Abstract:

Chronic Kidney Disease (CKD) prevailing in North Central Province of Sri Lanka is one of the major health issues of the country. Previous research findings revealed that nearly 10% of the people in NCP, Sri Lanka within the age group of 15 -70 years are affected by CKD. One strong argument is high cadmium (Cd) and arsenic (As) levels in drinking water, tank fish and edible aquatic rhizomes could be a possible reason for CKD. Several studies revealed that chemical fertilizers contribute immensely to elevate Cd, As levels and ionicity of water. This article outlines causative factors of CKD relevant to heavy metals and the ionicity of water with current fertilizer application practices in paddy farming of the NCP, Sri Lanka. Government of Sri Lanka provides a subsidy for chemical fertilizers especially for paddy farming. Hence over application of fertilizer is common in the region. Findings of several studies indicated that, Triple Super Phosphate (TSP), the principal source of P in paddy farming contain mean As and Cd levels of 31mg/kg and 2 mg/kg respectively. Even though, some initiatives were taken by the government to closely monitor the fertilizer distribution under subsidy scheme, soil test-based fertilizer application would be the most appropriate remedial measure to overcome this problem.
