Phytoremediation uses plants to remove, detoxify, or immobilize environmental pollutants like metals and organic compounds from soil and water. It works through natural processes of plants like absorption, accumulation, precipitation, volatilization, and stimulation of degrading microbes. Common mechanisms include phytoextraction, phytostabilization, phytotransformation, phytostimulation, and rhizofiltration. While cost-effective and environmentally friendly, phytoremediation is slow and not suitable for highly contaminated sites. Plant species are chosen based on their ability to uptake and process contaminants as well as adapt to soil and climate conditions.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
2. Phytoremediation
• Phyto (Greek Word) it means “Plant”, Remediare (Latin Word) it means “to
remedy”. Phytoremediation means, remedy through plants.
• Phytoremediation can be defined as “the efficient use of plants to remove,
detoxify or immobilize environmental contaminants in a growth matrix (soil,
water or sediments) through the natural biological, chemical or physical
activities and processes of the plants”
2
5. Phytoextraction
• The uptake of contaminants by
plant roots and movement of these
contaminants from roots to the
above part of plants .
• Contaminant permanently removed
from soil.
5
6. Phyto stabilization
• It refers to the immobilization of
contaminants in the soil through:
absorption and accumulation by
roots.
• The mobility of the contaminant is
reduced, migration to groundwater
is prevented and thus bioavailability
of metal into food chain is reduced.
6
7. Phyto transformation
• Also known as phytodegradation, it
is the breakdown of contaminants
taken up plants by metabolic
processes within the plant.
• Remediate some organic
contaminants, such as chlorinated
solvents and herbicides.
7
8. Phyto stimulation
• Breakdown of contaminants within
the plant root zone, or rhizosphere.
• Carried out by bacteria or other
microorganisms flourishing in the
rhizosphere.
• Microbes in rhizosphere transform
contaminant to non toxic product.
• Works well in the removal of
petroleum hydrocarbons
8
9. Phytovolatilization
• Involves plants taking up
contaminants from soil,
transforming them into volatile
forms and transpiring them into
atmosphere.
• Works on organic compounds and
heavy metal and mercury is the
primary metal contaminant that
this process has been used for.
9
10. Rhizofiltration
• Adsorption or precipitation onto
plant roots or absorption of
contaminants in the solution
surrounding the root zone.
• Compared to phytoextraction, here
the plants are used to address the
groundwater rather than soil.
10
11. Time
The time depends on:
• Type and number of plants used
• Type and amount of harmful chemicals
present
• Size and depth of polluted area
• Type of soil and conditions present
Often, it takes many years to clean up a site
with phytoremediation.
11
13. Types of plant used
• Plant species are selected for use based on factors such as:
• Ability to extract or degrade the contaminants of concern
• Adaptation to local climates
• High biomass
• Depth root structure
• Compatibility with soils
• Growth rate
13
14. Examples of plants used in phytoremediation
Indian mustard
(Brassica juncea
L.)
Brassicaceae
species are
really useful
to accumulate
certain metals
Sunflower
(Helianthus
Annuus L.)
one month old
plants reached the
incredible goal of
removing more than
95% of uranium in
24 hours
lemongrass
(Cymbopogon citratus
(D.C.) Stapf.)
Based on translocation
factor, lemongrass acted as
potential phytostabilizer and
was found efficient in
translocation of Al, Zn, Cd,
Pb, Cr, As and Ni from roots
to shoot.

15. Why should we used phytoremediation and
why should not!
Advantages
• Suited to remediation of large areas of soil
• Cost effective compared to conventional
methods
• Easy to implement and maintain and also
accepted by public
• Fewer spread of contaminants via air and
water
• Environmentally friendly and aesthetically
pleasing to public
Disadvantages
• Limited to shallow ground water, soil and
sediments
• Not as effective for sites with high
contamination
• Slower than conventional methods
• Contaminants may mobilized into ground
water
• Disposal of contaminants accumulated in
plants after harvesting-pollution again!
