Introduction Ineris works to improve our knowledge of chemical substances and physical agents, environmental pollution (air, water, soil), and industrial facilities, their impact on humans, goods, and the environment. The Institute also conducts studies on measures that can be taken to prevent or reduce these impacts. Its expertise is founded in research and knowledge of the field across four competency areas: Physical and chemical measurements to characterize emissions (industrial or otherwise) and air, water and soil quality. Ineris works both to standardize practices and in evaluating and developing new methods. Development and implementation of predictive models to further understand the behaviour of pollutants in the atmosphere, socio-economic analysis to organize pollution management policy across different geographical areas. This area of expertise also helps organize restrictions on chemical substances. Evaluation of toxicity and ecotoxicity of substances and of physical agents in order to assess their impact on living organisms. Subjects investigated include endocrine disruptors, nanoelements, electromagnetic fields and more. Evaluation of health risks related to industrial facilities and polluted soils, as well as the study of clean, sustainable technologies and processes to reduce such risks.
