EWG Health Guideline 150 ppb

The EWG Health Guideline of 150 ppb for toluene was defined by the California Office of Environmental Health Hazard Assessment as a public health goal, the level of a drinking water contaminant that does not pose a significant health risk. This health guideline protects against harm to internal organs.

EPA Maximum Contaminant
Level (MCL) 1,000 ppb

The legal limit for toluene, established in 1991, was based on a toxicity study in laboratory animals conducted in the 1980s.

ppb = parts per billion
