The LC50 of P. guillelmi for 7 and 14 d were 4285±339 mg/kg and 3207±248 mg/kg, which shows P. guillelmi can tolerate a higher concentration of lead nitrate. The average weight of the surviving earthworms decreased at concentration of 2800 mg/kg, and the locomotor ability of earthworms exposed to a range of soil lead concentrations showed a general decrease with increasing lead concentrations. We also presented data depicting the sperm morphology of earthworms, which shows potential as a sensitive biomarker for measuring effects of heavy metal on reproduction. 收起<<
