Developmental bisphenol S toxicity in two freshwater animal models.

Freshwater animals are exposed to anthropogenic contaminants and are biomonitors of water quality and models of the deleterious impacts of exposure. Sponges, such as Ephydatia muelleri, constantly pump water and are effective indicators of water-soluble contaminants. Zebrafish (Danio rerio), native to Southeast Asia, live in the water column and feed at the water-sediment interface and are exposed to both water-soluble and insoluble contaminants.
