This informative text takes a look at the problem of long-term exposure to low-level concentrations of toxins. In addition to commonly found toxins, such as chemical fumes from furnishings and carpeting, and indoor use of pesticides, this unique volume discusses risks associated with exposure to indoor allergens and infectious disease pathogens such as Legionnaires Disease. Because few scientific models exist for understanding the dynamics of indoor air quality, Risk Assessment and Indoor Air Quality is an essential resource for all students and professionals involved evaluating, testing and monitoring indoor air quality.
