Praćenje sadržaja teških metala u padavinama u nenastanjenoj oblasti Kamenički vis

Abstract

Industrijski razvoj i urbanizacija nameću intenziviranje procesa proizvodnje često putem prekomernog trošenja ograničenih prirodnih resursa i na račun kvaliteta životne sredine. Kao kompromis između suprotstavljenih interesa globalnog privrednog razvoja, sa jedne strane, i očuvanja životne sredine, sa druge, koncept 'održivog razvoja' povezuje privredni, socijalni i kulturni razvoj i promoviše usklađivanje takvog razvoja sa potrebama i ograničenjima životne sredine. Praćenje nivoa zagađujućih materija u medijumima životne sredine ukazuje na neophodnost usvajanja koncepta 'održivog razvoja'. Cilj ovog istraživanja je bio da se stekne uvid u stepen zagađenosti atmosferskih padavina kroz praćenje i procenu prenosa teških metala. Koncentracije teških metala određivane su u uzorcima padavina sakupljenim na GAW/EMEP stanici Kamenički Vis, tokom 2008. i 2009. godine. Za prikupljanje padavina koršćena je bulk (suvo-mokra) metoda, a koncentarcije odabranih metala (Fe, Al, Zn, Cu, Pb, Mn, Ni i Cd) određivane su ICP-MS metodama. Dobijeni rezultati ukazuju na povećanje maksimalnih koncentracija Fe, Ni, Cu, Pb i Mn u 2009. godini u odnosu na 2008. godinu, ali za potvrđivanje ovog trenda potrebna su višegodišnja merenja, koja su u toku.

Industrial development and urbanization impose intensive production usually through excessive use of limited natural resources and degradation of the environment. As a compromise between opposing interests of global economic development, on one side, and environmental protection, on the other, concept of 'sustainable development' links Industrial, social and cultural development and promotes balancing of such development with environmental needs and restrictions. Necessity and importance of adoption of such concept can be seen through monitoring of pollutants levels in all mediums of the environment. The aim of this investigation is to gain an insight into the composition of atmospheric precipitation through monitoring and analysis of heavy metal transport in the atmosphere. Heavy metal concentrations were determined in the samples of atmospheric precipitation collected on GAW/EMEP station Kamenički Vis, during 2008 and 2009. Precipitation samples were collected using bulk (dry-wet) method. Content of selected heavy metals (Fe, Cu, Zn, Al, Pb, Ni, Mn and Cd) in precipitation samples was determined using inductively coupled plasma mass spectroscopy (ICP-MS). Obtained data shows an increase in concentration levels of Fe, Ni, Cu, Pb and Mn in 2009, compared to 2008, however further long-term measurements are necessary in order to confirm this trend. Such investigation is underway.
