    Arsenic, Antimony, and Bismuth Gallicchio - Major

    Antimony occurs in tri‐ (+3) and pentavalent (+5) compounds and is found in the earth's crust mostly associated with sulfur as stibnite and in ores associated with arsenic. Antimony is a group VA element of the periodic table and it has many of the same chemical and biological properties as the element arsenic. Stibine gas is odorless.

    Arsenic and antimony: comparative approach on

    28-11-1997· Arsenic and antimony share some chemical and toxicological properties 1, 2, 3. For instance, both metalloids act as clastogens but do not have mutagenic properties, their trivalent species are responsible for the mediation of their toxicological effects, and their biological half-lifes are relatively short in mammals, although there is evidence that certain parts are retained in the body for

    Arsenic and Antimony Transporters in Eukaryotes

    Arsenic and antimony are toxic metalloids, naturally present in the environment and all organisms have developed pathways for their detoxification. The most effective metalloid tolerance systems in eukaryotes include downregulation of metalloid uptake, efflux out of the cell, and complexation with phytochelatin or glutathione followed by sequestration into the vacuole.

    Mobilisation of Antimony and Arsenic Around

    Antimony (Sb) is an element similar to arsenic that forms anions in surface waters, rather than cations like other metals. Little is known about natural mobility of antimony in the environment. However, recent studies have suggested that antimony has similar toxicity to arsenic. Current New Zealand drinking water guideline values are 3 parts per billion...
