  • The fate of arsenic in contaminated paddy soil with gypsum and ferrihydrite amendments

    Ferrihydrite and gypsum (CaSO4·2H2O) are two chemicals which were suggested to reduce the bioavailability of arsenic (As) in agricultural field. The efficiency of those chemicals added in the paddy field was investigated by pot culture in this study. The results showed As uptake by rice under ferrihydrite treatment was significantly ...

  • Arsenic Removal

    The Arsenic Removal ProcessArsenic, a naturally occurring element, is found throughout the environment; for most people, food is the major source of exposure. Acute (short-term) high-level inhalation exposure to arsenic dust or fumes has resulted in gastrointestinal effects (nausea, diarrhea, abdominal pain); central and peripheral nervous system disorders have occurred in workers acutely ...


  • A Trace of Arsenic

    The cans of baby formula invaded Brian Jackson’s Dartmouth College lab late in 2010. His team picked up an armful of popular brands at the food co-op in Hanover, N.H. Then another armload. Eventually Jackson had a cabinet full of the brightly labeled canisters. Today, he still keeps a few in his office. Not as clutter — that’s not his style. He just likes to keep his toxicology ...

  • Properties and Behavior of Inorganics in Contaminated Soil

    Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment ...

  • Human health risk assessment of an arsenic contaminated golf course

    St Michael’s Jubilee Golf Course in Widnes was constructed between 1964 and 1986, by re-grading chemical waste deposits generated from local industries, which were then covered with a thin layer of topsoil and grassed over.  An estimated 4.5 million tonnes of waste materials are present beneath the golf course.  The site is underlain by alluvium and a major aquifer, the Sherwood ...

  • Effect of amendment on phytoextraction of arsenic by Vetiveria Zizanioides from soil

    Abstract: The present study was undertaken to evaluate the growth response of Vetiveria zizanioides amended with organic amendments to arsenic (As) in contaminated soils and its ability to sequester As. The test results indicate that the plants exhibited high tolerance to As in the soils and their normal growth continued even though As concentration reached 500 mg/kg. However, when As ...

  • Arsenic concentrations in irrigation water, soil and selected vegetables in Bangladesh

    The effect of Arsenic (As) concentration in irrigation water on As accumulation in six selected vegetables grown during the dry season (December-May) in Bangladesh has been assessed. Three field sites were selected for the assessment, which included two As affected areas (Chandpur and Narayanganj) and one unaffected area (Bogra). The As concentrations in edible parts of the selected vegetables ...

  • Arsenic biotransference to alfalfa (Medicago sativa)

    The arsenic (As) concentration in the edible part of crops depends on the availability of the As present in the soil and the ability of a crop to take up As and translocate it to the target organs. The aim of this study was the determination of As concentration in soils and alfalfa (Medicago sativa) in field conditions and pot experiments to analyse As soil–forage transference. Results show that ...

  • Influence of phosphate and citric acid on the phytoextraction of As from contaminated soils

    The influence of phytoextraction in arsenic (As) contaminated soil on the phosphate and citric acid addition were investigated using Pteris vittata L. (Chinese brake fern). The As uptake in the fronds increased 85% in As–spiked soil when phosphate was added. The addition of citric acid for 2 weeks to the phosphate added soils resulted in the highest As uptake by 75% compared to only ...

  • Airport Lead and Arsenic Removal - Case Study

    City of Cincinnati The Airport was built on a former military firing range and apple orchard. To complete the removal of all the lead and arsenic, we excavated and removed over 20,000 tons of treated and non-treated contaminated soil. Then we stabilized 11,000 tons of hazardous soil on site. We graded and capped the site all while complying with FAA, City and Airport ...

  • The investigation of arsenic and heavy metal concentrations in soil, water and crops around abandoned metal mines

    Soils, water and crops around abandoned metal mines can be contaminated by heavy metals from adjacent tailings and waste rocks accumulated during mining operations. The results indicate that the As, Zn, Cd, and Cr concentrations exceed the soil contamination standard in many soil samples of the nearby farmlands as well as the tailings sites. In the case of water quality, the As concentrations in ...

  • Growth response and tolerance of Job's tears (Coix lacryma-jobi L) to arsenic in spiked soils

    Job's tears (Coix lacryma-jobi L.), a perennial herbaceous plant, was cultured in soils spiked by arsenic. The results show that Job's tears rapidly grows with high biomass and strongly tolerates with normal accumulation for As in lightly or moderately spiked soils. It insensitively responds to As changes when the content of As in soils is less than 40 mg kg−1 while the concentration of As in ...

  • Effect of arsenic on soil, plant and foodstuffs by using irrigated groundwater and pond water from Nadia district, West Bengal

    The total arsenic withdrawn by the seven shallow tubewells used for agricultural irrigation in the arsenic-affected areas of Nadia district per year is 3851 g (mean: 550 g, range: 118?2410 g). When the amount of arsenic in the groundwater is high, it has been observed that the levels of arsenic in agricultural land soil and plants are correspondingly high. Arsenic concentration in paddy field ...

  • Accumulation and toxicity of monophenyl arsenicals in rat endothelial cells

    Clark 1 (diphenylarsine chloride) and Clark 2 (diphenylarsine cyanide) were used as chemical weapon agents (CWA), and the soil contamination by these CWA and their degraded products, diphenyl and phenyl arsenicals, has been one of the most serious environmental issues. In a series of comparisons in toxicity between trivalent and pentavalent arsenicals we investigated differences in the ...

  • Thermal Remediation of Karst Limestone – Redstone Arsenal, Alabama

    Abstract: Electrical resistance heating (ERH) was used for the thermal remediation of two sites at Redstone Arsenal (RSA) near Huntsville, Alabama. Both sites feature karst limestone with heavy clay overburden. The two sites are located about five miles (10 km) apart, but differ considerably in the characteristics of the limestone. At site RSA-053, the heavy clay is underlain by very hard, ...

  • Determination of arsenic in baby foods and fruit juices by GFAAS

    The United States does not have specific regulations specifying the allowable levels of toxic elements in foods, but many other countries do. For example, Canada has a specific tolerance level for arsenic of 0.1 ppm in ready to serve fruit juices, nectars, and beverages1. The toxic nature of arsenic is such that chronic exposure to the element can lead to internal cancers of the bladder and ...

  • Pteris multifida Poir., a new arsenic hyperaccumulator: characteristics and potential

    This paper reports a new arsenic hyperaccumulator, Pteris multifida Poir, a fern that grows widely in the southeast of China. The results show that the average arsenic content in the fronds was 1144.78 mg/kg, with a highest value of 2061 mg/kg. The average arsenic content in the roots was 692.7 mg/kg, and the average bioconcentration factor was 1.2, with a highest value of 1.78. The average ...

  • Filtronics Electromedia® Removes Arsenic From 150 ppb to Below 3 ppb

    Arizona State Highways 85 and 86 meet in Pima County in southwestern Arizona. The intersection used to form a “Y” and gave birth to a town name. The unusual name comes from a state law that required town names have three letters, so “Y” became Why. What’s not so unusual is that the town of Why, like many Arizona communities, has high levels of arsenic in their well ...
