Metal toxicity depends on the dose, route of exposure, and chemical species. The heavy metals associated with metal toxicity have a higher density than water. Metals that are found to be the most toxic are arsenic, cadmium, chromium, lead, and mercury. Specifically humans can accumulate metals through gastrointestinal absorption, inhalation of airborne toxicants, skin absorption, and direct deposition into tissues.

peer review: Did you get the information in the last sentence from a source? If so you just need to add the citation. I like how you added that the toxicity depends on the dose and route of exposure, as that is what we have been discussing in class.

In a study done by the National University of Comahue in Nuequen, Argentina on Rhinella arenarum on acute toxicity of arsenic. They concluded there are drastic adverse effects during their early developmental stage and high concentrations of the metal are required to elicit mortality. The exposure to arsenic alters the oxidative metabolism of toad embryos shown in the decrease of the total antioxidant capacity.

peer review: I would move the citation to the end of this paragraph since all of the information comes from the study explained by the source. I would also add more information on the organism the study was done on. Where you said it has adverse affects during their early development, I would add the early development of what organism.
