Lambda-cyhalothrin and an isomer gamma-cyhalothrin not likely to be carcinogenic to humans [72]. 

Studies with lambda-cyhalothrin and the freshwater crustacean G. pulex have shown that shorter durations of exposure result in substantially less severe effects than maintained, long-term exposures [15], In this case there was a significant reduction in toxicity with decreasing exposure times, with an 18-fold reduction in toxicity with exposure for 1 h compared to that determined after exposure for 96 h. Given this inverse correlation with exposure duration and toxicity, effects under natural environmental conditions where water column concentrations of pyrethroids are expected to decrease relatively rapidly are again likely to be less than would be predicted from estimates of toxicity under standard laboratory conditions with maintained concentrations (see Sect. 5).
