At first, teachers at Sky Valley Education Center simply evacuated students and used fans to clear the air when the fluorescent lights caught fire or smoked with noxious fumes. When black oil dripped onto desks and floors, they caught leaks with a bucket and duct-taped oil-stained carpets.Then came the tests that confirmed their suspicions about the light ballasts.“Sure enough ... it was PCB oil,” said Cynthia Yost, who was among teachers who sent pieces of carpet and classroom air filters to a lab. Tests found elevated levels of the toxic chemicals, used as coolant in the decades-old ballasts that regulated electrical current to the lamps.Millions of fluorescent light ballasts containing PCBs probably remain in schools and day care centers across the U.S. four decades after the chemicals were banned over concerns that they could cause cancer and other illnesses. Many older buildings also have caulk, ceiling tiles, floor adhesives and paint made with PCBs, which sometimes have been found at levels far higher than allowed by law.Yet the Environmental Protection Agency has not attempted to determine the scope of PCB contamination or assess potential health risks, in large part because of lack of funding, political pressure and pushback from industry and education groups, according to dozens of interviews and thousands of pages of documents examined by The Associated Press.Members of Congress who promised three years ago to find money to help address PCBs and other environmental problems in the nation’s schools never introduced legislation.And an EPA rule that would have required schools and day cares to remove PCB-containing ballasts moved slowly under the Obama administration, then was quashed by President Donald Trump within days of his inauguration.That was the final straw for Tom Simons, a former EPA regulator who worked for years on the rule and said getting rid of ballasts was the least the EPA could do to protect children.“We thought it was a no-brainer: There are millions out there. These things are smoking and dripping, so let’s put this through,” said Simons, who retired shortly after Trump took office.___For decades, the presence of PCBs in schools flew under the radar.States, cities and environmental agencies focused on removing them from lakes, rivers and toxic waste sites because most exposure to PCBs is believed to come from people’s diet, including fish from contaminated waterways, and because PCBs do not break down easily. Studies have linked them to increased long-term risk of cancer, immune and reproductive system impairment and learning problems.PCBs, or polychlorinated biphenyls, are mixtures of compounds manufactured by Monsanto Co. and widely used as coolants and lubricants in electrical equipment until they were banned in 1979.By then they were in transformers, air conditioners, adhesives, carbonless copy paper and billions of fluorescent light ballasts in schools, hospitals, homes, offices and commercial and industrial buildings. They also were ubiquitous in the environment and building up in human bodies.Nobody worried about schools.Then a 2004 study by Harvard health professor Robert Herrick identified the widespread use of PCBs as a plasticizer in caulk in schools built before 1980, estimating that as many as 14 million students and 26,000 schools could be affected. The EPA had not been aware of its use in caulk before then, Simons said.The EPA later found that the chemicals can move from building materials into the air and dust, where they can be inhaled or ingested. They also can be absorbed by walls and other surfaces as an ongoing source of exposure.Regulators also discovered that old fluorescent light ballasts remained a potentially widespread source of PCB contamination. The EPA had allowed the ballasts to remain in use because chemicals were in enclosed capacitors that experts thought would last only about 12 years. But it turns out they can last a half century or longer, said Simons.The older they are, the more likely ballasts will leak, catch fire or smoke. And that has happened repeatedly in schools, office buildings, restaurants and factories in recent years, according to reports reviewed by the AP.But the EPA has mostly voluntary guidelines, including recommended indoor air limits for PCBs that it says should protect children from health problems.The agency does not require — or encourage — schools to test for PCBs, so few do. If they are found in materials such as caulk, schools could be forced to undertake expensive cleanups when many are struggling to keep basic infrastructure intact and meet educational needs. Drawing attention to the issue also risks alarming parents.PCBs are illegal in building materials in concentrations exceeding 50 parts per million — a threshold set by the EPA decades ago based on how much contaminated material could affordably be removed rather than health risks.Rather than fostering “a very confusing and fearful situation,” the EPA should recommend that schools test classroom air for PCBs, then identify and address specific sources if the results are elevated, said Keri Hornbuckle, a civil and environmental engineering professor at the University of Iowa and one of the nation’s top researchers of PCBs in schools.“There is a good reason PCBs were banned, so ... let’s remove the worst cases and where (kids) are most vulnerable and have the highest exposure,” she said. “But you have to have the data.”Whether PCBs are addressed often is determined by ZIP code.In California’s wealthy Santa Monica-Malibu School District, parents, including model Cindy Crawford, sued to force the district to address PCBs after tests of caulk found levels up to 11,000 times the 50 ppm threshold. The district ultimately agreed to get rid of PCBs. It has torn down a middle school and continues to remove them from other buildings.In Hartford, Connecticut, the ending was far different. John C. Clark Elementary and Middle School, in a largely low-income African American neighborhood, was permanently closed in 2015 after PCBs were found and the city could not afford to remove them. The city has sued Monsanto and a company that manufactured caulk to recover the costs.