Because lead is a heavy metal, it doesn't stay in the air very long. Air monitoring could be helpful in figuring out where the lead from an industry has landed, but there are three problems:
Air monitors are not always turned on.
Air monitors might be looking the wrong way.
Air monitors may not be calibrated to detect lead.
On February 21, 2023 the I. Schumann Company blew up when a kiln used to heat metals (mostly copper and brass) broke spreading molten metal around the shop floor. One side of the building blew out spreading metal, dust, and bricks around the surrounded community and sending a smoke plume high into the sky. The air monitors operated by the city of Cleveland were not turned on until the next day, so there's no record of what was emitted in the smoke and where it might have fallen. CLASH volunteers were on the scene the next day. Bricks from the factory wall were scattered along Alexander Road. They were tested and found to have over 4000 parts per million of lead (ten times the EPA standard) burned on to the surface of the bricks. CLASH volunteers took soil samples from the surrounding area and got reports of lead in excess of EPA standards. High levels were also found by a stream running behind the plant into a culvert that fed Tinker's Creek. Elevated levels were also found in soil adjacent to the horse pasture next to Thistledown Raceway.

Another example of an industrial explosion where lead bullets were stored when the factory River Recycling factory on Bradley Road in the Flats caught fire last year, CLASH suspects lead particles were spread in the smoke from that fire. The PD reported: "That popping sound was of bullets exploding, Norman said. A propane tank attached to a forklift also exploded. One of the things the company recycles is metal casings from bullets, owner Bill Grodin told cleveland.com and the Plain Dealer. Sometimes a gun range will collect spent bullet casings and a live round accidentally makes its way into the recycled material, he said." We're glad that no one was shot, but where did that lead go? Cleveland Health Department reports that they had no records from the fire during the 3 days of burning because the wind was blowing away from the Air Monitor. A local newsite, VDOMA reports "he Cleveland city government has so far refrained from making official statements, but sources within the administration hinted at possible investigations into the plant’s compliance with safety regulations. Meanwhile, the community demands answers. 'If there’s so much propane there, why weren’t we warned earlier?' exclaimed Maria Gonzalez, leader of the local community group. Her words reflect the broader dissatisfaction growing in the city, where industrial facilities are often located close to residential neighborhoods." Ironically just three weeks earlier when 40 shots were fired at a night club on the other end of the Flats, the Mayor had that site closed indefinitely.
Feb. 17, 2026. WTVG) - Delta council approves updated contract for lead contamination from Bunting Bearings demolition "The Village of Delta Council approved emergency action to address lead contamination issues from the Bunting Bearings building demolition, months after air testing found elevated lead levels from demolition dust. [.....] 'The money that’s being used is all grant money, none of it was taxpayer money, so once everything’s done it’s grant money that was used to make the improvement on the land and get it taken care of and cleaned up,' said Mayor Allen Naiber. The Ohio Brownfield Funding is contributing just over $2.4 million to the project. The Village of Delta is putting up $240,000, and Bunting is contributing $229,724. The emergency action comes after the Ohio EPA implemented new rules for future demolitions. The new requirements include sampling, dust suppression and community engagement before buildings can be demolished. Any new demolition plan must also be submitted to the state EPA for approval. 'So we don’t have future issues with any kind of lead, I know that citizens were concerned with that before so we just want to make sure going forward we don’t have those issues,' Naiber said."
Feb. 16, 2026. WTVG Delta council considers new demolition contract after lead dust concerns. "The Delta Village Council is considering a new ordinance to change the contract for the demolition of the Bunting Bearings building. This comes months after air testing found elevated levels of lead from the dust of that factory. Crews started to demolish the Bunting Bearings plant in November of last year. However, the dust from that demolition caused lead to fill the air. For the past month, people living in the area had to be tested for lead exposure. So far, the county health department says blood tests show little to no lead exposure. But now, the council wants to change the contract with advanced excavating and demolition."

March 12, 2026. Canton Repository Study rates health risks related to closed Canton Republic Steel site "The Ohio Department of Health has completed a study of the former Republic Steel site, finding that children living nearby may have faced lead exposure risks before the facility closed in 2023. The department recommends preventive steps for residents, including blood lead testing for children and measures to reduce lead exposure at home. Community members with health concerns are encouraged to contact health providers, according to a Canton City Public Health press release. The city requested the state to investigate possible health risks at the former Republic Steel facility at 2633 Eighth St. NE in 2021. The study found that times of moderate air pollution during the plant's operation may have posed health concerns for highly sensitive individuals. However, the Ohio Department of Health said people living near the site are not likely to face increased risks of cancer or other health problems from metals detected through air testing."

But for decades, the Republic Steel mill on Eighth Street NE compromised outdoor plans for him and his neighbors. Air pollution kicked up by leaded steel production settled on everything in the area — houses, cars and, according to those living nearby, their lungs. 'A lot of people moved here before the smog under the impression it was going to be a quiet, peaceful, safe community,' Thompkins said. 'Some people have told me that had they known what the Republic situation would become, they wouldn't have moved out here.' "
