Consequences of paddy cultivation in arsenic (As)-contaminated environment on crop growth, yield, and transmission to food chain through consumption of rice are known to all. Furthermore, the adverse consequences of As toxicity continues upon consumption of As rich rice by human, irrespective of gender and socioeconomic perspective, have been documented in large number of literature. In the current investigation, our prime objectives were to explore (a) As accumulation pattern in different rice varities cultivated in “As Hot – Spot area” located in “lower Indo – Gangetic Plane” for two successive years, and a least addressed issue (b) how rice grain quality traits get influenced by As contaminated environment. Findings from the current investigation suggest that (i) As content in irrigation water in the study sites were higher than the permissible limit mentioned by FAO; (ii) there is a season-wise, variety-wise, year-wise, as well as location-wise variation in As accumulation pattern noticed; and (iii) variation in grain quality attributes can also be seen. Results also suggest that grain As content were within the range of 0.242 ± 0.007 to 1.222 ± 0.005 mg As per kg. Statistical interpretation indicates that with fluctuation in grain As content significant modulation in grain quality traits like grain weight, head rice recovery % in downward fashion can be observed. Beside these, with variation in grain As content an increase in gel consistency, cooking time, and amylose content were also noted.
