Health Hazards

The final years of the U.S. housing boom and a disastrous series of Gulf Coast hurricanes created a golden opportunity for Chinese drywall manufacturers. With domestic suppliers unable to keep up with demand, imports of Chinese drywall to the U.S. jumped 17-fold in 2006 from the year before. That imported drywall is now at the center of complaints of foul odors seeping from walls.

People have been asking for years whether cellphones can give you a brain tumor. And for years, the wireless industry has been telling us not to worry our pretty heads. So that's settled, right? Maybe not. A group called the International EMF Collaborative issued a report the other day warning that cellphones may be more dangerous than users have been led to believe by health authorities. The report, titled "Cellphones and Brain Tumors: 15 Reasons for Concern," says the latest research indicates that regular use of cellphones can result in a "significant" risk of brain tumors.

Eating red meat increases the chances of dying prematurely, according to a large federal study offering powerful new evidence that a diet that regularly includes steaks, burgers and pork chops is hazardous to your health. The study of more than 500,000 middle-age and elderly Americans found that those who consumed the equivalent of about a small hamburger every day were more than 30% more likely to die during the 10 years they were followed, mostly from heart disease and cancer.

Emily McCarthy thought the foul smell in her new Florida town house was coming from Samson, the family dog. McCarthy and her husband gave the English Springer bath after bath. But the stink wouldn't go away. And that wasn't all. Electrical outlets turned black. The air conditioner went on the blink. Then McCarthy, 33, started waking up with a bloody nose. It turns out the home was built with imported Chinese drywall.

Air quality has improved to "good" and "moderate" levels in Los Angeles County after clouds of smoke from the nearly three-week Station fire prompted health officials to caution residents and warn against strenuous outdoor activities. The South Coast Air Quality Management District has not issued a smoke advisory since Thursday and has since reported that most unhealthy air in the Los Angeles Basin is not attributed to the fire, said spokesman Sam Atwood. "There is a small possibility where there could be some unhealthy air quality in areas that are directly impacted by smoke, but we just haven't seen that occurring in the San Gabriel or San Fernando valleys the last couple of days," Atwood said.

The call center job came with a good salary and good perks, especially compared to many other opportunities for young people in India. But as 26-year-old Vaibhav Vats says, it was doing him no good. His weight grew to 265 pounds and long overnight hours gave him little time for a social life. Eventually, he quit. "You are making nice money. But the trade-off is also big," said Vats, who spent nearly two years at an IBM Corp. call center handling customer calls from the United States.

Smoking a cigarette in a car makes the air inside 10 to 30 times more toxic than the air outdoors on one of Southern California's most polluted days. On Thursday, state officials put on a live demonstration of that health hazard to promote a new law that bans smoking in cars carrying minors. Neil Klepeis, a Stanford University environmental health scientist, attached sensors to the dashboard of a 1999 Toyota Corolla parked on the lot of the Hollywood United Methodist Church.

A controversial, estrogen-like chemical in plastic could be harming the development of children's brains and reproductive organs, a federal health agency concluded in a report released Tuesday. The National Toxicology Program, part of the National Institutes of Health, concluded that there was "some concern" that fetuses, babies and children were in danger because bisphenol A, or BPA, harmed animals at low levels found in nearly all human bodies.

The next time you make some microwave popcorn or cook a frozen pizza, consider this: The packaging of many of these products contains a chemical that the Environmental Protection Agency considers potentially carcinogenic and wants businesses to voluntarily stop using by 2015. Studies show that this chemical -- perfluorooctanoic acid, or PFOA -- is present in 98% of Americans' blood and 100% of newborns. It doesn't break down and thus accumulates in the system over time.

With patients facing increasing threats from antibiotic-resistant "super bugs," Gov. Arnold Schwarzenegger on Thursday signed two measures requiring California hospitals to strengthen their efforts at preventing staph outbreaks and to reveal to the public their rates of infection. The move was a reversal for the governor, who vetoed similar legislation four years ago.
