Water pollution throughout the world is affecting food chains and food webs. Water such as lakes, rivers, streams, creeks, and oceans become polluted in many different ways. One main way is the dumping of trash, or littering. Many creeks, rivers, and even oceans have been polluted by manmade items such as trash (EPA, 2011). When fresh water such as rivers and creeks become polluted, it hurts the surrounding wildlife.

A practical definition of water pollution is: "Water pollution is the addition of substances or energy forms that directly or indirectly alter the nature of the water body in such a manner that negatively affects its legitimate uses".[1]: 6 Water is typically referred to as polluted when it is impaired by anthropogenic contaminants. Due to these contaminants, it either no longer supports a certain human use, such as drinking water, or undergoes a marked shift in its ability to support its biotic communities, such as fish.
"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.
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.
2. Indroduction
Water pollution occurs when harmful substances are released
into the water in large quantities which cause damage to
people, wildlife, or habitat or indirectly into water bodies
without proper treatment to remove harmful compounds.
3.
4. Effects of water pollution
Water pollution is a major problem
in the global context. It has been
suggested that it is the leading
worldwide cause of deaths and
diseases, and that it accounts for
the deaths of more than 14,000
people daily.
An estimated 700 million Indians
have no access to a proper toilet,
and 1,000 Indian children die of
diarrhea sickness every day.
Some 90% of China's cities suffer
from some degree of water
pollution, and nearly 500 million
people lack access to safe drinking
water.
5. In addition to the acute problems of water pollution in
developing countries, industrialized countries continue to
struggle with pollution problems as well.
In the most recent national report on water quality in the United States,
a. 45 percent of assessed stream miles,
b. 47 percent of assessed lake acres, and
c. 32 percent of assessed bay were classified as polluted
6. Ground Water Pollution
Interactions between
groundwater and
surface water are
complex.
Consequently,
groundwater pollution is
not as easily classified
as surface water
pollution.
7. Purification of water
Purification of water
involves physical,
biological and chemical
processes such as:-
1.Filtration
2.Sedimentation
3.Chlorination
4.Slow sand filters
5.Activated Sludge
6.Flocculation
8. Physical processes
Filtration is a
mechanical or physical
operation which is used
for the separation of
solids from fluids
(liquids or gases) by
interposing a medium
through which only the
fluid can pass.
9. Sedimentation is the
tendency for particles in
suspension or
molecules in solution to
settle out of the fluid in
which they are
entrained, and come to
rest against a wall.
10. Biological processes
Slow sand filters are
used in water
purification for treating
raw water to produce a
potable product. They
are typically 1 to 2
metres deep, can be
rectangular or
cylindrical in cross
section and are used
primarily to treat
surface water.
11. Activated sludge is a process dealing with
the treatment of sewage and industrial
wastewaters and developed around 1912-
1914.Atmospheric air or pure oxygen is
introduced to a mixture of primary treated or
screened sewage (or industrial wastewater)
combined with organisms to develop a
biological floc which reduces the organic
content of the sewage.
12.
13. Chemical process
Flocculation is, in the field of chemistry, a
process where colloids come out of
suspension in the form of floc or flakes. The
action differs from precipitation in that, prior
to flocculation, colloids are merely suspended
in a liquid and not actually dissolved in a
solution.
14. Chlorination is the process of adding the
element chlorine to water as a method of
water purification to make it fit for human
consumption as drinking water. Water which
has been treated with chlorine is effective in
preventing the spread of water born disease.
15. Chemical & other contaminants
Inorganic water pollutants include:-
Acidity caused by industrial discharges
(especially sulphur dioxide from power plants)
Ammonia from food processing waste
Chemical waste as industrial by-products
Fertilizers containing nutrients--nitrates and
phosphates--which are found in storm water
run off from agriculture, as well as commercial
and residential use
16. Heavy metals from motor vehicles (via
urban storm water runoff) and acid mine
drainage
Silt (sediment) in runoff from construction
sites, logging, slash and burn practices or
land clearing sites
17. Macroscopic pollution—large visible items polluting
the water—may be termed "floatables" in an urban
storm water context, or marine debris when found
on the open seas, and can include such items as:
Trash: (e.g. paper, plastic, or food waste) discarded
by people on the ground, and that are washed by
rainfall into storm drains and eventually discharged
into surface waters
Nurdles: small ubiquitous waterborne plastic pellets
Shipwrecks: large derelict ships.
18. Pathogens are another type of pollution that prove
very harmful. They can cause many illnesses that
range from typhoid and dysentery to minor
respiratory and skin diseases. Pathogens include
such organisms as bacteria, viruses, and protozoan.
These pollutants enter waterways through untreated
sewage, storm drains, septic tanks, runoff from
farms, and particularly boats that dump sewage.
19.
20. The most polluted river in United Kingdom
The pollution of rivers and streams with chemical
contaminants has become one of the most curtail
environmental problems within the 20th century.
Waterborne chemical pollution entering rivers and
streams cause tremendous amounts of
destruction.

22. Additional forms of water pollution
Three last forms of water pollution exist
in the forms of petroleum, radioactive
substances, and heat. Petroleum often
pollutes waterbodies in the form of oil,
resulting from oil spills.
23. Thermal Pollution
Thermal pollution is the rise or fall in the temperature of
a natural body of water caused by human influence.
A common cause of thermal pollution is the use of water
as a coolant by power plants and industrial
manufacturers
Elevated water temperatures decreases oxygen levels
(which can kill fish) and affects ecosystem composition
Thermal pollution can also be caused by the release of
very cold water from the base of reservoirs into warmer
rivers.
24.
25. What are the possible solutions of water
pollution?
Industrial effort : Industry is responsible for a large
amount of pollutants including ones that pollute water.
Legislation has been passed forcing
industry to make efforts to clean up their
waste. Through reducing the waste that
they produce, it has been possible to
reduce the amount of pollutants that enter
the water cycle .
26. Municipal treatment plants are designed to
control conventional pollutants: BOD and
suspended solids
Well-designed and operated systems (i.e.,
secondary treatment or better) can remove 90
percent or more of these pollutants.
Some plants have additional sub-systems to
treat nutrients and pathogens. Most municipal
plants are not designed to treat toxic
pollutants found in industrial wastewater
27. Measurement of water pollution
Water pollution may be analyzed
through several broad categories of
methods: physical, chemical and
biological. Most involve collection of
samples, followed by specialized
analytical tests. Some methods may be
conducted without sampling, such as
temperature
28. Farming Solutions
Choosing organic options can help to reduce the amount of
water pollution. These items are grown without the use of
chemicals.
Those chemicals, when used, enter the water cycle.
Organic products don't introduce those chemicals to the water
cycle.
29. Caring about waste
By properly disposing of all waste, you can help to reduce the
amount of water pollution that is created
The proper management of mass waste disposal
can help to control the introduction of pollutants
into the water cycle.
Simple steps like not storing waste by running
water and controlling runoff in areas where waste
is stored can help to reduce the amount of
pollution introduced into the water cycle
30. Stopping the cycle
There are ways to interrupt the natural
water cycle and prevent pollution
In some places simply filtering water before allowing it
to continue its natural flow may be sufficient .
A natural and beautiful method of doing this is being
used in many places. They are called rain gardens.
They are specifically designed with plants that will
absorb water that otherwise would have runoff into
waterways. This measure also stops contaminants
that may have been washed into those waterways.
