Abstrakty
The aim of this work was to identify concentration levels of different chemical forms of mercury (TGM, TPM) in the ambient air in selected areas of the Silesian Region, characterized by low and high mercury emission. Based on the obtained data TGM and TPM concentration levels were determined. The project also focused on determination of dry and wet deposition of mercury compounds. Data concerning TGM and TPM flux rates in the ambient air and data on mercury deposition were used to determine a deposition coefficient. The coefficient was calculated as a share of mercury deposition on the land surface (dry and wet) to the amount of this contaminant transported with loads of air in the form of TGM and TPM in a given measurement station. At both monitoring stations the deposition coefficient did not exceed 0.2 %. The idea of calculating the deposition coefficient based on the analysis of TGM and TPM flux rate is a new solution. The proposed deposition coefficient allows to quantify information on a selected contaminant concentration and its potential impact resulting from deposition. Further studies on the deposition coefficient may contribute to the development of methods for estimating the impact of contaminants contained in the ambient air on other environmental components based on the analyses of the contaminant flux rate.
Głównym celem tego projektu było określenie poziomów stężeń specjacyjnych form rtęci (TGM, TPM) w powietrzu atmosferycznym na wybranych obszarach Województwa Śląskiego charakteryzujących się zróżnicowanym oddziaływaniu źródeł emisji zanieczyszczeń powietrza. Na podstawie uzyskanych danych pomiarowych określono poziomy stężeń TGM i TPM jakie występują na badanym obszarze oraz wyznaczono wielkości suchej i mokrej depozycji związków rtęci. Na podstawie otrzymanych danych dotyczących natężeń strumieni TGM i TPM a także danych o wielkości depozycji związków rtęci wyznaczono wartość współczynnika depozycji rtęci. Współczynnik ten można scharakteryzować jako udział natężeń strumieni TGM i TPM napływającymi z masami powietrza do punktu pomiarowego w stosunku do suchej i mokrej depozycji rtęci w danym punkcie pomiarowym. Rozwiązanie dotyczące wyznaczenia współczynnika depozycji, które opiera się na analizie przepływów rtęci w powietrzu jest podjęte po raz pierwszy zarówno na świecie, jak i w Polsce. W przeprowadzonych badaniach wartości współczynnika depozycji rtęci nie przekroczyła 0,2%. Zaproponowany współczynnik depozycji daje możliwość powiązania w sposób ilościowy informacji o poziomach stężeń analizowanego zanieczyszczenia w powietrzu atmosferycznym z możliwością jego oddziaływania w wyniku depozycji. Rozwój idei współczynnika depozycji może w przyszłości prowadzić do stworzenia systemu oceny oddziaływania zanieczyszczeń zwartych w powietrzu atmosferycznym na inne komponenty środowiska poprzez analizę strumieni napływu tych zanieczyszczeń.
