Assembly and Curation of Lists of Per- and Polyfluoroalkyl Substances (PFAS) to Support Environmental Science Research

Frontiers in Environmental Science, 2022
Per- and polyfluoroalkyl substances (PFAS) are a class of man-made chemicals of global concern for many health and regulatory agencies due to their widespread use and persistence in the environment (in soil, air, and water), bioaccumulation, and toxicity.

A Model Assessment of the Occurrence and Reactivity of the Nitrating/Nitrosating Agent Nitrogen Dioxide (^•NO₂) in Sunlit Natural Waters

Molecules, 2022
Nitrogen dioxide (•NO2) is produced in sunlit natural surface waters by the direct photolysis of nitrate, together with •OH, and upon the oxidation of nitrite by •OH itself. •NO2 is mainly scavenged by dissolved organic matter, and here, it is shown that

Essence of Environmental Chemistry

International Journal of Engineering Research and Advanced Technology, 2020
Environmental chemistry studies the occurrence, movements, and transformations of chemicals in the living environments.  It is an interdisciplinary field that studies the presence and impact of chemicals in soil, water, and living environment. It deals with the impact of  chemicals and their effects on human health and organisms in the environment.
