中文摘要 | 探討汞、銅、鎘與鋅等四種重金屬對中國對蝦之初期幼蟲與蝦苗之急 速毒性,由半致死濃度顯示,後期幼蟲對重金屬毒性之抵抗力大於初期幼蟲。 對初期幼蟲之毒性強度依序為汞 >銅 > 鎘 > 鋅,對 PL5之相對毒性為汞 > 銅 > 鎘 > 鋅,對於 PL12及PL20其毒性強度則稍有不同,相對毒性依序為汞 > 鎘 > 銅 > 鋅。以上四種重金屬對中國對蝦之初期幼蟲與後期幼蟲皆隨期數增加, 容忍度增加,但隨暴露時間增加對蝦苗之毒性則有抵抗力下降之趨勢。 |
英文摘要 | Acute toxicities of heavy metals including mercury, copper, cadmium and zinc to the larva and juvenile of Penaeus chinensis were examined. The postlarvae had higher resistance to these heavy metals than zoea and mysis larvae. The relative toxicities of heavy metals on zoea, mysis and PL5 were as follows: Hg2+ > Cu2+ > Cd2+ > Zn2+. The relative toxicities on PL12 and PL20 were as follows: Hg2+ > Cd2+ > Cu2+ > Zn2+. For both postlarvae, zoea and mysis, tolerence of animal to these heavy metals increased with growth. However, LC50 value decreased with time exposure for every larvae tested. |
