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.
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 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.

3. POLLUTION & POLLUTANTS
• The Contamination of air, water and Soil with
the substances, which have adverse effect on
Living things, is Called Pollution.
• Those substances who polluted these areas
are called Pollutants.
• Pollutants are of many types including:
Gaseous Pollutants, Liquid Pollutants, Solid
Pollutants.
6. CARBON MONOXIDE
• A gas that comes from the burning of fossil fuels,
mostly in cars.
• It cannot be seen or smelled.
• Undetectable to the human senses
• SYMPTOMS
• Dizziness
• chest pain
• difficulty thinking
• convulsions
• Coma etc.
7. CARBON MONO-OXIDE(CO)
• Sources:
• Incomplete Combustion of Carbon Containing Fuels
used in Automobile Engines and defective furnaces.
• Smoke obtained by engines of cars, Buses, Aeroplanes
etc.
• Coal, wood and Oil burns and give black smoke having
CO
• Cigarette Smoke also contain CO
• Incomplete Combustion of agriculture and slush matter
• Industrial furnace (Blast furnaces)
8. CARBON MONO-OXIDE(CO)
• Toxic Effects on Human Beings & Animals
• CO inhaled then Carboxyhaemoglobin HbCO formed
Hb + CO HbCO
O2 availability reduced to the body cells (anoxia)
Suffocation and may even lead to death.
• So the Smokers daily inhale CO and produced HbCO in
their body and as a result normal body functions
9. EFFECTS OF (CO) POISIONING
• Effects: Carbon monoxide makes it hard for body parts
to get the oxygen they need to run correctly.
• Cardiovascular system is affected
• Adverse effects on nervous system
• Inflammatory response is initiated
• Hypoxia at the cellular level
• Death of cells and damage to major organs
• Elderly people with heart disease are hospitalized
more often when they are exposed to higher amounts
of carbon monoxide
10. NITROGEN OXIDES
• Nitrogen dioxide:
• A reddish-brown gas that comes from the burning of fossil fuels.
• It has a strong smell at high levels.
• Sources:
• Nitrogen dioxide mostly comes from power plants and cars.
• Agriculture.
• Transportation.
• Industry.
• Nitrogen dioxide is formed in two ways—when nitrogen in the fuel
is burned
• when nitrogen in the air reacts with oxygen at very high
temperatures
11. NITROGEN OXIDES
Effects
• Nitrogen dioxide exposure can give people coughs
• sweating
• unusual tiredness or weakness
• can make them feel short of breath. People who are
exposed to nitrogen dioxide have respiratory
infections.
• In plants can injure leaves and reduce growth
• Nitrogen dioxide reacts in the atmosphere to form acid
rain, which can harm plants and animals.
12.
13.
14. CARBON DIOXIDE
• It is also a pollutant, when generated in large
quantity - because it can reduce the oxygen
concentration in the air.
• It is a gas produced when fuel is burnt in
adequate oxygen.
• Normally, the atmospheric air will have 0.03%
CO2. When its concentration increases due to
pollution, it reduces the percentage of oxygen in
atmosphere.
15. CARBON DIOXIDE
• Effects:
• Global warming
• It disturbs buffering system
• Respiratory problems
• Acidosis in blood
• It can retard plant growth
16. SULPHUR DIOXIDE
• A corrosive gas that cannot be seen or smelled at low
levels but can have a “rotten egg” smell at high levels.
• Sources:
• Natural source is volcanoes.
• Sulfur dioxide mostly comes from the burning of coal
or oil in power plants.
• It also comes from factories that make chemicals,
paper, or fuel.
• Like nitrogen dioxide, sulfur dioxide reacts in the
atmosphere to form acid rain and particles.
17. SULPHUR DIOXIDE
• Effects:
• Sulphur dioxide exposure can affect people who have
asthma or emphysema by making it more difficult for
them to breathe
• It can also irritate people's eyes, noses, and throats.
• Sulfur dioxide can harm trees and crops
• High concentrations of SO2 can cause inflammation
and irritation of the respiratory system, particularly
during heavy physical activity.
• This gas can also react with other chemicals in the air
and convert to a small particle that can lodge in the
lungs and cause similar health effects.
18.
19. AMMONIA(NH3)
• Ammonia is a colorless, pungent gas
composed of Nitrogen and Hydrogen.
SOURCES
• Agriculture Biggest Source
• Livestock forming and animal waste account
for the biggest percentage of total ammonia
emissions which are due to decompositions of
Urea from large animal wastes
• Uric acid from poultry wastes
20. NH3 Sources
• Fertilizers applications
• Vegetation
• Biomass Burning
• Oceans
• EFFECTS
• Exposure to high concentration of gaseous ammonia in
the air results in lung damage.
