Document Summary
March 27, 2017: need to clean up legacy pollution. Bioremediation: management of plant, microbial, fungal communities in contaminated environments to help immobilize, sequester, transform toxic substances. Instead of moving contaminated soil around use living organisms. Phytoremediation: phyto = using plants to remediate, start with contaminated media: In soil can have plants doing different things to two different groups of compounds. [1] organic contaminants: substances that can sometimes be broken down to form that"s less harmful, 2 ways for plants to deal with organic contaminants: [1] through roots: rhizofiltration, rhizodegradation, = plants either filter or degrade contaminants through the roots. [2] inorganic contaminants: = metals that can"t be broken down to compound that"s less toxic, 2 ways for plants to deal with inorganic contaminants. [1] through roots: rhizofiltration, plants can"t degrade contaminants, but can still filter through roots. [1] reduce mobility of contaminants through: drawing up water (not letting water go to groundwater)
