Scholarcy highlights

  • Chronic renal failure, in the main agricultural region under reservoir based cascade irrigation in Sri Lanka has reached crisis proportion
  • Over 5,000 patients in the region are under treatment for CRF
  • The objective of this study is to establish the etiology of the CRF
  • Concentrations of nine heavy metals were determined in sediments, soils of reservoir peripheries, water and Nelumbo nucifera grown in five major reservoirs that supply irrigation water
  • The CRF prevalent in north central Sri Lanka is a result of chronic dietary intake of Cd, supported by high natural levels of fluoride in drinking water, coupled with neglecting of routine de-silting of reservoirs for the past 20 years
  • Paper presented at the seminar on Impact of Agriculture on Sri Lankan Environment and remedial measurers by the integration of IK with modern technology, Kandy, Sri Lanka
