Olga Naidenko leads EWG’s peer-reviewed research program, with publications ranging from groundbreaking studies on the impact of the nonstick chemicals known as PFAS on the health of humans and wildlife to pesticide risk assessment and biomonitoring research. Olga’s scholarship highlights the importance of children’s environmental health and equity and diversity in science. In her doctoral and postdoctoral studies, her research addressed the molecular basis of immune system defense against microbial disease agents. Olga formerly held a prestigious American Association for the Advancement of Science policy fellowship at the Environmental Protection Agency Office of Water, during which she researched climate change and water quality standards.

he draft assessment for PHFxS is a stark reminder of just how toxic this chemical family is to human health at very low levels. This is further evidence that we must move much faster to dramatically reduce exposures to PFAS and phase-out all nonessential uses.

These new limits confirm that these chemicals are toxic at very low levels. While these six PFAS are some of the most well-studied PFAS, nearly every week there are new scientific studies documenting an increasing number of ways that the whole class of PFAS could damage our bodies and threaten our health.

People whose water contains TCE can be exposed not just by drinking it but also by inhaling it while bathing, washing dishes and doing other household activities. Communities across the country have water with potentially harmful levels of this toxic solvent, but many people don't know about the risk they face when they turn on the tap.

This is an important step toward protecting the health and well-being of Americans, since perchlorate has been linked to a range of serious health problems.

By requiring the EPA to use its authority to limit perchlorate levels in tap water, the court has ruled the agency must put public health over the interests of the defense industry.

The EPA proposal to allow chlormequat to be sprayed on crops that ultimately become the main ingredients in foods we eat, like cereals, is a serious mistake that puts the health and safety of the American public, especially children, at risk.
