Pollution introduction pdf

Ozone causes dryness of the mucous membranes, changes vision, causing headaches, congestion of the lungs, and oedema. SO2 causes dry mouth, scratching the throat, bright eyes and disturbed respiratory tract.

Cotton dust leads to respiratory problems, e. So noise pollution is an unwanted noise thrown into the atmosphere without looking at the possible negative consequences. In our country, urban growth and industrial development have become two problems. Cities and towns sprang up with an industrial focus. The lack of urban planning has led to the collapse of residential, commercial and industrial spaces. Houses, schools and hospitals are close to industry. All the benefits of industrial development and civilization such as engines, horns, heavy and light machinery, work and movement, noisy radios, very high aircraft have been disrupted and irritating.

Our ears can hear the typical conversation between decibels. Modern chat has an audio value of 60 decibels. An amount of more than 80 decibels causes noise pollution. Noise exceeds decibels. Persistent noise affects a man physically and mentally. Physical effects include narrowing the arteries, pale skin, stiff muscles, and high blood pressure leading to depression and shock.

The loud noise emitted by industrial plants, bottle presses, and high-altitude aircraft over a long period disturbs and permanently impairs hearing. Offices, factories and crowded places where noise is common can cause irritation, headaches, fatigue and nausea. Water is essential to life, and all know this fundamental truth.

It needs to meet our basic needs in daily life, namely, cooking, drinking, bathing, sanitation, irrigation, power generation, cooling and manufacturing of various industrial products and industrial waste disposal. During all these processes, undesirable substances are added to the water sources on a large scale. It changes the introductory chemistry of water in rivers and streams.

That is why we need to purify water and save water for the benefit of future generations. Water pollution can directly affect the kidneys and liver due to the content of Cadmium. The ingredients of mercury, arsenic and lead are toxic and harmful to chemicals as they affect even water purifiers, e. Today, a majority of UN Member States recognizes environmental rights. As of , over countries guaranteed their citizens a right to a healthy environment, with the majority of countries building this into their national constitutions.

Although no international agreement explicitly recognizes the right to a healthy environment, national constitutions have played a vital role at the forefront of human rights and environmental protection. The majority of constitutional environmental rights include substantive, procedural, and emerging rights, such as the right to health and food, while others refer to policy-based, reciprocal-duty, and miscellaneous provisions.

Encouragingly, more governments, industries and citizens are moving towards sustainable materials management, greater resource efficiency, less environmentally damaging chemistry, clean technologies, and circular economies, as part of a more comprehensive transformation towards a sustainable economy.

Trade can lead to greater environmental burdens in countries that extract and produce resources, as such activities generate waste and emissions. But trade can also provide solutions in terms of improved environmental goods and services. However, the capacity to adequately tackle pollution varies hugely across regions, social groups and genders.

At the same time, responses by governments, business and citizens to pollution remain sometimes limited in scope and scale and to date, there are no legally binding agreements that systematically address pollution in all its forms.

If global and regional environmental agreements provide a partial framework, there are many gaps. For example, some agreements are only target-based, some are time-bound, while others cover also compliance-related actions, monitoring and reporting. For example, voluntary initiatives and global alliances — on topics such as fuel efficiency improvements, cleaner air and lead in paint — have addressed some of the more urgent issues, yet much more remains to be done to control and prevent pollution.

It is obvious from many case studies that tackling pollution has already brought multiple benefits even if current responses may still be limited and inadequate. Projections indicate that further actions have the potential to enhance both health, well-being, and the economy. Two success stories show what can be achieved: the healing of the ozone layer and the phasing out of lead in fuel. However, these technologies also require materials and energy upfront to produce the equipment, and as a consequence, may increase environmental impacts.

Solutions to help remove pollutants and detoxify our environment exist around the world. These need to be expanded, shared, and scaled up in order to avoid risking further exposure of humans and ecosystems to current and future pollution as well as increasing the costs of clean up.

Improved risk assessment of new pollution sources is also urgently needed. Resource efficiency over the whole production -consumption system in particular can generate products which are identical or have the same functionality as when using traditional technologies and processes, while also reducing critical emissions and mitigating resource requirements and environmental impacts in the upstream processes.

Moving to less-polluting and nature-based technologies also offers economic and employment opportunities. Renewable energy provided jobs for 9. Waste recycling and reuse also offers the chance to convert waste into economic opportunities, including jobs. As secondary materials replace virgin materials for example phosphate from fertilizer nutrient recovery , they reduce the resource and environmental footprint of growth, but they can also have income and job impacts on primary exporting countries.

Thus, careful and inclusive transition planning is required for those affected by these transformations. Implementation gaps are in particular due to a lack of resources; inadequate administrative, financial, institutional and technical capacity, and the absence of inter-ministerial coordination and political will. Absence of inter-ministerial coordination being a key reason why action does not happen.

There is also insufficient recognition by different actors that producer and consumer choices have pollution consequences. Such choices — even in the presence of pollution policies and regulations — can be made out of habit, a feeling that one person or firm cannot make a difference. As already underlined, existing international environmental agreements and the Agenda for Sustainable Development present significant opportunities to accelerate actions to tackle pollution and improve the well-being of humans and ecosystems.

These links are detailed in the appendices of the report. A pollution-free planet is by far and away the best insurance for the survival and well-being of current and future generations of humans and ecosystems. To advance this goal, this report has the following five overarching messages. To reach these objectives, this report suggests a dual track of actions as framework for actions on pollution that UN Member States and other stakeholders may wish to consider to curb pollution around the world.

Ozone depletion, skin cancer, hearing loss, loss of eyesight, pulmonary problems, etc. Study About Environmental Pollution. The initiation of pollutants into the environment, either in the form of chemical substances or energy such as noise, heat or light , that can cause harm or discomfort to humans or other living organisms or that damage the environment is called pollution.

Air may get polluted by natural causes such as volcanoes, which release ash, dust, sulphur and other gases, or by forest fires. Burning fossil fuels, mining operations, exhaust gases from industries and factories are the few sources of air pollution that are caused by humans.

The impact of air pollution varied based on the pollutants released in the air. Learn Exam Concepts on Embibe. Noise Pollution: Noise pollution refers to an unwanted or excessive sound that affects human health, wildlife and the environment. Noise pollution is caused in two ways. Natural sources such as volcanic eruption, thunder, etc. Water Pollution: The contamination of lakes, rivers, seas, ocean, etc. The pollutants are generally introduced by human activities like improper sewage treatment and oil spills.

Water pollution is mainly caused by two sources, point sources such as municipal and industrial discharge pipes and non-point sources such as agricultural runoff, acid rain, etc. Petroleum, fossil fuels and oil spillage from the roads and during ship accidents, etc.

This has become an increasing and the most current pollution, owing to the increasing call of globalization everywhere.

Soil Pollution: Soil pollution depicts the contamination of soil due to the presence of toxic substances such as excessive use of fertilizers and pesticides, deforestation, industrial waste, oil spillage, disposal of plastic, etc. Due to soil pollution, the quality of the soil decreases, which makes land unfit for growing crops, construction of buildings, etc.
