In this investigation, an evaluation was made of the lethality of suspended clay mineral texturally representative of the sediment-size fraction with which contaminants are most commonly associated. The study involved a phylogenetically diverse selection of marine and estuarine macrofauna. The time-concentration mortality response of 16 species of fish and invertebrates indicated widely differing sensitivities to high concentrations of clay suspended in the water. Organisms restricted to muddy bottoms were found to be very insensitive to high suspended clay concentrations. However, some open water fish, fouling organisms, and sandy bottom epifauna were found to be relatively sensitive. Tolerant species were also identified from these groups.
在本次调查中，对质地代表沉积物粒度级分的悬浮粘土矿物的致死率进行了评估，而污染物最常与该沉积物粒度级分相关联。该研究涉及从系统发育角度对多种海洋和河口大型动物进行的选择。16种鱼类和无脊椎动物的时间-浓度死亡率响应表明，它们对水中高浓度悬浮粘土的敏感性差异很大。发现局限于泥泞底部的生物对高悬浮粘土浓度非常不敏感。然而，一些敞水区鱼类、污损生物和沙质底部的表栖动物相对敏感。也从这些类群中鉴定出了耐受性物种。
