Pentachlorophenol - an environmental pollutant: Microcalorimetric investigations of an ecological model system

Abstract The influence of pentachlorophenol (PCP) on components of an ecological system was determined calorimetrically. After exposure to PCP at concentrations up to 0.4 g/l there was a significant stimulation to as great as 400 % of the rate of heat production in litter, soil and earthworms as a typical animal for this biotope. Even with the highest concentrations used no inhibitory effects could be detected in the present investigation.
