Dioxin-like activity of the crude sediment extracts and the multilayer fractions in the RTL-W1 and H4IIE.luc assays expressed as biological toxicity equivalents (Bio-TEQ) in pg/g dw.

n.d. = not detectable/below detection limit.Data are given as means of 3 replicates ± SD. If no standard deviation is given, Bio-TEQ values could only be calculated for one single triplicate.n.d. 代表未检出（not detectable）或低于检测限（below detection limit）。数据以3次平行重复测定的平均值±标准偏差（standard deviation，SD）表示。若未提供标准偏差，则仅可基于单组三份平行重复样本计算生物毒性当量（Bio-TEQ）值。
