| Popis: | The role of echinoid parental nutrition in early-life stage toxicity is not well understood. Arbacia punctulata were fed either a fresh diet consisting of organic lettuce and carrots or a dry feed. Embryos from parents fed the dry feed exhibited lower sensitivity to copper, whereas the opposite occurred with 1,3,5-trinitrobenzene and sodium dodecyl sulfate (SDS). EC(50) values for the dry and fresh feed treatments, respectively, were 41.0 and 29.9 microg/L for copper, 0.5 and 1.8 mg/L for 1,3,5-trinitrobenzene, and 3.5 and 5.6 mg/L for SDS. The data suggests that nutritional standardization for sea urchins in ecotoxicological laboratories needs to be addressed and further investigated. |
