BCF Value (F): NR ( NR to NR) - Sublethal observations / clinical signs:
Preliminary testing of eight collectors (xanthates) and four frothers in 96-h static and 28-day flow-through bioassays using rainbow trout as the test organism show a great disparity in the toxicity of the chemicals administered in these two ways.
For the short-term tests, the relative toxicity of the compounds is expressed as an lc50 or as a range of concentration in mg l-1 in which the lc50 is expected to fall. Of the collectors tested in this way sodium ethyl and potassium amyl xanthate were the most toxic, with lc50's in the range of 30-50 mg l-1. Among the frothers, xylenol (cresylic acid) was found to be the most toxic (5.6 mg l-1 >lc50 > 3.2 mg l-1) while polypropylene glycol was least toxic (lc50 > 1000 mg l-1).
The long-term tests using potassium ethyl, sodium isopropyl, sodium ethyl, and potassium amyl xanthate indicated that in the flow-through system, the toxicity of the chemicals was in the order of 100 fold greater compared with the static bioassay results.
- Validity criteria fulfilled:
- yes
- Conclusions:
- Under the conditions of the present test Potassium amyl xanthate induced no mortality in Oncorhynchus mykiss (Rainbow Trout) below 3.6 mg/l (NOEC). One of the 96h-LC50 was 18 mg/l .

The S-allyl O-pentyl dithiocarbonate (CAS No. 2956-12-9), the subject of this dossier) is expected to exhibit very similar toxicity to Carbon disulphide (CS2, (CAS No. 75-15-0)).Carbon disulphide (CAS number 75–15–0) is both reagents used in the manufacture of S-allyl O-pentyl dithiocarbonate. Therefore, Carbon disulphide (CAS number 75–15–0) need to be considered in the assessment of S-allyl O-pentyl dithiocarbonate. Comparable metabolism would occur.

On a molecular weight scaled basis, the LC50 would be 10.63 mg/l. (4 x 204.35) /76.13 =10.74 mg/l - Executive summary:
A semi-static test in a sealed system was carried out to determine the toxicity of CS2 to the fish Poecilia reticulata. The test fulfilled the requirements of OECD Guidline 203 but was not carried out in compliance with GLP. The 96-h LC50 of CS2 for Poecilia reticulata was 4 mg/L.
The S-allyl O-pentyl dithiocarbonate (CAS No. 2956-12-9), the subject of this dossier) is expected to exhibit very similar toxicity to Carbon disulphide (CS2, (CAS No. 75-15-0)).Carbon disulphide (CAS number 75–15–0) is both reagents used in the manufacture of S-allyl O-pentyl dithiocarbonate. Therefore, Carbon disulphide (CAS number 75–15–0) need to be considered in the assessment of S-allyl O-pentyl dithiocarbonate. Comparable metabolism would occur.
On a molecular weight scaled basis, the LC50 would be 10.63 mg/l. (4 x 204.35) /76.13 =10.74 mg/l

Description of key information
The ECOSAR QSAR model predicts that the 96hr LC50 for freshwater fishwould to be 4.573 mg/l therefore the substance is moderately toxic to fishes.
The ECOSAR QSAR model predicts that the 96hr LC50 for marine water fish would to be 6.412 mg/l therefore the substance is moderately toxic to fishes.
