Petrochemical thinners like turpentine are volatile organic compounds that can cause respiratory, neurological, and developmental harm through inhalation or ingestion. Acute exposure can cause dizziness or death, while chronic exposure is linked to cancers and impaired brain function. The document outlines case studies of accidental thinner ingestion and provides first aid instructions. It also proposes citrus solvent as a safer alternative for its biodegradability and lack of toxicity.
