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...

In this study, arsenic concentration and hazard quotient (HQ) in eight species of marine fish in Khuzestan province including Epinephelus coioides, Acanthopagrus latus, Platycephalus indicus, Cynoglossus arel, Pampus argenteus, Tenualosa ilisha, Liza macrolepis and Liza klunzingeri were studied. This research was conducted in 2020. 15 fish were prepared from any of the different or fish landing...
Arsenic is considered as one of the most important environmental contaminant compound. Some plant species can grow in arsenic contaminated soil and they are able to reduce arsenic toxicity. Nowadays, phytoremediation as a new and friendly environmental technique employs the use of plants to remediate contaminated soil. Previous studies showed that Isatis cappadocica is an arsenic hyperaccumulat...
Arsenic toxicokinetics are important for disease risks in exposed populations, but genetic determinants are not fully understood. We examined urine arsenic species patterns measured by HPLC-ICPMS among 2189 Strong Heart Study participants 18 years of age and older with data on ~400 genome-wide microsatellite markers spaced ~10 cM and arsenic speciation (683 participants from Arizona, 684 from O...
Epidemiological studies have indicated that exposure of humans to inorganic arsenic in drinking water is associated with the occurrence of bladder cancer. The mechanisms by which arsenic induces this malignancy are still uncertain; however, arsenic metabolites are suspected to play a pivotal role. The aim of the present study was the investigation of uptake capabilities of human urothelial cell...
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 ...
Urinary arsenic species have been determined for approximately 3000 urine samples obtained from residents of a community surrounding an arsenic-emitting copper smelter. Levels of inorganic, monomethylated and dimethylated arsenic species ranged from less than 1 microgram/L (the instrumental detection limit) to 180 micrograms/L seen for dimethyl arsenic. Comparison of a subsample of this populat...
Arsenic contamination of drinking water poses serious health risks to millions of people worldwide. Current technologies used to clean arsenic-contaminated water have significant drawbacks, such as high cost and generation of large volumes of toxic waste. In this study, we investigated the potential of using recently identified arsenic-hyperaccumulating ferns to remove arsenic from drinking wat...
Arsenic trioxide has been successfully used as a therapeutic in the treatment of acute promyelocytic leukemia (APL). Detailed monitoring of the therapeutic arsenic and its metabolites in various accessible specimens of APL patients can contribute to improving treatment efficacy and minimizing arsenic-induced side effects. This article focuses on the determination of arsenic species in saliva sa...
