Phytoremediation
by Caitlyn Clark
and Megan Baglien

Summary
What is phytoremediation?
How does it work?
How is it used?
Is it practical?
Modern Industry
Application classifications
Degradation: fosters microbial breakdown
Extraction: facilitates toxin movement into biomass
Containment: chemically bonds to contaminants to render them nonbioavailable or debilitating their mechanisms of motion

Who's On Board?
What is phytoremediation?
the process by which plants remove harmful chemicals from the soil through their roots
the chemicals can be stored within the plant, turned into harmless chemicals and stored, or turned into gases and released as the plant transpires
chemicals can also be held by the roots for bacteria to ingest and change
What toxins can phytoremediation be used for?
cadmium
uranium
acidic soil
strontium
high zinc concentrations
arsenic
aluminum in acidic soils
cesium-137
nitrates
pesticides
nickel
copper
pentachlorophenol
lead
selenium
petroleum hydrocarbon
Most toxins can be taken care of through phytoremediation in low or moderate concentrations. Pyhtoremediation depends on the kind of plants used. The plants must be able to thrive, but when the toxicity levels are too high for plant survival phytoremediation will not be successful. Also some forms of radiation may still be harmful once a plant has processed the toxins. In these cases the problem would worsen if the plant were to transpire the gaseous toxin.
Where and how is phytoremediation used?
Where
the United States, Canada, and much of Europe
rural and urban areas
municipal and industrial wastewater streams
military bases
How
cleaning up chemical spills
sequestering contaminants in wastewater
filtering water
cleaning up after nuclear disasters (Chernobyl)
in constructed wetlands
as vegetative caps
soil conditioning for agriculture
Phytoremediation
Pros
AND
Cons
low capital and operating costs
aesthetically pleasing
offers a permanent solution; no need for disposal sites
less disruptive to the environment
has potential to treat for multiple polutants
can take multiple seasons of tree growth before it works
sometimes the first group of trees needs to be replaced
its success depends on plant tolerance to the chemicals
plant choice and success is dependent on climate
Before
After
Wetland phytoremediation
Installation
Viable?
