Toxicity pathways of chemicals in aquatic organisms


To define safe concentrations for all species in an ecosystem, species sensitivity distributions and extrapolations are applied to acute and chronic toxicity data. How can adverse outcome pathways help to better understand the ecotoxicity across different trophic levels?

What are the commonalities and differences of adverse outcome pathways of baseline toxicity in algae, daphnia and fish?

What is the difference between the inhibition of the acetylcholinesterase by organophosphates and carbamates?
