Increased VOC emissions can lead to unhealthy amounts of these toxins in the air, creating poor air quality that can have a negative effect on health. While emission controls on precursor gases such as volatile organic compounds (VOCs) and nitrogen oxides (NO x) have led to decreases in O 3 levels and extreme O 3 events in North America and Europe, parts of Asia including South Korea have seen increasing long-term O 3 trends (Chang et al., 2017; Fleming et al., 2018). About 4.5 million pounds of pesticides are used each year in the Willamette Basin to control weeds, insects, and other pests in agricultural and urban settings (Rinehold and Witt, 1992).Many pesticides are relatively soluble in water, whereas others attach strongly to soil particles.

Many biogenic processes also release carbon-containing molecules. A correlation analysis using an ensemble of marker volatile organic compounds suggests that secondary formation, not direct emission, is the major source driving ambient HCOOH. The United States Environmental Protection Agency has estimated that over 111 million people reside in areas that exceed the National Ambient Air Quality Standards for ozone. For instance, when people, animals and other aerobic organisms breathe, they exhale carbon dioxide, or CO2, which is essential for algae, cyanobacteria and plants that survive using photosynthesis. https://www.sciencedirect.com/science/article/pii/S1352231099004653
Many plants actually give off harmful chemicals as well as absorb them. Humans also have a significant effect on otherwise-normal VOC-causing processes, such as vegetation growth, soil activity and biomass burning. While many people are familiar with the anthropogenic forms of these often-unhealthy chemicals, they aren't only created by humans. Films of biogenic compounds exposed to the atmosphere are ubiquitously found on the surfaces of cloud droplets, aerosol particles, buildings, plants, soils and the ocean.
