Study Details Toxic Elements Found in Stranded Whales, Dolphins Over 15 Years

Researchers evaluated the prevalence, concentration and tissue distribution of essential and non-essential trace elements, including heavy metal toxicants in tissue (blubber, kidney, liver, skeletal muscle, skin) and fecal samples. Findings reveal how toxicant levels relate to their sex, breed, age and other demographic factors.

Enhanced Arsenic Detection in Water, Food, Soil

In Journal of Applied Physics, a team of scientists fabricate sensitive nanostructured silver surfaces to detect arsenic, even at very low concentrations. The sensors make use of surface-enhanced Raman spectroscopy: As a molecule containing arsenic adheres to the surface, it’s hit with a laser and the arsenic compound scatters the laser light, creating an identifiable signature. The technique is a departure from existing methods, which are time-consuming, expensive, and not ideally suited to on-site field assays.

Epitranscriptomics, Xenobiotic Nuclear Receptors, Arsenic Exposure, and More Featured in May 2021 Toxicological Sciences

How Did Red Algae Survive in Extreme Environments?

Red algae have persisted in hot springs and surrounding rocks for about 1 billion years. Now, a Rutgers-led team will investigate why these single-celled extremists have thrived in harsh environments – research that could benefit environmental cleanups and the production of biofuels and other products.

Natural Toxins in the Global Food Supply Continue to Threaten the Health of Underprivileged Communities

Naturally occurring chemicals in the global food supply are known to pose a burden on worldwide health. New studies have found that a certain foodborne toxin, in addition to its known health effects,, is also linked to vaccine resistance, and for the first time the global burden of disease from foodborne arsenic, lead, cadmium, and methyl mercury has been quantified.. The Society for Risk Analysis (SRA) will present new studies as part of its Global Disease Burden Caused by Foodborne Chemicals and Toxins symposium on Monday, Dec. 9 from 1:30-3:00 p.m. as part of its 2019 Annual Meeting at the Crystal Gateway Marriott in Arlington, Virginia. This symposium will provide updates to a 2015 World Health Organization (WHO) publication which analyzed the disease burdens caused by these toxins.
