Amid the usual samples of fish, bugs and river sediment, this month there is an unlikely assortment of wood and metal scraps in David Velinsky's environmental research lab at the Academy of Natural Sciences. Contained in six plastic bags, the scraps came from the wreck of the USS Monitor, the ironclad Civil War battleship that revolutionized naval combat. The vessel deteriorated sharply in the century after it sank in a storm off Cape Hatteras, N.C., in 1862, and ever since the wreck was discovered in 1973, conservationists have labored to slow the aging process.

It was yet another nightmare on I-95. Traffic on the busy highway was stopped in predawn hours today after a tank truck carrying 3,000 gallons of toxic sulfuric acid flipped over and rolled into a ditch. Both northbound and southbound lanes of the interstate between the Academy Road interchange in Northeast Philadelphia and the Street Road interchange in Bensalem Township, Bucks County, were closed after the 4:47 a.m. accident, just before the start of morning rush hour. None of the acid appeared to have leaked from the tractor-trailer tanker, authorities at the scene said.

Several cars of a CSX train carrying sulfuric acid derailed early yesterday, dumping its contents into the Schuylkill River and onto Kelly Drive in the city. The 12 cars on the 39-car train traveling from Canada to Baltimore derailed about 1:30 a.m. Two of the cars leaked about 12,000 gallons of the acid onto the roadway used by many commuters traveling into the city, and the adjacent river. Sulfuric acid is a corrosive chemical used in car batteries. The road was closed for several hours.

The evacuation of more than 200 people and at least 50 businesses, the mobilization of scores of police officers and fire officials, the closing of numerous streets, and the detours of hundreds of drivers - all because of a cigarette butt? Environmental Protection Agency officials found evidence yesterday that a discarded cigarette butt - or possibly a firecracker tossed through a vent on top of an abandoned storage tank in a Bensalem industrial park - sparked a chemical reaction that resulted in hazardous sulfuric acid vapors escaping into the air last month.

A large tank containing recycled sulfuric acid exploded yesterday afternoon in Salem County, rocking Du Pont Co.'s Chambers Works plant in Deepwater, officials said. The tank exploded at 1:36 p.m. at the center of Du Pont's largest chemical plant, said Kelli Kukura, a company spokeswoman. The 30,000-gallon-capacity tank contained about 22,000 gallons of recycled sulfuric acid. The explosion created a thick cloud of smoke, officials said. The ensuing fire was brought under control in half an hour and extinguished by about 3 p.m., officials said.

About 200 people evacuated from an area around a Bensalem industrial park since Wednesday because of sulfuric acid fumes escaping from a storage tank were permitted to return yesterday after the area was declared safe, officials said. The half-mile stretch of State Road, between Street Road and Station Avenue, was reopened at 1 a.m. after the federal Environmental Protection Agency installed a scrubber to neutralize vapors and subsequent tests showed normal air quality, said Bensalem public safety director Frank Friel.

Howard Smith's white lab coat made him a standout among the heavily outfitted firefighters and hazardous-materials workers who strode yesterday outside a gutted chemical factory in Kensington. As television crews trailed after a moon-suited crew from the Environmental Protection Agency, Smith carefully placed another glass laboratory tube back into his canvas sack. Despite the contrast in styles, the lightly clothed chemist and the workers lugging air packs were working on the same problems outside the still-smoking Purolite Co. plant.

A white, wispy vapor of sulfuric acid continued to escape from a rusted chemical storage tank yesterday in an industrial park in Bensalem, forcing an evacuation to continue for the second day. Officials said yesterday that they expected the leak to be contained overnight and business to resume today. Roads to the immediate area remained closed through last night, and 15 people yesterday were asked to leave summer bungalows in the Columbus Country Club on State Road, local fire officials said.

A fire at a metal-processing plant yesterday spewed a huge, chemical-filled cloud that led to the evacuation of about 14,000 people and the declaration of a disaster emergency by Gov. Casey. Officials, fearful that the black plume from the Spencer Metal Processing Co. contained sulfuric acid, evacuated two Luzerne County communities and called on the Pennsylvania National Guard to assist at the scene. There were no serious injuries, and the smoke cloud largely dispersed by late morning, revealing clear blue skies.

Four workers at a laboratory in Gloucester County were burned, one of them seriously, and an additional 20 people were evacuated from the building when a shelf containing several bottles of sulfuric acid collapsed yesterday. Two firefighters who aided in their rescue also were burned, police said. The four were working at Century Laboratories Inc., an environmental testing lab on Grandview Avenue in the Thorofare section of West Deptford Township, when the accident occurred shortly before 9 a.m., police said.
