I thought that was strange too - and why did they only focus on “endocrine”, what about neurotoxicity and other things?
How do you test "neurotoxicity" in fish and shrimp?? It's difficult to do mental ability tests on them.
And they "did" test for other things besides endrocrine disruption (like total toxicity). The reason for testing for endocrine disruption is that it is the new "buzz phrase" for BAD, BAD, CHEMICAL.
