Human health effects of air pollution
Human health effects of air pollution
Hazardous chemicals escape to the environment by a number of natural and/or anthropogenic activities and may cause adverse effects on human health and the environment. Increased combustion of fossil fuels in the last century is responsible for the progressive change in the atmospheric composition. Air pollutants, such as carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), ozone (O3), heavy metals, and respirable particulate matter (PM2.5 and PM10), differ in their chemical composition, reaction properties, emission, time of disintegration and ability to diffuse in long or short distances. Air pollution has both acute and chronic effects on human health, affecting a number of different systems and organs. It ranges from minor upper respiratory irritation to chronic respiratory and heart disease, lung cancer, acute respiratory infections in children and chronic bronchitis in adults, aggravating pre-existing heart and lung disease, or asthmatic attacks. In addition, short- and long-term exposures have also been linked with premature mortality and reduced life expectancy. These effects of air pollutants on human health and their mechanism of action are briefly discussed.

Global warming: Experts discuss measures to make capital climate-resilient
Global warming: Experts discuss measures to make capital climate-resilient
ISLAMABAD:
The move to make the federal capital a climate-resilient city has started with an initiative to assess its vulnerability to climate change and determine adaptation measures.
The Climate Change Division (CCD) and UN-Habitat convened a consultative meeting of stakeholders at the division’s office on Thursday to discuss the “Climate Change Vulnerability Adaptation Assessment in Islamabad Capital Territory.” At the meeting, Irfan Tariq, a director general at CCD, said after assessing risks and identifying gaps in institutional capacity, an action plan would be hammered out to address climate vulnerability. The plan would help improve the ability of city authorities t0 cope with changing weather patterns.
