The permissible exposure limit for ortho-toluidine is 5 parts per million in air, a threshold based on research conducted in the 1940s and '50s without any consideration of the chemical's ability ...

The Goodyear Chemical Plant in Niagara Falls, New York, has been sending the carcinogenic chemical ortho-toluidine into the air at much higher amounts than what the state deems acceptable.

Ortho-toluidine is a known human carcinogen that was linked to bladder cancer in animal experiments as far back as the 1950s. DPA is a possible carcinogen that may damage the bladder, kidneys and ...

If the DEC accepts Goodyear's plan, the company could take interim steps to curb the amount of ortho-toluidine it emits as soon as this spring, with permanent measures to be installed by late 2026.

The New York State Department of Environmental Conservation is requiring Goodyear to resubmit its air permit application for its Niagara Falls facility.

Members at the meeting said in 2023 that Goodyear reported it released over 1,200 pounds of ortho-toluidine on nearly 4,000 residents within two. The DEC’s recommended limit would be 100 pounds.

Nailax is made using a chemical called ortho-toluidine, or OT, for short. When making Nailax, a chemical called diphenylamine, or DPA, is created in the process. OT is a known carcinogen.

The Niagara Falls plant, which has used ortho-toluidine since 1957 to make an additive that keeps tires from cracking and generates DPA as a byproduct, is the site of one of the nation’s worst ...

"The DEC has updated its ambient air guidelines for ortho-toluidine going forward, and Goodyear is working closely with the agency to identify and implement any changes needed based on those new ...

They concluded that exposure to ortho-toluidine was the likely cause. At least 78 Goodyear workers have developed bladder cancer since the mid-1980s. This story is funded by readers like you.

DEC modeling shows the plant is releasing Ortho-Toluidine, a chemical that studies have shown contributes to bladder cancer, at a rate of up to seven times higher than allowed under state guidelines.
