Ecotoxicology Service Overview

Toxicology is the science that studies toxic substances, their etiology (origin), their contact and effects on organisms (target organs) and on the environment (ecotoxicology), and the means to detect and eliminate or reduce them. Ecotoxicology, a scientific discipline at the interface between ecology and toxicology, studies the behavior (fate) and the effects of artificial or natural pollutants on ecosystems.
Ecotoxicological tools are used for the fate and effects (toxicity) assessment of contaminants present in wastewater, municipal and industrial effluent, receiving water, groundwater, landfills, soils, sediments, sludge, chemical substances, and products. AGAT Laboratories provides full-service environmental toxicology analyses (toxicity tests) of water, soils, and sediments, including effluent testing for industries to meet provincial and federal government compliance regulations. Our Ecotoxicology department, based in Montreal (QC) offers analytical services to our clients across the country. Our laboratory can test according to the daily, weekly, monthly and yearly requirements of key regulatory bodies. Our strong and diversified world-class team includes senior environmental toxicologists, biologists, and chemists who provide a range of services from routine toxicity testing to special projects that require toxicological or chemical tools, customized assessment methods, technical / scientific reports, or research / development. AGAT is your best choice for routine and specialized toxicity testing.
