How we are polluting environment
• Look at any ecosystem and there could be multiple forms of contamination—
streams full of toxic chemicals from industrial processes, rivers overloaded
with nutrients from farms, trash blowing away from landfills, city skies
covered in smog. Even landscapes that appear pristine can experience the
effects of pollution sources located hundreds or thousands of miles away.
• Pollution may muddy landscapes, poison soils and waterways, or kill plants
and animals. Humans are also regularly harmed by pollution. Long-term
exposure to air pollution, for example, can lead to chronic respiratory disease,
lung cancer and other diseases. Toxic chemicals that accumulate in top
predators can make some species unsafe to eat. More than one billion people
lack access to clean water and 2.4 billion don’t have adequate sanitation,
putting them at risk of contracting deadly diseases.

Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.
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.

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.
4. ENVIRONMENTAL POLLUTION
Environmental Pollution can be defined as any undesirable
change in physical, chemical, or biological characteristics of any
component of the environment i.e. air, water, soil which can cause
harmful effects on various forms of life or property.
Pollution: The term pollution can be defined as influence of any
substance causing nuisance, harmful effects, and uneasiness to
the organisms
Pollutant:- Any substance causing Nuisance or harmful effects or
uneasiness to the organisms, then that particular substance may
be called as the pollutant.
5. TYPES OF POLLUTION
WATER POLLUTION
AIR POLLUTION
LAND POLLUTION
NOISE POLLUTION
7. Water Pollution can be defined as alteration in
physical, chemical, or biological characteristics of
water through natural or human activities and
making it unsuitable for its designated use.
Fresh Water present on the earth surface is put to
many uses. It is used for drinking, domestic and
municipal
uses, agricultural, irrigation, industries, navigatio
n, recreation. The used water becomes
contaminated and is called waste water.
8. SOURCES OF WATER POLLUTION
Most of Water Pollution is man made It may also occur
naturally by addition of soil particles through erosion animal
wastes and leaching of minerals from rocks
The sources of water pollution can be classified as
Municipal WasteWater
Industrial Waste
Inorganic Pollutants
Organic Pollutants
Agricultural Wastes
Marine Pollution
Thermal pollution
10. INDUSTRIAL WASTE
The major source of water pollution is
the waste water discharged from
industries and commercial bodies, these
industries are
chemical, metallurgical, food processing
industries, textile, paper industries. They
discharge several organic and inorganic
pollutants. That prove highly toxic to
living beings.
11. INORGANIC POLLUTANTS
They include fine particles of different metals, chlorides,
sulphates, oxides of iron, cadmium, acids and alkalies.
12. ORGANIC POLLUTANTS
They Include oils, fats, phenols, organic acids grease and
several other organic compounds
13. MARINE POLLUTION
Ocean are the final sink of all natural and manmade
pollutants. Rivers discharge their pollutants into the sea.
The sewage and garbage of costal cities are also dumped
into the sea. The other sources include, discharge of oils,
grease, detergents, and radioactive wastes from ships.
14. THERMAL POLLUTION
Thermal Pollution of water is caused by the rise in
temperature of water. The main source of thermal pollution
are the thermal and nuclear power plants. The power
generating plants use water as coolants and release hot
water into the original source. Sudden rise in temperature
kills fish and other aquatic animals.
16. Air pollution is the introduction of
chemicals, particulate matter, or biological
materials that cause harm or discomfort to humans
or other living organisms, or cause damage to the
natural environment or built environment, into the
atmosphere.
A substance in the air that can cause harm to
humans and the environment is known as an air
pollutant.
17. CAUSES OF AIR POLLUTION
Carbon dioxide-this happens because of
Deforestation and fossil fuel burning.
Sulfur dioxide –Due to the burning of sulfur
containing compounds of fossil fuels.
Sulfur oxides- very dangerous to humans at a
high concentration. Sulfur in the atmosphere
is responsible for acid rain.
18. CONSEQUENCES OF AIR POLLUTION
CO2 is a good transmitter of sunlight, but it also
partially restricts infrared radiation going back
from the earth into space, which produces the so-
called greenhouse effect that prevents a drastic
cooling of the Earth during the night.
CO2 in atmosphere --> GLOBAL WARMING
19. Land pollution is the demolition of Earth's land
surfaces often caused by human activities and
their misuse of land resources. It occurs when
waste is not disposed properly.
Urbanization and industrialization are major
causes of land pollution.
20. CAUSES OF LAND POLLUTION
Four Main causes of land pollution:
Construction
Agriculture
Domestic waste
Industrial Waste
21. CONSTRUCTION
Buildings take up resources and land, the trees are
chopped down and used to make buildings.
Takes away the places for animals and other
organisms to live.
22. AGRICUL
TURE
As there are more and more people inhabiting the
earth, food is in higher demand and so forests are
chopped down and turned into farmland
In addition, herbicides, pesticides, artificial
fertilizers, animal manure are washed into the
soil and pollute it.
23. DOMESTIC WASTE
Tons of domestic waste is dumped every day. Some waste
from homes, offices and industries can be recycled or
burnt in incinerators .
There is still a lot of garbage, such as refrigerators and
washing machines that are dumped in landfills simply
because they cannot be reused in anyway, nor recycled .
24. INDUSTRIAL WASTE
Plastics factories, chemical plants, oil
refineries, nuclear waste disposal activity, large
animal farms, coal-fired power plants, metals
production factories and other heavy industry all
contribute to land pollution.
25. Noise pollution is excessive, displeasing
human, animal, or machine-created environmental
noise that disrupts the activity or balance of human
or animal life.
Sound becomes undesirable when it disturbs the
normal activities such as working, sleeping, and
during conversations.
World Health Organization stated that “Noise must
be recognized as a major threat to human well-
being”
26. SOURCES OF NOISE POLLUTION
Transportation systems are the main source of noise
pollution in urban areas.
Construction of buildings, highways, and streets cause a lot
of noise, due to the usage of air compressors, bulldozers,
loaders, dump trucks, and pavement breakers.
Industrial noise also adds to the already unfavorable
state of noise pollution.
Loud speakers, plumbing, boilers, generators, air
conditioners, fans, and vacuum cleaners add to the existing
noise pollution.
27. EFFECTS OF NOISE POLLUTION
According to the USEPA, there are direct links between
noise and health. Also, noise pollution adversely affects the
lives of millions of people.
Noise pollution can damage physiological and
psychological health.
High blood pressure, stress related illness, sleep disruption,
hearing loss, and productivity loss are the problems related
to noise pollution.
It can also cause memory loss, severe depression, and panic
attacks.
28. SOLUTIONS FOR NOISE POLLUTION
Planting bushes and trees in and around sound
generating sources is an effective solution for noise
pollution.
Regular servicing and tuning of automobiles can
effectively reduce the noise pollution
Social awareness programs should be taken up to educate
the public about the causes and effects of noise pollution.
Workers should be provided with equipments such as ear
plugs and earmuffs for hearing protection.
