The Importance of Selenium Speciation

Got Selenium?The topic of selenium has garnered attention in various industries for decades now, but the challenge associated with removing selenium from wastewaters has not diminished. In order to understand the most effective form of treatment for this unusual element that is both an essential micronutrient but also toxic at relatively low concentrations, the molecular form, or speciation, of selenium must be understood.

The two most common inorganic forms present in industrial wastewaters and agricultural runoff are selenite and selenate. Numerous treatment options are available for selenite, but conventional…

Arsenic and Lead in Fruit Juice

Child Drinking Fruit JuiceEveryone knows that too much of a good thing can be bad. But what happens when even a little of a good thing can be harmful?  Consumer reports tested different fruit juices for cadmium, lead, mercury, and inorganic arsenic. The results were startling.  Click here for a detailed description of the juices tested and potential health risks.

Choosing the Appropriate Method for Arsenic Speciation

When routine analytical testing indicates that a sample contains elevated levels of arsenic, more detailed characterization is often warranted. Performing arsenic speciation analysis – where specific molecular forms of arsenic are individually quantified – is often critical; however, if you don’t select the most appropriate analytical method, you can end up without the data you need or paying too much for data that is not helpful. But with dozens of potential arsenic species and numerous analytical options available, deciding what analyses to request can sometimes seem overwhelming. Brooks…
