Clemson rese into effects t By Associated Press CLEMSON ? Researchers at Clemson University are heading to the woods in hopes of finding what effects acid rain and other pollutants have on pine trees. The project is paid for by the Environmental Protection Agency, and Clemson has already received a $750,000 gituii. inc stiiooi cxpctis 10 gei anomer ?juu,wu soon, said Davis McGregor, a forestry professor. Most of the money has been spent building 24 beehivelike chambers on Clemson's experimental forest two miles from campus. In each circular 15-foot-wide chamber, rows of short-leaf pine seedlings have been planted. A special rain machine will mix acid with pure water and funnel the mixture to the chambers. Acid rain is suspected of slowing the growth of and killing trees in several parts of the country and posing a threat to the nation's $38.5 billion forest products industry. Foresty in South Carolina alone is a $3.5 billion ousmess, ana me state s largest casn crop, McUregor said. "A reduction in growth like we've been seeing means a lot of dollars lost from South Carolina," he said. Acid rain is caused when sulfur dioxide and nitrogen oxides in the air mix with rain. In the 1970s, Canadian scientists found high levels of acidity in that country's lakes and linked fish kills to emissions from the United States. Those scientists say the problem is coal-fired plants in the Midwest, where huge smokestacks boost pollution high into the air and away from surrounding communities. The pollution is carried by atmospheric currents and deposited hundreds of miles away in the form of acid rain, scientists say. In the early 1980s, experts in the United States began to notice unexplained reductions in forest growth. The trend was first SDOtted in New York and New FnolanH hut McGregor said a study four years ago showed tree growth ' DONT CHKKEN I PUT. > % APARTM EiVre W J $50.00 Security Deposit "LOOK BEFORE Excellent Roomm ? ^ Flexible Lea i A11 Adult C?r J Choose Your Location Now F A Located at Exit I - 26 (Zoo Exit) A Right on Greystone - Turn left at traffic light I Call 772-6500 \ W/D connections in all townhomes J Pool & Clubhouse Social calendars ANDY WILLIAMS IS WILLING ' STRAIGHT TO THE DECISION 1 AREN'T YOU READY FOR YOU UU HAVE A CHOI CI VOTE AND^i A FORMAL AN: ^ i 1 ; We Jtiave moved Help us celebr; a 10% Disc Tuxedo Rental ai offer ends I* F>p\/inp i?VAV W V.

He said whole stands of spruce trees are dying in the North Carolina mountains, "and no one knows why." McGregor said he's seen patches of vegetation on the Blue Ridge Parkway that look like they were doused with a herbicide. "They, of course, don't use herbicides up there, so it's hard to believe that it's caused by anything else than air pollution," he said. Some experts think changes in the climate are affecting the forests. Others blame insects and disease. "The problem is we're really not sure what's happening, and we need to find out," McGregor said. "EPA's ultimate purpose is to determine the effects of acid rain and find out at what levels pollution limits should be set," he said. It EXCUSES DONT SAVE UVES. /* ? BLOOD DOES ??
