“…Bioassays with other invertebrates, such as daphnia (Daphnia magna) and Ceriodaphnia (C. affinis or C. dubia), are widely used to detect chronic toxicity (after 21-days exposure) of chemical solutions, environmental and waste waters (Viganò et al, 1996). In several studies the Hydra bioassay, particularly when chronic changes in morphology and reproduction rate were measured, was more sensitive than other bioassays undertaken with invertebrate, vertebrate and plant test organisms (Diaz-Baez et al, 2002;Ronco et al, 2002a;Arkhipchuk et al, 2006b;Oberholster et al, 2008).…”

Hydra have been extensively used for studying the teratogenic and toxic potential of numerous toxins throughout the years and are more recently growing in popularity to assess the impacts of environmental pollutants. Hydra are an appropriate bioindicator species for use in environmental assessment owing to their easily measurable physical (morphology), biochemical (xenobiotic biotransformation; oxidative stress), behavioural (feeding) and reproductive (sexual and asexual) endpoints. Hydra also possess an unparalleled ability to regenerate, allowing the assessment of teratogenic compounds and the impact of contaminants on stem cells. Importantly, Hydra are ubiquitous throughout freshwater environments and relatively easy to culture making them appropriate for use in small scale bioassay systems. Hydra have been used to assess the environmental impacts of numerous environmental pollutants including metals, organic toxicants (including pharmaceuticals and endocrine disrupting compounds), nanomaterials and industrial and municipal effluents. They have been found to be among the most sensitive animals tested for metals and certain effluents, comparing favourably with more standardised toxicity tests. Despite their lack of use in formalised monitoring programmes, Hydra have been extensively used and are regarded as a model organism in aquatic toxicology.

Overall, it has been observed that daphnids have a similar sensitivity to toxic substances (Mount and Norberg 1984;Kline et al 1989) and C. dubia is sometimes more sensitive than the D. magna (Winner 1988;Mokry and Hoagland 1990;Kszos et al 1992).…”

“…The toxicity of a river whose basin is heavily industrialized and urbanized can be caused by many unknown contaminants (Viganò et al 1996). Although toxicity tests could not provide information of probable toxicants present in the environment, Kimerle et al (1985), using this type of test with at least two different species, reported reliable results in relation to the danger of toxic substances in the environment.…”

“…A toxicidade no ponto R5 pode ser devida ao fato de, neste ponto do rio Doce, a água ser utilizada para diversas atividades da população que mora em seu entorno, como lavagem de roupa, área de lazer, banho de animais domésticos, descarte de resíduos de um matadouro, retirada de areia para construção civil e proximidade da Para Viganó et al (1996), a toxicidade de um rio cuja bacia é fortemente urbanizada, como é o caso deste estudo, pode ser causada por vários fatores como descarte de efluentes agrícolas e domésticos, compostos químicos provenientes de áreas agrícolas, descarte inadequado de resíduos de agrotóxicos; além disso, os componentes tóxicos presentes podem se concentrar e se dispersar em diferentes períodos durante o ano. Botelho et al (2013), em estudo que utilizou Ceriodaphnia dubia e Ceriodaphnia silvestrii em amostras ambientais correlacionaram os resultados observados nos ensaios crônicos com amostras ambientais no rio Piracicaba a uma série de fatores.…”

-The aim of this study was to evaluate the water quality of the Rio Doce by analyzing physical and chemical parameters and ecotoxicological tests using Ceriodaphnia dubia Richard, 1894 (Crustacea, Cladocera) and Ceriodaphnia silvestrii as test organisms. Samples were collected monthly from May 2012 to May 2013. The sampling locations were named LE, R2, R3, R4 and R5. The analysis of physical-chemical parameters showed in the sampling period May 2012 to May 2013, the waters of the Doce river to cross the area of R3 and R4 points, in general, had lower values of temperature, pH and chloride. It was also possible to observe difference in the parameters of behavior in relation to the months during the year. The tests of chronic toxicity tests indicated the existence of toxicity to Ceriodaphnia dubia and Ceriodaphnia silvestrii in all sampled points. The alteration found in physical and chemical parameters measured in water and the results of chronic toxicity tests suggest that the many activities surrounding the Basin may be contributing to the observed variations. The factors that influenced the results of the ecotoxicological tests and the physical and chemical parameters indicated in studies stand out proximity of agricultural areas, with consequent indiscriminate use of pesticides, inadequate waste disposal of these products, proximity to traffic routes, in addition to disposal of domestic sewage and urban sprawl, observed along the drainage.

Water quality Resumo -O objetivo deste estudo foi avaliar a qualidade da água do rio Doce por meio da análise de parâmetros físicos e químicos e de ensaios ecotoxicológicos utilizando Ceriodaphnia dubia Richard, 1894 (Crustacea, Cladocera) e Ceriodaphnia silvestrii como organismos teste. As amostragens foram realizadas mensalmente de maio de 2012 a maio de 2013. Os locais de amostragem foram denominados LE, R2, R3, R4 e R5. A análise dos parâmetros físico-químicos evidenciou, no período de amostragem, maio de 2012 a maio 2013, que as águas do Rio Doce ao atravessarem a área dos pontos R3 e R4, de maneira geral, apresentaram valores mais baixos de temperatura, pH e cloreto. Também foi possível observar diferença no comportamento dos parâmetros em relação aos meses ao longo do ano. Os ensaios dos testes de toxicidade crônica indicaram a existência de toxicidade, para Ceriodaphnia dubia e Ceriodaphnia silvestrii, em todos os pontos amostrados. A alteração encontrada nos parâmetros físicos e químicos medidos em água e os resultados dos testes de toxicidade crônica sugerem que as diversas atividades desenvolvidas no entorno da Bacia podem estar contribuindo para as variações observadas. Como fatores que influenciaram os resultados dos testes ecotoxicológicos e dos parâmetros físicos e químicos apontados no estudo pode-se destacar a proximidade de áreas agrícolas, com consequente utilização indiscriminada de agrotóxicos, o descarte inadequado de resíduos destes produtos, a proximidade de vias de tráfego, além do desc...