21. Ammonia gas
• In many industries, ammonia gas (NH3) is used as
reducing agent.
• It is a corrosive gas with a high potentiality of causing
throat irritations,
• burning of pharynx, esophagus, etc.
• It can also cause digestive problems - when excess gas
is inhaled.
23. GREENHOUSE GASES
• Gases that stay in the air for a long time and
warm up the planet by trapping sunlight. This is
called the “greenhouse effect” because the gases
act like the glass in a greenhouse.
• Some of the important greenhouse gases are
• carbon dioxide,
• methane,
• nitrous oxide.
24.
25. GREENHOUSE GASES
Sources of green house gas
• Carbon dioxide is the most important greenhouse
gas. It comes from the burning of fossil fuels in
cars, power plants, houses, and industry.
• Methane is released during the processing of
fossil fuels, and also comes from natural sources
like cows and rice paddies.
• Nitrous oxide comes from industrial sources and
decaying plants.
26. GREENHOUSE GASES
• EFFECTS:
• Changes in the climate of the planet.
• Some of these changes might include
• More temperature extremes
• Higher sea levels
• Changes in forest composition
• Damage to land near the coast.
• Human health might be affected by diseases that are
related to temperature or by damage to land and water.
27.
28. SMOG
• Word Smog come from the blend of two words
“smoke” and “fog”
• Smog can formed in any climate where there is
lot of air pollution
CAUSES
• Volcanic eruption emits high level of SO2
• Burning of Fossil Fuels
• Pollution from vehicles and Industries
• Manufacturing of Chemicals
31. SMOG
HEALTH HAZARDS
• Burning in eyes
• Irritated Throat
• Breathing Difficulties
• Long Term exposure can cause cancer and death
SOLUTIONS
• Decreased by limiting those processes that create it…
• Develop cars that produce less smog
• Restrict usage of Dangerous products such as house
paints, Kitchen cleaners etc.
32.
33. PARTICULATE MATTER
• Solid and liquid matter i.e. suspended in the air
• Less than 0.1mm wide
• Small as 0.00005mm
SOURCES
• Particulate matter can be divided into two types
• 1) Coarse Particles 2) Fine Particles
• Coarse particles are formed from sources like road
dust, sea spray and Construction
• Fine particles are formed in Automobile Fuel
combustion and Power plants
34. EFFECTS OF PARTICULATE MATTER
• Small enough particles can enter the
lungs and cause health problems
• Asthma attacks
• Respiratory Problems
• Premature Death
36. CATALYTIC CONVERTER
• A catalytic converter is an emissions control device that
converts toxic pollutants in exhaust gas to less toxic
pollutants by catalyzing a redox reaction (oxidation or
reduction).
Two-way
A two-way (or "oxidation") catalytic
converter has two simultaneous
tasks:
1. Oxidation of carbon
monoxide to carbon dioxide:
2CO + O2 → 2CO2
2. Oxidation of hydrocarbons
(unburned and partially burned
fuel) to carbon dioxide and water.
Three-way
1. Reduction of nitrogen oxides
to nitrogen and oxygen: 2NOx →
xO2 + N2
2. Oxidation of carbon monoxide to
carbon dioxide: 2CO + O2 → 2CO2
3. Oxidation of unburnt hydrocarbons
(HC) to carbon dioxide and water
38. STRATIFIED CHARGED ENGINES
• A stratified charge engine is a type
of internal combustion engine,
used in automobiles, in which the
fuel is injected into the cylinder just
before ignition.
• This allows for higher compression
ratios without "knock," and
leaner air/fuel ratio than in
conventional internal combustion
engines.
• This produces a homogeneous
charge: a homogeneous mixture of
air and fuel, which is ignited by
a spark plug at a predetermined
moment near the top of
the compression stroke.
39. FABRIC FILTERS
• A baghouse (BH, B/H), bag filter (BF) or fabric
filter (FF) is an air pollution control device that
removes particulates out of air or gas released
from commercial processes or combustion for
electricity generation.
• Power plants, steel mills, pharmaceutical
producers, food manufacturers, chemical
producers and other industrial companies often
use baghouses to control emission of air
pollutants.
41. ELECTROSTATIC PRECIPITATOR AND
WET SCRUBBER
• An electrostatic precipitator (ESP) is a filtration
device that removes fine particles, like dust and
smoke, from a flowing gas using the force of an
induced electrostatic charge minimally impeding
the flow of gases through the unit.
• In contrast to wet scrubbers which apply energy
directly to the flowing fluid medium, an ESP
applies energy only to the particulate matter
being collected and therefore is very efficient in
its consumption of energy (in the form of
electricity).
