To meet the sustainable development goals (SDG), adopted by the UN 70th general assembly in, December 2015, advances in analytical and sensing chemical techniques for an objective appraisal of the fate and effects of anthropogenic chemicals in our environment will be more than ever desirable. This symposium will therefore focus on integrated studies of pollutants or any species disseminated in our environment as a result of human activities combining advances in analytical chemistry and toxicity risks assessment. It should address sampling, preparation and detection strategies for quantification in the laboratory and in industries, as well as developing in situ chemical and biochemical sensing and monitoring techniques. The compartments of our biosphere to be surveyed are highly diverse and interacting at multiple scales as complex systems: air, fresh and sea waters, soils and underground formations, living organisms including ourselves. The presentation of computer models of pollutants propagation from sources up to metabolic compartments should be helpful but mostly to motivate the significance of chemical analyses and enlight socially responsible decisions. Species of interest encompass for instance airborne particles, diesel nanoparticles and their precursors, radiogenic compounds, explosives and their residues, hydrocarbons, synthetic organics, metals, acid oxides or inorganics: this list in not exhaustive. Analytical information that is required includes elemental quantification and speciation, but also size distribution, morphologies and surface properties of nanoparticles. The impact of microfluidic techniques on sampling, preparation and detection in the laboratory is expected. Other emerging techniques akin to bio-sensing like EDA (Effect Directed Analysis) are also fully in the scope of the symposium. Sensors for in situ monitoring are obviously of growing importance, and also a significant economic sector: this symposium should also help identify breakthroughs in terms of gassolid, electrochemical and biochemical devices, as well as applications of data science in the field of analytical chemistry. Communications on remediation engineering will be more welcome by symposium 3.4 “Catalysis, Sorption and Separation for a Cleaner Environment”
