RESEACH ABILITY TO ADSORB OF HEAVY METAL IN SOIL OF FERNS AND BROCCOLI
Researchers used vegetable processing contaminated soil heavy metals has brought many positive results. After studying the use of two plants are ferns, broccoli for processing heavy metals in soil Arsenic has achieved the following results: fern Pteris Vittata after 3 months of experiments, fern Pteris vittata there is resistance to additional land from 0 to 1500 mg/kg Asen. As accumulation capacity of ferns from 307 mg/kg ÷ 6042 mg/kg in the stems and roots are from 131 ÷ 3756 mg/kg. Broccoli has the ability to absorb and accumulate Asen fairly good. Past research shows that the roots accumulate more Asen in the body. Asen content in the roots of broccoli ranged from 39.4 ÷ 228.93 mg/kg.
