Proposal of a Testing Program for the Hp14 (Ecotoxic) Classification of Automotive Shredder Residues (Asr) by a Battery of Ecotoxicological Bioassays

Abstract

This manuscript describes a full procedure to be used in performing HP 14 classification of Automotive Shredder Residue (ASR). Sampling instructions and conditions for the transport and storage of ASR samples are included. Additionally, the steps to be followed in preparation of test portions (both solid samples and water extracts) prior to chemical characterization and subsequent ecotoxicological testing are defined. The established test battery includes all bioassays proposed in Pandard and Römbke (2013). Only aquatic bioassays are proposed as mandatory in this paper, which leaves the possibility of performing tests on terrestrial organisms based on the results of chemical characterization of the solid samples. Finally, the proposed set of concentration limits triggering HP 14 classification is fully consistent with thresholds described by Hennebert (2018a).

“…A proposed decision tree is shown in Figure 2. A practical application to the HP 14 classification of typical mirror entry waste (i.e., Automotive Shredder Residue) is also proposed in Pivato et al, (2020).…”
