EVALUATION OF DIFFERENT PLANTS AS ARSENIC ACCUMULATOR FROM CONTAMINATED SOIL

Abstract

Three pot experiment were conducted at the 1-lorticultural farm, Sher-e-Bangia Agricultural University, Dhaka, Bangladesh to mitigate arsenic from soil using trap plant from contaminated soil during the period from July 2012 to October 2012 followings Completely Randomized Design (CR!)) with three replications. Rice, arum and fern (Pteris vittala L.) were used in the three different experiment, respectively and each of the experiment soil was treated with defferent arsenic concentration viz. As0, Control: As500. 500 ppm; As10 , 1000 ppm; As20 . 2000 ppm of arsenic were exploited. Fern (Pieris vittata L.) can survive with a very high concentration of arsenic in soil and accumulate 23837.2. 15332.6 and 17007.1 ppm arsenic when soil treated with 2000, 1000 and 500 ppm arsenic, respectively. Whereas rice straw acumulated 206.3, 194.9, and 82.9 ppm arsenic. rice grain accumulated 61.6. 36.5, and 29.9 ppm arsenic. arum leaves acuumulated 973.5. 751.7 and 422.3 ppm arsenic and arum runner accumulated 210.4, 202.3 and 178.8 ppm arsenic when soil treated with 2000. 1000 and 500 ppm arsenic. respectively. Using P/ens vittata L. as a trap plant is a possible way to mitigate arsenic from soil vhich can keep away of arsenic pollution in food chain.
