Environmental Health: Air pollution

• Urban and industrial areas in Zimbabwe produce waste gases which enter the atmosphere
• Often these gases are toxic and contain a high level of smoke particles
• A thick haze of smoke often forms over most big cities
• This is known as smog
• Gas and levels of pollution should monitored as they lead to several problems
• Among them are pollution related diseases
• These include bronchitis 
• This is the irritation or inflammation of the bronchi inside the lungs
• Pollution should be regulated around residential and populated areas
• Asbestos and cement dust produced during their manufacture can lead to health problems if breathed in
• Asbestos can lead to Asbestosis a lung disease
• They also lead to increased risk of contracting cancer
• In large cities (mega cities) such as Beijing pollution is a major problem people wear filter masks to protect themselves
