Tissue- and Region-Specific Accumulation of Arsenic

Arsenic is identified as a known carcinogen and ubiquitously exists in nature. It appears that accumulation of inorganic arsenic (iAs) and its methylated metabolites in various tissues is closely correlated with the long-term toxicity and carcinogenicity of this metalloid. In this study, various ars

Accumulation of arsenic by aquatic plants

1991-4-15  Accumulation of arsenic from pool water reached a steady state in 2-6 days, depending on the external arsenic concentration. At steady state, either uptake and loss of arsenic are equal or the sites for arsenic uptake are saturated.

2011-8-26  Accumulation of Arsenic by Synechocysis. The accumulation of arsenic in the algal cells was investigated. Figure 2 indicates the concentration change of arsenic in the alga when exposed to different arsenate or arsenite concentration. During a 2-week incubation period, the concentrations of As in alga increased significantly with increasing external As concentration.

Accumulation of Arsenic in Drinking Water

2019-5-25  The arsenic content of these solids ranged from 10 to 13 650 μg of As/g of solid (as high as 1.37 wt %), and the major element of most solids was iron. Significant amounts of arsenic were even found in solids from systems that were exposed to relatively low

Accumulation of arsenic in tissues of rice plant (Oryza

2007-10-1  A study was conducted to investigate the accumulation and distribution of arsenic in different fractions of rice grain (Oryza sativa L.) collected from arsenic affected area of Bangladesh. The agricultural soil of study area has become highly contaminated with arsenic due to the excessive use of arsenic-rich underground water (0.070 ± 0.006 mg l −1,n = 6) for irrigation.

Biotransformation and Accumulation of Arsenic in Soil

2003-1-31  These arsenic species are relatively nontoxic to humans; however, in the environment they may accumulate in the soil and decompose to more toxic arsenic species. The aim of this study was to determine the fate and biotransformation of these arsenosugars in soil using HPLC−ICP-MS analysis.
