“…Aldrin at 0.16-1.28 mg/L prolonged the duration of juvenile period of rotifers by 7.2%-26.6% (Table 1), which was similar to the effects of 17b-estradiol at 0.01, 0.1 and 10.0 lg/L, and chlordecone at 5.0 and 50.0 lg/L (Huang et al 2006;Zha et al 2007). Aldrin at 0.16-1.28 mg/L may directly affect the duration of juvenile period of the rotifers, or/and indirectly affect it by altering the algal quality, because the algal quality affects the duration of juvenile period of the rotifers (Xi and Huang 1999;Xi et al 2001).…”

“…Compared to the controls, acetone at 0.128% did not markedly influenced the duration of embryonic development of rotifers. However, aldrin at 0.04-1.28 mg/ L shortened the duration of embryonic development of rotifers by as much as 18.9%-28.7% (Table 1), which was identical to the effects of dieldrin at 0.01, 0.1 and 10.0 lg/ L, 17b-estradiol at 0.001-0.1 lg/L and 10.0 lg/L, and chlordecone at 5.0 and 50.0 lg/L (Huang et al 2006;Zha et al 2007). Because the algal quality does not affect the duration of embryonic development of the rotifers (King 1967;Xi and Huang 1999), aldrin at 0.04-1.28 mg/L may directly affect the embryonic development of the rotifers.…”

“…As test animals, rotifers have been extensively used to monitor the acute and chronic toxicities of heavy metals, pesticides and other pollutants (Snell and Janssen 1995). By chronic toxicity tests, some researchers investigated the effects of toxicants on the survival and reproduction of rotifers, but few researchers dealt with the effects on the development, including embryonic and juvenile developments of rotifers (Xi and Hu 2003;Chu et al 2005;Xu et al 2005;Huang et al 2006;Zha et al 2007).…”

The organochlorine insecticide aldrin is commonly used in intensive agriculture, and demonstrates estrogenic activity. Rotifers such as Brachionus calyciflorus are favored test animals in aquatic toxicology because of their more sensitivity to most toxicants. In the tested concentration range of 0.04-1.28 mg/L, aldrin shortened significantly the durations of embryonic development. Lower concentrations of aldrin had an intriguing effect on the reproduction of the rotifers and are beneficial to their survival. Different endpoints of both development and reproduction had different sensitivity to aldrin. The reproductive endpoint of the rotifers is more sensitive to aldrin than the developmental endpoint.

a b s t r a c tChlordecone (CLD) is an organochlorine insecticide abundant in aquatic environment of the French West Indies. However, few studies have investigated its impact on freshwater invertebrates. Whereas CLD is suspected of inducing endocrine disruption, this work aimed to study the effects of environmentally relevant concentrations of CLD on the 20-hydroxyecdysone (20-HE) hormone concentration and on the chitobiase activity, both having key roles in the molting process of crustaceans. In addition, the bioaccumulation of CLD was measured in the muscle tissue of Macrobrachium rosenbergii to underline potential dose-response relationship. The results have shown that CLD was bioaccumulated in exposed organisms according to a trend to a dose-response relationship. Moreover, it was observed that CLD decreased the 20-HE concentration in exposed prawns when compared to control, whatever the duration of exposure, as well as it inhibited the chitobiase activity after 30 days of exposure. The present study indicates that CLD could interfere with molting process of M. rosenbergii by disturbing the 20-HE concentration and the activity of chitobiase, suggesting consequences at the long term on the shrimp development. This study also confirmed that CLD could be an endocrine disruptor in decapod crustaceans, as it was already observed in vertebrates.

The Life-Table Demographic Response of Freshwater Rotifer Brachionus calyciflorus to Multi-metal (Cu, Zn, Cd, Cr, and Mn) Mixture Interaction

The effects of multi-metal mixtures on the life-table demography of rotifers are not well known. In this study, the freshwater rotifer Brachionus calyciflorus was exposed to mixture of Cu, Zn, Cd, Cr, and Mn, and the life-table demographic parameters including net reproductive rate, generation time, life expectancy at hatching, and intrinsic rate of population increase were calculated. The results showed that interactions between a given element concentration, except Mn, and the other four elements mixture concentration affected the intrinsic rate of population increase (p < 0.01). Interactions between Zn concentration, as well as Mn, and the other four elements mixture concentration affected the net reproductive rate and the life expectancy at hatching, respectively (p < 0.05). The variation of parameters with the rise of the other four elements mixture concentrations from 0 to high was mainly attributed to the difference of interaction among the five metals mixture with different ratio of concentrations.
