Q & A

How many people die each year in Kenya due to air pollution according to the World Health Organization?

Approximately 19,000 people die each year in Kenya due to air pollution, as reported by the World Health Organization.

Which city is mentioned as one of the polluted cities in the script?

Nairobi is mentioned as one of the polluted cities, killing its citizens due to air pollution.

What is the biggest contributor to air pollution in Nairobi according to the script?

Vehicle emissions are the biggest contributor to air pollution in Nairobi.

What is the impact of air pollution on the respiratory system as explained by Dr. Naid Marali?

Air pollution impacts the respiratory system by causing harmful reactions in the airway, leading to excess inflammation, which is similar to the pathway of how cancer cells are formed, increasing the risk of airway diseases such as asthma, chronic obstructive pulmonary diseases, chest infections, and lung cancer.

What is the role of traffic police officers in relation to air pollution as described in the script?

Traffic police officers are responsible for controlling the traffic that contributes to air pollution, and in doing so, they expose themselves to the dangers of air pollution, which can affect their health.

How long do traffic officers typically spend on the road in Nairobi?

Traffic officers in Nairobi typically spend eight hours on the road, sometimes even more, which leads to more exposure to air pollution.

What measures are taken by traffic officers to protect themselves from the effects of pollution while on duty?

Traffic officers are advised to wear masks to prevent toxic contaminants from entering their respiratory system.

What are the chemical components released during combustion in vehicle emissions that are considered toxic?

The chemical components released during combustion in vehicle emissions include particulate matter (PM), carbon monoxide (CO), nitrogen oxides (NOx), and sulfur dioxide (SO2), which are considered toxic to humans and the environment.

What is the estimated percentage of Nairobi's PM2.5 air pollution concentrations attributable to road transport?

An estimated 40% of Nairobi's PM2.5 air pollution concentrations are attributable to road transport.

What is PM2.5 and why is it a concern for health?

PM2.5 refers to particulate matter that is 2.5 microns or less in diameter. These tiny particles are inhalable into the lungs and can induce adverse health conditions, including respiratory and cardiovascular diseases.

What measures are being taken by the government to mitigate the effects of vehicle emissions?

The government is implementing measures such as vehicle emission testing, requiring private vehicles to be tested every two years and commercial vehicles annually. They will also be administering emission compliance stickers for vehicles that pass the tests and designating testing centers for this purpose.

What is the current state of air quality in Nairobi as per the script?

The current state of air quality in Nairobi is rated as moderate, which is generally considered unhealthy, posing a risk to vulnerable groups such as asthmatics and people with chronic lung diseases.
