Abstract

Ecosystems are intricate networks of biotic and abiotic components that sustain life through complex interactions. However, the increasing presence of anthropogenic pollutants—such as heavy metals, pesticides, and industrial chemicals—threatens ecosystem function and stability. Toxicology, the study of the adverse effects of chemicals on living organisms, plays a pivotal role in understanding and mitigating these threats. This article explores how toxicological research identifies the mechanisms of pollutant toxicity, assesses their impacts on species and ecological processes, and informs strategies for ecosystem preservation. By integrating field studies, laboratory experiments, and predictive modeling, toxicology provides critical insights into bioaccumulation, biomagnification, and sublethal effects that disrupt food webs, nutrient cycling, and biodiversity. The discussion highlights case studies, such as the impact of DDT on avian populations and mercury contamination in aquatic systems, to illustrate toxicology’s contributions to ecological stability. Ultimately, this work underscores the necessity of toxicology in developing evidence-based policies and remediation efforts to safeguard ecosystems amid growing environmental pressures.
