ANSES has recently issued its assessment of the human health effects of D4 in the workplace. Reproductive toxicity (specifically reduced implantation sites in rats exposed by inhalation) was selected as the critical health effect. An 8‑hour occupational exposure limit (OEL) of 130 mg/m3 and 15-minute short term exposure limit (STEL) of 650 mg/m3 (i.e. five-fold the value of the OEL) were derived.

ANSES has also released a review and assessment of the health risks posed to workers and the general public by crystalline silica.
