Abstract
This article traces the evolution of water toxicology into water eco-toxicology, demonstrating how early enthusiasm for protecting aquatic environments laid the foundation for the contemporary multidimensional field. The interchangeability of terms, such as "water toxicology" and "eco-toxicology," is explored, with a focus on key concepts and the contributions of notable researchers. Despite limitations in comprehensive coverage, the article highlights the ongoing relevance of water toxicology challenges and future directions in water eco-toxicology research.
