| Popis: | Arsenic contamination of groundwater has been reported in over 20 countries worldwide where tens of millions of people are being exposed to excessive levels of arsenic in their drinking water, especially in countries of the Asian region, Bangladesh in particular. This study focusses on analytical techniques currently used for the estimation and speciation of arsenic in aqueous phase (soil and water) and in plant tissues; the uptake of arsenic by two commonly used vegetable crops (amaranth and silverbeet) using solution culture and pot culture studies; speciation-toxicity relationship of arsenic to plants; the nature of arsenic species in plant tissue and Bangladesh groundwater samples; and the effect of iron (Fe) on arsenic (As) uptake by plants and animals.
