Wstepna ocena przydatnosci biokinetycznego modelu zintegrowanego narazenia na olow [IEUBK], do szacowania narazenia dzieci przedszkolnych

Oceniono przydatność modelu IEUBK do szacowania narażenia środowiskowego dzieci na ołów, w oparciu o porównanie wartości stężeń ołowiu we krwi, wyliczonych za pomocą modelu i stężeń oznaczonych. Stwierdzono, że oszacowane poziomy ołowiu były ok. dwukrotnie wyższe od stężeń oznaczonych we krwi dzieci.

The IEUBK model was evaluated for its applicability in the assessment of environmental exposure of pre-school children to lead and in making decisions on preventive and remedial measures. Children's blood lead levels determined by the IEUBK model were about two times higher than the true blood lead concentrations. It seems worthwhile to explain the sources of those discrepancies by undertaking a somewhat wider analysis of the input data used in the model and those suggested for use in the IEUBK model. Our results suggest that, in its current form, the IEUBK model is not sufficiently reliable to be used as an independent method for the determination of blood lead levels in Polish pre-school children.
