Urinary organophosphate metabolite levels in Palestinian pregnant women: results of the Middle East Regional Cooperation Project.

The purpose of the study was to measure urinary organophosphate (OP) metabolites in Palestinian pregnant women, and to compare levels with those in pregnant women in Jerusalem and women from the general population in Israel. We measured six dialkyl phosphates in urine samples collected from 148 pregnant women from the West Bank area. Median total dimethyl phosphate (DM(total)) levels were significantly lower in Palestinian women compared to Jerusalem pregnant women and women in Israel (p = 0.
