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:: The paper addresses the sensitivity of a novel method for quantifying the environmental risks associated with the current-driven transport of adverse impacts released from offshore sources (e.g. ship traffic) with respect to the spatial resolution of the underlying hydrodynamic model. The risk is evaluated as the probability of particles released in different sea areas hitting the coast and in terms of the time after which the hit occurs (particle age) on the basis of a statistical analysis of large sets of 10-day long Lagrangian trajectories calculated for 1987–1991 for the Gulf of Finland, the Baltic Sea. The relevant 2D maps are calculated using the OAAS model with spatial resolutions of 2, 1 and 0.5 nautical miles (nm) and with identical initial, boundary and forcing conditions from the Rossby Centre 3D hydrodynamic model (RCO, Swedish Meteorological and Hydrological Institute). The spatially averaged values of the probability and particle age display hardly any dependence on the resolution. They both reach almost identical stationary levels (0.67–0.69 and ca 5.3 days respectively) after a few years of simulations. Also, the spatial distributions of the relevant fields are qualitatively similar for all resolutions. In contrast, the optimum locations for fairways depend substantially on the resolution, whereas the results for the 2 nm model differ considerably from those obtained using finer-resolutionmodels. It is concluded that eddy-permitting models with a grid step exceeding half the local baroclinic Rossby radius are suitable for a quick check of whether or not any potential gain from this method is feasible, whereas higher-resolution simulations with eddy-resolving models are necessary for detailed planning. The asymptotic values of the average probability and particle age are suggested as an indicator of the potential gain from the method in question and also as a new measure of the vulnerability of the nearshore of water bodies to offshore traffic accidents.

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:: W artykule przedstawiono wpływ warunków meteorologicznych i szorstkości aerodynamicznej podłoża na rozprzestrzenianie się substancji niebezpiecznej, wysoce toksycznej – chloru. Przeprowadzono symulacje w programie ALOHA, zakładając, że w wyniku nagłego zdarzenia następuje wyciek 10 ton płynnego chloru z przewożącej go cysterny. Przyjęto, że czas wycieku wynosił jedną godzinę. Otrzymane wyniki naniesiono na mapę z uwzględnieniem zakładanej lokalizacji: droga E463 w Pszczynie. Dokonano analizy stopnia zagrożenia w zależności od kierunku i prędkości wiatru. Dodatkowe symulacje wykonano przyjmując różne szorstkości aerodynamiczne. Analiza wyników pozwala określić najmniej korzystne warunki meteorologiczne z punktu widzenia bezpieczeństwa mieszkańców.
In the article was presented the effect of meteorological conditions and aerodynamic roughness of the substrate on the dispersion of dangerous, highly toxic substance - chlorine. Simulations were carried out in the ALOHA program, assuming that as a result of an emergency, 10 tons of liquid chlorine from the tanker carrying it were leaked. It was assumed that the leakage time was one hour. The obtained results were placed on the map taking into account the assumed location: road E463 in Pszczyna. The degree of hazard are analyzed depending on the direction and speed of the wind. Additional simulations were performed taking other leakage points and other aerodynamic roughness. The analysis of the results allows to determine the least favorable meteorological conditions from the point of view of the residents' safety.

