Description of key information

Based on the results, S-allyl O-pentyl dithiocarbonate is readily biodegradable: 73.74 % was degraded in 8 days (at initial pH 7.4 and 25 oC). The calculated half-life (t1/2) was 4.6 d. Xanthates with branched alkyl chains can be expected to have slightly lower rate of biodegradation. The results show the rapid biodegradability of the initial substance, but suggest that the main degradation products which cannot be further mineralised by microbes are carbon disulfide, monothiocarbonate and dixanthogen, which accumulated in the test solution. Despite of that, no significant toxic or inhibitory effects on micro-organisms were observed at an initial test concentration of 30 mg/L.
