Additional information

A carbon transformation and nitrogen transformation test was conducted in agricultural soil at nominal concentrations of 156, 448 and 2240 kg furfural/ha. Carbon transformation was measured at day 0 and after 7, 14, 28, 42, 56, 70, 84 and 98 days. Nitrogen transformation was assessed on day 0 and after 7, 14, 28, 42, 56 and 70 days. The NOEC was 448 kg furfural/ha (which is equivalent to 597 mg furfural/kg soil assuming a soil depth of 5 cm and a soil density of 1500 kg/m3).
