بیشترArsenic and antimony display similar geochemical behaviour in the environment and are usually associated in mining areas, where sulphide ores are exploited. The most common As mineral is arsenopyrite (Goldschmidt 1954 ); however, arsenic commonly occurs in pyrite, galena, chalcopyrite, and, to a lesser extent, in sphalerite.

بیشترArsenic, atomic number 33 lies in between phosphorus and antimony in group 15, the so called Nitrogen group of the periodic table. Members of the group including of course nitrogen, along with arsenic, phosphorous, antimony and bismuth are particularly stable in compounds because they tend to form double or triple covalent bonds.

بیشترFoods produced on soils impacted by antimony (Sb) mining activities are a potential health risk due to plant uptake of the contaminant metalloids (Sb) and arsenic (As). Here we report for the first time the chemical speciation of Sb in soil and porewater of flooded paddy soil, impacted by active Sb mining, and its effect on uptake and speciation …
بیشترAntimony (Sb) is a toxic metalloid, and its pollution has become a global environmental problem as a result of its extensive use and corresponding Sb-mining activities.The toxicity and mobility of Sb strongly depend on its chemical speciation.In this review, we summarize the current knowledge on the biogeochemical processes …
بیشترA chemico-toxicological similarity between arsenic and antimony exists and their toxicology is often seen. Indeed, both elements possess several common properties, e.g. they are clastogenic but not mutagenic in the trivalent state and they have a carcinogenic potential: trivalent arsenicals are known to be human carcinogens and …

بیشتر3.2. The Effect of Humic Acid on the Removal of Aqueous Antimony and Arsenic. Figure 2 a,b showed the impact of HA on K 2 FeO 4 removing As. It could be seen that compared with zero dosage, the addition of K 2 FeO 4 had no significant effect on the removal rate of As, which was less than 4% for both circumstances.
بیشترBloody diarrhea. Eventually it may lead to shock, seizure, coma and death. Luckily this kind of poisoning is rare. It could occur through intentional poisoning, or maybe through occupational exposure, but many more people are affected by arsenic poisoning at much lower levels, and over longer periods of time.
