A new study lends further evidence to a suspected link between abnormal breast growth in young boys--called prepubertal gynecomastia--and regular exposure to lavender or tea tree oil, by finding that key chemicals in these common plant-derived oils act as endocrine-disrupting chemicals. The study results will be presented Monday at ENDO 2018, the Endocrine Society's 100th annual meeting in Chicago.
Chemicals found in a variety of routinely used consumer products may be contributing to the substantial drop in sperm counts and sperm quality among men in recent decades, a new study in mice suggests.
Studies by British American Tobacco show that airway tissue damaged on exposure to smoke was restored when exposed to vapor from glo rather than smoke. These results add to evidence that glo has reduced risk potential compared to cigarettes. glo is a tobacco heating product designed to heat rather than burn tobacco. Tests show that glo heated tobacco vapor has around 90-95 percent less of certain toxicants than cigarette smoke.
An estimated 1 billion people do not have access to clean drinking water, a problem expected to worsen with climate change, according to the World Health Organization. In addition, higher energy needs and increased use of heavy metals in industrial processes have increased human exposure to these toxic materials from drinking water in recent decades. Researchers now report in ACS Central Science a new material that can remove heavy metals and provide clean drinking water in seconds.
Since the Flint Water Crisis in Michigan, concern in the US over lead in drinking water has increased. Information about water from private wells has been limited because such wells are exempt from the 1974 Safe Drinking Water Act, the 1986 Lead Ban and the 2011 Reduction of Lead in Drinking Water Act. Now, researchers report a case study in ACS' journal Environmental Science & Technology that sheds some light on the hidden health risks.
'Has this patient been drinking?' It's a critical question for neurosurgical nurses and other professionals when evaluating patients with traumatic brain injury (TBI). But some groups of TBI patients are less likely to be screened for alcohol use, including women and younger patients, reports a study in the March issue of the Journal of Neuroscience Nursing, official journal of the American Association of Neuroscience Nurses.
Researchers monitoring San Francisco Bay for algal toxins have found a surprising array of different toxins in the water and in mussels collected from the bay. Four different classes of toxins, including one produced in freshwater environments, occur regularly throughout the bay, according to a study led by UC Santa Cruz researchers.
This is the first comprehensive review of gaps in risk assessments for adjuvants in pesticide formulations which are not currently subject to safety assessments. Ignoring the potential dangers of other ingredients in commonly used commercial pesticides leads to inaccuracies in the safety profile of the pesticide solution, as well as confusion in scientific literature on pesticide effects. The review suggests that new regulations are needed to protect people and the environment from toxic pesticide ingredients.
Many households can claim at least one four-legged friend as part of the family. But pets that primarily stay indoors can have increased rates of diseases, such as diabetes, kidney diseases and hypothyroidism compared with those that stay exclusively outside. Some scientists propose that chemical substances in the home could contribute to these illnesses. One group has examined how pets could be exposed to parabens, as reported in ACS' journal Environmental Science & Technology.
A new special publication orchestrated by five of the nation's leading hearing experts compiles the latest research into hearing loss caused by drugs and solvents -- how it occurs, how to treat it, and how to prevent it. The compilation is being published online as a special research topic by the journal Frontiers in Cellular Neuroscience.
