Based on the current knowledge on the effects of several gases and vapors, some of these appear to be more harmful to human health than initially thought. In such cases, the Dutch health council reviews the current limit values and lowers these if deemed necessary.

Benzene is categorized as a carcinogenic gas and is very harmful to human health. The current limit value of benzene is 3.25 mg / m3 (1 ppm). After assessment by the Health Council, it’s decided to reduce this limit (in the Netherlands) by October 1st 2017 to 0.7 mg / m3 (0.2 ppm).