“It was the crown jewel of the neighborhood,” Steven Harris, a former city council member and grandfather, said as he walked the deserted school grounds. “Our school board is doing the best they can. The reality is we don’t have a lot of money. And it’s going to take money to fix this problem.”Monsanto, now owned by Bayer Crop Sciences, has denied responsibility in lawsuits involving several school districts, saying it did not manufacture the building materials or components that contained PCBs.Concerns over schools like Hartford’s are one of the issues that ultimately kept the EPA from taking stronger steps to address PCBs.The agency, which originally recommended that schools test for the chemicals, was warned by the Association of California School Administrators that forcing schools to remove PCBs could create “a civil rights issue” if low-income minority schools could not afford it. What’s more, many of those schools have other environmental problems — including lead, asbestos and mold — that could be higher priorities.So instead, the EPA developed guidance that promotes vigilant cleaning and better ventilation and suggests schools could cover materials suspected of containing PCBs until the buildings are renovated or razed.But the recommendations were released quietly on the agency website to avoid publicity that might frighten the public, according to former EPA officials who said the agency was hamstrung by a problem that could cost billions of dollars. There are no rules requiring school officials to tell parents if they find or suspect their buildings have PCBs.Judith Enck, administrator of the EPA’s Region 2 under Obama, said the EPA bowed to intense political pressure.“The debate was never based on science and health. It was ‘We don’t want the grief from schools, and it’s a lot of work and we have other priorities,’” said Enck, who led an effort to get ballasts out of New York City schools. “I disagreed.”A bill introduced in 2010 by three New York congressmen aimed at funding school PCB cleanups was withdrawn after New York City officials agreed to replace aging ballasts. Sen. Ed Markey of Massachusetts released 8392

As cyclones and droughts are expected to grow in frequency and intensity while global temperatures rise, humankind's closest relatives will become increasingly vulnerable to extinction, scientists say.At climate change's current pace, nearly 40% of the Earth's primates will be threatened by the extreme weather events that accompany rising temperatures, a new study says. And with 60% of primate species already vulnerable to habitat loss and human activity, researchers are pleading that conservationists consider both human and climatic impacts in their efforts.In the study, published in the journal 616

Bernie Sanders has scored a resounding victory in Nevada’s presidential caucuses. His win on Saturday cements his status as the Democrats' national front-runner, though it's also escalating tensions over whether he’s too liberal to defeat President Donald Trump. The 78-year-old Vermont senator successfully rallied his loyal base and tapped into support from Nevada’s large Latino community as the Democratic contest moved for the first time into a state with a significant minority population. Sen. Sanders is celebrating his Nevada caucus victory hundreds of miles away in Texas.The Vermont senator took the stage before thousands of cheering supporters inside the Cowboys Dance Hall in San Antonio on Saturday night and declared, “We’re going to win this election.” The country’s second largest state votes on “Super Tuesday” on March 3, after next week’s South Carolina primary, but Sanders wasted little time declaring, “We are going to win here in Texas.”He added: “We are going to win across the country because the American people are sick and tired of a president who lies all of the time.”Sanders then modified the standard campaign speech he gives multiple times a day to touch more heavily on immigration for an audience about 150 miles from the U.S.-Mexico border. He noted that his father immigrated to the U.S. from Poland "without a nickel in his pocket" and added, "I know something about the immigrant experience. Together we are going to end the demonization” of immigrants.Amy Klobuchar is telling supporters her presidential campaign has “exceeded expectations” and she plans to carry on, even as she trailed far behind several rivals in Saturday’s Nevada caucuses.The Minnesota senator returned to her home state Saturday following a morning event in Las Vegas. Speaking to volunteers Klobuchar said that "a lot of people didn’t even think I would still be standing at this point."Klobuchar finished in fifth place in the kickoff Iowa caucuses before a strong debate performance helped lift her to third place in New Hampshire. She will campaign Sunday in Fargo, North Dakota, before holding events in Arkansas and Oklahoma, both states that will vote in the March 3 “Super Tuesday” contests. On Monday she will be in South Carolina, which holds its primary Saturday and where she will participate in a Tuesday debate.Meanwhile, Joe Biden is declaring himself back into the race for the presidency after early results in Nevada showed the former vice president in second place. Biden told supporters Saturday that “we're alive and we're coming back and we're gonna win.” Biden thanked unions for their support, citing labor groups that have endorsed him including firefighters, ironworkers and electrical workers.He took a shot at the race's frontrunner, self-declared democratic socialist Bernie Sanders, and former New York Mayor Mike Bloomberg, who isn't competing in the first four states but has spent hundreds of millions of dollars of his own fortune hoping to pick up delegates starting on Super Tuesday."I ain't a socialist. I ain't a plutocrat," Biden said. "I'm a Democrat. And I'm proud of it."Biden said the Russians will continue to support President Donald Trump and Sanders, whose campaign acknowledged Friday that he was briefed last month by U.S. officials about Russian efforts to boost his candidacy."Let's give Trump exactly what he doesn’t want," Biden told his supporters. “Let's give him you and Joe Biden as the nominee.” 3481
