Analyzing Chemicals and Genes Yields Novel Insight into PAH Behavior
Research Brief - July 2021
A new NIEHS Superfund Research Program (SRP)-funded study revealed how polycyclic aromatic hydrocarbons (PAHs) breakdown and transform in the presence of ultraviolet A (UVA) light and titanium dioxide nanoparticle pollutants. Their findings have important implications for PAH cleanup, which may not consider how PAHs transform in diverse environments.

PAH cleanup may worsen toxicity
Environmental Factor - October 2018
According to research by Staci Simonich, Ph.D., some of the products formed during the breakdown of pollutants called polycyclic aromatic hydrocarbons (PAHs) may be more toxic than the original compounds.

Pavement sealcoat products may be more toxic than suspected
Paper of the Month - July 2016
A study supported in part by NIEHS showed that certain pavement sealcoats used on asphalt driveways and parking lots are significantly more toxic and mutagenic than previously suspected.

Study Identifies Novel compounds More Mutagenic than Parent PAHs
SRP News Page - February 2014
Researchers at Oregon State University (OSU) have discovered novel breakdown products that form when specific high molecular weight polycyclic aromatic hydrocarbons (PAHs) chemically interact with nitrogen.
