Distribution of DNELs and DMELs over different routes of exposure. A number of registered substances (1,728) showed clear identity and had at least one DNEL or DMEL for workers. In sum, of 4,765 values, app. 60% were derived for chronic systemic exposure via skin and inhalation. The DMELs are part of the displayed columns (orange) and contributed only to a small degree to all values.
