Abstract: | The roe deer indicates the contamination of ecosystems with environmental chemicals. The influence of land use on the contamination of five different forest and agricultural ecosystems in Rheinland Pfalz was proven. The cadmium and lead content was measured in renal tissue of the roe deer. The organic chemicals PCB, α-HCH, Lindan, DDT, and DDE were investigated in kidneys and liver and correlated to adipose tissue. The following results have been obtained: Lead: The Pb-contamination was generally low in all ecosystems investigated. Cadmium: The Cd-values showed an area-dependend contamination of the organs. The data of the test organs from the forest sites and the semi-agricultural area were 2–4 times higher than the ZEBS-limit. The contamination of the animals corresponded to the wet deposition of Cd in the regions. σPCB: The PCB-results indicated a relativly high contamination of the ecosystems. The PCB-ZEBS-limit for the interior organs was surpassed in all areas.α-HCH, γ-HCH (Lindan): The uniformly low values of the HCH-group indicated that these compounds were probably not of ecotoxicological significance in the agricultural and forest regions.DDT, DDE: The results obtained showed a low background contamination in all ecosystems investigated. Areas with former high DDT-applications revealed higher values of DDE in the tissues. ZEBS: Central institution for the evaluation of chemicals in the environment (Bundesgesundheitsamt) |
