IN NEWS<\/strong>: Why tiny pollutants called nanoparticles are more harmful than PM 2.5 and eating into your lungs, heart and brain.<\/p>\n\n\n\n

Nanoparticle pollution:
\u25cf Nanoparticles have dimensions typically ranging from 1 to 100 nanometers, making them vastly smaller.
\u25cf Nanoparticles have emerged as a silent but potent threat.
\u25cf These minuscule particles, measuring approximately 600 times smaller than the width of a human hair, possess the ability to infiltrate the body, reaching not only the lungs but even the brain.
\u25cf Due to their ultra-fine size, they can be suspended in the atmosphere for a long time and can travel longer distances, causing several health issues after exposure.<\/p>\n\n\n\n

The nano invasion of the lungs
\u25cf Their small size allows them to bypass many of the body\u2019s natural defence mechanisms, such as the filtering action of the nose and the mucus lining of the respiratory tract. Consequently, nanoparticles can penetrate deep into the lungs, posing serious health risks.
\u25cf One of the most significant concerns surrounding nanoparticles is their ability to reach the lower respiratory tract, including the alveoli \u2013 tiny air sacs where oxygen is exchanged with carbon dioxide.
\u25cf The small size of nanoparticles allows them to travel deep into the lungs, where they can trigger inflammation, oxidative stress and even cell damage.<\/p>\n\n\n\n

How nanoparticles affect the brain
\u25cf In addition to their lung-related threats, nanoparticles have shown the ability to breach the blood-brain barrier, a protective barrier separating the bloodstream from the brain.<\/p>\n\n\n\n

Preventive measures:
\u25cf Use Personal Protective Equipment (PPE) if you are exposed to nanoparticles at your workplace. This may include masks, gloves, and full-body suits designed to prevent inhalation or contact with nanoparticles.
\u25cf At home, utilising high-efficiency particulate air (HEPA) filters in air purifiers and maintaining good ventilation can help reduce indoor nanoparticle exposure.
\u25cf Avoid areas with high levels of air pollution, particularly during peak traffic hours, as much as possible to reduce inhalation risks.<\/p>\n
