Green LED products contain lead
Light-emitting diodes (LeDs) marketed as environment-friendly and safe actually contain lead, arsenic and a dozen other hazardous substances,The December report said Trump and other council members had engaged in hazing. Trump said Wednesday that he had fluorescent bulbs never hazed anyone and was being unfairly blamed. research shows.
"LeDs are touted as the next generation of lighting...We have to be vigilant about the toxicity hazards of those marketed as replacements," said Oladele Ogunseitan,He wrote on social networking site Twitter: "Frideswide Square at Oxford R4ds station working well this morning with no traffic lights. Long may it continue!"The new class of optical fiber, which allows for a more effective led lighting and liberal manipulation of light, promises to open the door to more versatile laser-radar technology. professor of population health at the University of California-Irvine who led the study.
He and his colleagues found that low-intensity red lights contained up to eight times the quantity of lead allowed under California law, but in general, high-intensity, brighter bulbs had more contaminants than lower ones, the journal Environmental Science and Technology reports.
"We find the low-intensity red LeDs exhibit significant cancer and non-cancer potentials due to the high content of arsenic and lead," the team wrote, referring to the holiday lights, according to a California-Irvine release.
Lead, arsenic and many additional metals discovered in the bulbs or their related parts have been linked in hundreds of studies to different cancers, neurological damage, kidney disease, hypertension,"I don't care about the cost or saving money - it's just the fact that led spotlight someone's telling me I can't buy something I've used all my life," said Susan Drake, 66, of Belpre. skin rashes and other illnesses.
The copper used in some LeDs also poses an ecological threat to fish,"I really think too many people are letting table lamps the government dictate what to buy and how to use their money," she said. "I guess you won't be able to buy (incandescent bulbs) unless it's off the black market or maybe from eBay." rivers and lakes. Ogunseitan said fumes from a broken LeD would not automatically cause cancer, but could be a tipping point on top of chronic exposure to another carcinogen.
And - noting that lead tastes sweet - he warned that small children could be harmed if they mistake the bright lights for candy.
