Children in the U.S. with higher levels of BPA in their bodies were more likely to have Attention-Deficit/Hyperactivity Disorder (ADHD), according to a study.

The study of 460 children across the U.S. aged 8 to 15 years old found that 11 percent of those with BPA levels higher than the median level had ADHD. In contrast, 3 percent of those children with BPA levels below the median had ADHD.

The research, published online last week in the Environment Research journal, adds to evidence that children's BPA exposure may alter brain development and lead to behavior problems such as reduced attention and hyperactivity. ADHD is the most common behavior disorder in U.S. children, causing them to have trouble concentrating and controlling their behavior.

Helsinki, 8 June 2016 -- In its preliminary evaluation, ECHA will aim to:

WASHINGTON -- Hundreds of cancer-causing chemicals are building up in the bodies of Americans, according to the first comprehensive inventory of the carcinogens that have been measured in people. EWG released the inventory today.

EWG spent almost a year reviewing more than 1,000 biomonitoring studies and other research by leading government agencies and independent scientists in the U.S. and around the world. The nonprofit research group found that up to 420 chemicals known or likely to cause cancer have been detected in blood, urine, hair and other human samples.

Right now, Dupont is involved in a civil trial over a chemical it had used to manufacture stain-resistant teflon, called C8. It's a test case -- one of six -- that will determine how the remaining 3,500 are dealt with.

Dupont, however, started to phase-out C8 from the market in 2014 after it was determined that it caused a number of cancers linked [to] thyroid and testicular issues. It has replaced it with C6, which is supposed to be safe.

The objective of this project is the identification of substances toxic to reproduction (in short: reprotoxins) which are relevant for workers' exposure via inhalation at a considerable number of workplaces in Europe and, thus, for which an indicative occupational exposure limit value (IOELV) under the Chemical Agents Directive (CAD) might be suggested.

Due to depleting natural resources, new environmental regulations and economic considerations, there is a constantly growing interest in using renewable resources. That is why, considering the growing awareness of environmental and waste management issues, green composites are increasingly promoted for sustainable development. Novel materials based on polylactic acid and different biomass wastes have been obtained and analyzed. The addition of biomass to a polylactic acid matrix resulted in more opaque materials, with decreased values of the water contact angle and acceptable values of mechanical properties. Thus, transparency decreased from 1.99 for polylactic acid to 0.94 for the material comprising pomace fibers. ...

The biomass residues under study represent sources of raw material that proved suitable for manufacturing new materials, which could reduce domestic dependence on petroleum-based thermoplastics.

Dow Chemical has debuted a new RecycleReady Technology that allows polyethylene-based barrier packaging to be recycled as part of existing grocery store drop-off recycling programs.

The technology aims to divert packaging waste from landfill or incineration, increase post-consumer recycling yields and aid the creation of a circular economy for plastics packaging, Dow says.
