Abstract |
2,4-D and 2,4,5-T levels in plasma and urine of 4 spraymen in forestry work were monitored during a week of exposure and for 36h afterwards. Plasma levels ranged from the detection limit to 0.1-0.2µg/ml, and declined to near the detection limit overnight. The highest levels were in urine with means of 8 and 4.5µg/ml for 2,4-D and 2,4,5-T, respectively, and 3-14µg/ml and 1-11µg/ml, respectively, in the afternoon after a day of exposure. In another investigation, the mean 24h excretion in urine was 9mg 2,4-D and 1mg 2,4,5-T. None of the spraymen had clinical symptoms except one who showed a slight irritation of the eyes after direct contact with the spray liquid. Exposure to the substances could be best followed by determination of urine levels. Sampling should be in the afternoon of an exposed day or within a day following exposure. The lowest detectable concentration in urine is 0.05µg/ml for both substances. English summary. |
