Asbestos, lead, radon, indoor air quality, and PCBs

Recognize the hazard and the exposure route

Asbestos, lead, radon, indoor air pollutants, and polychlorinated biphenyls (PCBs) require different responses. A real estate salesperson should recognize warning signs, communicate known information, and refer evaluation and remediation to qualified professionals rather than diagnose conditions or disturb suspect materials.

Asbestos was used in insulation, fireproofing, and some flooring and other building products. The principal concern is inhaling airborne fibers. Friable material crumbles readily under hand pressure when dry; damage or disturbance can release fibers. Intact material may sometimes be managed in place after professional evaluation. Removing it carelessly can increase exposure.

Lead can occur in paint, contaminated dust and soil, and plumbing. Deteriorating paint and renovation dust create exposure risks, especially for young children. Under federal law applicable in New York, covered housing built before 1978 triggers lead disclosure requirements. Before the buyer or tenant becomes contractually obligated, sellers and lessors must provide the lead hazard pamphlet, disclose known lead-based paint and hazards, and provide available lead hazard evaluation reports. Buyers receive a ten-day opportunity for a lead risk assessment or inspection unless the parties mutually agree on a different period. This purchaser opportunity is distinct from disclosures owed to tenants. Purchase contracts require a Lead Warning Statement and purchaser acknowledgments. Agents engaged to sell or lease covered housing must ensure compliance. Disclosure is not a certification that a home is lead-free.

New York's Public Health Law separately establishes lead poisoning prevention, screening, education, and exposure reduction programs. Section 1370 includes accessible lead paint, peeling or chipping paint, and other significant lead exposure conditions in its definition of a condition conducive to lead poisoning. Section 1373 provides for notice and demand to discontinue qualifying paint conditions in designated dwellings in high-risk areas, specifying the corrective method and allowing enforcement. A federal disclosure does not substitute for this public health process.

Radon is a naturally occurring radioactive gas that can enter from soil through foundation openings and accumulate indoors. It has no detectable odor or color; testing establishes its level. Long-term exposure increases lung cancer risk. A common mitigation method draws soil gas from beneath the slab and vents it outdoors.

Indoor air quality reflects pollutant sources, ventilation, and moisture. Combustion gases, volatile organic compounds from products, and mold associated with moisture can impair air quality. Correct the source, address water intrusion, and use appropriate ventilation; fragrance merely masks odors.

PCBs are persistent industrial chemicals associated with some older electrical equipment, including transformers and capacitors, and certain building materials such as caulk. Suspect equipment or materials need specialized evaluation and handling. They are not asbestos fibers or soil-generated radon.

Match the hazard to its source and exposure pathway, then distinguish physical risk management from transaction disclosure requirements.
