Introduction

Deep-water benthic animals that ingest sediments are susceptible to exposure to chemicals contained in sediments. Among the sedimentary ingestors, the oligo-major link Animals play an important role at the bottom of the aquatic ecosystem. They inhabit sediments and are numerous things that survive in harsh environments. Representative of species. By bioturbation or predation in sediments, oligochaetes can treat chemicals to other organisms (such as benthic fish) The bioavailability has an important impact. Unlike shallow benthic organisms, deep-water benthic oligochaetes have burrowing lines in sediments. For, and ingesting sediment particles under the surface of the sediment. Therefore, these organisms can be exposed to chemicals through a variety of pathways, including direct Touching and ingesting sediment particles containing the test substance, sucking pore water and overlying water, and the like. The benthic oligochaetes commonly used in ecotoxicology tests See Appendix A for species. The parameters describing the bioaccumulation of a substance first include the accumulation factor (BAF), followed by the sediment absorption rate constant (ks) and clearance. Rate constant (ke). In general, specific tests should be taken in order to assess the bioaccumulation of chemicals that are easily distributed inside or on the surface of sediments. Method [1-3]. This test method is suitable for assessing the bioaccumulation of sediment-related chemicals in deep-water benthic oligochaetes. Pass by The way the sample is added to the sediment simulates deposits containing chemicals in nature. This test method is based on existing sediment toxicity and bioaccumulation test methods [3-7], and refers to other relevant documents, including international research. The results of the seminar [8] and the verification results of the international comparison test [9]. Benthic oligochaetes in chemical sediments Inter-animal bioaccumulation test

1 Scope

This standard specifies the terms and definitions of the bioaccumulation test of benthic oligochaetes in chemical sediments, and the necessary materials for the test materials. And information, test principles, reference materials, equipment, test systems, test procedures, test effectiveness, data and test reports. This standard applies to stable neutral organic compounds (lgKow value between 3.0 and 6.0 [4,10], easy to combine with sediment), very strong a lipophilic substance (lgKow greater than 6.0) [4], a stable organometallic compound (easy to bind to sediment) [9] and known to have in vivo Bioaccumulative chemicals (such as surfactants or highly adsorbable substances, ie high Koc substances). If the parameters such as the volume of the benthic substrate and water, the size of the biological tissue sample, etc. are not modified in the experimental design, this standard does not apply. Used for testing of metals and other trace elements [8].
