Study Notes

Executive Summary

Report titled "Breathing in Crisis" examines smog in Pakistan
Aims to identify causes, impacts, and solutions for this persistent issue
Emphasizes the severe socio-economic and environmental impacts
Includes both primary and secondary research analysis

Introduction

Smog in Pakistan is a persistent environmental problem, combining various pollutants
Pollutants include particulate matter (PM2.5, PM10), ground-level ozone, sulfur dioxide, and nitrogen oxides
Formed from sources like vehicular emissions, industrial activities, and crop residue burning
Impacts include poor air quality, respiratory problems, agricultural damage, and economic burdens
Smog's severity often increases during winter months due to temperature inversions

Effects of Smog

Health Impacts: Smog aggravates respiratory issues like asthma, bronchitis, and COPD; cardiovascular diseases (heart attacks, strokes) are also linked to long-term exposure. Children and elderly are more vulnerable to smog's effects
Environmental degradation: Air quality declines significantly, impacting vegetation, leading to crop damage
Economic consequences: Smog affects crop yields, impacting agriculture, a key economic sector in Pakistan. Medical costs increase due to smog-related illnesses. Loss of productivity among workers
Social and educational disruptions: School closures, affecting continuity. Reduces community well-being, leading to anxiety and stress related to health risks
Specific Impacts:
- Road accidents: Low visibility leads to accidents
- Air/rail disruptions: Delays and cancellations due to bad visibility, negatively impacting commerce and daily life.

Causes of Smog

Vehicular and Industrial Emissions: Rapid urbanization contributes to high emissions
Crop Residue Burning: Seasonal agricultural practices are a major contributor to pollutants
Other Factors

Mitigation Strategies

Policy Interventions: Stricter emission standards for vehicles, promotion of renewable energy sources, and sustainable agriculture practices
Technological Innovations: Implementing technologies for flue gas cleaning, air filtration systems, and incentives for electric vehicles
Public Awareness and Collaboration: Awareness campaigns, government collaborations will be critical for sustainable smog management

Methodology

Primary Data Collection: Survey using Google Forms, targeting individuals aged 18–25 living in urban areas of Pakistan
Secondary Data Research: Comprehensive review of credible academic research and publications about causes, effects, and solutions for smog in Pakistan

Data Analysis - Primary Data

Public awareness: High public awareness of smog's harmful effects and impacts on health and the environment
Government effectiveness: 40% of respondents felt government measures were moderately effective, while 35% felt they were inadequate
Individual actions: 65% of respondents perform regular vehicle maintenance to reduce emissions
Willingness for public transport: 85% of respondents are willing to use public transport to reduce air pollution

Data Analysis - Secondary Data

PM2.5 Levels: Average consistently above WHO safe limits
SO₂ Increase: Levels have risen, reflecting increased industrial emissions
NO₂ Decrease: Decrease is not sufficient to offset the issue
Humidity: Remained relatively stable, indicating potential for other pollutants to be drivers of air quality degradation.
Seasonal Variation: Particularly high in winter due to temperature inversions trapping pollutants

Solutions to the Crisis

National Electric Vehicle Policy: Promotes the adoption of eco-friendly vehicles
Agriculture Burning Control: Stricter penalties, promoting alternative crop residue techniques, and offering financial incentives
Brick Kiln Technology Improvement: Converting old kilns to Zig-Zag technology to significantly reduce emissions.
Vehicular Emissions Management: Implementing stricter standards, promoting electric vehicles, and expanding vehicle inspection centers
Industrial Pollution Control: Installing pollution controlling technologies in factories, enforcement, monitoring, and incentives for industries adopting cleaner production technologies.
Reforestation and Green Initiatives: Planting trees to act as air purifiers, community involvement, and protecting planted forests from deforestation

Dust Control, Fire Monitoring and Early Detection

Dust Control from Roads and Infrastructure: Initiatives for paving unpaved roads, using water sprays or chemical treatments, and introducing traffic regulations to reduce vehicular traffic.
Fire Monitoring and Early Detection: Using thermal anomaly technology to monitor and detect fires, and creating quick-response teams to address such incidents.
