A series of experiments were conducted to develop standard test organisms and test protocols for measuring sediment toxicity
using candidate amphipods such asMandibulophoxus mai, Monocorophium acherusicum, Haustorioides indivisus, andHaustorioides koreanus, which are indigenous to Korea. The relevant association of test species with sediment substrates was one of the important
factors in sediment bioassay. The indigenous amphipodsM. mai andM. acherusicum were well associated with test sediments when they were exposed to various sediment substrates from sand to mud. The tolerant
limits to various physico-chemical factors affecting bioassay results such as temperature, salinity and ammonia, as well as
sensitivities to reference toxicant and contaminated sediments, were investigated usingM. mai andM. acherusicum in the present study. These amphipods were tolerant to relatively wide ranges of salinity (10~30 psu) and ammonia (<50 ppm),
and displayed relevant sensitivity to temperature as well. They are more sensitive to Cd, the reference toxicant, when compared
to the standard test species used in other countries. Field-sediment toxicity tests revealed thatM. mai would be more sensitive to sediment-associated pollutants thanM. acherusicum, while the sensitivity ofM. acherusicum was comparable to that ofLeptocheirus plumulosus, which has been used as a standard test species in the United States of America. Overall results of this first attempt to
develop an amphipod sediment toxicity test protocol in Korea indicated thatM. mai andM. acherusicum would be applicable in the toxicity assessment of contaminated sediments, following the further evaluation encompassing various
ecological and toxicological studies in addition to test method standardization. 相似文献
