What is Phytoremediation?
 Phytoremediation from Ancient Greek
 (phyto), meaning "plant",
 and Latin Remedium, meaning "restoring
balance"

History
 Basically Phytoremediation technique was first
introduced in 1983 but the concept was actually
implemented since last 300 years

Phytoremediation can be performed
following different methods:
1. PHYTOEXTRACTION
2. PHYTOSTABILIZATION
3. PHYTOVOLATILIZATION
4. PHYTOTRANSFORMATION
5. PHYTOSTIMULATION
6. RHIZOFILTERATION

Process dependence
 These processes totally rely on the ability of plants to
take up, accumulate or metabolize to less toxic
substances.

 The plant potential to uptake, accumulate and
degradation of contaminants vary from plant to plant.

Selection of plants
 The plants which are used in phytoremediation are
generally selected on the basis their growth rate and
biomass, their ability to accumulate and tolerate
contaminants, the depth of their root zone, and their
potential to transpire ground water
1/24/201

 The plants used in phytoremediation should be able to
degrade, accumulate or volatilize the contaminants,
and grow rapidly in wide range of different conditions

Advantages
 This technology has many advantages, beneficial in that
way because it is inexpensive, natural, conserves soil
resources and has no secondary contaminations and
enhances the soil quality and productivity

Other methods
 Ion exchange
 chemical precipitation
 reverse osmosis

Other methods
 These are the most helpful methods that have being
using to remove lead and cadmium (metal) and other
contaminations from wastewater.
 But these methods are very expensive and also they
produce a large amount of sludge requiring special
disposal, also decrease the fertility of soil leading to
infertile soil

PHYTOEXTRACTION
Phytoextraction:
Uptake and concentration of
pollutants from the
environment into the plant
biomass.

Phytoextraction
 Work well on metals (heavy metals) such as lead,
cadmium, copper, nikel
1/24/201

17

source
 source of these metals are industrial waste, mining
operation, smelting, combustion sources and solid
waste incinerators are the primary sources.
 Other sources include paint, batteries, metal plating,
automobiles exhausts, lead piping and fertilizers
pesticides

Phytoextraction
 for example lead and cadmium is soluble in water and
the excessive amount of lead and cadmium in water
cause many physiological and biochemical stress
symptoms in plants
1/24/201

Sargodha, Pakistan
19

Phytoextraction
 symptoms include such as growth reduction, disturbed
mineral nutrition, water imbalance.
 Like any other metal When they enter into the cell they
produce an oxidative stress in plant and lead to cell
damage

Phytoextraction
 Heavy metals also have serious effects on human health
cause many problems to human like are carcinogenic
increase the risk of cancer including liver cancer, skin
cancer, pulmonary damage

Phytoextraction
 lungs cancer, bladder, kidney, colon, nasal, paranasal
sinuses itai-itai disease, skeletal damage, also effect
metabolism, mental and intelligence problems,
Anaemia, pink disease, Neurasthenia, Diarrhea, high
blood pressure, nervous system disorders, vomiting,
fever, Multi-organ effect and also cause lead to death

Phytoextraction
 Plants used for treatment are as follows
 Water lettuce
 Sunflower
 Indian mustard
 Mostly these plants are used for treatment
1/24/201

 But also some other plant as well used
 Pteris vittata,
 Triticum aestivum,
 Brassica campestris,
 Brassica juncea
 Brassica Rapa
 Brassica napus, Salix sp., Populus sp.,
 Sanvitalia procumbens
 Sorghum Sudanese

Specificity
 For Arsenic, lead using the Sunflower (Helianthus
annuus)
 or the Chinese Brake fern (Pteris vittata) a
hyperaccumulator. Chinese Brake fern stores arsenic,
lead in its leaves.
 Salt-tolerant
(moderately halophytic) barley and/or sugar beets are
commonly used for the extraction of sodium
chloride (common salt) to reclaim fields that were
previously flooded by sea water.