Opis:: Środowisko naturalne stale zanieczyszczane jest przez różne substancje. Jednym z typów zanieczyszczeń środowiska naturalnego są farmaceutyki oraz ich metabolity. Ich obecność wykrywana jest w środowisku wodnym oraz glebowym. Ponadto zanieczyszczenie środowiska naturalnego przez farmaceutyki stale się zwiększa, co jest wynikiem rozwijającego się przemysłu farmaceutycznego, a także większego wykorzystania leków w gospodarstwach domowych. Nie bez znaczenia jest także nadużywanie farmaceutyków w rolnictwie, gdzie służą do zwiększenia jakości plonów lub do stymulowania wzrostu zwierząt gospodarczych. Ten nasilający się problem niesie za sobą wiele zagrożeń, zarówno dla ekosystemów, jak i dla zdrowia ludzkiego, bowiem farmaceutyki mogą wtórnie kumulować się w roślinnych i zwierzęcych tkankach, które stanowią źródło pożywienia dla człowieka. Ponadto, obecność tych substancji w środowisku powoduje narastanie zjawiska antybiotykooporności wśród mikroorganizmów w nim bytujących. Aby zapobiegać tym negatywnym skutkom zanieczyszczenia środowiska przez leki, należy przede wszystkim zminimalizować ich przedostawanie się do naturalnych ekosystemów. Działania w tym zakresie powinny być wielokierunkowe i obejmować sprawniejsze usuwanie farmaceutyków w procesie oczyszczania ścieków, zmniejszenie ilości farmaceutyków wykorzystywanych w rolnictwie, a także edukację społeczeństwa.
The natural environment is constantly polluted by various substances. One of the types of environmental pollution are pharmaceuticals and their metabolites. Their presence is detected in the water and soil environment. Moreover, pollution of the environment by pharmaceuticals is constantly increasing as a result of the growing pharmaceutical industry as well as the increased use of drugs in households. Another important factor is the abuse of pharmaceuticals in agriculture, where they are used to increase the quality of crops or to stimulate the growth of livestock. This growing problem carries many threats, both for ecosystems and for human health, because pharmaceuticals can accumulate in plant and animal tissues, which are a source of human food. Moreover, the presence of these substances in the environment increases the phenomenon of antibiotic resistance among the microorganisms living in it. In order to prevent these negative effects of environmental pollution from drugs, it is essential to minimize their leakage into natural ecosystems. Activities in this area should be multidirectional and include more efficient removal of pharmaceuticals in the wastewater treatment process, reduction of the amount of pharmaceuticals used in agriculture, and education of the society.

Opis:: Surface sediment quality of potential rivers in Peru was evaluated using indicators of contamination, accumulation and ecological risk of heavy metals and As. Surface sediment samples were collected at 54 sampling sites in the Tishgo and Chia rivers during 2018. The determination of Cu, Pb, Zn and As was performed by flame atomic absorption spectrophotometry. The results revealed the decreasing order of the mean concentrations of heavy metals and As in the Chia River of Zn > Cu > As > Pb and Tishgo of Zn > Pb > As > Cu. The PLI for the Tishgo River were greater than one (PLI > 1) denoting the deterioration it has been experiencing. In the Chia River, 60% of the sampling sites indicated no appreciable contamination by these elements (PLI < 1). The Igeo values of As in both rivers showed a state of contamination, from moderately to severely contaminated. In the Tishgo River the potential ecological risk varied from low to moderate and in the Chia River from low to considerable. Finally, this study reveals the applicability of the evaluation indexes of contamination, accumulation and potential ecological risk of toxic metals so that special control measures can be adopted.

Opis:: Objectives: There are few studies about the association between breathing polluted air and increased risk of cardiovascular diseases and cardiac death in the Middle East. This study aimed to investigate the relation between air pollutants and cardiovascular mortality (based on ICD-10) in Ahvaz. Material and methods: In this ecological study, the data about cardiovascular disease mortality and air pollutants from March 2008 until March 2015 was inquired from the Ahvaz City Authority and the Khuzestan Province Environmental Protection Agency. The quasi-Poisson, second degree polynomial constrained, distributed lag model; using single and cumulative lag structures, adjusted by trend, seasonality, temperature, relative humidity, weekdays and holidays was used for the data analysis purposes. Results: Findings indicated a direct significant relation between an interquartile range (IQR) increase in ozone and cardiovascular deaths among men after 3 days’ lag. There was also a significant relation between an IQR increase in particulate matter below 10 μm and cardiovascular deaths for all people, over 60 years old and under 18 years old after 3 and 13 days’ lags. There was a significant relation between an IQR increase in nitrogen dioxide and carbon monoxide, and cardiovascular deaths in the case of under 18-year-olds (in the lag 11) and over 60-year-olds (in the lag 9), respectively. We finally found a significant association between an IQR increase in sulfur dioxide and cardiovascular deaths in the case of men, under 18-year-olds and from 18- to 60-year-olds in the lag 9, 0, and 11, respectively (p-values < 0.05). Conclusions: It appears that air pollution is significantly associated with cardiovascular deaths in Ahvaz City. Int J Occup Med Environ Health 2018;31(4):459–473

