The demand for autonomous sensors for unattended, continuous nutrient monitoring in
water is rapidly growing with the increasing need for more frequent and widespread …

The recent discovery that phytochelatins are important for arsenic (As) detoxification in
terrestrial plants results in the necessity to understand As speciation and metabolism in plant …

A modified molybdenum blue method for fast and accurate measurement of arsenate and
phosphate in aqueous solution at concentrations below 10μmoll− 1 is reported. The …

The use of a novel inexpensive photometric device, a paired emitter–detector diode (PEDD)
has been applied to the colorimetric determination of phosphate using the malachite green …

The speciation of P in environmental samples is operationally defined, since it depends on
the analytical method used. In this study, we compared four methods to measure P in …

Although the role of iron in marine productivity has received a great deal of attention, no iron
storage protein has been isolated from a marine microorganism previously. We describe an …

In this study, a simple and sensitive method for the determination of arsenic in water
samples was developed. The method is based on the formation of micro particles of Ethyl …

Arsenate [As (V)] is taken up by phosphate [P (V)] transporters in the plasma membrane of
roots cells, but the translocation of As from roots to shoots is not well understood. Two …

Accurate, high-resolution profiles of nitrate and phosphate distributions in the open ocean
are difficult to obtain using conventional techniques. Concentrations typically range from low …

Arsenic is common toxic contaminant, but tracking its mobility through submerged soils is
difficult because microscale processes dictate its speciation and affinity to minerals …
