Phytoextraction of arsenic and boron and its effect on growth parameters of tagetes erecta l.

Tagetes erecta L. was used to explore the use of hydroponics technique for phytoremediation. The treatment of heavy metals such as Arsenic and Boron was provided to the plants of marigold. Various experiments conducted have shown the use of marigold as a plant species with hyperaccumulator capacity. In the present study the plants were given treatments of heavy metals for a period of 20 days. Growth analysis was carried out at the interval of 5 days and the data was recorded. This paper has focused on changes in the growth parameters in proportion to the heavy metal treatment provided. Here, hydroponics technique was used as an alternative to the soil media.
