4、id Miriam Aschkenasy, an environmental health expert working with Oxfam America in the region.Much of the contamination rests in the brown, filmy sediment( 沉淀物 ) left behind by Katrinas polluted floodwaters.Recent EPA tests of the sediment confirmed high levels of E. coli bacteria, oil and gas chemi

5、cals, and lead, as well as varying quantities of arsenic.The health risks posed by the sediment are immediate, experts say, because the sludge (淤泥) is nearly impossible for returning residents to avoid. In New Orleans, it covers every surface that was flooded, from cars and now-dead lawns to the ent

6、ire contents of flooded homes, stores, hospitals, and schools.“When people come back, they are exposed to the sediment,“ said Wilma Subra, a chemist from New Iberia, Louisiana, who is analyzing the sediment. “Its in their yards and houses.“Old Pollution ResurfacingPlaquemines Parish, a rural county

7、on the peninsula south of New Orleans, is now covered with even more toxic sediment than it was two weeks ago, thanks to Hurricane Rit a.“Six inches up to one foot ( 15 to 30 centimeters ) of sludge,“ Subra reported.Much of the sludge in Plaquemines is the product of nearby bayous and bay bottoms, w

8、here, sediment was lifted up by Katrinas and Ritas storm surges.The sediment has been polluted over the years with industrial chemicals and heavy metals, said Suhra, who tested the sediment for the Southern Mutual Help Association, a nonprofit organization in New Iberia, Louisiana.“These water bodie

9、s have received industrial wastes for decades,“ she said. “This material has toxic chemicals, metals, and organic petrochemicals ( 石化产品 ).“Matters have only been made worse by multiple oil spills caused by Katrina and Rita.

11、,“ he explained. “Between the animal waste and the human waste, youve got a lot of bacteria.“Protection KitsHealth and environmental agencies are advising people to avoid contact with the sludge. They recommend that people wear gloves, goggles, and dust masks, and that they wash promptly if exposure

12、 occurs.EPA officials are directing people to its Web site (www.epa.gov) to inform themselves of the contamination risks.But most people returning to the area dont have computers to get that information, said Erik Olson, an attorney for the Natural Resources Defense Council, an environmental advocac

13、y group.“If you do read the Web site,“ he added, “you practically have to have a degree in chemistry to understand it.“To better inform people of health risks, the Southern Mutual Help Association and Oxfam America are developing a program to give every returning resident a protective kit.Each kit w

14、ould contain waterproof suits, goggles (风镜), shoe covers, and masks, along with information about potential hazards. Volunteers would give out the kits at the security checkpoints that now stand at the major entrances to affected cities.The groups have made a hundred demonstration kits, which cost a

16、looded homes. “The mold is growing everywhere-homes are just coated with it,“ Subra said.The problem has become so widespread that federal health officials warned Wednesday of allergic reactions and toxic responses to the mold. Professionals should be hired to clean mold that covers more than ten sq

17、uare feet (one square meter), they urged.“Those surfaces that cant be cleaned need to be removed,“ said Steven Redd, chief of the Air Pollution and Respiratory Health Branch of the U.S. Centers for Disease Control and Prevention (CDC).The effects of the mold are already surfacing in Mississippi, whe

18、re respiratory ( 呼吸的 ) problems are among the illnesses doctors there are reporting.“Were seeing a lot of asthma from inhaling the mold,“ said Richard Paat, team leader of a temporary East Biloxi clinic.“And month sores from the bad water.“Due to contact with unclean water, 33 people in the flood zo

19、ne have contracted Vibrio infections, according to the CDC. The infections are caused by a family of bacteria that live in contaminated salt water. They can cause serious illness, especially in people with compromised immune systems.To date, six people have died from Vibrio infections.“People had op

21、s in Louisiana and Alabama.Her teams have been inoculating residents for tetanus and Hepatitis A andB. Hepatitis is a danger when people are exposed to sewage, through water or food, Briggs explained. Tetanus can occur when people cut themselves on unclean materials, as may happen when cleaning debr

22、is.The rudimentary (根本的) living conditions in many Katrina-struck areas make it more likely that people will get sick and injured, Briggs said.“They have no electricity, no clean water, no air conditioning,“ she said. “There are collapsed structures and stray animals. There are huge amounts of stray

23、 dogs, and people have been bitten.“Briggs and other doctors in the area have been treating many cases of diarrhea, rashes, and upper-respiratory illnesses.All of these conditions are to be expected after natural disasters, according to the CDC. But its too soon to know if these ailments are related
