Association between renal function tests and pentachlorophenol exposure.

Data are presented and renal function tests and Pcp measurements on consecutive blood and urine samples collected from 18 workers at a wood treatment plant before, during, and after a 20-day vacation. Pcp concentrations in blood averaging 5.1 ppm before vacation fell to 2.2 ppm during vacation but with a temporary rise early in this nonexposure period, suggesting a body tissues store of Pcp which was mobilized in response to a negative Pcp balance. Urine Pcp concentrations showed similar but less marked variations. Creatinine clearance and phosphorus reabsorption values were depressed before vacation but showed significant improvement during vacation, suggesting that Pcp exposure reduced both glomerular filtration rate and tubular function, with recovery following a nonexposure period.

[Preliminary study on anaerobic bioremediation process for pentachlorophenol (PCP)-contaminated soil].

The performances of soil-slurry process with supplement of anaerobic granular sludge for remediating PCP-contaminated soil was investigated. The results showed that inherent anaerobic microbes in soil exhibited a little dechlorinating activity for simulative contaminated soil with 30 mg.kg-1 of PCP, the average PCP degradation rates within 28 d was 0.258 mg.kg-1.d-1. In soil slurry processes with 5 g.kg-1 granular sludge at aerobic, aerobic/anaerobic and anaerobic operation, the average PCP degradation rates within 28 d were 0.269, 0.291/0.842 and 0.892 mg.kg-1.d-1, respectively. PCP degradation rates were increased with increasing the amounts of anaerobic granular sludge, 0.834, 0.843, 0.928 mg.kg-1.d-1 of the average PCP degradation rates within 35 d were achieved in soil slurry processes supplemented with 5, 10, 25 g.kg-1 of granular sludge, respectively. This bioremediation process also presented higher initial PCP degradation rate for higher concentration(60 mg.kg-1) of PCP in soil.
