Exposure to TCE in humans occurs through which routes?

Exposure to trichloroethylene (TCE) can occur through more than one route: inhaling air containing vapors, ingesting contaminated drinking water, and coming into contact with the chemical on the skin. In occupational settings, workers may be exposed to vapors in the air and through handling liquids, while the general environment can expose people via contaminated air and water. The option that mentions occupational exposures, air, and drinking water best reflects these real-world routes, covering inhalation and ingestion and acknowledging workplace contact. The other options suggest a single route only, which doesn’t capture how TCE exposure happens in practice.
