  • 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 ...

  • Arsenic Exposure and Childhood CancerA Systematic Review of the Literature

    The literature on environmental arsenic exposure and childhood cancer risk comprises 1) studies seeking childhood cancers among arsenic-exposed populations, 2) studies seeking arsenic exposure among childhood cancer cases, and 3) studies seeking associations in populations with both arsenic exposures and childhood cancer cases. No skin cancers were found in dermal examinations of over 25,000 ...

  • Inequitable allocation of deep community wells for reducing arsenic exposure in Bangladesh

    Community wells that extend deeper than most private wells are crucial for reducing exposure to groundwater arsenic (As) in rural Bangladesh. This study evaluates the impact on access to safe drinking water of 915 such intermediate (90–150 m) and deep (>150 m) wells across a 180 km2 area where a total of 48,790 tubewells were tested with field kits in 2012–13. Half the shallow private wells ...

  • Winter exposure assessment of copper, zinc and arsenic in drinking water of inhabitants in Beijing, China

    Human exposure to Cu, Zn and As from drinking water in Beijing, China was estimated in winter. Cu, Zn and As were detected at 6.1, 400 and 0.6 µg/L on average in stagnant water, significantly different from those in the actually ingested boiled tap water, 5.1, 130 and 2.4 µg/L, respectively. Daily intake of Cu, Zn and As from drinking water was 0.8%, 7.7% and 28.5% of the minimum for adults ...

  • Arsenic and Bladder Cancer: Observations and Suggestions

    Arsenic from drinking water is a well-known risk factor for bladder cancer. The purpose of this paper is to systematize some important yet often overlooked facts considering the relationship between arsenic exposure and the occurrence of bladder cancer. Since the exposure to inorganic arsenic from food, inhaled air, and skin absorption as well as arsenic methylation ability are not fully ...

  • Executive Summary of Arsenic Contamination in the World

    Annex 1 is an ancillary summary database which provides supplementary material to Table 1 in the Executive Summary of Murcott:  Arsenic Contamination in the World: An International Sourcebook.  Table 1 is entitled Arsenic Contamination in the World  and summarizes the exposed populations, the current arsenic standards and the sources of arsenic for each of the 105 identified ...

  • 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 ...

  • Guide to Removing Arsenic from Drinking Water

    It’s said that the human body is made up of almost 60 percent water. Is the water you’re putting into your body pure? Many people are unaware of the chemicals and compounds that are seeping into their drinking water and wreaking havoc on their internal systems. Arsenic, for example, can be found in many different areas. In the Northeast especially, well water is more likely to be ...

  • The effectiveness of arsenic remediation from groundwater in a private home

    Abstract Private wells are the source of drinking water for approximately 15% of households in the United States, but these wells are not regulated or monitored by government agencies. The well waters can contain arsenic, a known carcinogen that occurs in groundwater throughout the nation at concentrations that can exceed the Maximum Contaminant Level defined by the U.S. Environmental ...

  • Bioaccumulation and oxidative stress in Daphnia magna exposed to arsenite and arsenate

    Arsenic pollution and its toxicity to aquatic organisms have attracted worldwide attention. The bioavailability and toxicity of arsenic are highly related to its speciation. The present study investigated the differences in bioaccumulation and oxidative stress responses in an aquatic organism, Daphnia magna, induced by 2 inorganic arsenic species (As(III) and As(V)). The bioaccumulation of ...

  • Removal of arsenic from an aqueous solution by pretreated waste tea fungal biomass

    Arsenic exists in natural waters both in inorganic and organic forms. The inorganic form of arsenic is more toxic compared to its organic form. Inorganic arsenic is the predominant form in contaminated groundwater. Arsenic exists in two,oxidation states: arsenite, As (III) and arsenate, As (V) (Pokhrel and Viraraghavan, 2006). It is introduced in the aqueous system through geochemical reactions ...

  • Speciation of five arsenic compounds in urine by HPLC/ICP-MS

    High-performance liquid chromatography (HPLC) coupled to an ICP-MS has become an invaluable analytical tool for the determinations of trace levels of individual arsenic compounds (speciation). Speciation of arsenic is used to improve our knowledge of arsenic’s biochemical interactions and to evaluate toxicity risks. The toxicity and bioavailability of arsenic is highly dependent on form or ...

  • Parental decisions, child health and valuation of avoiding arsenic in drinking water in rural Bangladesh

    Arsenic contamination of groundwater in Bangladesh is a widespread public health hazard. Water sources without high arsenic levels are scarce, affecting people's availability for work and other activities when they have to seek safe water to drink. While children are particularly susceptible to chronic arsenic exposure, limited information and heavy constraints on resources may preclude ...

  • Protective and antioxidant role of selenium on arsenic trioxide–induced oxidative stress and genotoxicity in the fish hepatoma cell line PLHC‐1

    In vitro models are useful tools for rapid screening for toxicity, elucidation of mechanisms of toxicity, and understanding complex interactions among environmental toxicants. These evaluations may provide useful information for ecological evaluations if the relationship between in vitro and in vivo effects is established. The present study was undertaken to evaluate the protective effect of ...

  • Potential for arsenic contamination of rice in Bangladesh: spatial analysis and mapping of high risk areas

    Knowledge of the location and severity of arsenic contamination in Bangladesh is required to develop land and resource management strategies to reduce human exposure to arsenic and arsenic contamination of food and water supplies. Potential high risk areas for arsenic contamination of rice were identified using spatial analysis and modelling. Existing country-wide data on groundwater arsenic ...

  • Acute toxicity of arsenic and oxidative stress responses in the embryonic development of the common South American toad Rhinella arenarum

    Arsenic, a natural element of ecological relevance, is found in natural water sources throughout Argentina in concentrations between 0.01 and 15 mg/L. The autochthonous toad Rhinella arenarum was selected to study the acute toxicity of As and the biochemical responses elicited by the exposure to As in water during its embryonic development. The LC50 value averaged 24.3 mg/L As and remained ...

  • Mode of Action and Growth Toxicity of Arsenic to Tilapia Oreochromis mossambicus Can Be Determined Bioenergetically

    Abstract  We present a bioenergetics-based approach to analyze the chronic effects and growth toxicity mode of action in tilapia Oreochromis mossambicus exposed to waterborne As and to predict fish growth under different exposure scenarios. 7-day exposure bioassays showed that tilapia accumulate As when exposed to waterborne As. We conducted growth bioassays to assess chronic As toxicity to ...
