MINTEQ软件对不同水参数条件下铜形态分布进行模拟,辅助解释实验现象,发现钙、镁、钠、钾离子对铜形态分布影响较小.DOC的加入则使络合态铜含量增加,而pH升高导致游离态铜浓度下降,水合态铜浓度升高.本研究表明,预测铜对剑水蚤的毒性要充分考虑水质参数的影响,BLM在铜对剑水蚤的毒性预测方面表现了非常好的应用潜力.","authors":[{"authorName":"陈瑞","id":"c604b28e-32ef-4aea-b743-9633e69670a7","originalAuthorName":"陈瑞"},{"authorName":"吴敏","id":"207593ee-b55b-47bf-ada2-b1399276abd8","originalAuthorName":"吴敏"},{"authorName":"王万宾","id":"4dd79617-a323-4612-a43a-42d4425a64e1","originalAuthorName":"王万宾"},{"authorName":"吴爱民","id":"a1946d23-30a5-4bc6-82f9-d5f60d4ef65b","originalAuthorName":"吴爱民"},{"authorName":"赵婧","id":"30711d6e-1cd1-43be-898c-d8042fe3712c","originalAuthorName":"赵婧"},{"authorName":"陈季康","id":"e835b23a-4e67-46c8-ba05-6eba377480cc","originalAuthorName":"陈季康"},{"authorName":"潘波","id":"a811fe3a-a334-4f6d-a897-cfddab8a144c","originalAuthorName":"潘波"}],"doi":"10.7524/j.issn.0254-6108.2017.04.2016072602","fpage":"716","id":"060b95c8-14f5-4b05-b926-809a436869ee","issue":"4","journal":{"abbrevTitle":"HJHX","coverImgSrc":"journal/img/cover/HJHX.jpg","id":"43","issnPpub":"0254-6108","publisherId":"HJHX","title":"环境化学
