Fun fact: The LD50 (Lethal Dose for 50% of the population) of DDT for humans is quite high, ie. it's not very toxic for us at all. If it wasn't so bad for other species we'd probably still be using it. DDT is devastating for birds for example.
Additionally DDT is persistent in the environment, which means that it accumulates in organisms which results in it moving up the food chain to the top predators. Eagles for instance were particularly harmed by DDT in the environment.
[edit] Woops my bad, I initially said that the LD50 for humans is low which would mean that it's quite toxic. The opposite is true in fact.
I've been through this with someone else. It's actually toxic to humans. Lethal dose doesn't mean anything
It was probably me, small world eh.
And again I'm not claiming that it isn't toxic to humans, however the toxicity is low.
"Lethal dose doesn't mean anything" what are you even talking about?
On that note LD50 has been used for years exactly because it is a useful measure of toxicity by species.