Removal of substances
from soil or water with
release into the air.

Phytostimulation
Phytostimulation —
 This process is also known as rhizosphere degradation.
 Enhancement of soil microbial activity for the degradation of
contaminants, typically by organisms that associate with roots.

Phytostimulation

RHIZOFILTRATION
Rhizofiltration: Filtering
water through a mass of
roots to remove toxic
substances or excess
nutrients.

PHYTOSTABILIZATION
Reduction of mobility of
contaminants in
environment
1/24/201
7
Sargodha, Pakistan
36

PHYTOSTABILIZATION
 Stabilize the contaminants
 Prevent mechanical transportation of chemicals
 Trees transpire large quantities of water (even some
more than 15gal/day)
 So pumping action prevents contaminants from
migration into the water table
1/24/201

37

How stabilization occur
 Phytostabilization focuses on the long term stabilization
 For example, the plant's presence can reduce wind
erosion;
 or the plant's roots can prevent water erosion,
 In this way immobilize the pollutants by adsorption or
accumulation, and provide a zone around the roots
where the pollutant can precipitate and stabilize.
1/24/201

38

 Unlike phytoextraction, phytostabilization focuses
mainly on sequestering (attached) pollutants in soil near
the roots but not in plant tissues. Pollutants become
less bioavailable, and livestock, wildlife, and human
exposure is reduced.

Plant used
 Mostly tree species are used

Phytotransformation
Chemical modification of
the environmental
substances (contaminants)
takes place by plant.
1/24/201

Sargodha, Pakistan
41

Phytotransformation
 In the case of organic pollutants, such
as pesticides, explosives, solvents, industrial chemicals, and
other toxic substances are taken up by plants and transformed
into less toxic or non-toxic form when plant metabolize them.
1/24/201

Sargodha, Pakistan
42

Phytotransformation
 certain plants are used, such as Cannas, convert these
substances (contaminants) into non-toxic substances by their
metabolism.
 In other cases, microorganisms living in association with plant
roots may metabolize these substances in soil or water.
1/24/201

Sargodha, Pakistan
43

 These complex compounds cannot be broken down to basic
molecules (water, carbon-dioxide, etc.) by plants
 hence, the term phytotransformation represents a change in
chemical structure (less toxic) without complete breakdown of
the compound.

44

Phase I metabolism
 "Green Liver" is used to describe phytotransformation,
 as plants behave analogously to the human liver when
dealing with these xenobiotic compounds (foreign
compound/pollutant).
 After uptake of the xenobiotics, plant enzymes increase
the polarity of the xenobiotics by adding functional
groups such as hydroxyl groups (-OH).
1/24/201

Sargodha, Pakistan
45

Phase II metabolism
 In the second stage of phytotransformation, known as Phase II
metabolism,
 plant biomolecules such as glucose and amino acids are added
to the polarized xenobiotic to further increase the polarity
(known as conjugation).
1/24/201

Sargodha, Pakistan
46

Phase III metabolism
 In the final stage of phytotransformation (Phase III
metabolism),
 a sequestration (segregation) of the xenobiotic occurs within
the plant.
 The xenobiotics polymerize in a lignin-like manner and
develop a complex structure that is sequestered in the plant.
This ensures that the xenobiotic is safely stored, and does not
affect the functioning of the plant.

Disadvantages
 May take several years to remediate
 Consumption of contaminated plant tissue is also a
concern (may enter into food chain
 Possible effect on the food chain.

Conclusion
 So overall we have to understand their (mean
contaminants especially heavy metals) toxic effects on
living lives, on all living organisms (including animals,
humans and plants as well).
 Pakistan is an agricultural country and much of its
economy based on agriculture
 By using potential plants, curing this problem we can
increase yield and production in agriculture
 So in this way we can happy our farmers by overall
increasing yield production and also in this way we can
improve our economy and income
 And overall overcome economic losses
