What is the correct sequence of path (from initial to final) of particulate matter exposure to humans?

A. Lungs

B. Soft tissues of organs

C. Blood

D. Inhalation

Choose the correct answer from the options given below:

The correct answer is - D, A, C, B

Key Points

• Inhalation
  • The exposure to particulate matter starts with inhalation of the particles present in the air.
• Lungs
  • After inhalation, the particles enter the lungs, where they can affect respiratory functions.
• Blood
  • Some particles can move from the lungs into the blood stream, enabling them to be transported throughout the body.
• Soft tissues of organs
  • Finally, these particles can deposit in the soft tissues of organs, potentially causing health issues.

Additional Information

• Health Impact
  • Exposure to particulate matter can cause respiratory diseases like asthma and chronic bronchitis.
  • Long-term exposure has been linked to cardiovascular diseases due to particles entering the bloodstream.
  • Particulate matter can also affect other organs, potentially leading to systemic health issues.
• Particulate Matter Sources
  • Common sources include vehicle emissions, industrial processes, and natural sources like wildfires and dust storms.
  • Efforts to reduce exposure involve controlling emissions and improving air quality standards.
