This article contains a dataset of the genotoxic (DNA damage, via the micronucleus frequency test) and cytotoxic (lysosomal membrane stability (cellular integrity), via the neutral red retention test) effects on the pygmy mussel, (Bivalvia: Mytilidae) from variably contaminated sites (primarily from cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb) and zinc (Zn)) in the highly urbanized Sydney Estuary, south-eastern Australia. Data were collected 15 years apart (June 2004 and June 2019) to assess any change in (i) the "health" of mussels (based on the above two toxicity endpoints) and (ii) their metal contaminant status (measured as whole soft tissue concentrations of Cd, Cr, Cu, Pb and Zn). Linear relationships between both toxicity endpoints and metal concentrations in the whole soft tissue were also investigated. Multivariate statistical techniques, including principal components analysis, multidimensional scaling and cluster analysis, were also explored to reduce dimensional data, investigate patterns and assess similarities among study sites with respect to tissue metal concentrations and toxicity effects in . Enrichment factors were calculated by dividing the mean whole soft tissue metal concentration at each site in the Sydney Estuary, by its mean baseline metal concentration from near-pristine (reference) sites in the adjacent Hawkesbury Estuary. Salinity, pH, temperature, turbidity, dissolved oxygen and chlorophyll were measured in the surface waters at each site.
本文包含了一组关于侏儒贻贝（双壳纲：贻贝科）的遗传毒性（通过微核频率试验检测DNA损伤）和细胞毒性（通过中性红保留试验检测溶酶体膜稳定性（细胞完整性））效应的数据集，这些贻贝采自澳大利亚东南部高度城市化的悉尼河口不同污染程度的地点（主要受镉（Cd）、铬（Cr）、铜（Cu）、铅（Pb）和锌（Zn）污染）。数据采集相隔15年（2004年6月和2019年6月），以评估（i）贻贝的“健康状况”（基于上述两个毒性终点）和（ii）它们的金属污染物状况（以整个软组织中Cd、Cr、Cu、Pb和Zn的浓度衡量）的任何变化。还研究了整个软组织中两个毒性终点与金属浓度之间的线性关系。还探索了多元统计技术，包括主成分分析、多维标度分析和聚类分析，以减少数据维度、研究模式并评估研究地点在组织金属浓度和贻贝毒性效应方面的相似性。通过将悉尼河口每个地点整个软组织的平均金属浓度除以相邻霍克斯伯里河口近原始（参考）地点的平均基线金属浓度来计算富集因子。在每个地点的表层水中测量了盐度、pH值、温度、浊度、溶解氧和叶绿素 。
