New Method Detects How Ocean Biology Affects Sea Spray Chemistry
Scientists identify ocean biology that affects sea spray chemistry, atmospheric particles
PNNL and Los Alamos National Laboratory scientists devised a new method to identify the chemical composition of sea spray, and how that chemical make-up is affected by ocean biology. The new model provides a better description of microscopic sea organisms affecting ocean chemistry that in turn affects the chemistry of sea spray particles. The far-flung particles can loft high enough to affect cloud-forming droplets.
Man trumps dog: Earlier assumption about BPA exposure confirmed
New human study shows oral exposure does not create risk for high BPA exposure
Coating the mouth with BPA-containing food, like soup, does not lead to higher than expected levels of BPA in blood, a new study in Toxicology and Applied Pharmacology shows. The study authors, including PNNL's Justin Teeguarden, conclude that oral exposure does not create a risk for high exposures.
BPA, also known as bisphenol A, is used to make some plastics and to seal canned food containers against bacterial contamination. Food, which picks up trace amounts of BPA from packaging, is the major source of human exposure.
Research led by Dr. Xiao-Ying Yu, a scientist at Pacific Northwest National Laboratory and her team developed PNNL's System for Analysis at the Liquid Vacuum Interface, or SALVI, allowing—for the first time—imaging of liquid samples reacting in real-time and a realistic environment. They won a prestigious Excellence in Technology Transfer Award in 2015 from the Federal Laboratory Consortium for Technology Transfer (FLC).
