The document discusses adverse effects of oxygen demanding waste. It defines biochemical oxygen demand (BOD) as the amount of oxygen required by aerobic microorganisms to decompose organic matter in waste. High BOD levels can deplete oxygen in water bodies, harming aquatic life. The document outlines several factors that can contribute to high BOD, such as temperature increases promoting faster microbial growth, and eutrophication from excess nutrients causing algal blooms. Improper waste disposal such as littering and inadequate treatment of sewage and industrial runoff introduces oxygen-depleting organic matter into the environment.
Water quality is one of the most important factors in a healthy ecosystem. Clean water supports a diversity of plants and animals.
The quality of the water you consume or use in municipal or industrial processes must meet specific parameters to ensure that drinking water remains free from contaminants that could cause health issues.

Air pollution may come from anthropogenic or natural sources.
Water pollution is an appalling problem, powerful enough to lead the world on a path of destruction. Water is an easy solvent, enabling most pollutants to dissolve in it easily and contaminate it. The most basic effect of water pollution is directly suffered by the organisms and vegetation that survive in water, including amphibians. On a human level, several people die each day due to consumption of polluted and infected water.
Water Pollution
Water pollution occurs in many different forms, is produced in a variety of ways, and has a range of effects on the biological and physical environment. Consider some common examples:
A river dashing down a steep mountainside cuts into its rocky bed and carries away sand, silt, and pebbles. When the river reaches flat ground, it deposits these materials on the river bottom.
A farmer spreads herbicides, pesticides, and fertilizer on her land, knowing the increase in crop value this practice will produce. During the next rain, some of those chemicals are washed away into the nearest lake, where they remain suspended for weeks or months.
A small crack develops in an underwater pipe that carries oil from an offshore drilling rig to a holding tank on land. Crude oil seeps out of the crack and into the ocean, where marine plants and animals are exposed to its toxic effects.

"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.
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.
1. A SEMINAR ON:
ADVERSE EFFECT OF OXYGEN DEMANDING
WASTE
SUBMITTED BY:

2. INTRODUCTION
Any material which cannot be used in the form in
which it is produced is called a Waste.
It is no longer needed by us because it has lost its
value. If it is thrown around, it can cause soil, air or
water pollution. It also poses a serious threat to
normal life, plants, animals and human beings.
3. Definition….
The amount of oxygen absorbed by a sample of sewage
during a specific period, generally 5 days at a specific
temperature, generally 20° C for the aerobic destruction
of the organic matter by living organisms.
Total BOD is of more significance to food webs than
to water quality.
Oil spill:
An oil spill is the release of a liquid
petroleum hydrocarbons into the
environment due to human activity. And it is
a form of pollution
4. Cont….
Nitrates and phosphates in a body of water can
contribute to high BOD levels.
Nitrates and phosphates are plant nutrients and can
cause plant life and algae to grow quickly.
When plants grow quickly, they also die quickly.
This contributes to the organic waste in the water, which
is then decomposed by bacteria resulting in a high BOD
level.
5. Environmental significance
Principle test for biodegradability of any sample and strength of
the waste so measures the amount of pollution.
Important parameter to assess the pollution of surface and ground
waters where contamination occurred due to disposal of domestic
and industrial effluents.
Allows calculation of the effect of the discharges on the oxygen
resources of the receiving water.
Measurement of BOD in raw (influent) and treated (effluent)
wastewaters is a standard practice to evaluate treatment facility
performance.
Data from BOD tests used for the development of engineering
criteria for the design of wastewater treatment plants.
6. Cont….
Used in studies to measure the self-purification capacity of
streams
Serves regulatory authorities as a means of checking on the
quality of effluents discharged to stream waters.
One of the most important method in sanitary analysis to
determine the polluting power, or strength of sewage, industrial
wastes or polluted water.
It serves as a measure of the amount of clean diluting water
required for the successful disposal of sewage by dilution.
7. Factors affecting BOD…
Temperature
Elevated temperature decreases the level of DO of water
harming aquatic organisms like fish, amphibians and others
Increases the metabolic rate of aquatic animals and
enzyme activity, resulting in consumption of more food in a
shorter time
High temperature limits oxygen dispersion into deeper waters,
contributing to anaerobic conditions.
This can lead to increased bacterial levels when there is
ample food supply.
Higher water temperature increases plant growth rates
This results in a shorter lifespan and species overpopulation
causing an ”algae bloom” which reduces oxygen levels.
9. Eutrophication occurs due to oversupply of nutrients, which
causes explosive growth of plants and algae.
when such organisms die, consume the oxygen in the body of
water, thereby creating the state of hypoxia.
The primary limiting factor is phosphorus which promotes
excessive plant growth and decay, favouring simple algae and
plankton, and causes a severe reduction in water quality.
Phosphate adheres tightly to soil, so it is mainly transported by
erosion.
Once into the lakes, phosphate is extracted into water is slow,
hence the difficulty of reversing the effects of eutrophication
The source of this excess phosphate are detergents,
industrial/domestic run-off, and fertilizers.
CONT……
10. At higher levels of BOD….At high BOD levels, organisms such as macro
invertebrates that are more tolerant of lower dissolved
oxygen (i.e. leeches and sludge worms) may appear and
become numerous.
Organisms needing higher oxygen levels (i.e. caddisfly
larvae and mayfly nymphs) will NOT survive.
11. It is produced when oxygen dissolved in water reacts
with pyritic materials found in association with most
coal deposits. AMD degrades the water quality of
stream and supplies often to the point of eliminating all
biological activity within the stream contaminated with
AMD.
12. Physical effects of oil in water:
Reduction in dissolved oxygen – oil films are
able to retard significantly the rate of oxygen
uptake by water.
Reduction in light penetration – oil slick
decreases the light intensity up to 90%
Smothering – Smothering coats of oil have
killed lichens and algae along the shore line.
13. Garbage waste need oxygen for
decomposing
It is very harmful to our environment because
of the way it is currently being disposed
It possess dangerous risk to our land, water
and air
Landfill disposal if leaked, will contaminate
surface and ground water which in turn will
travel to the nearest ocean or lake and poison
the wildlife there.
Incinerating trash has bad effect on the
environment as it contributes to air pollution
which causes global warming.
14. Conclusion:
Disposing of waste has
huge environmental impacts and can
cause serious problems. ... Some waste will
eventually rot, but not all, and in the
process it may smell or generate methane
gas, which is explosive and contributes to
the greenhouse effect. Leachate produced
as waste decomposes may cause pollution.
