pp′DDE contamination of the blood and diet in central European populations

In this study, the actual risk of DDT pollution to two European human populations was assessed by analysing DDT residues in the diet, which is the main route of pollution for man, and in the blood and placenta, which are components affecting organs and new generations, respectively. The Gdansk region was selected as representative of areas subjected to a recent DDT ban in Europe, while a rural area in Western Germany was considered representative of European regions where DDT use and production ceased many years ago. The results of three food series of food sampling carried out with market basket methods during 2003 showed that pp'DDE, which is by far the main constituent of DDT residues, was present in foods of animal origin and in cereals at rather high concentrations in both countries, and that a risk for human health cannot be excluded. The total daily intake was higher in Poland than in Germany, and agrees with the finding that body tissues, on the average, are more polluted in donors from Poland than those from Germany.
