 3 and 4). Analyzed data showed that the sediments in the area are contaminated with Al with Igeo result showing station 2 and 4 been moderately to heavily contaminated with Al while station 4 was heavily contaminated with aluminium. Station 1 had low degree of contamination, whereas station 2 and 4 had moderate degree of contamination, and station 3 showed considerable degree of contamination. The PLI result indicates unpolluted condition and the area were not enriched by the studied heavy metals as shown by EF values. Hence, the sediment in Anantigha coastal marine area was classified as having low ecological risk factor. However, the levels of these metals are not static; there is tendency for increase as a result of increased human input and activities. Hence, there is a need for regular soil testing.

Opis:
Risks in the maritime domain have various sources, of which the transportation of oil and other noxious products is one of key concern to industry and public stakeholders. Operational or accidental releases of oil or other pollutants from ships or offshore facilities into the marine environment can have disastrous effects on the marine ecosystems, while also leading to very significant economical losses. Therefore, national states have implemented various mechanisms for preventing and responding to pollution in the maritime domain, with activities which are often embedded in regional cooperation frameworks clustered around certain sea areas. To support collaborative, harmonized, and risk-informed oil spill Pollution Preparedness and Response (PPR) planning for response authorities, the Baltic Marine Environment Protection Commission (HELCOM), together with its research partners, and with extensive end-user and stakeholder inputs, have developed the OpenRisk Toolbox. This toolbox includes several risk assessment tools and techniques, which can assist in providing answers to a range of PPR risk management questions in a range of organizational contexts. To better understand and ensure the applicability and usefulness of the OpenRisk Toolbox, a workshop was organized where some of these tools were tested. Selected end user and stakeholder views on the perceived usefulness of the tools were collected and analyzed. Another workshop focused on further development needs to implement the tools in organizational practices. This paper first presents the OpenRisk Toolbox, then describes the settings of the workshops. Finally, a summary of the end-user and stakeholder views on the tested tools, and on future development needs, is given.

Opis:
The year 2022 was marked by economic risks with potentially very sensitive impacts for countries in the Black Sea region. Given the limited capacity of Ukrainian ports, as well as the sanctions imposed on Russia, due to ongoing conflict, it was necessary to identify new destinations capable of taking over the flow of goods that normally went to the countries involved in this conflict. In addition to the risks specific to maritime transport, the risk of armed conflict comes with new challenges that can also materialize in the form of environmental impact. To analyze this potential impact, the study is being focused mainly on the analysis of the pollution risk generated by the emissions caused by the vessels calling the container terminal CSCT, located in Constanța harbor, and the emissions generated by the vehicles moving in the terminal. As estimated from the start all levels of pollution have increased, with the level of CO2 increasing from 11072.7 tons in 2021 to 11915.7 tons in 2022. The NOx emissions have a similar trend, as well as the other emission level measured and calculated.
