Description of key information

Results from acute and chronic toxicity studies demonstrate that DINP does not cause any adverse effects up to a nominal concentration of 10000 mg/kg soil d.w..

Key value for chemical safety assessment

Additional information

The short-term toxicity of DINP was measured by mortality to the earthworm (Eisenia fetida) in a 14-day study using natural and artificial soils. The long-term toxicity of DINP was measured by reproduction to the earthworm (Eisenia fetida) in a 56 day study using an artificial soil. No significant mortality was observed in natural and artificial soils dosed with DINP after 14 days at a nominal loading rate of 10,000 mg/kg soil (dw), which measured 7270 mg/kg natural soil (dw) and 7372 mg/kg artificial soil (dw) (concentrations are from analyses of soils at test initiation). DINP did not effect earthworm (Eisenia fetida) reproduction, based on a 56-day limit study in artificial soil at a high measured concentration of 982.4 mg/kg soil (dw).
