New California rules aimed at curbing the surprising amount of pollution coming from leaf blowers, lawn mowers and other small gas-powered machines cleared a final hurdle Monday, and are set to take effect on Jan. 1.
The requirements mark another step in the state’s long-running battle to reduce emissions from a category of small engines that have come to rival cars as a source of smog-forming pollution.
OSHA has cited Anderson Foot and Ankle Clinic for potentially exposing employees to infectious materials, and for violations of the hazard communication standard. The agency proposed penalties totaling $93,074. OSHA inspectors cited the Rolla-based podiatry clinic for improperly handling medical waste, failing to review the exposure control plan annually, and failing to provide vaccines for employees exposed to bloodborne pathogens. The clinic also was cited for failing to update safety data sheets, and for lacking a list of hazardous chemicals used in the workplace.
A new mining safety standard, a failed effort in one state to slow the opioid epidemic and an increased role for 911 dispatchers in saving lives. These were among the top stories featured on ISHN.com this week. A NIOSH Science Blog post: To Beard or not to beard? That’s a good question!
The month of November is full of fun, interesting, and thought-provoking observances. November is National Raisin Bread Month, Historic Bridge Awareness Month, and Inspirational Role Models Month among so much more.
The month of November is full of fun, interesting, and thought-provoking observances. November is National Raisin Bread Month, Historic Bridge Awareness Month, and Inspirational Role Models Month among so much more. November is also the host month to campaigns like No-Shave November and Movember. Campaigns such as these are working hard to raise money for important causes such as cancer research, education, and awareness. These increasingly popular campaigns are a great way to demonstrate your support … unless you need to wear a tight-fitting respirator for your job.
New research presented this week at APHA’s 2017 Annual Meeting and Expo examined the burden of air pollution and its association with mortality in Chinese cities. The study by researchers at Drexel University Dornsife School of Public Health showed a significant correlation between higher air quality index concentrations and higher mortality rates. The study is the first to provide strong evidence of the burden of air pollution in major Chinese cities, as well as the impacts of air quality and climate change on urban population mortality.
Daniel Levitin, a cognitive neuroscientist and the author of "This is Your Brain on Music," says listening to music while you work is likely to make you less productive.
"You're having so much more fun," said Levitin, "that you feel more productive."
He cited a growing body of research suggesting that, in almost every case, your performance on intellectual tasks (think reading or writing) suffers considerably when you listen to music.
10. Nursery Worker or Teacher (85 dB)
A class of 30 children can be exceptionally noisy. Nursery workers and teachers suffer the effects of excessive noise — up to 85 dB — which, with continued and prolonged exposure, can cause damage to the eardrum.
A study by Simone Ritter at Radboud University in the Netherlands and Sam Ferguson, at the University of Technology in Sydney, Australia, looked at how listening to various types of music affected different types of thinking compared to working in silence.
Their study found that happy music enhanced participants’ creative “divergent thinking.” However they found it had no impact on “convergent thinking,” which is problem-solving.
The most widespread and well-documented subjective response to noise is annoyance, which may include fear and mild anger, related to a belief that one is being avoidably harmed. Noise is also seen as intrusive into personal privacy, while its meaning for any individual is important in determining whether that person will be annoyed by it.
Evolution did not equip you to live in a world of constant noise. Your nervous system was engineered by natural selection for an environment of almost total quiet. Nature is mostly filled with soft, quiet sounds: leaves rustling, water trickling, insects buzzing. An animal call here and there. This is what your amygdala (the fear center in the brain) rates as a normal sound level. Sharp sounds, loud bangs, people yelling and crying, revving engines and the like all trigger a fear/danger response.
