Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- The adsorption coefficient (Koc) value of test substance was estimated to be 9850 calculated using a logKow and a regression derived equation.
- Executive summary:
Adsorption study was conducted for estimating the adsorption coefficient (Koc) value of test chemical. The adsorption coefficient (Koc) value was calculated using a logKow of 4.81 and a regression derived equation. The adsorption coefficient (Koc) value of test substance was estimated to be 9850 (Log Koc = 3.4). This Koc value indicates that the test chemical has a strong sorption to soil and sediment and therefore have negligible to slow migration potential to ground water.
