4、with the latest crisis in the region: contamination(污染 ). Katrina left New Orleans and other communities tainted with oil, sewage, and possibly poisons leached from federal toxic waste sites, the U.S. Environmental Protection Agency (EPA) says. The pollution, combined with the lack of regular medica

5、l services in the region, has raised serious questions about the safety of New Orleans and other coastal towns as people longing for home begin to go back. “I dont think New Orleans is safe for people to return to, from a public health and environmental health standpoint,“ said Miriam Aschkenasy, an

6、 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 chemicals, and lead, as well

7、 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 entire contents of flood

8、ed 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 Resurfacing Plaquemines Parish, a rural county on the peninsula s

9、outh of New Orleans, is now covered with even more toxic sediment than it was two weeks ago, thanks to Hurricane Rita. “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, where sediment was l

10、ifted up by Katrinas and Ritas storm surges. The sediment has been polluted over the years with industrial chemicals and heavy metals, said Subra, who tested the sediment for the Southern Mutual Help Association, a nonprofit organization in New Iberia, Louisiana. “These water bodies have received in

11、dustrial 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. According to the U.S. Coast Guard, 11 oil spills have occurred in southern Louisiana, totaling

12、7.4 million gallons (28 million liters) of oil, most of which has been contained. Bacteria levels are also especially high in the Plaquemines sludge, said Rodney Mallett, spokesperson for the Louisiana Department of Environmental Quality. “The sewage treatment plants were underwater,“ he explained.

13、“Between the animal waste and the human waste, youve got a lot of bacteria.“ Protection Kits Health 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 occurs. EPA of

14、ficials 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 advocacy group. “If

15、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 would conta

16、in 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 about $10

17、0 (U.S.) each to produce, and have shown them to state leaders in Louisiana. “The governor is really in favor of this,“ Subra said. “We just have to determine how were going to fund them.“ Toxic Mold Blooms In addition to the toxic sediment, sprawling blooms of mold have now taken hold in many flood

18、ed 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 tan squar

19、e 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, wher

20、e 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 mouth sores from the bad water.“ Due to contact with unclean water, 33 people in the flood z

21、one 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

22、 open wounds and walked through floodwater with sewage in it,“ CDC spokesperson Von Roebuck said. “And these folks were having these wounds infected with Vibrio.“ Disaster Response Care “This is a highly contaminated area,“ said Susan Briggs, the physician overseeing FEMAs disaster-response medical

23、teams in Louisiana and Alabama. Her teams have been inoculating residents for tetanus and Hepatitis A and B. 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 cleanin

24、g debris. 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

25、 of stray 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

26、are related to contamination, the CDCs Roebuck said. “Were looking at that question,“ he said. “Wed like to know the answer.“ 2 The passage gives a description of the contamination in New Orleans after Hurricane Katrina. （ A） Y （ B） N （ C） NG 3 Katrina left New Orleans and other communities tainted
