“…Discussion Halbach (1984) was among the first person to use population growth as a tool for evaluating the effects of toxicants. Several workers later have used this approach for many species of rotifers such as B. plicatilis, B. calyciflorus and B. patulus to quantify the effects of pesticides (i.e., DDT, lindane, thiophanate-methyl, glyphosate, diazinon, fenitrothion, methoprene, isoprothiolane, cypermethrin, deltamethin, dicofol, endosulfan, atrazine and carbaryl) Sarma, 1986, 1990;Janssen et al, 1994;Xi and Feng, 2004;Chu et al, 2005;Marcial et al, 2005;Xi et al, 2007;Huang et al, 2011;Lu et al, 2012) and other pollutants (i.e., growth hormone, human chorionic gonadotropin, 17b-estradiol, triiodothyronine, 20-hydroxyecdysone, 5-hydroxytryptamine, c-aminobutyric acid, juvenile hormone, ethinylestradiol, nonylphenol, testosterone, phthalate acid esters and melamine) (Gallardo et al, 1997;Radix et al, 2002;Zhao et al, 2007;Wen et al, 2011).…”

-In China, although the production and use of organochlorine pesticides (OCPs) have been banned for decades, relatively high levels of OCP residues have still been found in some water bodies, and can result in adverse acute and chronic effects on zooplankton including rotifers, which have caused public concern for many years. Responses in the population growth and reproduction of freshwater rotifer Brachionus calyciflorus to four OCPs including aldrin, dieldrin, b-hexachlorocyclohexane (b-HCH) and chlordecone were studied by 3-day population growth and 4-day resting eggs (RE) production tests. In comparison with control, aldrin at 10 mg.L x1 , b-HCH at 1000 mg.L x1 and chlordecone at 0.05 mg.L x1 significantly increased the population growth rate (r); but aldrin at 100 mg.L x1 , dieldrin at 0.001 and 0.1 mg.L x1 , b-HCH at 0.1-100 mg.L x1 and chlordecone at 50 mg.L x1 markedly decreased it. Aldrin at concentrations higher than 1 mg.L x1 , dieldrin at 0.01 and 1000 mg.L x1 , b-HCH at concentrations 0.1 and higher than 1 mg.L x1 , and chlordecone at concentrations 0.005 and higher than 0.5 mg.L x1 significantly decreased the ratio of ovigerous females to non-ovigerous females (OF/NOF), but the reverse was true for aldrin at 0.1 mg.L x1 and b-HCH at 0.001 mg.L x1 . Dieldrin at 0.001, 0.01 and 1000 mg.L x1 significantly decreased the ratio of mictic females to amictic females (MF/AF), but b-HCH at 1 and 10 mg.L x1 highly significantly increased it. Dieldrin at 1000 mg.L x1 and b-HCH at concentrations higher than 10 mg.L x1 markedly decreased the fertilization rate (FR). Both aldrin and chlordecone have no significant effect on the MF/AF and FR of rotifers. Aldrin at concentrations higher than 1 mg.L x1 , dieldrin at lower than 0.1 and higher than 10 mg.L x1 , b-HCH at 1000 mg.L x1 and chlordecone at 0.005, 0.05 and 50.0 mg.L x1 significantly decreased the mictic rate (MR) of rotifers, but the reverse was true for b-HCH at 1 mg.L x1 . Aldrin at 10 mg.L x1 , dieldrin at 0.001, 0.1 and 1000 mg.L x1 , b-HCH at concentrations higher than 1 mg.L x1 and chlordecone at concentrations higher than 0.005 mg.L x1 markedly decreased RE production of rotifers, but b-HCH at 0.01 mg.L x1 significantly increased it. A clear dose-response relationship existed between the RE and the concentration of dieldrin, b-HCH and chlordecone, and the OF/NOF and the aldrin concentration. The RE and OF/NOF in rotifer population might be suitable endpoints for monitoring the low concentration of three OCPs (dieldrin, b-HCH and chlordecone) and aldrin, respectively.

“…Dieldrin, in contrast, was shown to decrease the proportion of male offspring in the population (Dodson et al, 1999). Even though juvenile hormone, estrogens and other vertebrate hormones have been shown to impact rotifers, androgen agonists and antagonists seem to have the strongest impact (Gallardo et al, 1997;Preston et al, 2000). Rotifers therefore seem to be a good candidate for the study of endocrine disruption by androgens.…”

“…The other, more classical environmental contaminants, such as pesticides, have also been shown to interfere with the endocrine signaling in aquatic animals (Guillette et al, 1996;Mathiessen & Gibbs, 1998). Studies by Snell and his collaborators (Snell & Carmona, 1995;Gallardo et al, 1997;Preston et al, 2000) indicate that rotifers may be affected by chemicals via endocrine disruption. For example, Preston et al (2000) observed depression of fertilization rate in Brachionus calyciflorus upon exposure to nonylphenol (estrogen agonist), testosterone (androgen agonist) and flutamide (androgen antagonist).…”

The aim of the workshop on rotifers in ecotoxicology was to stimulate discussions on new developments in the field. Discussions about the use of biomolecular tools indicate that gene expression analysis with rotifers should be available in the next few years. Such analyses will be a great asset as they enable ecotoxicologists to study molecular mechanisms of toxicity. Rotifers also appear as useful tools in the risk assessment of pharmaceuticals and their metabolites that find their way into aquatic ecosystems because their sensitivity to some of these substances is higher than that of cladocerans and algae. The nature and extent of the impact of potential endocrine disruptors on aquatic invertebrates is another poorly resolved issue for which rotifers are a promising tool. Indeed, rotifers seem to be particularly sensitive to androgenic and anti-antiandrogenic substances, whereas copepods and cladocerans are typically more affected by estrogens and juvenile hormone-like compounds. Besides their usefulness in these emerging fields of aquatic ecotoxicology, it was emphasized that research with rotifers on basic issues like, e.g., toxicant interference with predation, competition, or interspecific and interclonal variation in ecotoxicological tests is still needed.
