Abstract
This research was designed to investigate the acute toxic effect of cadmium chloride on freshwater turtle Mauremys reevesii. Mauremys reevesiis were exposed to a wide range of cadmium chloride by intraperitoneal injection for 7 days and the survival numbers of the animals were noted to determine the dose of cadmium chloride for 0% mortality rate (Dn) and the dose of cadmium chloride for 100% mortality rate (Dm). Karber’s method was used to test the LD50 of cadmium chloride in Mauremys reevesii. The results showed that cadmium has acute toxic effect on freshwater turtle Mauremys reevesii. Dm and Dn were 500 and 20 mg·kg−1 separately. The LD50 value was 89.8 mg·kg−1 for cadmium chloride, with the 95% confidence limit of 85.2–98.5 mg·kg−1. The results indicated that cadmium had acute toxicity on turtle Mauremys reevesii.
期刊介绍：
Aquatic Ecology publishes timely, peer-reviewed original papers relating to the ecology of fresh, brackish, estuarine and marine environments. Papers on fundamental and applied novel research in both the field and the laboratory, including descriptive or experimental studies, will be included in the journal. Preference will be given to studies that address timely and current topics and are integrative and critical in approach. We discourage papers that describe presence and abundance of aquatic biota in local habitats as well as papers that are pure systematic.
The journal provides a forum for the aquatic ecologist - limnologist and oceanologist alike- to discuss ecological issues related to processes and structures at different integration levels from individuals to populations, to communities and entire ecosystems.
