migrant demographics
Where do they typically live?
Implications:
Rent and upkeep must be inexpensive to allow
for migrant population
How long do they usually stay in Beijing?
Implications:
Training process should be half a year or less
Community should facilitate frequent turn-over: Furniture exhange
market, Temporary furniture
Site should have convenient transportation to major transport hubs
Emotional support, networking, and mentoring for new arrivals

migrant demographics
What is their education level?
Where do they typically work?
Implications:
Government sponsored education to finish middle school
Retired workers could act as teachers in standard and vocational
training centers
Implications:
The Shougang community contains work in all sectors, allowing
residents to build off of their own skills and learn from their peers

Mechanics
Hydroponically raised
plants placed in contaminated water concentrate
the metals in their roots
and shoots
Contaminant migration
via wind, rain, and
grounwater prevented
through planting
Plants absorb elemental
metals from the soil and
biologically convert
them to gaseous metals
and release them into
the atmosphere
Roots absorb contaminants and store them in
above ground shoots
Pros
Cost effective for large
volumes; applicability to
many metals; less need
for chemicals; reduced
volume of secondary
waste; possibility of
recycling; appealing to
regulators and public
Less expensive; less
invasive; easy to implement; aesthetic value;
allows for the postponement of action
Minimal site disturbance; less erosion; no
need to dispose of
contaminated plants;
require little maintainence
Cost effective for large
areas; reduce in contaminant mass; metals
may be extracted from
plant material; metal
enriched plants may be
sold
Cons
Small, slow growing root
systems; the need to
specilized facilities and
expertise
Not appropriate for
highly contaminated
sites; does not remove
pollution; requires soil
additives
Less control over path of Slow process; cannot
contaminants; may
reach deep contaminacontaminate air
tion; must dispose of
plants
Affected Contaminants
Chromium, lead, zinc,
petroleum hydrocarbons, chlorinated
solvents, benzene,
ethylbenzene, xylenes
Lead, zinc, copper,
selenium, trichloroethelene, mercury, arsenic
Arsenic, Mercury, Selenium
Variety of solvents, Zinc,
nickel, cadmium, lead,
titanium, chromium
Plants
Water hyacinth, duckweed, pennywort
Grasses
Cattails, tabacco
Sunflower, indian mustard, Chinese brake fern
