Volatile organic contaminants (VOCs) are organic compounds generated from different industrial processes around the world. VOCs are ubiquitous contaminants, and some can be genotoxic, mutagenic and act as endocrine disruptors, thus representing a risk to ecosystems and human health. High levels of VOCs have been reported in industrialized countries such as the US. In this module, students will explore how the distribution of VOCs has changed over time. Students will then compare types and concentrations of VOCs among the US states in the context of geography, urbanization, industrialization, and fossil emissions as contributing factors of air pollution.
