An August 15, 2016, U.S. Environmental Protection Agency (EPA) blog item describes EPA’s research on sunscreens containing engineered nanomaterials and how they might change when exposed to chemicals in pool water.  According to EPA, many sunscreens contain titanium dioxide engineered nanomaterials, which are often coated with other materials such as aluminum hydroxide to shield skin from reactive oxygen species.  EPA researchers are testing to see whether swimming pool water degrades the...

Inhalation Toxicology has published an article entitled “Exposure assessment of workplace manufacturing nanosized TiO2 and silver,” which monitored the possible exposure to nanoparticles at workplaces that manufacture nano-titanium dioxide (TiO2) and nano-silver.  The abstract states: To estimate the potential exposure of workers, personal sampling, area monitoring, and real-time monitoring using a scanning mobility particle sizer (SMPS) and dust monitor were conducted at...
