Lead:

The lead/ first two sentences properly identify what the rest of the addition will be about.

Content:

" These chemicals can mimic the function of natural hormones in animals and cause havoc to the endocrine system"

-Relevant to the topic of aquatic toxicology.

"They can either bind to hormone receptors and act as if they are the natural hormone creating a cascade of reactions when not needed or they can block the receptor and not allow for the original hormone to bind."

-Perfectly explains and supports the first claim made. How chemicals mimic the function of natural hormones.

"There are many things that have been linked to endocrine disrupting chemicals such as gamete quality, reproductive physiology, inhibition of gametogenesis, development of intersex gonads, decreased fertility and abnormalities in sperm."

"Natural or synthetic estrogens lurking in the water could be shaping different organism and disrupting the development and behaviors of them. Behavior is also something that can be affected by estrogens because it has been shown that increased aggression has a correlation with high estrogen levels in the animal kingdom."

"These estrogens can affect fish populations in many negative ways by effecting their development, behavior and reproduction."

-Great additions as it answers the question "why is it important that these chemicals can mimic natural hormones?" I would suggest adding some type of explicative figure that shows an example of a chemical that mimics a natural hormone and what pathway it's related to. That would make it a little easier to understand.

"When situations like this occur, it is important to consider the entire species of fish in that aquatic body because since these estrogens are causing major disruptions, they could potentially interfere with species of fish that are endangered, threatened or keystone species in that ecosystem."

-I would suggest adding a bit of content that ties everything together of how these chemicals affect the ecosystem as a whole.

"Environmental estrogens can interfere with various pathways in molecular biology as was well and have been seen to interfere with many signal transduction pathways."

-Last sentence seems a little rushed, but does tie everything together. Maybe try expanding a bit on it, something stating how these chemicals, not just environmental estrogens, effect the ecosystem.

Tone and Balance:

I don't see any biased writing in your addition. Seems to be neutral and informative.

Images:

Like I stated earlier, I think some explicative images would help make things easier to understand, especially for a wiki article.References:

Good use of references, perfect to support the addition you've written.

Overall:

Great addition to the existing article over aquatic toxicology as it goes over why its important to understand the effects of these chemicals on aquatic environments. Kind of focuses heavily on environmental estrogens, maybe add other examples to round everything out.
