Where did you get the idea that the pesticides commonly used before the common use of neonicotinoids were less toxic?
(They might be less toxic to bees and the zooplankton mentioned in the OP, but they were more toxic to, e.g., human agricultural workers.)
- epanchin 7y agoBecause the fish were alive.
- tptacek 7y agoNo, organophosphates were killing the fish, even at very low exposures.
- epanchin 7y agosource? I can’t see that in the article. The article states that when neonicotiniods were used, fish stocks collapsed. From this, there are only two valid conclusions; Pesticides was not previously being used, or the previous pesticide was less dangerous.
- gcheong 7y agoOr there is some other factor they didn't control for.
- tptacek 7y agoI'm sorry, let me make sure I understand what you're asking. Are you seriously asking for a source to back up the claim that organophosphate pesticides can be toxic to fish?
- epanchin 7y agoI cannot see in the article that organophosphates were used around Lake Shinji before the introduction of neonicotinoids. I certainly can’t see in the article that more fish died before the introduction of neonicotinoids.
