Instead, it is formed by the interaction of ultraviolet (UV) light from the sun on nitrogen oxides.

As the toxins and carcinogens are unlikely to leave our body, they continue to accumulate causing long-term health effects. We need to formulate a plan to improve neighbourhood air quality and scale-up solutions for everyone in the community.” We couldn’t agree more. Lead image courtesy of Healthy Matters HK. This was corroborated by Dr Marco Ho, former deputy chief executive at Queen Mary Hospital and an allergen specialist in paediatric immunology and infectious diseases, who said that pollution “does affect the quality of life of eczema patients, who have to go for more hospital visits and suffer itchy skin” as well as vulnerable groups, such as those with preexisting heart and lung complications, smokers, children and the elderly. When asked about what Hong Kong authorities are doing to control ozone, David Ho shared that more stringent measures have to be introduced across all emission sources, which will require more regional government partnerships, as ozone can be carried over by strong winds. Due to its super small size, PM2.5 is like a tiny vehicle and is able bring other toxic substances such as heavy metals (damaging nervous system) or carcinogens all from combustion sources down to our blood streams (might lead to blood vessel damage and blockage), to our heart (heart attack), our brain (Stroke) and other parts of our body with the potential to cause cancers.

Health alert: everyone may experience more serious health effects, Everyone should avoid all outdoor exertion. Good news aside, Hong Kong is still battling ground-level ozone pollution, which has risen over the years. These groups, he explained, are at risk of health issues, especially from PM2.5 micro-particles that can deposit in the inner airways, which has led to more hospital visits during poor air quality episodes. Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects, Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion. To monitor the quality of the air over Hong Kong, the Environmental Protection Department (EPD) operates fixed measuring stations for gaseous and particulate pollutants. Professional Air Quality Monitoring Stations.
Pollution levels generally vary from medium to high, although the biggest problems are at roadside levels in built-up areas like Causeway Bay , Central , and Mongkok . Turns out, while the basic measurement system used around the world is fairly standard (all sensors are basically the same), there is no universal air quality information system, according to David Ho.
One of the studies cited in the talk was the 2006 Civic Exchange Report conducted by HKUST and CUHK, which found that air pollution was responsible for 6.8 million family doctor visits related to respiratory problems, 64,000 hospital bed-days and 1,600 premature deaths each year in Hong Kong. On the street level, diesel vehicles – especially buses and trucks – are the main culprits for pollution.

Ozone can irritate eyes, and when we inhale ozone from nose, throat down to the trachea and lungs, the gas will attack the mucous membrane lining along the whole track leading to a different levels of discomfort due to symptoms like coughing, wheezing, inflammation of lungs and difficulties in breathing.
As David Ho explained, tackling PM2.5 levels is more straightforward, controlling vehicle emissions is key here, and Hong Kong has made good progress on this front.
