Water Research, 1987In the new E.C. directive relating to the quality of water intended for human consumption the maximum admissable concentration of nitrate in drinking water is decreased from 22.6 mg N03 --N/l to 11.3 mg N03 --N/l. The guide level is 5.6 mg N03 --N/l (1). At the same time, in many European countries an increasing nitrate concentration in ground water is

By means of a newly-developed speciation technique an arsenic compound was identified as hexafluoroarsenate at high concentration (about 0.8mgl(-1) as As) in a lake polluted by ...
