[Contamination of foods and feeding stuffs from selected areas of the district of Erfurt with lead and cadmium. 2. Burden in agricultural products in the effective range of a lead emitter as compared to a control area].
Using the inverse voltammetric method already described (cf. Part I), the authors determined the lead and cadmium contents in 126 forage samples and 86 cereal samples from the surroundings of a lead emitter (area A) and from the control area B. To assess the heavy metal burden in forage plants at different growth stages, 33 samples of plants taken from both areas at the first stage of growth, not yet used for feeding, were analyzed. The lead burdens in the samples from area A varied with the distance from the emitter, a works which processes pure lead. 20 of the 87 forage samples from this area exhibited lead contents greater than 10 mg/kg of dry matter. 11 of the 55 cereal samples (grains) there taken contained more than 0.5 mg of lead/kg of fresh matter. As expected, there was no correlation between the cadmium values and the lead contents. These results are compared with those obtained from samples from the control area (39 forage samples and 31 cereal samples). Conclusions are drawn as to the agricultural use of land in the area of the emitter.
