“…In general, water with higher hardness has an effect on reducing toxicity (Sprague, 1995;Yim et al, 2006;Deleebeeck et al, 2007;Ebrahimpour et al, 2010). This effect results from the competition for the biotic ligand between metals and other elements in solution, including calcium (Di Toro et al, 2001).…”

Water hardness is a property depending on the presence of alkaline earth metals, mainly calcium and magnesium. Among the strategies for water quality monitoring, ecotoxicological assays are performed to minimize impacts and classify water bodies. For these laboratory evaluations parameters are previously defined in the guidelines, including water hardness for both cultivation and testing medium. The present work was performed to evaluate the effects of different levels of water hardness on the survival and reproduction of the freshwater snail Biomphalaria glabrata and discuss the influence of natural water hardness on the results of ecotoxicological tests with these environmental samples. Comparing the groups it was possible to observe that those maintained in waters with least hardness had lower reproductive success, while the groups maintained in highest hardness showed better reproduction. These data show that waters with low hardness make the reproduction of the snail B. glabrata unfeasible, and this reveal a problem for ecotoxicity assays using natural water samples.Keywords: ecotoxicology, biological assays, standard methods, guidelines, environmental factors.Implicações da dureza da água nas avaliações ecotoxicológicas com propósitos reguladores de qualidade da água: um estudo de caso com o caramujo aquático Biomphalaria glabrata ResumoA dureza da água é uma propriedade dependente da presença de metais alcalino terrosos, principalmente cálcio e magnésio. Entre as estratégias para monitorar a qualidade da água ensaios ecotoxicológicos são realizados para minimizar impactos e classificar os corpos hídricos. Para essas avaliações em laboratório, parâmetros são previamente definidos nos protocolos, incluindo a dureza da água para cultivo e para a água de diluição. O presente trabalho foi realizado para avaliar os efeitos de diferentes níveis de dureza da água sobre a sobrevivência e a reprodução do caramujo de água doce Biomphalaria glabrata e discutir a influência da dureza de águas naturais nos resultados dos testes ecotoxicológicos com estas amostras ambientais. Comparando os grupos foi possível observar que aqueles mantidos em águas com menor dureza tiveram pior sucesso reprodutivo, enquanto os mantidos nas águas com maiores durezas tiveram melhor reprodução. Esses dados mostram que águas com baixas durezas tornam a reprodução do caramujo B. glabrata inviável, e esse fato revela-se como um problema para os ensaios ecotoxicológicos utilizando amostras de água naturais.Palavras-chave: ecotoxicologia, ensaios biológicos, métodos padrão, protocolos, fatores ambientais.

“…Bioaccumulation of As, Co, Cr and Mn in Hyalella azteca was useful for predicting chronic mortality based on a saturationbased mortality model relative to total-body or water metal concentration [140]. The acute toxicity of the metal mixture to D. magna could be well predicted when the modified LC 50 values was employed as the basis of hardness in the toxic unit (TU) calculation, which was useful in the prediction of acid mine drainage toxicity [141]. Biotic ligand models (BLMs) have been developed for various metals (e.g.…”

“…For a fixed number of gill ion-exchange sites, increased hardness decreases the concentration of toxic metals and thus their uptake by fish (Gundersen, Bustaman et al 1994;Yim, Kim et al 2006 (Yim, Kim et al 2006).
