Abbasi, S.A. and R. Soni. 1983. Stress-induced enhancement of reproduction in earthworm Octochaetus pattoni exposed to chromium (VI) and mercury (II) — implications in environmental management. Int. Jour. Environ. Stud. 22 43-47. 

Methylmercury compounds at concentrations of 25.0 mg Hg/kg in soil were fatal to all tiger worms (Eisenia foetida) in 12 weeks at 5.0 mg/kg, however, only 21% died in a similar period (Beyer et al. 1985). Inorganic mercury compounds were also toxic to earthworms (Octochaetus pattoni) in 60 days, 50% died at soil Hg levels of 0.79 mg/kg, and all died at 5.0 mg/kg (Abbasi and Soni 1983).
