Opis:
One of the most important air contaminants in Krakow is particulate matter (PM), especially during winter months. Deposited PM was sampled between November 2014 and January 2015 and November 2015 and January 2016. The PM deposition amounted to 0.0646 g/m2 per day in the centre of Krakow and 0.0328 g/m2 in the northern district of the city. The allowed value of annual dust deposits (0.547 g/m2 per day) was not exceeded. The XRD and SEM-EDS analysis showed that quartz, calcite, potassium feldspar, plagioclase, kaolinite, and gypsum were the main mineralogical components of the deposited PM. Only in a few samples were illite, dolomite, and apatite observed. Significant concentrations were measured (ICP-MS) for Ca, Fe, Mg, Al, K, Si, Na, and Mn, and high concentrations for Ti, Cu, Zn, As, Pb, Cr, Ti, V, Li, Sr and Ni. The highest estimated daily intakes (EDI) for resuspended PM, were stated for ingestion exposure pathway than for dermal contact, and finally for inhalation, both for children and adults, as well as, for carcinogenic and non-carcinogenic elements. The mean hazard quotient (HQ) values for all three exposure pathways decreased in the following order: Fe > Al > Zn > Mn > Sr > Cu > Ba > Cr > Pb > V > Ni > Li > As > Sn > Zr > Co > Cd > Be, for children and adults. The hazard index values for all elements in each exposure pathway (HIelem) and for single elements in all exposure pathways (HIpath) were <1, both for children and adults. The risk values from all three exposure pathways were unacceptable in the case of Cr, both for children and adults, and in the case of As for children. The total non-carcinogenic risk (HItotal) values in all three exposure pathways for all elements were <1, however in case of children the risk value pointed to a low risk level. The total carcinogenic risk (Rtotal) values in all three exposure pathways for As and Cr exceeded the acceptable level, both for children and adults.

Opis:
Optimal methods used in the analysis of waste material resulting from mining and processing of mineral resources that allow to assess the potential impact of waste on the environment, based on binding environmental laws regulating potential commercial utilization of waste were investigated. The paper is concerned mostly with mineral waste, constituting about 80% of all industrial waste generated. According to the principles of sustainable waste management, waste storage is considered to be the last resort. However, every year over 20% of the total amount of industrial waste generated is stored. That makes the amount of the already deposited materials, coming from the time when the commercial utilization was not common in Poland, even more considerable. When it comes to extensive, i.e. regarding great quantities, and long-term usage of industrial wastes, the identical composition of waste material coming from different batches is of the essence. Unfortunately, this condition is not always fulfilled, therefore chemical composition analyses need to be carried out for monitoring purposes. For the same reason the waste material used should also be tested to check whether the parameters of a given batch are within the limit values defined by the standards. Described methods are intended to facilitate waste characterisation with respect to their effect on the environment when used for commercial purposes. An individual method is never good enough to determine the full extent of environmental impact. It is therefore recommended to apply several methods in a logical sequence, depending on the type of waste material and its purpose.

Opis:
In this work, characterization of dolomite powder was carried out in order to specify possible industrial applications. After the technological use of dolomite aggregates, the remaining fine powder becomes a waste. Raw and calcined powder samples were subject to mineralogical, textural and chemical studies involving leaching tests. The results of the calcination process indicate that the carbonate minerals present in the material sample undergo complete decomposition to form oxides. After the calcination, the material is practically non-porous, and its surface area is more than five times lower than that of the raw material. However, due to the high content of calcia in the calcined sample (CaO > 45% wt.), the material cannot be used as an additive in cement. The leaching tests showed that the concentration of metals released from the dolomite powder is low enough to classify the material as hazardous waste according to the TCLP test. Moreover, the concentration of metals that can get into the environment does not exceed permissible values as set by Polish law. Thus, it is recommended and justified to carry out detailed tests for the purpose of environmental protection; i.e. wet flue gas desulfurization, heavy metals absorption, and CO2 capture.

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.
