Exactly what is the analytical problem and what is the minimum analytical information needed to provide a reasonable answer In this connection it is well to categorize the type of analysis desired oxyhalides in drinking water, arsenic speciation in drinking water, speciation of chromium in plating baths, etc. 

The major portion of absorbed inorganic and organic arsenic is cleared very rapidly from blood in other words, arsenic levels in blood are elevated only for a very short time after absorption. However, if a steady exposure occurs - as is the case of exposure through drinking water - arsenic levels in blood can reach a steady state and thus reflect the degree of exposure (Vahter...

Deep tubewells (>150-200 m depth), mainly in the southern coastal region, and wells in older Plio-Pleistocene sediments from the Barind and Madhupur Tracts of northern Bangladesh almost invariably have arsenic concentrations below 5 xgL and usually less than 0.5 xgL (BGS and DPHE, 2001). It is fortunate that Calcutta and Dhaka draw their water from these older sediments and do not have drinking-water arsenic problems. Dhaka is sited at the southern tip of the Madhupur Tract (Figure 5). Shallow open dug wells also generally have low arsenic concentrations, usually <10 xgL (BGS and DPHE, 2001).
