Basically, the industrialization of society, the introduction of motorized vehicles, and the explosion of the population are factors contributing toward the growing air pollution problem.

Some main components of air pollution

The primary air pollutants found in most urban areas are carbon monoxide, nitrogen oxides, sulfur oxides, hydrocarbons, lead, and particulate matter (both solid and liquid). These pollutants are dispersed throughout the world's atmosphere in concentrations high enough to gradually cause serious health problems.

Sulphur dioxide is the major pollutant due to human activities. Burning fossil fuel containing

Sulphur dioxide is also the main component of smog, one of the most common forms of air pollution. Smog is basically a mixture of fog and smoke. It occurs when a layer of warm air lies on top of cool air. The cool air, together with the pollutants such as sulphur dioxide, is thus prevented from escaping.

New technological developments do much to control air pollution. For example, several types of devices have been developed to prevent harmful gases and particulate from leaving industrial smokestacks. These devices include filters that trap the gases and particulate that would otherwise be released into the air with waste gases.

Sulphur dioxide reacts with oxygen and rainwater in the air to from sulphuric acid. Sulphuric acid is a component of acid rain, which leads to water pollution, in turn causing the death of aquatic organisms in several lakes and rivers, and damaging property.