Opis:: Purpose: Water is vital for the sustenance of every life form. Urbanization, growing population and industrial development has led to exploitation of water resources globally. This study assesses quality of water resources of Mohammedia prefecture. Design/methodology/approach: The water quality analysis was carried out based on physio-chemical and heavy metal concentrations. The physio-chemical analysis comprised of status of concentration, overall quality and water pollution index evaluation. The heavy metal evaluation consisted of Ecological Risk Index, non-carcinogenic risk and carcinogenic risk assessment. Findings: The landfill near Ben Nfifikh River reported insignificant (WPI<1) – low level of pollution (>1≤1.5) for surface and groundwater points. However, the groundwater for Zenata region was found to pose both carcinogenic (CRt > 0.0001, range 0.4-35.31) and non-carcinogenic risks (HQ>1, range 6 -34) of higher degree rendering it unfit for human consumption. Hence, this study concludes that groundwater resources should not as water supply; instead, Oud El Maleh River can serve as surface water source for meeting requirements of Zenata region. Research limitations/implications: The data obtained can be categorized as landfill area near river Nfifikh and landfill area near river El Maleh. Both areas have been investigated for groundwater and surface water quality assessment. Practical implications: This study demonstrates the need to study the characteristics of groundwater (depth, flow rate, water renewal, etc.) before arranging a waste dump. This problem is especially relevant for arid countries, since residents experience a shortage of water, as well as a lack of rainfall provides a weak renewal of groundwater, which can contribute to the accumulation of a higher concentration of carcinogens in groundwater and provide a high risk to public health. If policymakers in arid countries and decision-makers have effective water quality maps, then the country can be more efficiently managed water resources without risking the population. Originality/value: The current study is planned as a multi-stage, each of which is supposed to conduct field studies of groundwater and surface water quality with appropriate parameters, analysis of institutional reports and related scientific studies in order to create an effective water quality map for rational water use.

Opis:: The idea of sustainable development imposes waste management tasks that can be solved only using a systemic approach. It requires that municipal waste management is carried out in a technically correct manner, is economically efficient, socially acceptable, with no negative effect to the natural environment and takes into account economy of all waste streams, including electrical and electronic waste (E-waste). A relentless pursuit of comfort, quality of life as well as rapid technological changes result in products of a shorter life cycle, which quickly become just electro scraps. There are many of them with a different composition. E- waste may include e.g. toxic metals, which if released to the environment may pose a threat to human life and health. At the same time, recovery of valuable secondary raw materials complies perfectly with implementation of the principles of sustainable development. In recent decades, the risk assessment for the natural environment and decision-making strategies have become a target of intense and complex research undertaken also in the waste management area. The main objective of risk assessment is providing a rational basis to make unbiased decisions about the system. The article attempts to identify and assess risks of an environmental impact resulting from negligence or operational disturbances in a system of recovery and recycling of electrical and electronic waste.
Filozofia zrównoważonego rozwoju narzuca gospodarce odpadami zadania, które mogą być rozwiązane tylko w przypadku traktowania jej w sposób systemowy. Ujęcie systemowe wymaga zapewnienia aby gospodarka odpadami komunalnymi była rozwiązana w sposób technicznie poprawny, ekonomicznie efektywny, społecznie akceptowany i nie oddziaływujący negatywnie na środowisko przyrodnicze oraz uwzględniała gospodarkę wszelkimi strumieniami odpadów, w tym również zużytym sprzętem elektrycznym i elektronicznym. Nieustające dążenie do komfortu, poprawy jakości życia oraz gwałtowny postęp technologiczny, powodują powstawanie produktów o coraz krótszym cyklu życia, które stają się właśnie elektrozłomem. Poza faktem, że jest ich dużo istotne znaczenie ma również ich skład. Elementy elektrozłomu zawierają m.in. metale toksyczne, których uwolnienie do środowiska może wpłynąć na jego skażenie, co w rezultacie będzie stanowić zagrożenie dla zdrowia i życia ludzi. Równocześnie odzysk tych cennych surowców wtórnych wpisuje się w realizację zasad zrównoważonego rozwoju. Ocena ryzyka dla środowiska naturalnego i strategii podejmowania decyzji w ciągu ostatnich kilkudziesięciu lat stają się celem intensywnych i złożonych badań, podejmowanych również w zakresie gospodarowania odpadami. Zasadniczym celem oceny ryzyka jest dostarczenie racjonalnych podstaw do podejmowania wyważonych decyzji dotyczących danego systemu. W artykule podjęto próbę rozpoznania i oszacowania ryzyk oddziaływania na środowisko naturalne wynikających z zaniedbań lub nieprawidłowości funkcjonowania systemu odzysku i recyklingu odpadów elektrycznych i elektronicznych.

