This document summarizes various phytoremediation processes. Phytoremediation uses plants to remove contaminants from soil, water, or sediment. It includes processes like phytoextraction where plants absorb and concentrate contaminants, phytostabilization where plants reduce contaminant mobility and uptake, and phytotransformation where plants or associated microbes break down organic contaminants. Specific examples are given of plants used to remediate heavy metals like arsenic, cadmium, and lead through phytoextraction. Processes like rhizodegradation, phytovolatilization, and rhizofiltration are also outlined. The document notes advantages of phytoremediation being more environmentally friendly and cost effective
