Description of key information

According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE , study for effects on terrestrial organisms and plants need not be conducted if: - These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely. Bioaccumulation is considered to be low for S-allyl O-pentyl dithiocarbonate which is rapidly metabolised in higher organisms.  The estimated Log BCF of S-allyl O-pentyl dithiocarbonateis 1.864 (BCF = 73.06 L/kg wet-wt). This substance has a limited potential to bioaccumulate (based on log Kow used by BCF estimates: 3.33, and predicted bioconcentration factors, log BCF = 1.864 (EPIWIN/BCF Program).  Two evidences result in the conclusion that S-allyl O-pentyl dithiocarbonate is not expected to be B/vB:  -The chemical belongs to the xanthate and xanthate esters group. In general, xanthate esters are absorbed via the skin, mucous membranes, respiratory and gastrointestinal tracts, with rapid elimination via expired air and urine. - Xanthate esters are also rapidly metabolised, producing either mercapturic acid compounds or compounds that enter the carbon metabolic pool  Therefore,S-allyl O-pentyl dithiocarbonate is not considered to be bioaccumulative and secondary poisoning is not considered relevant.
