Seasonal effects on concentrations of monomethylformamide in urine samples.
Eleven du Pont operators participated in a special dimethylformamide metabolite (monomethylformamide, MMF) urine monitoring study to investigate a possible seasonal influence on urine metabolite concentrations. Variables considered included urine volume, MMF concentration, MMF mass, urine specific gravity, and ambient temperature. Statistical analysis revealed a 13% reduction in urine volume under hot weather conditions as a cause of increased MMF concentrations. A correction for this change in urine volume should be made subjectively.
