| 摘 要： | 研究了稀土元素镧与铈对盐卤虫（Ａｒｔｅｍｉａｓａｌｉｎｅ）的急性致毒效应。盐卤虫在硝酸镧溶液中暴露１２、２４、４８、７２、９６ｈ的中间忍受限分别为８９７８、８１４１、６９１２、６７１４、６６４７ｍｇ·Ｌ－１，在硝酸铈溶液中暴露１２、２４、４８、７２、９６ｈ的中间忍受限分别为９０７５、９０１１、６４００、４５００、４０００ｍｇ·Ｌ－１。稀土元素镧、铈对盐卤虫属低毒物质。

| Abstract: | The actuate toxicitive effecting of lanthanum and cerium on brine shrimp ( Artemia saline ) was studied The TLM of brine shrimp when exposures in La(NO 3 ) 3 ·6H 2 O after 12、24、48、72 and 96 h are 89 78、81 41、69 12、67 14 and 66 47 mg·L -1 The TLM of brine shrimp when exposures in Ce(NO 3 ) 3 ·6H 2 O after 12、24、48、72 and 96 h are 90 75、90 11、64 00、45 00 and 40 00 mg·L -1 Both the lanthanum and cerium are low toxic substance for brine shrimp |
