Phase 1 (2005 Deadline)

Determination of Heavy Metals and Polycyclic Aromatic Hydrocarbons in
Airborne Particulates in Lahore, Pakistan, and Madison, Wisconsin, USA

Pakistani Funding (HEC): $107,625
US Funding:   $  80,000
Project Dates on US Side: January 1, 2006 - December 31, 2008 (Completed)

Project Overview

Implementation of an air pollution control strategy is still at its early stage in Pakistan, and while some emissions standards have been set, national and provincial environmental protection agencies lack sufficient resources and expertise for monitoring and enforcement. The researchers involved in this project collected data on ambient air quality in Lahore, especially with regard to particulates, heavy metals, and polycyclic aromatic hydrocarbons. Source apportionment techniques developed at the University of Wisconsin were then applied to the Lahore data to identify the main sources of air pollutants. By identifying and quantifying the pollution sources, they worked to devise a cost-effective control strategy to improve air quality in Pakistan. The project included improvements in the laboratory infrastructure at UET Lahore as well as in the capabilities of its faculty to conduct research and train much-needed new PhDs in this field.

Major Results

  • Demonstrated very high concentrations of PM 10 and PM 2.5 pollution in Lahore, with the toxic components and biological activity of the particular matter in Lahore being much more toxic on a per unit mass than PM in many other highly polluted urban areas around the world
  • Facilitated three annual summer-long research visits to UW-Madison by the Pakistani principal investigator 
  • Provided research experience to five U.S. and six Pakistani students
  • Produced seven papers and three international conference presentations
