Indoor Air Quality

Healthy indoor environments have become a critical part of overall health in today's society. Missourians on average spend 90% of their time indoors, at home, at work, and at play. While being inside has traditionally been thought of as a safe haven, recent studies have shown, unfortunately, that pollutant levels indoors are often much higher than those outside. Recent technology has created more energy efficient buildings, which while good, has also served to trap a wide variety of pollutants in homes, schools, and office spaces with too little fresh air. A heavy reliance on strong chemical cleaners, solvents, and pesticides has increased possible pollutant exposure levels, while improper construction can trap moisture leading to a build-up of biological pollutants such as dust mites, bacteria, or mold. Health effects from these indoor pollutants, ranging from asthma to headaches, to increased cancer risks to death from chemical poisoning, can result. Increasing the risk is the fact that our most vulnerable citizens to disease, children and the elderly, often spend the most time indoors. There are several laws at the federal, state, or local level that address these issues. However, there are still many gaps not covered by laws. In these cases DHSS provides guidance, assistance, and recommendations.
