Overview of Literature on Potential Effect of Cu, Cd, Zn, Mn, Fe and Pb on Marine Phytoplankton

This dataset compiles previously published literature reporting threshold concentrations and toxicological responses of marine phytoplankton to dissolved trace metals. The dataset focuses on copper (Cu), cadmium (Cd), zinc (Zn), manganese (Mn), iron (Fe), and lead (Pb), and includes both field-based and laboratory-based experimental studies. For each study, the dataset records the geographic location of phytoplankton collection, the experimental setting or type (in-situ, on-board, or on-land laboratory experiments), the growth medium used (where applicable) and the dissolved trace metal investigated. Reported threshold concentrations (nM) include LC50 or IC50 values, along with exposure duration and response variables (e.g., growth rate, cell density, chlorophyll-a content, or pigment concentration) where available. The dataset further documents the observed biological impact, phytoplankton taxonomic identity, and full bibliographic references to the original studies. All values are reported as published in the source literature, including associated uncertainties, to preserve comparability and transparency. This dataset is intended to support meta-analyses, environmental risk assessments, and studies on trace metal toxicity and biogeochemical cycling in marine ecosystems.本数据集汇编了已发表的相关文献，这些文献报道了海洋浮游藻类针对溶解态痕量金属的临界浓度与毒理学响应。本数据集聚焦于铜（Cu）、镉（Cd）、锌（Zn）、锰（Mn）、铁（Fe）与铅（Pb），涵盖野外与实验室两类实验研究。 针对每项研究，数据集记录了浮游藻类的采集地理位置、实验设置或类型（原位、船基或陆地实验室实验）、所用培养基（若适用）以及所研究的溶解态痕量金属。已报道的临界浓度（单位为纳摩尔，nM）包含半致死浓度（LC50）与半抑制浓度（IC50）值，同时记录暴露时长与响应变量（如生长速率、细胞密度、叶绿素a含量或色素浓度等，若有相关数据）。本数据集还进一步记录了观测到的生物学影响、浮游藻类的分类学归属，以及原始研究的完整参考文献。所有数据均按源文献发表时的原样呈现，包含相关不确定性，以保障研究的可比性与透明度。 本数据集旨在支持元分析、环境风险评估，以及针对海洋生态系统中痕量金属毒性与生物地球化学循环的相关研究。
