In the present study, the toxic effects of TCS on a terrestrial snail
(Achatina fulica) were tested. The A. fulica was often used to determine
the biochemical and other toxic effects of chemicals (Rao and
Singh, 2002; Chandran et al., 2005; Salway et al., 2010). The aims of
this study were to (1) determine the toxic effect of TCS on the biomass,
shell diameter growth, and total food intake of A. fulica; (2)
determine the toxic effect of TCS on the activity of SOD, CAT, and
POD, and the content of MDA. This work could provide valuable
information for the environmental risk assessment and pollution
management imposed by TCS in the terrestrial environment
conducted on terrestrial organisms, as confirmed by Lin et al.
(2010), who examined the biochemical and genetic toxicity of
TCS on Eisenia fetida. Therefore, further studies need to be performed
on TCS toxicity.
