You should know
VOCs, also known as Volatile Organic Compounds, are gases emitted into the air from products or processes. They are widely used in various industries and products like paints, varnishes, wax, disinfection and even cosmetic products. Since there is such a wide variety of pollutants, health risks also vary greatly depending on levels of exposure and length of time exposed. Some effects include eye, nose, and throat irritation, headaches, loss of coordination, nausea, liver, and kidney damage.
