Methods for the determination of effects of chemicals on organisms arising from atmospheric contamination have not yet been developed, except for inhalation studies with mammals. Therefore, a hazard assessment and in consequence the risk characterisation of chemicals in air cannot be applied. The inhalative uptake of the substance by humans is considered by the assessment of exposure of humans via the environment.

Biodegradation in water was determined in a Modified Storm Test (CO2 Evolutio

Biodegradation in water was determined in a Modified Storm Test (CO2 Evolution Test) by Infracor GmbH (2002) according to the EU method C4 and OECD 301 B. The study was conducted with activated sludge obtained from a municipal WTP. CO2 evolution was quantified via measurement of dissolved organic carbon using a Carbon analyser.

83% degradation were observed within a period of 28 days. As >60% biodegradability were observed within the 10d-window the test item can be assessed as readily biodegradable.

Due to the ready biodegradability further degradation tests in water, sediment and soil are not necessary according to column 2 of Annex IX of REACH Regulation1907/2006.
