Abstract

|
|
1) For tile micro-analysis of mercury in plant materials, the method of Furutani was shown to be the simplest and most efficient way and the recovery of the assay was about 98%.
2) When the rice grain was soaked in 1/1000 diluted solution of organo-mercury fungicide for 8 hours at the end of March, the amounts of mercury residues in the brown rice and unhulled ripe were 8.8 to 9.5 ㎍/g seeds and 10.1 to 10.7 ㎍/g seeds, respectively.
3) By washing the treated rice seeds with running water for three days, the residual mercury concentration was reduced to 1/4 to 1/5; thus the mercury residues were 1.86 to 1.92 ㎍/g for brown rice and 1.86 to 2.93 ㎍/g for unhulled rice.
4) The residual mercury was present more in the unhulled rice than in the brown rice, either before or after washing of the treated seeds.
5) Among the different rice varieties. no difference was observed in mercury residues by seed treatment and washing.
