  • 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 ...

  • How to Deal with Arsenic in Drinking Water

    Thanks to recent developments in technology, daily drinking water undergoes a rigorous treatment process for water to be consumable. This is because most ground and natural river waters have a chemical in them called arsenic. Arsenic is a metallic chemical element that is found commonly among rocks and sulfur in the Earth’s crust. Arsenic is known for getting into your drinking water from ...

  • Arsenic from community water fluoridation: quantifying the effect

    Community water fluoridation is a WHO recommended strategy to prevent dental carries. One debated concern is that hydrofluorosilicic acid, used to fluoridate water, contains arsenic and poses a health risk. This study was undertaken to determine if fluoridation contributes to arsenic in drinking water, to estimate the amount of additional arsenic associated with fluoridation, and compare this ...

  • 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 ...

Do not panic, though. Simply research an arsenic filtration system. There are many advanced methods that can be used to remove arsenic from water. Arsenic in water removal is completely affordable and safe. ...

  • Determinants of the use of alternatives to arsenic-contaminated shallow groundwater: an exploratory study in rural West Bengal, India

    Shallow groundwater containing toxic concentrations of arsenic is the primary source of drinking water for millions of households in rural West Bengal, India. Often, this water also contains unpleasant levels of iron and non-negligible fecal contamination. Alternatives to shallow groundwater are increasingly available, including government-built deep tubewells, water purchased from independent ...

  • Minimizing Arsenic Leaching from Water Treatment Process Residuals

    Ferric chloride addition was investigated for treatment of As-laden spent regeneration brine from ion exchange processes. Furthermore, varying conditions and calcium addition were investigated for the stabilization of the resulting As-laden solids. Arsenic, sulfate, bicarbonate, and chloride concentrations in the spent brine (300 mg/L, 605 mg/L, 305 mg/L, and 24 g/L, respectively) were orders of ...

  • A novel approach to determine a resin's sorption characteristics for the removal of natural organic matter and arsenic from groundwater

    The objective of this work was to study the sorption behavior of the strongly basic and macroporous commercial resin IRA 958-Cl for the removal of natural organic matter (NOM) from groundwater in the Melenci settlement located near Zrenjanin (Northern Serbia). The investigation was performed in a pilot plant using native groundwater and the same water after chlorination with sodium hypochlorite. ...

  • Park City, Utah Arsenic removal from ground water

    Background Park City Utah Water, which serves a population of 6,500, has five water sources. Spiro Tunnel and Spiro Portal are two that were in need of Iron and Manganese removal as well as above limits for Arsenic. Filtronics was engaged by the engineering firm of Eckhoff, Watson and Preator (EWP), Salt Lake City, to perform pilot tests for the Park City Municipal Corporation. The ...

  • Reasons You Should Invest in an Arsenic Water Treatment System

    In many areas of the U.S., the element arsenic makes its way into the water supply. This element can have adverse health effects. Although it’s rare that it shows up in large enough concentrations to be fatal, it can still cause problems and should be eliminated. Health Effects Many studies have been done to determine the specific effects of consuming water ...

  • San Joaquin Valley California - Arsenic removal from ground water

    Background The San Joaquin Valley of California is approximately 220 miles long and varies in width to a maximum distance of approximately 80 miles. The occurrence of groundwater over the entire extent of the valley is abundant. Recharge for the varied depths of aquifers is from precipitation in the form of rain and the snow pack from the western Sierra Nevada Mountain Range. High ...

  • How Installing Arsenic Drinking Water Treatment Can Save Your Life

    Arsenic is an element so associated with its toxicity and harmful effects on the human body that the word itself is often used for any kind of general poison. While the exact ways that exposure to the metalloid attacks various organs and systems is still not fully understood, studies throughout the scientific community are continually determining that ingesting arsenic through drinking water can ...

  • Life cycle analysis of two Hungarian drinking water arsenic removal technologies

    Determining a technology's merit as a solution to Hungarian drinking water arsenic contamination goes beyond technical concerns: environmental and economic aspects also play very important roles. In an effort to address the current arsenic drinking water requirements in Hungary, life cycle analysis (LCA) methodology was applied on two example arsenic removal technologies, ...

  • Reasons You Should Invest in an Arsenic Water Treatment System - Case study

    In many areas of the U.S., the element arsenic makes its way into the water supply. This element can have adverse health effects. Although it’s rare that it shows up in large enough concentrations to be fatal, it can still cause problems and should be eliminated. ...

  • Slow arsenic poisoning of the contaminated groundwater users

    This paper gives impact of Arsenic contaminated water on human health as well as overview of the extent and severity of groundwater arsenic contamination in Bangladesh. Scalp hair is the most important part of the human body to monitor the accumulation of this type of poison. Therefore, an experiment has been carried out by Neutron Activation Analysis (NAA) at Atomic Energy Research Establishment ...

  • Subsurface iron and arsenic removal: low-cost technology for community-based water supply in Bangladesh

    The principle of subsurface or in situ iron and arsenic removal is that aerated water is periodically injected into an anoxic aquifer through a tube well, displacing groundwater containing Fe(II). An oxidation zone is created around the tube well where Fe(II) is oxidised. The freshly formed iron hydroxide surfaces provide new sorption sites for soluble Fe(II) and arsenic. The system's efficiency ...

  • What You Should Know about Arsenic Treatments

    The nutrients that you put into your body directly impact your health. If you consume water with harmful substances, bacteria, or metalloids, it could create serious issues. While not a metal, arsenic is considered a metalloid because it contains many of the same properties as metallic elements. Typically found in soil, arsenic is harmful when ingested. Unfortunately, many Americans unknowingly ...

  • Arsenic geochemistry in a biostimulated aquifer: An aqueous speciation study

    Stimulating microbial growth through the use of acetate injection wells at the former uranium mill site in Rifle, Colorado, USA, has been shown to decrease dissolved uranium (VI) concentrations through bacterial reduction to immobile uranium (IV). Bioreduction also changed the redox chemistry of site groundwater, altering the mobility of several other redox‐sensitive elements present in the ...
