| 中文摘要: |
| 以3月龄的鲫( Carassius auratus ) 为实验对象, 研究了氯化三苯基锡( TPTC) 对鲫的急性毒性以及在1 /2LD50、1 /3LD50、1 /4LD50、1 /6LD50亚急性浓度下对鲫死亡率的影响。结果表明, 在较低的TPTC 浓度下, 鲫的概率单位较小, 死亡率较低; 当浓度达到385. 6 Lg /L时, 死亡率超过50%。因此, TPTC 浓度385 Lg /L是一个安全阈值, 当TPTC 浓度达到385 Lg /L以上, 死亡率明显增加。TPTC的对数浓度和概率单位呈现出明显的线性相关; 且TPTC在鲫体内的积累量较大, 难以降解; 鲫对TPTC比较敏感, 可将其作为TPTC毒性测试的标准试验生物。

| 英文摘要: |
| The acute and subacute toxicities effect on mortality under 1 /2LD50、1 /3LD50、1 /4LD50、1 /6LD50 of TPTC on the infancy Carassius auratus were studied. The results showed that : probit unit is less and mortality is lower under the lower concentration , and the mortality exceed by 50% as concentration of TPTC arrived by 385.6Lg /L. Therefore , TPTC concentration less than 385 Lg/L 24h is safely threshold value , the mortality ascend obviously when TPTC concentration arrived by 385 Lg /L. It is obviously that the logarithm concentration and probit unit presents obvious linear correlation . And that the accumulation capacity of TPPC is upper and undecomposed ,moreover, it is sensitive to TPTC , thus Carassius auratus can be as environmental biomarkets of TPTC. |
