简介
Arsenic (As) pollution in soil and water has aroused a considerable attention. Inorganic forms of arsenic are associated with various cancers and cause major health problems. An experiment was conducted to investigate the effect of soil arsenic (As) concentration on arsenic and phosphorous accumulation in root, straw, husk and grain of rice ('Oryza sativa'). BRRI dhan 33 and BR11 rice varieties were planted on six levels of As-contaminated growth media (T1=3.2, T2=11.6, T3=18.7, T4=38.6, T5=57.8 and T6=80.3 ppm) in a Completely Randomized Design (CRD) with six replications. Accumulation of arsenic in root, straw, husk and rice grain significantly increased when As dose increased in soil media. It was observed that As was highly concentrated in the roots, whereas phosphorous was highest in the grain. The T6 treatment (80.3 ppm) showed the highest As accumulation in different plant tissues. Arsenic …