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 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:: This study aimed to analyze the heavy metal contamination in sediments and their potential ecological risks. The sediment samples were collected using PVC pipes and grab samplers at nine study sites in Youtefa Bay, namely five sites in the mangrove ecosystem, two sites in the estuary, and two sites in the middle of the bay. The heavy metal content was analyzed using Atomic Absorption Spectrophotometry. The results of the analysis of the heavy metal content in the sediment were in the following order: Zn > Cu > Pb > Ni > Cr > Cd > As > Hg (106.077±98.857, 28.553±30.505, 19.798±11.541, 17.665±11.457, 12.103±0.124, 2.996±1.235, 0.149±0.124, and 0.082±0.047 mg kg-1, respectively). Only the Cd content has exceeded the Threshold Effect Level (TEL) at all study sites. On the other hand, the As and Cr content has not exceeded TEL at any study site. The content of Hg, Cr, Pb, Zn, and Ni has exceeded TEL only at a few study sites. The heavy metal content in estuary sites is higher than in mid-bay and mangrove sites, which can provide the information on the sources of heavy metal contaminants. There is a significant correlation for the content of Cu, As, Pb, Cd, Zn, and Ni which can indicate that the sources of these heavy metals are relatively the same (r = 0.569 to r = 0.950). The CF and Igeo values indicate that there has been contamination of several heavy metals studied. Further analysis ( ERI ) showed that the heavy metal content in the sediments poses a potentially serious ecological risk. Most of the potential ecological risks are the contribution of Cd and Hg which have high toxicity factors and this should receive special attention from local governments and stakeholders to prevent higher contamination.

Opis:: Municipal refuse may increase heavy metal concentration in soil, even at low levels, and their resulting long-term cumulative health effects are among the leading health concerns all over the world. In this study, we investigated the concentration of heavy metals in soils and edible plant leaves grown in an abandoned dumpsite along Akachi road in Owerri municipality. The soil samples were collected at each plot using a soil auger at the depth of 0-10 cm. Leaves of dominant edible plant species were selected and collected from each sample plot. The samples were dried in an oven with forced air at 40 °C, milled to fine powder then digested with 10 ml concentrated HNO3 and 5 ml concentrated HClO4 and were analyzed for Cr, Cu, Fe, Mn, Al, and Zn, using an H183200 MultiParameter Bench Photometer. Result showed that metals in in the sampled soils included (in order of quantity) Cr: 150-280 >Fe: 116.50-203 >Cu: 12.4-18.8 >Mn: 0-20 >Al: 0.08-0.16 >Zn: 0-1.4 mg kg-1 Dw. Moreover, levels of metals in the edible plant leaves are in the order of: Zn>Fe>Cu>Al>Mn>Cr. Zn, in particular, was higher than FAO/WHO recommended limits. Still, application of Pollution Load Index and Ecological risk models showed that the area is unpolluted and safe for use. Daily Metal Intake estimates indicated that zinc is mostly consumed from the plant species. The trends in Transfer Factor for the heavy metal in vegetable samples studied were in order: Zn>Al>Cu>Mn>Fe>Cr. Therefore, abandoned solid waste dumpsites contained significant concentrations of heavy metals which are later absorbed and accumulated by plants growing it.
