Exposure to environmental chemicals is an important risk factor for breast cancer

Read the full story from the Silent Spring Institute.

Exposure to environmental chemicals, especially early in life, is an important contributing factor in the development of breast cancer, according to the most comprehensive review of human studies to date. The findings could help inform prevention strategies aimed at reducing the incidence of the disease, as rates continue to increase worldwide.

Too little is known about the compounds in wildfire smoke

Read the full story in the Davis Enterprise.

How do fire-suppression chemicals and pesticides affect wildfire smoke and the health of those who breathe it? UC Davis graduate students discovered that this question cannot be answered based on current scientific evidence and, in a review published in “Current Topics in Toxicology,” they recommend studies on the compounds in wildfire smoke.

Federal panel votes to warn public about flame retardants in baby products, furniture

Read the full story in the Chicago Tribune.

For the first time a federal agency is moving to outlaw an entire class of toxic flame retardants, a policy change intended to protect Americans from chemicals linked to cancer, neurological deficits, hormone disruption and other health problems.

The Consumer Product Safety Commission voted Wednesday to immediately warn the public about the dangers of chemicals known as organohalogens in baby and toddler products, mattresses, upholstered furniture and electronics enclosures. The commission also set in motion what promises to be a contentious debate about new regulations prohibiting manufacturers from adding any halogenated flame retardants to products covered by the ban.

Antidepressants found in fish brains in Great Lakes region

Human antidepressants are building up in the brains of bass, walleye and several other fish common to the Great Lakes region, scientists say.

In a new study, researchers detected high concentrations of these drugs and their metabolized remnants in the brain tissue of 10 fish species found in the Niagara River.

This vital conduit connects two of the Great Lakes, Lake Erie and Lake Ontario, via Niagara Falls. The discovery of antidepressants in aquatic life in the river raises serious environmental concerns, says lead scientist Diana Aga, PhD, the Henry M. Woodburn Professor of Chemistry in the University at Buffalo College of Arts and Sciences.

Panel supports six disinfection byproducts as potential carcinogens

Read the full story in Environmental Factor.

A panel of scientific experts, convened June 24 by the National Toxicology Program (NTP), recommended that six chemical compounds known as haloacetic acids (HAAs) be classified in the Report on Carcinogens as reasonably anticipated to be carcinogens. HAAs are byproducts created when chlorine, chloramine, or chlorine dioxide are used to disinfect drinking water.

Substitution of PFAS chemistry in outdoor apparel and the impact on repellency performance

Philippa J.Hill; MarkTaylor; Parikshit Goswami; Richard S.Blackburn (2017). “Substitution of PFAS chemistry in outdoor apparel and the impact on repellency performance.” Chemosphere 181, 500-507. Online at https://doi.org/10.1016/j.chemosphere.2017.04.122.

Highlights

  • First study to compare PFAS and non-fluorinated repellent finishes for apparel.
  • PFAS chemistry for water repellency is over-engineering in outdoor apparel.
  • Significant benefits by switching to non-fluorinated finishes.
  • PFOA and PFOS can be minimized and eliminated from human and environmental exposure.
