Although the US and other countries have banned or restricted the use of bisphenol A (BPA) because of environmental and health concerns, it is still used in thermally printed receipts and labels. Now researchers report in a study in the ACS journal Industrial & Engineering Chemistry Research that they have developed potentially safer polymers that could replace BPA for printed papers.
The study shows that sampling headwaters where streams form can identify which landscapes are resilient enough to handle the rigors of farming and which are vulnerable to leaching toxic residue into waterways.
A new peer-reviewed clinical trial to be published in the February edition of Regulatory Toxicology and Pharmacology shows that regular use of e-cigarettes does not have any negative health impact on smokers.
We collected 118 soil samples from seven African countries and analyzed them for lead. Contamination levels ranged up to 14 percent lead. As the lead battery industry continues to expand, it is expected that the number and size of lead battery recycling plants will increase. There is an immediate need to address ongoing exposures, restrict emissions, and to regulate site closure financing procedures to ensure that we do not leave behind a legacy of lead contamination.
A public database of more than 300 substances used to dye hair will help accelerate research and development work on more sustainable hair color. North Carolina State University researchers say computer modeling can save years of lab work and millions of dollars.
Environmental DNA analysis makes it possible to detect water organisms without having to capture them first. For the first time, a team at the Technical University of Munich (TUM) systematically investigated the effect of various environmental factors on environmental DNA analyses. By doing so, the researchers have made an important step towards the standardized application of this method for the monitoring of water bodies.
What do 3,044 golden retrievers across the nation have in common? They are the principal players in the second published scientific paper from Morris Animal Foundation's groundbreaking Golden Retriever Lifetime Study, highlighting characteristics of the dogs in this landmark study including age, medical condition, preventive care and more.
Spotted owls and barred owls are being exposed to high levels of rat poison in northwest California, with illegal marijuana farms the most likely source point, according to a study led by the University of California, Davis. Proposition 64, which legalized recreational marijuana in the state, went into effect this month and is expected to intensify the issue.
Smoke plumes emanating from wildfires are swept high up into the air and spread over thousands of kilometers even days after a fire has been put out. The fine particles and harmful ozone contained in these plumes often have devastating effects on the air quality of US cities and consequently the health of their inhabitants.
The Red Sea has relatively low amounts of floating plastic debris in its surface waters due to fewer sources or faster removal.
