PARKLAND, Florida (CNN) -- Yorelle Haroush fled a million-dollar South Florida home this week, chased out, she said, by drywall made in China that's emitting vapors that smell like rotten eggs.





Amy Massachi hugs her pregnant niece, Yorelle Haroush, as she prepares to move this week.





"It's making me sick. Physically, mentally and emotionally, making me sick," said the 18-year-old, who is pregnant with her first child.





Haroush lives with her aunt Amy Massachi and her four siblings and cousins in the house. They believe a year's worth of upper respiratory infections, antibiotics, bloody noses and sickness have been caused by the walls.





Their doctor said they need to get out of the $1.2 million estate in Parkland, Florida, northwest of Fort Lauderdale.





"I said, 'you can't stay there anymore, because you're sick every minute,'" the family's longtime physician, Dr. Ross Nochimson, told CNN. "They're sick on a weekly basis. Earaches, sore throat. I give them something, and they're sick again."





Massachi and her family are among homeowners in more than a dozen states who allege Chinese drywall has emitted corrosive gases they believe have given them health problems.





Homeowners also allege the gases corrode metal components including copper wiring, causing air conditioners and other household systems to fail.  Read about homeowners' allegations »





The U.S. Consumer Product Safety Commission says most of the complaints have come from Florida, where the concerns emerged last year. But consumers also have filed complaints in Louisiana, Virginia, Wisconsin, Ohio, Alabama, Mississippi, California, Washington, Wyoming, Arizona, Tennessee and Washington, D.C.





The Florida Department of Health says complaints it received -- more than 330 as of Tuesday -- generally involve homes built between 2004 and 2007.





A study done for the Florida health department by private laboratory Unified Engineering Inc. found that samples of certain Chinese drywall gave off a sulfurous odor from "volatile sulfur compounds" when exposed to extreme heat and moisture. It also found that vapors "in the residential atmosphere created a corrosive environment in the presence of moisture."





The health effects of those vapors are still the subject of several scientific studies.





Odors and corrosion are clearly evident in the Massachi house.





The pungent, rotten-egg-like smell permeates the two-story home. Throughout the house, electrical outlets are open to reveal black corrosion on the copper wiring. The air conditioning unit's air handler, inside the house, is blackened.





"This is disgusting. It's so corroded. I can't even believe it," Amy Massachi said in a raspy voice. "I can't breathe. Every morning, I wake up with sinus allergies, my voice is hoarse.  Watch Massachi explain what's happening in her house »





"My mother, when I call her up on the phone, she says, 'Amy, what's wrong with your voice?' and I say, 'allergies.'  "'What are you allergic to?' I don't know. Well, now I know. I'm allergic to my house. My house is making us sick."





The doctor recommends they vacate their 18-month-old home.





"Before they bought this house, they weren't calling every week with allergies and sore throats and ear aches and coughing," Nochimson said. "I don't know what more I can do for them."





Haroush, who after giving birth faces heart surgery for an unrelated condition, is moving in with her grandmother.





"I'm graduating this year, and I'm having a baby, and I don't need to be thinking about anything else going wrong, and any more stress that is on me," she told CNN.





Chinese drywall was imported into the U.S. during a different economic era, at the height of a housing boom. Prices were sky high, and the country was hit by two active hurricane seasons in 2004 and 2005, increasing the demand for
