Acute and chronic toxicity tests with lindane were conducted on Daphnia magna. The 24-hr static LC50 was 1.64 mgL-1. The sublethal effects of 0.16, 0.25, 0.32, 0.60 and 0.80 mgL-1 lindane on the survival, reproduction and growth of D. magna were monitored for 21 days. The algae Nannochloris oculata (5 × 105 cellsmL-1) was used to feed the daphnids. The parameters used to determined the effect of the pesticide on D. magna were:mean total young per female, mean brood size, days to first brood, intrinsic rate of natural increase (r), growth, and survival. Reproduction as well as survival was significantly reduced at lindane concentrations of 0.25 mgL-1 and higher. The intrinsic rate of natural increase (r) decreased with increasing concentrations of lindane. Growth, as measured by body length, was depressed significantly at 0.25 mgL-1 lindane and higher. The chronic data was used to formulate an acute/chronic ratio. |
