Smog is a type of air pollution which is a mixture of smoke and fog. This describes the atmospheric condition of a particular area. This word was firstly used by H.A Des Voeux in 1905 to describe atmospheric conditions of towns and was popularized when he wrote a report on smog abatement league due to more than 1000 deaths were observed in Glasgow and Edinburgh during autumn of 1909 from this mixture of smog and fog. smog is of two types, sulfurous smog, and photochemical smog. Sulfurous smog is known as London smog which is caused by high concentration of sulfur dioxide coming from fossil fuels burning, coal, and due to the high concentration of suspended particles.
Photochemical smog is known as Los Angles smog that usually occurs in urban areas due to a large number of vehicles. This type of smog doesn’t need fog and smoke. Only nitrous oxides and hydrocarbons coming from vehicular emissions are needed.in Lahore photochemical smog is observed in summer while sulfurous smog is observed in winter. Air pollution is increasing due to industrialization and urbanization causing a destruction of our environment and affecting our climate. Climate has totally changed now. Smog is affecting our health while climate change is affecting our future in negative ways.
Lahore is one of the heavily populated cities of Pakistan having so many industries in its adjoining areas. A beautiful and charming city is now suffering a very dangerous type of air pollution known as smog just because of its citizen’s carelessness and selfishness. We are not safe either it is winter or summer. In winter a thick blanket of fog is mostly observed around us when we are unable to see one another at a small distance. When we come out of our home with the fear of getting ill and being injured in an accident. This fog reduces visibility to 0 level, not only visibility but it also puts the citizen into zero level work condition.it effects country’s economy very badly. It has many harmful effects on our health.
People have suffered from diseases such as asthma and lung diseases. Many people have died from smog in past years. According to Deutsche Welle Website, Lahore is now on the list of top 10 cities having worst smog in the world in 2014. Worst smog in Lahore is also observed in 2017.Smog in Lahore is not only observed in winter even also in summer it is observed. Reasons of this smog in Lahore are;
- Cutting of trees for construction purpose
- Establishment of industries such as coal power plants and nitrous oxides emissions from it
- Emissions from burning of Fossil fuels
- Vehicular emissions
- Burning of agriculture crops
The government of Pakistan has taken strict actions to control smog as more than 500 people complaint daily about the eye, throat irritation, accidents and deaths due to smog. Thirteen power plants were banned for working more than 12 hours, 100 people were arrested for burning crops. Lahore police have said that they have collected fines from drivers for not following emission standards in recent smoggy days was about 50,000$. Although many media campaigns have started by the government of Punjab and also by many private societies to provide awareness to people about smog. But still, there is need to make people understand about environment importance in their lives. This is all due to individual’s carelessness because we are playing a major role in our environmental destruction. But we need to understand that if there is no healthy environment then there will be no good future.
Smog has many health effects such as coughing, throat and chest irritation while leads to lung damage after exposure to smog for a long duration. breathing problem at the start may also lead to asthma attacks. eyes and nose irritation is mostly observed. According to World health organization, more than 60,000 people have died from air pollution.so we need to take certain precautions such as we must wear masks and glasses while working in smoggy areas or going outdoors. Try to avoid areas having more traffic preferring fewer crowd roads. The burning of agricultural material should be avoided. The high speed of vehicles should also be avoided. Fuel-efficient vehicles such as hybrid and solar energy consuming vehicles should be preferred.
We must use public transport and should prefer to walk rather than using our private vehicles. Because less fuel is consumed so prevention of smog creation will be done. this will not only reduce consumption of fuel and air pollution but also traffic issue would be under control Cutting of trees should be stopped. monitoring techniques for air emissions should be introduced in industries. But our first preference should be to work indoor while avoiding outdoor work. But the major reason for smog in Lahore is vehicular emissions and cutting of trees. The report that was presented to the government of Punjab has explained that the number of vehicles in Lahore has been increasing rapidly from the last few years. Trees act as regulators for the atmosphere as they make the air clean.in November 2017 Lahore was surrounded by dense smog We are responsible for making our environment unhealthy for us. We need to change our attitude towards it.
Although many of us have awareness about it we have to convey our knowledge to others. we need to protect not only ourselves but also our future generations. we are using vehicles for our comfort establishing factories to make lifestyle better and to earn more money without thinking about its harmful impacts without using monitoring techniques and cutting down trees for constructing our beautiful homes and other buildings without thinking about that what we are doing to our environment. We must think that if we have beautiful homes, more money and good lifestyle but the unhealthy environment and no health then it will be useless to have all that.
