CAS MIXTURE

MIXTURE

This entry covers a chemical mixture—a blend of multiple substances. Mixtures are common in fuels, smoke, industrial emissions, and many products; health risks depend on their components and how they act together [1][2].

Where It Comes From

Manufacturing and combustion (traffic, wildfires, boilers), consumer products (solvents, cleaners, fragrances), building materials, spills, and waste sites [1][3][4].

How You Are Exposed

Breathing indoor/outdoor air, drinking water, eating contaminated food, and skin contact at work or home [1][2][3].

Why It Matters

Effects vary by components; mixtures may contain carcinogens and irritants, and combined exposures can add or interact to increase risk [1][2][5].

Who Is at Risk

Workers around engines/solvents, children, pregnant people, older adults, people with asthma or heart disease, and communities near industry or heavy traffic [1][3][4].

How to Lower Your Exposure

Ventilate; choose safer products; follow labels and PPE; keep smoke out; maintain engines; and use certified water/air filters suited to known contaminants [2][3][6].
