Description of key information
Adsorption/desorption
KOCWIN model (v2.00) of Estimation Programs Interface (EPI Suite, 2017) was used to predict the soil adsorption coefficient i.e Koc value of test chemical Dialkyl(C1 -C14)dithiophos phoric acid, zinc salt (CAS No. 68649 -42 -3). The soil adsorption coefficient i.e Koc value of Dialkyl(C1-C14)dithiophosphoric acid, zinc salt was estimated to be 144000000 L/kg (log Koc=8.1585) by means of MCI method (at 25 deg C). This Koc value indicates that the substance Dialkyl(C1-C14)dithiophosphoric acid, zinc salt has a very strong sorption to soil and sediment and therefore have negligible migration potential to ground water.

Adsorption/desorption
Predicted data for the target compound Dialkyl(C1-C14)dithiophosphoric acid, zinc salt (CAS No. 68649-42-3) and various supporting weight of evidence studies for its read across substance were reviewed for the adsorption end point which are summarized as below:
In aprediction done using the KOCWIN model (v2.00) of Estimation Programs Interface (EPI Suite, 2017) was used to predict the soil adsorption coefficient i.e Koc value of test chemical Dialkyl(C1-C14)dithiophosphoric acid, zinc salt (CAS No. 68649 -42 -3). The soil adsorption coefficient i.e Koc value of Dialkyl(C1-C14)dithiophosphoric acid, zinc salt was estimated to be 144000000 L/kg (log Koc=8.1585) by means of MCI method (at 25 deg C).
In a supporting weight of evidence study from authoritative database (HSDB, 2017) for the read across chemical 1-Decanaminium, N-decyl-N,N-dimethyl-, chloride (CAS no. 7173-51-5), adsorption batch equilibrium study was conducted using five different soil types for determining the adsorption coefficient (Koc) value of read across chemical 1-Decanaminium, N-decyl-N,N-dimethyl-, chloride. The study was performed according to OECD Guideline 106 (Adsorption - Desorption Using a Batch Equilibrium Method). The adsorption coefficient (Koc) value of substance 1-Decanaminium, N-decyl-N,N-dimethyl-, chloride was determined to be 667 (log Koc = 2.824), 1140 (log Koc = 3.056), 10456 (log Koc = 4.019), 14072 (log Koc = 4.148) and 24433 (log Koc = 4.387), respectively. Thus based on the Koc values (Koc = 10456, 14072 and 24433) indicates that the substance 1-Decanaminium, N-decyl-N,N-dimethyl-, chloride has a very strong sorption to soil and therefore have negligible migration potential to ground water.
For the read across chemical 1-Hexadecanaminium, N,N,N-trimethyl-, chloride (CAS no. 112-02-7), adsorption study was conducted for estimating the adsorption coefficient (Koc) value of read across chemical 1-Hexadecanaminium, N,N,N-trimethyl-, chloride (HSDB, 2017). The adsorption coefficient (Koc) value was calculated using a structure estimation method based on molecular connectivity indices. The adsorption coefficient (Koc) value of substance 1-Hexadecanaminium, N,N,N-trimethyl-, chloride was estimated to be 220000 (Log Koc = 5.342).
In a supporting weight of evidence study from authoritative database (HSDB, 2017) for the read across chemical dimethyl(dioctadecyl)azanium chloride (CAS no. 107-64-2), adsorption experiment was conducted for estimating the adsorption coefficient (Koc) value of read across chemical dimethyl(dioctadecyl)azanium chloride. The adsorption coefficient (Koc) value was calculated using a log Kow of 3.80 and a regression derived equation. The adsorption coefficient (Koc) value of substance dimethyl(dioctadecyl)azanium chloride was estimated to be 10000000000 (Log Koc = 10).
On the basis of above overall results for target chemicalDialkyl(C1-C14)dithiophosphoric acid, zinc salt(from EPI suite,2017) and for its read across substance (from authoritative database HSDB, 2017), it can be concluded that the Koc value of test substanceDialkyl(C1-C14)dithiophosphoric acid, zinc saltis144000000 L/kgindicating that the test chemical Dialkyl(C1-C14)dithiophosphoric acid, zinc salt has a very strong sorption to soil and sediment and therefore have negligible migration potential to ground water.
