Trace organics refers to the study and analysis of organic compounds that are present in very small concentrations in natural environments such as water, soil, air, and biological systems. These compounds can include pharmaceuticals, pesticides, industrial chemicals, and other pollutants that may have harmful effects on the environment and human health. Trace organics research aims to understand the sources, fate, transport, and effects of these compounds in the environment, as well as develop methods for their detection and removal. This research area is important for environmental monitoring, risk assessment, and the development of strategies to mitigate the impact of trace organic pollutants.
