Probabilistic determination of the ecological risk from OTNE in aquatic and terrestrial compartments based on US-wide monitoring data.

OTNE [1-(1,2,3,4,5,6,7,8-octahydro-2,3,8,8-tetramethyl-2-naphthyl)ethan-1-one; trade name Iso E Super] is a fragrance ingredient commonly used in consumer products which are disposed down the drain. This research measured effluent and sludge concentrations of OTNE at 44 US wastewater treatment plants (WWTP). The mean effluent and sludge concentrations were 0.

An Integrated Assessment Scheme for assessing the adequacy of (eco)toxicological data under REACH.

REACH requires all available (eco)toxicological information, whether protocol studies, other experiments, or non-testing approaches such as read-across or (Q)SAR, to be collected and evaluated. However, guidance documents only limitedly address how adequacy of (eco)toxicological information can be assessed consistently and transparently. We propose an Integrated Assessment Scheme (IAS) for the evaluation of (eco)toxicological data.

Influence of laboratory storage on the organic contaminant content and water-extractable ecotoxicological potential of soil samples.

At present there is a high level of uncertainty about whether or not soil samples, which are required to be toxicologically characterized, could be preserved without affecting their toxicological characteristics. In the existing DIN/ISO standards for soil investigations, there is no documentation on the storage of soil samples after collection for (eco-)toxicological investigations. Furthermore, procedures for receiving justifiable and verifiable results from soil samples are quite vague.
