Distribution of propranolol in water, biota and sediment.

Concentration of propranolol in water (μg l−1), biota (μg g ww−1) and sediment (μg g ww−1). Bioconcentration factor (BCF: (mg kg ww−1)/(mg l−1))) determined for mussels and amphipods and concentration factor (CF: (mg kg ww−1)/(mg l−1)) for sediment. Propranolol distribution (%) among the components in the microcosms (assuming a similar concentration in the algae as in the amphipods). Quantifications made after exposure to propranolol in 0 (Control); 100 μg l−1 (P100) and 1000 μg l−1 (P1000), mean±se. One mussel replicate from P1000 (one individual) showed a considerably higher concentration of propranolol (310 μg g ww−1) and BCF (295) than the other analysed individuals from the same treatment, and was excluded from the overall mean. LOQ = level of quantification, ww = wet weight.本数据集涵盖水体、生物群落及沉积物中普萘洛尔（propranolol）的浓度数据，其浓度单位分别为微克每升（μg l⁻¹）、微克每克湿重（μg g ww⁻¹）与微克每克湿重（μg g ww⁻¹）。针对贻贝与端足类动物测定了生物浓缩因子（bioconcentration factor, BCF，计算公式为(mg kg ww⁻¹)/(mg l⁻¹)），针对沉积物则测定了浓缩因子（concentration factor, CF，计算公式为(mg kg ww⁻¹)/(mg l⁻¹)）。本研究统计了微宇宙生态系统各组分中普萘洛尔的分布占比（%），假设藻类中的普萘洛尔浓度与端足类动物一致。所有定量分析均基于三类暴露处理：0 μg l⁻¹对照组（Control）、100 μg l⁻¹处理组（P100）以及1000 μg l⁻¹处理组（P1000），结果以平均值±标准误（mean±se）表示。P1000组中有1个贻贝重复样本（单一个体）的普萘洛尔浓度（310 μg g ww⁻¹）与生物浓缩因子（295）显著高于同处理组的其余分析个体，故将该样本从总体平均值的计算中剔除。其中LOQ为定量限（level of quantification），ww代表湿重（wet weight）。
