Key value for chemical safety assessment

Additional information

Under the conditions of this present test Triethoxy(3-thiocyanatopropyl)silane was toxic to waste water (activated sludge) bacteria at all loading rates tested (NOEC < 1.0 mg/l).

The EC10 was at a loading rate of 4.3 mg/l (95% confidence interval: 2.0 – 9.3 mg/l).

The EC20 was at a loading rate of 10 mg/l (95% confidence interval: 4.8 - 21 mg/l).

The EC50 was at a loading rate of 130 mg/l (95% confidence interval: 68 – 260 mg/l).

The EC80 was above the highest loading rate tested (> 1000 mg/l).
