  • 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 ...

  • 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 ...

  • Accumulation kinetics of arsenic in Daphnia magna under different phosphorus and food density regimes

    In the present study, the dissolved uptake, dietary assimilation, and elimination of arsenic (initially added as arsenate) in the freshwater cladoceran Daphnia magna were examined. A biphasic correlation between the arsenic uptake rate and its ambient concentration, as well as a two–saturation‐site arsenic uptake competition with phosphate was observed. The calculated uptake rate constant, as ...

  • Arsenic biotransference to alfalfa (Medicago sativa)

    The arsenic (As) concentration in the edible part of crops depends on the availability of the As present in the soil and the ability of a crop to take up As and translocate it to the target organs. The aim of this study was the determination of As concentration in soils and alfalfa (Medicago sativa) in field conditions and pot experiments to analyse As soil–forage transference. Results show that ...

  • Solutions for removing arsenic from drinking water

    Arsenic, a metalloid element, is found in many naturally occurring compounds. In its inorganic form, arsenic is toxic. Arsenic occurs naturally in some groundwater supplies worldwide, including in the drinking water supplies in parts of Taiwan, Japan, Bangladesh, and western South America. This is causing health problems, according to the American Cancer Society. Albuquerque, New Mexico, is the ...

Arsenic in water removal is completely affordable and safe. ...

  • Guest editorial: the IRIS assessment of inorganic arsenic: is science being hijacked?

    The arsenic IRIS assessment exemplifies the current administration’s unwillingness to walk its own talk on transparency and scientific integrity. Early in her role as the EPA Administrator, Lisa P. Jackson expressed her now familiar mantra that regulatory initiatives must be “transparent” and risk assessments must be conducted to “ensure the highest levels of scientific ...

  • 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 ...

  • Adsorption of arsenic from drinking water using natural orange waste: kinetics and fluidized bed column studies

    The biosorption potential of orange waste (OW) was investigated using synthetic solutions of arsenic and contaminated drinking water under different parameters, e.g. biosorbent dose, initial concentrations of solution, contact time, and pH in a batch system. The optimum conditions were identified as a contact time of 30 minutes, pH 6, biosorbent dose of 1 g L−1, and initial arsenic ...
