Q23 of 26 Page 1

Looking at the deteriorating air quality because of air pollution in many cities of the country, the citizens are very much worried and concerned about their health. The doctors have declared health emergency in the cities where the air quality is very severely poor.

(a) Mention any two major causes of air pollution.


(b) Write any two harmful effects of air pollution to plants and humans.


(c) As a captain of your school Eco-club, suggest any two programmes you would plan to organise in the school to bring awareness among the students on how to check air pollution in and around the school.

(a) There are a number of causes of air pollution.


•Smokes from thermal power plants, smelters and other manufacturing industries release particulate matter and air pollutants, which remain, suspend in the air. These industries also emit toxic harmful gases.


•The increasing use of automobiles is a major concern for causing air pollution. Automobile exhaust increases the concentration of CO2 and other greenhouse gases in the environment.


(b) Intense air pollution greatly affects health of all organisms.


•Air pollutants when inhaled by humans and animals get stuck in their respiratory tract and causes serious diseases such as asthma, heart diseases and eye irritation.


•Air pollution also affects the growth of plants. It leads to their premature death and reduces their yield.


(c) As a captain of my school eco-club, I will suggest following 2 programmes for awareness among students:


•An assessment of the school’s atmosphere should be carried out to determine the exact level of air pollutants. Next, a prevention plan should be developed that aims at lowering the concentration of air pollutants. Strict guidelines must be followed, which include restricting smoking around the school area and installing efficient ventilation systems in school.


•Periodic regular orientations should be held in school for creating awareness about air pollution and its harmful effects. Students must be encouraged to keep their environment clean and healthy.
