“…Negative and positive correlations occur with about equal frequency, suggesting that, if present, the principal di erential may be either a lower or higher body burden in parasitic tissue. This expectation di ers from that expected from Sures et al (1999).…”

“…More recently, however, research has begun documenting an alternative explanation; the di erential in body burden between parasites and their hosts may accrue from di erential a nities for contaminant accumulation. Zimmerman et al (1999), Sures et al (1999), andHeinonen et al (2001) provide salient examples. Although this potential is not yet included in models of contaminant body burden (e.g., Fraysse et al, 2002;Lee et al, 2002;Yamamoto et al, 2003), this realization leaves the obvious quandary for sentinel bivalves of whether parasite body burden by their tissue contribution in uences the measured value for the host organism as a whole.…”

“…Mercury concentration in liver of the host was three times higher than in the parasite. The opposite pattern was observed for the concentration of lead (Pb) and cadmium (Cd) in freshwater fish and the parasites belonging to the acanthocephalan and cestode groups (Sures et al, 1999).…”

“…Knowledge of the parasites is important not only to learn about fish health but also to evaluate environment quality (Sures, 2001). In aquatic habitats, the use of fish parasites as bioindicators of pollution has been demonstrated to be particularly suitable due to their capacity of bioconcentration (Sures et al, 1999;Sures, 2001;Sures et al, 2003).…”

“…Most studies conducted to evaluate the use of fish parasites as bioindicators of heavy metals have selected the parasites as sentinels (Sures et al, 1999Sures, 2001). Eco-parasites such as monogeneans and crustaceans were not indicated as sentinels because they can be affected by surrounding water and because most are probably similar in their bioaccumulation pattern related to free-living specimens (Sures, 2004).…”

Fish parasites can accumulate heavy metals reaching higher concentrations than the host and may affect the host's bioaccumulation. The present study compared total mercury concentration in the liver and muscle of Cyphocharax gilbert and in the parasite Riggia paranensis sampled in the middle Itabapoana River, Brazil, also considering the reproductive stages of both fish and parasite. Mean concentrations of mercury in muscle of fish varied from 20.8 ng.g -1 in mature females to 38.1 ng.g -1 in postspawning females. The mean concentrations in fish liver varied from 60.9 ng/g in post-spawning females to 110.4 ng.g -1 in infested males. The mean concentration of mercury in parasites varied from 26.2 ng.g -1 in specimens carrying early embryo to 39.5 ng.g -1 in specimens with eggs. Positive and significant associations (P≤0.05) were found between the total mercury concentrations in parasites and muscle of host (both females and males), and between concentrations in parasites and in the liver of male hosts. These results suggest that R. paranensis can be used to indicate mercury levels in edible parts of C. gilbert.Parasitos de peixes podem acumular metais pesados em concentrações acima dos hospedeiros, podendo afetar a bioacumulação nestes. O presente estudo comparou a concentração total do mercúrio no fígado e no músculo de Cyphocharax gilbert e no parasito Riggia paranensis, coletados no trecho médio do rio Itabapoana, Brasil, considerando o estágio reprodutivo tanto dos peixes como dos parasitos. A concentração média do mercúrio nos músculos dos peixes variou entre 20,8 ng.g -1 nas fêmeas maturas e 38,1 ng.g -1 nas fêmeas desovadas. As concentrações médias nos fígados dos peixes variaram entre 60,9ng/g em fêmeas desovadas e 110,4 ng.g -1 em machos parasitados. Entre os parasitos, as concentrações médias de mercúrio variaram entre 26,2 ng.g -1 em espécimes com embriões iniciando o desenvolvimento to 39,5 ng.g -1 em espécimes com ovos . Associações positivas e significativas (P≤0.05) foram encontradas entre as concentrações totais de mercúrio em parasitos e músculos dos hospedeiros (tanto em macho como em fêmeas) e entre as concentrações nos parasitos e os fígados dos hospedeiros machos. Estes resultados sugerem que o parasito R. paranensis pode ser utilizado como bioindicador dos níveis de mercúrio nas partes comestíveis de C. gilbert.

Fish gill mucous is used as a nondestructive biomarker for the detection of heavy metals by sono‐square‐wave anodic stripping voltammetry (sono‐SWASV). The mucous sample was obtained by gently rinsing the rainbow trout (Salmo gairdneri) with a solution of borate buffer at pH 7. A glassy carbon electrode plated in situ with mercury was used in a face on arrangement with the ultrasonic horn to first demonstrate that voltammetric measurements can accurately be made in borate buffer. The optimum deposition potential and ultrasound power for copper from a dilute mucous solution was then determined and used to give a quantitative assessment of copper content using the microaddition technique. The results had a % RSD of less than 2 % and compared favorably with an independent blind analysis. The potential of the technique for detection of other heavy metals for example lead, was also demonstrated. We conclude that sono‐SWASV of gill mucous may present a novel alternative to the destructive conventional techniques due to its accuracy, rapidity and facile methodology.
