  • Ultra-trace arsenic speciation at Columbia Analytical

    Ultra-trace speciation of arsenic and other metals is performed using a variety of techniques tailored to the specific combination of species, matrix, and detection limits required. Currently, two analytical systems are applied: Ion Chromatography-Inductively Coupled Mass Spectrometry (IC-ICP-MS) and Hydride Generation-Cryogenic Gas Chromatography-Flame Atomic Absorption Spectrometry ...


  • Harmful Effects of Arsenic on Human Health

    Arsenic can pose a serious risk to your health. It is very important to detect any traces of it and have it removed from your water as soon as possible. Detecting any potential arsenic contamination in your water can ensure that you have a fresh, trustworthy supply to drink from. If you don’t, these are some of the health risks you could experience. Skin Changes ...

  • Distribution of atmospheric trace elements and assesment of air quality in Argentina employing the lichen, Ramalina celastri, as a passive biomonitor: detection of air pollution emission sources

    Ramalina celastri was used as a passive biomonitor to study the relationship between elemental accumulation, emission sources and physiochemical parameters used as air pollution biomarkers in Argentina. The concentration of 27 elements was determined in the thalli by Neutron Activation Analysis (NAA). The content of photosynthetic pigments, peroxidation products, water and sulphur was determined ...

  • The 5 Benefits of Professional Arsenic Removal from Water

    It is a sad and scary truth, but many homes have arsenic in their water systems. High levels of arsenic can be dangerous to you, your family, your pets, and the property you inhabit. 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. ...

  • 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 ...

  • 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 ...

  • Arsenic and antimony speciation analysis in the environment using hyphenated techniques to inductively coupled plasma mass spectrometry: a review

    Elemental speciation involves the separation and quantification of different oxidation states or chemical forms of a particular trace element. Trace metals exhibit widely different toxicities depending on their elemental species in the environment. On the other hand, inductively coupled plasma mass spectrometry (ICP-MS) is considered to be the method of choice for elemental analysis for several ...

  • Project profile - Brandywine Elementary School New Palestine, Indiana AD26 arsenic, iron, manganese removal system

    Background In July 2009, AdEdge Technologies Inc. (AdEdge) was contacted by Ladd Engineering, Inc. to provide a proposal for the Brandywine Elementary School in the Southern Hancock School District. Shortly thereafter, AdEdge was selected to provide a potable water treatment system to the school to reduce elevated levels of arsenic, iron, and manganese that exceeded drinking water ...

  • Reclaimed Water Aquifer Storage and Recovery: Potential Changes in Water Quality

    Aquifer storage recovery (ASR) operations recharge and recover water through the same well or wells, creating a “bubble” of stored water that typically mixes minimally with ambient groundwater once the storage zone has been developed. Because ASR recharge water does not flow through a vadose zone and is not drawn through an aquifer to a distant point of withdrawal, changes in water quality that ...

  • Pharmaceuticals in water fact sheet

    Recent events have led to a growing concern regarding trace pharmaceutical compounds found in drinking supplies across the United States. While pharmaceuticals have been detected in amounts far below the levels considered harmful to humans and there is no evidence demonstrating these pharmaceuticals pose a significant health risk to humans, we understand many consumers will want to protect their ...

    Potentially  toxic   elements   in   European   soils mapped by researchers. A new study has mapped levels of chemical elements found in Europe a aoricultTal soils. In most places, unusually high concentrations are linked t geology, such as high levels of arsenic in the Massif Central in France. Huma.. activity is to blame in some small areas, for ...

  • Our drinking water systems are a disaster. What can we do?

    In the wake of the Flint, communities turn to innovative technology and financing to prevent the next crisis. People in developed countries turn on the tap and safe drinking water flows, a dramatic health benefit they tend to take for granted. That complacency was dramatically disrupted last year when children in Flint, Michigan, started testing positive for lead poisoning and the ...
