I want to improve my knowledge on ecotoxicology/aquatic toxicology. Whereas there are many book available. Do you have a good recommendation? Thank you very much!
You can study books such as 1) Ecotoxicology Essentials, 2) Ecotoxicology: A comprehensive treatment, please see /paste the following link in search engine.
Aquatic Chemistry: Chemical Equilibria and Rates in Natural Waters, Edition 3 by Werner Stumm and James J. Morgan is a fantastic read that uses case studies to illustrate some of the fundamental skills required to be an ecotoxicologist.
I believe Aquatic Ecotoxicology: Advancing Tools for Dealing with Emerging Risks is a good and comprehensive book on the matter. Check out the table of contests here: https://www.sciencedirect.com/book/9780128009499/aquatic-ecotoxicology#book-description
