pollutants are invisible, they can seriously impact our health, the environment, and our quality of life. Air pollutants may cause respiratory diseases, cancer and other health effects. Pollutants also may create odours and smog, diminishes the protective ozone layer, and contributes to other environmental problems, such as acid rain and global climate change. The air inside homes, schools, and other buildings also may contain pollutants that enter from outdoors and those generated indoors. Mold, radon, tobacco

Waste can be infectious, toxic and or radioactive, for improper waste management will create a tremendous threat to residents in these under developed cities worldwide, particularly those residents living close to dumpsites. Depending on a city’s level of waste management, waste may be disposed of in an uncontrolled manner, segregated for recycling purposes or simply burnt which can pollute water, food sources, land, air and vegetation. This method of waste disposal creates an environmental degradation

climate change are undeniable. Research conducted by the Intergovernmental Panel on Climate Change (IPCC) and other reputed meteorological institutions proves that average yearly temperature has been steadily growing over the last decades. The sea levels have also been rising, and the number of floods in different parts of the world has increased dramatically. Glaciers in the Northern Hemisphere have started to melt. This caused more icebergs to drift into the ocean. They currently pose a serious

photochemical because many of the chemicals found in urban air are formed by chemical reactions driven by sunlight. Among the many air pollutants in urban smog that are produced by photochemical reactions, one of the most abundant is ozone, O3 . Ground level ozone and other photochemical pollutants are formed in urban atmospheres by the reactions of oxides of nitrogen (mainly NO and NO 2 ) in the presence of hydrocarbons. In CHE 133 we learned about combustion reactions. A combustion reaction
