The aim of this study was to compare the sensitivity of two Corophidae: Corophium orientale a standardized species and Corophium insidiosum a species more available in the Ionian sea (Southern Italy), in order to evaluate the suitability and applicability of C. insidiosum to sediment toxicity test. The sensitivity of the 2 species was compared through simultaneous bioassays: the 96-h static water-only toxicity test and a 10-day static sediment toxicity test. Sediment samples were collected in the Livorno harbour (Ligurian Sea). Both amphipods showed high sensitivity to reference toxicant and no significant differences were found between the two Corophiidae (t test; p > 0.05). Numerical Sediment Quality Guidelines (SQGs) have been used to relate the chemical concentrations of sediment samples to biological effects. Both amphipod species indicated the same sediment samples as potentially toxic according to chemical data. The results indicate that Corophium insidiosum would be suitable as an alternative test species to the recommended species C. orientale, in the development of sediment toxicity test.
东方沼虾（标准化物种）和 insidiosum 沼虾（一种在意大利南部的伊奥尼亚海更为常见的物种），以评估 insidiosum 沼虾在沉积物毒性测试中的适用性和可行性。通过同时进行生物测定来比较这两个物种的敏感性：96 小时静态水毒性试验和 10 天静态沉积物毒性试验。沉积物样本取自利沃诺港（利古里亚海）。两种端足目甲壳动物对参考毒物均表现出高度敏感性，两种 Corophiidae 之间没有发现显著差异（t 检验；p>0.05）。数值沉积物质量指导值（SQG）已被用于将沉积物样本的化学浓度与生物效应联系起来。根据化学数据，两种端足目甲壳动物都将相同的沉积物样本标记为潜在有毒。结果表明，在开发沉积物毒性测试时，insidiosum 沼虾可以作为推荐物种东方沼虾的替代测试物种。
