Pollution problems and solutions essay

You'll notice that the air smells a lot cleaner during the summer and it's for good reason.
Kathmandu receives up to 80% of its total annual rainfall (1100 millimetres (43 inches)) during June, July and August. Such heavy rain washes the majority of the pollutants out of the atmosphere.

However, as soon as the rain stops, pollution levels slowly begin to rise, but because the rain is so frequent during these months, the air is simply washed clean during the next downpour of rain.



What's brick manufacturing got to do with air pollution in Kathmandu? Brick production is one of the traditional crafts of the Nepalese people and is a valuable source of employment. Many farmers just outside Kathmandu and elsewhere in Nepal like to supplement their income when it's too dry to produce rice crops.
They grow rice during the monsoon season (summer), and then lease their land to the brick manufacturers who then place portable brick kilns on their land during the winter. The average size of these kilns is 10 acres (4 hectares).
There's approximately 125 brick kilns in operation across the Kathmandu Valley and a number of them are located in the southern and south eastern parts of Kathmandu city. These kilns are only used during the dry season (December-May) since the wet weather in other seasons prevents the bricks from setting hard.
Brick kilns use coal as their main fuel source, and this contributes to the air pollution in Kathmandu by pumping considerable quantities of sulfur dioxide (SO 2 ) and other toxic substances into the atmosphere . Sulfur dioxide, emitted in large quantities can lead to acid rain.
These kilns produce highly concentrated amounts of fine respirable particulate matter, which interact with other industrial and vehicle fumes over Kathmandu. This combination of air pollutants is quite harmful to you if you happen to breathe in this air.
Numerous scientific studies have long shown that many people living near to brick kilns within Kathmandu suffer from asthma and other respiratory diseases more so than rest of the general Nepalese population . There's a growing body of evidence that shows that 95 deaths out of 10,000 deaths in Kathmandu Valley are due to the combination of poisonous fumes.
I should point out that these deaths are linked to people who have lived in the area all their lives and so if you are planning to stay a year or so, it's highly unlikely that this smog will cause long-term damage to your health.

Long-term exposure to particulate pollution can result in significant health problems including:

  • Increased respiratory symptoms, such as irritation of the airways, coughing or difficulty breathing
  • Decreased lung function
  • Aggravated asthma
  • Development of chronic respiratory disease in children
  • Development of chronic bronchitis or chronic obstructive lung disease
  • Irregular heartbeat
  • Nonfatal heart attacks
  • Premature death in people with heart or lung disease, including death from lung cancer

We also can help nature to purify the air. We all know that plant have a great protection function; they help us make this world a little bit cleaner, protecting from harmful substances. It means that we should plant and grow more greenery. In such a way we will make our world safer and cleaner. Besides, coniferous plants influence positively human health producing essential oils. It is a must to grow the plant to protect yourself from pollution. If you do not have possibility to plant a tree at your house, at least you can buy home plant and you will have your own clean world inside your home.

Adverse air quality can kill many organisms including humans. Ozone pollution can cause respiratory disease , cardiovascular disease , throat inflammation, chest pain, and congestion . Water pollution causes approximately 14,000 deaths per day, mostly due to contamination of drinking water by untreated sewage in developing countries . An estimated 500 million Indians have no access to a proper toilet, [43] [44] Over ten million people in India fell ill with waterborne illnesses in 2013, and 1,535 people died, most of them children. [45] Nearly 500 million Chinese lack access to safe drinking water. [46] A 2010 analysis estimated that million people died prematurely each year in China because of air pollution. [47] The WHO estimated in 2007 that air pollution causes half a million deaths per year in India. [48] Studies have estimated that the number of people killed annually in the United States could be over 50,000. [49]
