ABSTRACT
Arsenic (As) contamination in both groundwater and rice grain is a wide ranged health hazard in south Asian countries especially in West Bengal, India. Rice being the staple food is a proficient method of As intake into human body. The study involves cooking of sunned and parboiled variety of rice cultivar Minikit and Ranjit with five different As contaminated waters (<3, 32, 45, 67 and 104 µg/l). Result shows a unidirectional flow of As from rice to water. The raw rice As concentration is high in parboiled one than in the sunned grains irrespective of the cultivars. The reduction rate of As in cooked rice from raw rice grain is inversely proportional to increasing As concentration in cooking water and the gruel As content is directly proportional with cooking water As concentration.
