Environmental Health

What is environmental health? Environmental health is the study of factors in our environment that can affect human health and disease. Environmental exposures cause hundreds of thousands of illnesses each year, including asthma and cancers. Environmental health professionals learn how to identify, prevent and control those exposures to protect health.

Freshwater harmful cyanobacterial blooms (HCBs) present a mounting threat to public health outcomes and lake ecosystem services. The current climate crisis is expected to intensify the occurrence of freshwater HCBs in recreational water bodies, their formation of potent toxins, and resultant human exposures.

Hair is a unique matrix for metal deposition, as it offers a “timeline” of prior exposures (Stadlbauer et al., 2005). This spatiotemporal relationship of exposures along the hair can make possible the estimation of time and duration of exposures.

This pilot study investigates the impact of regular and irregular flushing routines on microbial contamination in eyewash stations across a university, sampling a total of 70 eyewash stations.

A robust interconnection exists between wasted food and food insecurity. Over a million tons of food waste are generated each year in Washington State, with approximately 390,000 tons of edible food being disposed (Washington State Department of Ecology, 2022). These contrasting issues are intricately linked, with the resolution of one concern holding the potential to alleviate the other.

Communities across the western United States experience hazardous smoke exposures from multiple fire sources. As wildfires become more frequent and severe, smoke exposures stemming from these fires are also worsening. Prescribed burning is a promising forest management strategy that can mitigate future wildfire risk, but also contributes to biomass burning emissions and human exposure impacts.

Laws permitting growth and possession of cannabis for medicinal and recreational use are currently changing rapidly in the United States (U.S.) and internationally. (Carliner et al., 2017; Caulkins et al., 2018; Mahamad and Hammond, 2019) While cultivation and use of cannabis is still considered illegal by the U.S. federal government, multiple U.S.

Ambient air pollution such as fine particulate matter (PM2.5) has been demonstrated to have respiratory and cardiovascular effects and is hypothesized to be associated with the Alzheimer’s disease processes. Community-engaged research provides an opportunity for the public to learn about their neighborhood level exposures to ambient air pollution, health effects, and mitigation strategies.

Polychlorinated Biphenyls (PCBs) are persistent environmental contaminants that pose a significant public health risk including reproductive toxicity partly because they are endocrine disruptors. The lipophilic nature of PCBs increases the risk of developmental exposure due to placenta and breast milk transfer.

Anthropogenic impacts on marine ecosystems have developed into a dominating and formative force within coastal regions. One of the strongest influences within these coastal anthropogenic zones is the deposition and life cycle of marine plastic waste.

The use of chemical agents to eradicate pests and weeds is prevalent across both developing and developed countries, and it plays a crucial role in the agricultural sector by enhancing crop yields and minimizing losses.

King County, Washington currently ranks 3rd in the nation for the number of people experiencing homelessness. Amid an affordability housing crisis, the number of people experiencing homelessness continues to grow in Seattle. People in historically redlined communities of Seattle disproportionately experience homelessness because of gentrification.

Background: Asthma is a leading cause of childhood morbidity in the U.S. and a significant public health concern. The prenatal period is a critical window during which environmental influences, including maternal occupational exposures, can shape child respiratory health.

Fine particulate matter (PM2.5) air pollution is associated with excess morbidity and mortality and estimated to be the most important environmental risk factor for mortality globally. Ultrafine particles (UFPs) and PM2.5 from wildfire smoke (WFS), are both thought to be more toxic than ambient PM2.5.
