A toxic tort is a legal claim for harm caused by exposure to a dangerous substance, such as chemicals, asbestos, mold, contaminated water, pesticides, or industrial fumes.

These cases usually come up when someone gets sick, develops an occupational disease, or suffers long-term health problems after contact with a harmful product or polluted place. A worker breathing dust on a jobsite, a tenant exposed to lead paint, or a family dealing with contaminated drinking water may all have a toxic tort claim. Unlike a simple accident case, these claims often turn on proving exposure, showing the substance can cause the illness, and linking that exposure to the person's actual medical condition. That usually means gathering medical records, work history, testing results, and sometimes expert opinions on causation.

For an injury claim, timing and paperwork can make or break the case. In New York, CPLR 214-c allows the statute of limitations in many toxic exposure cases to run from the date the injury was discovered, or reasonably should have been discovered, rather than the date of first exposure. That matters because illnesses from chemicals or asbestos may not show up for years. If the exposure happened at work, there may also be a workers' compensation claim, but that does not always block a separate case against a manufacturer, landlord, or outside contractor. Save test results, incident reports, and names of witnesses early.
