ABSTRACT

Environmental pollution still remains a serious problem in some heavily industrialized regions of Poland. Among various xenobiotics prevalent in human environment heavy metals such as lead and cadmium are considered as most harmful to living systems. The main source of these metals for humans is food and water, therefore increased dietary lead and cadmium intake may cause functional disturbances of various body systems, especially in young developing organisms. The objective of this study was to evaluate the lead and cadmium content in daily food rations served at two selected Children Guardian Centres (CGC) located in the region of Copper Basin Legnica (Głogow and Polkowice), during winter and spring seasons in 1996. The lead and cadmium content was determined after dry mineralization of samples by the FAAS method with deuterium BC. It was found that the lead and cadmium content in daily food rations exceeded the PTWI limits for children and adolescents in both CGC. Moreover, seasonal and regional variations of the lead and cadmium content in daily meals were observed. Generally, higher levels of lead in food rations were determined in the winter season whereas the cadmium content was higher in the CGC in Głogow in comparison to Polkowice.
