Is frog a model organism for metal toxicity assay? How much heavy metal-containing meals do frogs consume? What does the literature say about effect of heavy metals on frogs? How many people consume frog meat? People in terms of cultures. These are some of the areas of your research that you must tidy up. My answer is Yes! you can. However, your ecotoxicological model will be localized.
Is it possible to explain ecological risk assessment by monitoring of heavy metal from frog meat??
To a certain extent, you can.
When I was chief radiologist (1987) in the aftermath of the Chernobyl disaster, we determined the radionuclide content in the muscles of fish and frogs of the Pripyat River.
Thank you all for nice comments, actually i want to collect frog from tea garden aquatic system. I want to show wether there is Association among pesticide and heavy metals with aquatic impacts
A limitation for using frogs as indicator species for an aquatic ecosystem is that they absorb relatively small amounts of toxic compounds from the water: they have no gills (= low uptake from water) and their food is only partly aquatic (= limited food-chain uptake). Exposure of fish is higher in both ways, but they may be much more difficult to sample quantitatively.
It will be useful that you specify the heavy metal of interest. The heavy metals vary in their chemical properties hence vary in respect of the tissue they can be lodged as well as the physiological consequences of their presence in the tissue. However, recall that frogs are amphibians, that implies that, they may spend some of their life in water(aquatic) and on land (terrestrial). The above submissions would invariably make them not perfectly suitable for Risk Assessment in the environmental media they can inhabit.
É perfeitamente possível sim. Teoricamente temos a seguinte opção: Os anfíbios possuem hábito alimentar insetívoro, nesses caso, há uma proximidade com as macrófitas. As macrófitas são eficientes na absorção e acumulação de metais pesados, bem como, algumas macrófitas tem eficiente sistema de translocação de metais pesados da raiz para os caules e folhas. Portanto, os insetos herbívoros seriam indicadores de segunda ordem e dessa maneira os sapos podem ser indicadores indiretos de metais pesados. Contudo, fica a importância de registra o metal migrando na cadeia alimentar.
A dificuldade será que os anfíbios pode não se restringe exatamente a oferta alimentar desse complexo, portanto, será mais difícil do que encontrar concentrações em peixes. Mas a tentativa é válida sim, especialmente pelo caráter lipofílico e bioacumulador que os metais possuem nas células.
as per the method we use for ecological risk assessment, it is meant for sediments and the aquatic environment primarily.
It is assumed that the productivity of aquatic system depends on its sensitivity to the toxic. With this concept, the ecological risk for dust/soil/sediments was assessed by many researchers based on metal toxicity and its response back by the environment.
I think a benchmark study on the level of heavy metals around the study area as well as comparison with the level of heavy metals on that same size and species of frog from a pristine environment.
