ARSENIC UPTAKE, DISTRIBUTION AND ACCUMULATION IN BEAN-PLANTS - HUMAN HEALTH RISK

The response of bean plants to different levels of arsenic (As) was in vestigated-the processes of uptake, distribution and accumulation of A s. Arsenic uptake depended on the As concentration in solution, and As content in the roots increased as the time of treatment increased. Th e most important finding was the high sensitivity of bean plants to ar senic. Salinity caused a reduction in arsenic uptake. Finally, it is i mportant to note that the As concentration in the bean fruit was not h armful for human consumption, although practically all the As absorbed was transported to the aerial part of the plants.
