Plant and animal testing encompasses experimental methods that use whole organisms or their tissues to assess biological responses to chemicals, drugs, genetic modifications, environmental stressors, or other interventions under controlled conditions. In plants, testing commonly involves growth assays, phytotoxicity and ecotoxicological evaluations, and phenotypic or molecular analyses following exposure or genetic manipulation. In animals, it includes in vivo toxicology, pharmacokinetics, efficacy studies, and behavioral or physiological assessments, often guided by standardized protocols and regulatory frameworks. These methods aim to elucidate mechanisms of action, dose–response relationships, safety margins, and translational relevance to ecosystems or human health, while increasingly integrating refinement, reduction, and replacement strategies.
Most environmental scientists believe that chemical pollution can and is negatively affecting people and wildlife, according to my team's recent survey.
