Workers - Hazard for the eyes

Additional information - workers

The inhalation DNEL for acute toxicity is unnecessary to be derived because no acute toxicity hazard (leading to C&L) has been identified and there is not a potential for high peak exposures. For the inhalation, dermal and oral exposure routes, ‘short-term’ exposures will be assessed using the long-term DNELs.

In relation to repeated dose toxicity, a NOAEL of 1000 mg/kg bw/day was derived from a 28-day study in which male and female rats were dosed with BDP at concentrations of up to 1000 mg/kg bw/day (assuming 83%, 20% and 100% absorption by the oral, dermal and inhalation route respectively).

In line with Guidance on Information Requirements and Chemical Safety Assessment (2008), the overall AF for oral and dermal repeated dose toxicity is 300. This is established by taking into account an interspecies factor of 10 (4 for metabolic size differences × 2.5 for sensitivity differences), an intraspecies factor of 5, and a further factor of 6 to allow for subacute to chronic extrapolation. The overall AF for inhalation repeated dose toxicity which should be applied to the corrected NOAEC (1000 mg/kg bw/day/3/kg/day×0.83 ×6.7 m3/3) is 75. This is established by taking into account an interspecies factor of 2.5 (for sensitivity differences), an intraspecies factor of 5, and a further factor of 6 to allow for subacute to chronic extrapolation.

In line with Guidance on Information Requirements and Chemical Safety Assessment (2008), the overall AF forreproductivetoxicity is50. This is established by taking into account an interspecies factor of 10 (4 for metabolic size differences × 2.5 for sensitivity differences)andan intraspecies factor of 5.
