Toxicity of Heavy Metals in Seawater to Juvenile Heart Urchins (Abatus spp)

These data sets describe the toxicity of lead, coppyer, zinc and cadmium spiked seawater to the juveniles of Abatus ingens and Abatus nimrodi. Metals were tested separately over exposure periods of 96 and 240 hours. The experimental endpoint was mortality as defined by cessation of observable movement.The coding system for the data files is J(juvenile)_An (Abatus nimrodi) or Ai (Abatus ingens) - Metal name_Dates of the experiment_ the period of the observation (96 hour or 240 hour).This work falls under the umbrella project ASAC_2201.The fields in this dataset are:SpeciesToxicantDateReplicateConcentrationMovingpHSalinityDissolved Oxygen

本数据集记录了铅、铜、锌及镉配制的加标海水对强壮异海胆（Abatus ingens）与尼姆罗德异海胆（Abatus nimrodi）幼体的毒性效应。实验针对各金属单独开展，分别设置96小时与240小时两个暴露时长。实验终点为死亡，判定标准为个体停止可观测到的运动。数据文件命名规则如下：J（幼体，juvenile）_An（尼姆罗德异海胆，Abatus nimrodi）或Ai（强壮异海胆，Abatus ingens）- 金属名称_实验日期_观测时长（96小时或240小时）。本研究隶属于ASAC_2201总项目。本数据集包含以下字段：物种、受试毒物、实验日期、重复组、毒物浓度、活动个体数、水体pH值、盐度、溶解氧。
