  1. 1.  To measure the elevated levels of different harmful gases existing in the atmosphere of some of the busiest and crowded markets of the city. Providing a clearer picture of the current scenario of pollution prevailing in the mainstream localities of Lahore. Explains the increase in the amount of pollution with the help of tables and graphs. Shows the wide variations of the amounts of gases currently present in the air from those of NEQS. Provides an overview of the general awareness found among people regarding the issue of pollution.
  2. 2. Pollution is the introduction of contaminants into an environment thatcauses instability, disorder, harm or discomfort to the ecosystem i.e.physical systems or living organisms.

  9. 9. After having a look on the observed values andthe standard values one can say that the pollutionlevels at all the sites (Anarkali, Urdu bazaar, KalmaChowk, Ichra) are too much greater than standardvalues. So we can assume that how poor is thequality control in Pakistan. There is no law to checkthe pollution when it is above standard concentration.There is need to take preventive measures because aswe know that our commercial areas are flooded withautomobiles and are releasing high amounts of gases(SO ,NO, Co) and dust particles which greatly increasethe respiratory diseases.
