In spite of existing prohibition PCP is playing an important role in enviro
nmental medicine, because of existing persistence, toxicity and ubiquitous
occurence. Because of insufficient datas especially for the eastern German
region PCP background levels of house dust samples and urines of children o
f the city of Leipzig and of the small-towns Hettstedt, Wippra, Roitzsch an
d Greppin were determined and compared with existing reference levels. The
house dust samples and the urines of the children of Leipzig were lower bur
den than the samples of the small-towns. Most of house dust and urine had c
oncentrationes in the range of reference area legally for the general popul
ation. A correlation of the content of PCP in house dust and urine could no
t be established.
