dc.description.abstractThe influence of temperature on the acute toxicity of a technical formulation (86%) and pure formulation (99%) of pentachlorophenol (PCP) to less than 24-h-old Simocephalus vetulus neonates was determined with 48-h static toxicity tests. The technical grade PCP was significantly more toxic to S. vetulus than the pure PCP (P < 0.05). Sensitivity of S. vetulus to technical PCP also significantly increased with temperature (P < 0.05), but a significant temperature effect was not found with the pure PCP. The mean 48-h LC50 values for neonates exposed to technical PCP were 140 and 199 ug l⁻¹ at 22deg.C and 16deg.C, respectively, and for those exposed to pure PCP were 262 and 304 ug l⁻¹, respectively.en_NZ
