  • 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 ...

  • Linking trace element variations with macronutrients and major cations in marine mussels Mytilus edulis and Perna viridis

    Marine mussels have long been used as biomonitors of contamination of trace elements, but little is known whether variation in tissue trace elements is significantly associated with those of macronutrients and major cations. Here, we examined the variability of macronutrients and major cations and their potential relationships with bioaccumulation of trace elements. We analyzed the ...

  • Sulfur Compounds Analyzer MEXA-1170SX

    The MEXA-1170SX is a continuous gas analyzer for sulfur compounds existing in engine emissions. It can measure SO2 concentration and the amount of total reduced sulfur compounds (TRS), such as H2S, separately. It can also measure the total sulfur compounds (TS) that contains both gaseous compounds and liquid compounds in PM, such as SO3. By utilizing ultra-violet fluorescence (UVF) method and ...

  • Sequential Extraction Procedure

    Sequential extraction is an analytical process that chemically leaches metals out of soil, sediment and sludge samples. The purpose of sequential “selective” extraction is to mimic the release of the selective metals into solution under various environmental conditions. One commonly used sequential extraction procedure is designed to partition different trace metals based on their ...
