How much severe Delhi's Pollution actually is ?

-
If you are living in Delhi, you can experience sudden increase in pollution level. All of the Delhi is covered in dense smog, resulting in breathing problems and itching in eyes, as immediate consequences, and many other harmful health condition.

So how to quantify this pollution, everywhere in the news it is being said that pollution is severe, but how much severe is it actually ? Let's look at it.
Quality of air is measured by measuring various component of pollution in the air which can be Particulate matter(PM), Ozone, Nitrogen oxide, sulfur dioxide and carbon monoxide. The concentration of these pollutants is measured in micro grams per cubic meter (μg/m3). Right now particulate matter is causing havoc over Delhi.

Particulate Matter(PM): These are small solid or liquid particle with, diameter less than 10 micro meter called PM10 and diameter less than 2.5 micrometer called PM2.5. PM2.5 is more harmful as it can go into the lungs and affect our health, it could cause lung cancer also. Stubble burning in the neighboring state of Haryana, Punjab and UP is the main reason for increase in concentration of PM10 and PM2.5 in Delhi.

Following charts indicates different level of AQI value:


This chart shows how serious the problem is, Delhi is looming on severe level from 2-3 days. PM10 and PM2.5 concentration has increased to a drastic high, which has made Delhi air nearly unbreathable. High concentration of PM10 and PM2.5 has many serious adverse effect on both, health and environment. According to EPCA site, exposure to PM particles can affect both your lungs and heart, it give rise various health complication, including:

  • Premature death in people with heart or lung diseases
  • Nonfatal heart attacks
  • Irregular heartbeat
  • Aggravated asthma
  • Decreased lung function
  • Increased respiratory symptoms, such as irritation of the airways, coughing or difficult breathing.
Adverse environmental effects include, Visibility impairment. Moreover these particles can be carried by wind and then settle on ground or water which could have negative impact like:
  • Making lakes and stream acidic
  • Changing the nutrient balance in coastal waters and large river basins
  • Depleting the nutrients in soil
  • Damaging sensitive forests and farm corps
  • Effecting the diversity of ecosystem
  • Contributing to acid rain effects
The maximum limit for AQI is 500, and Delhi has crossed that limit. So, the pollution in Delhi is real at hazardous level, it is quite similar to the Great smog of 1952 in London, which took the life of nearly 4000 people. However, during Great smog of London SO2 level was also high, which in Delhi is at moderate level.

The condition is quite worse here too, this dense smog could result in premature deaths. Government should immediately take some concrete steps for the well being of dwellers of this city.

Harmful impacts of slums on society and people living in it

-
The rapid urbanization in conjugation with  industrialization has resulted in the growth of slums. As we have discussed in previous post that how the shortage of land for housing, the high prices of land beyond the reach of urban poor and a large influx of rural migrants to the cities fuelling the development of slums. These slums give rise to many problems in the urban areas. The major problems of slums in India are as follows:- Shortage of space: About 77.6% of the urban dwellers in Mumbai reside in one room and lakhs of them sleeps on the footpath. About 62% of the households of the metropolis reside in these slums. This give rise to the problem of shortage of space.
Prone to natural and man-made hazards: As in slums, houses are crammed in a little space, they are often prone to dangerous hazards like floods, water logging, fire etc. Extent of hazard is increased because of high population density. The slum areas of Delhi specially Yamuna-Pushta are affected by flood-water of Yamuna…

6 Factors responsible for the growth of slums in India

-
A slum, commonly called Jhuggi-Jhopris in India, is residential area where the dwellings by reason of over-crowding, lack of ventilation, light and sanitary facilities, unhygienic conditions and other set of factors are detrimental to safety, health and morals. According to the estimates of Town and Country Planning Organization, about 21.2% of urban population lives in slums. This proportion is even higher in metropolitan cities like Kolkata, Mumbai, etc. First question which arises here is that how slums developed, what are the requirements for their development. There are varieties of factors which helps in the formation of slums.
 Growth rate of population (Urbanization) First of all the growth rate of Indian population is very high and this growth rate is much higher in the urban areas because of the migration of large number of people from rural to urban. Due to the poverty, unemployment, lack of other amenities and more importantly to elevate their status, people migrate to ur…

In the previous post we discussed the physical features of Shiwalik Himalayas and found out that how Shiwaliks created the beautiful Dun valleys. This post will discuss about the geography of other two ranges of The Himalayas- The Middle or Lesser Himalaya and The Great Himalaya which are the other two division of The Himalayan Ranges.
