Predicting Arsenic Behavior in the Wastewater of Mouteh Gold Plant by Geochemical Modeling
Arsenic is one of the heavy metals and nearly all its compounds, especially organic compounds, are toxic. The wide spectrum of diseases caused by this element has led to evaluation of the toxicity of different arsenic species and identification of the major natural and anthropogenic pollution sources of it in the nature. Mining activities are among the main sources of anthropogenic pollution of...
متن کاملMetabolic adaptations to arsenic-induced oxidative stress in Isatis cappadocica. Naser Karimi* and Zahra Souri
Arsenic is considered as one of the most important environmental contaminant elements. Some plant species can grow in arsenic contaminated soils and they are able to reduce arsenic toxicity. In this study, a hydroponic experiment was conducted on Isatis cappadocica, a newly-discovered As hyperaccumulator. Accordingly, we conducted this experiment to compare the interaction of effect of arsenic ...
متن کاملStudies of In-Vitro Amlodipine and Arsenic Displacement Interaction at Binding Sites of Bovine Serum Albumin
In this study, the binding of amlodipine (a Ca ++ channel Blocker) and arsenic (metalloid) to bovine serum albumin (BSA) was studied by equilibrium dialysis(ED) method in order to have an insight into their binding chemistry to BSA. Free amlodipine concentration was increased due to addition of arsenic which reduced the binding of the compounds to BSA. However, the free fraction was not increa...
متن کاملArsenic and inorganic arsenic compounds
Arsenic, arsenic trioxide and pentoxide, arsenous acids, arsenic acid and their salts (arsenites and arsenates) are carcinogenic substances (Carcinogen category 1) and do not, therefore, have MAK and BAT values (Greim 2002). The former TRK value (technical exposure limit) for arsenic and its inorganic compounds was 0.10 mg arsenic/m (measured as the inhalable fraction of the aerosol; calculated...
متن کاملArsenic-Based Antineoplastic Drugs and Their Mechanisms of Action
Arsenic-based compounds have become accepted agents for cancer therapy providing high rates of remission of some cancers such as acute promyelocytic leukemia (APL). The mechanisms by which arsenic-containing compounds kill cells and reasons for selective killing of only certain types of cancer cells such as APLs have recently been delineated. This knowledge was gained in parallel with increasin...
متن کاملA case of cirrhosis and primary carcinoma of the liver in chronic industrial arsenical intoxication.
Arsenical poisoning may occur in industry, in three forms: (I) From inhalation of or contact with dust of inorganic compounds, (2) from inhalation of arseniuretted hydrogen, (3) from contact with organic arsenic compounds. The inorganic compounds act as local irritants to the skin and mucosa and may have a carcinogenic effect. Arseniuretted hydrogen acts as a haemolytic agent and organic arseni...
