The U.S. Environmental Protection Agency (EPA) has announced of $7.7 Million in research grant funding to 11 institutions in order to develop and assess innovative methods in risk assessment of chemical mixtures.

This research will help us in understanding the potential risks the chemical mixtures present in the environment could pose to Human Health. These chemicals are present in air, water, soil, food and products of day-to-day use. They include per- and polyfluoroalkyl substances (PFAS), phthalates, polycyclic aromatic hydrocarbons (PAH), disinfection by-products (DBP) and other risky chemicals.

EPA suggests that the toxicity of the chemical mixtures must be analysed which could help us to learn how the human health and environment is affected when they are present as a compound and how it differs when the chemicals are present individually

New approach methods (NAM) and alternative animal models have emerged as likely approaches to advance the risk assessment of mixtures due to their lower cost and higher throughput.
