A tort is a wrongful act (other than a breach of a contract) that creates civil legal liability for money damages—and in some situations entitles the injured party to injunctive relief—an injunction or court order for the person or entity committing the wrongful act to stop a certain behavior or action. A person who commits a tort is known as a tortfeasor.

A toxic tort is a tort that involves exposure to harmful pharmaceuticals, chemicals, solvents, substances, gases, mold, or other materials, causing personal injuries and requiring medical treatment. Examples of toxic tort claims include exposure to asbestos-containing products, pesticides, lead-based paint, tobacco, and hazardous waste materials (such as those used by dry cleaners).

Toxic torts are often associated with personal injury claims, as many toxic torts can cause personal injuries. These claims and the related law are sometimes broadly referred to as toxic tort law.

In Maine, a tort is recognized as a civil wrong that can result in the tortfeasor (the person who commits the tort) being held liable for damages. Toxic torts, a subset of tort law, deal with injuries caused by exposure to hazardous substances such as chemicals, pharmaceuticals, and environmental pollutants. Victims of toxic torts in Maine can seek compensation for their injuries through personal injury claims. These claims may cover medical expenses, lost wages, pain and suffering, and other damages. Maine's statutes and case law govern the specifics of toxic tort claims, including the statute of limitations for filing a claim, the standard of proof required, and the types of damages that may be awarded. Additionally, federal laws and regulations, such as those enforced by the Environmental Protection Agency (EPA), may also apply to toxic tort cases, particularly when they involve exposure to substances that are regulated at the federal level.
