Sampling methods of emerging organic contaminants in indoor air

In recent years, there are growing concerns of emerging organic contaminants (EOCs) owing to their potential adverse impacts on human health. Lots of EOCs are used in civilian products and considered as primary contaminants in indoor environment. Developing efficient air sampling techniques are prerequisite to evaluate EOC contaminations in indoor environment. This article aims to review the temporal trends of indoor air sampling techniques of several typical EOCs, i.e. brominated flame retardants, phthalates, pharmaceutics and personal care products, and per-and polyfluoroalkyl substances. Although some progress has been made in this field, there is still a large gap to be filled in the monitoring of EOCs in indoor air.
