EFFECT OF PENTACHLOROPHENOL ON SELECTED SOIL ENZYME ACTIVITIES IN A CHILEAN ANDISOL
The activities of laccase, Mn-peroxidase, phosphatase and dehydrogenase were studied in a Chilean Andisol (Temuco Serie) contaminated with pentachlorophenol (PCP). Experiments were conducted on the top of 0-20 cm soil, adding different concentrations of PCP (0.41, 4.1 and 41 mg kg-1). Enzymatic acti...
