It is an unchanging proven fact that air air pollution in Hong Kong not only ends in a waste of huge amounts of cash, but also leads to deterioration on the general well being standard of the Hong Kong inhabitants.

No doubt that it is the task of the Government of Hong Kong to work out measures to tackle air pollution. Nevertheless, it is also the obligation of the basic public to help and cooperate with the Government. In this essay, I will focus on two important causes of air air pollution, which are vehicle emission and indoor air air pollution. As for the part of problems, I will focus more on their results to the nicely being of most people.

For the part of options, I will focus extra on the problems of the Government and what the common public can do to assist to eliminate the problems of air air pollution, in order that Hong Kong can proceed to prosper in the coming future

The causes and issues:

1.Vehicle Emission

Vehicle emission certainly plays a dominant role in contributing to the intense air air pollution in Hong Kong. Newer engines cause much less air pollution but many of the vehicles in Hong Kong are poorly maintained. This is both because people can’t afford the excessive upkeep value or they don’t have the sense to take action.

Both causes contribute to the intense air pollution in Hong Kong. The Clear The Air Organization in Hong Kong observes that Hong Kong has roughly 146,000 diesel automobiles. The legally imported diesel in Hong Kong has a maximum sulphur content material of 0.05%.

These diesel fuels used account for 70% of the whole distance traveled on the roads. It also states that in Hong Kong, 98% of RSP and 85% of NO2 from vehicular sources come from diesels. Besides, industrial trucks in Hong Kong, like truck, and lorries are on the roads all the time. They contribute to 55% of the general RSP and 43% of the NO2 in Hong Kong. Thus this large proportion of air pollution particles from the emission of autos causes Hong Kong to be one of many busiest cities, in addition to one of the most polluted cities in the world.

2.Indoor Air Pollution

It is simple for people to note the outdoor air pollution in Hong Kong, but how about indoor air pollution? It is estimated that folks spend 90% of their time indoors. In Hong Kong, most of the indoor locations are air-conditioned, which means, there is a high chance that the air is poorly ventilated, especially when a large group of persons are crowded together in small places. Examples of the indoor pollutants are, VOCs from paints, paint thinners, and glues for development of furniture and buildings; environmental tobacco smoke from smoking; carbon dioxide from human respiratory; radon from decayed parts of some forms of cement blends; formaldehyde that comes from new furnishings and renovation supplies; RSP from sanding wooden, operating tools and printing; harmful micro organism from ventilation, air con techniques, and the ozone.

These trigger many different health issues, corresponding to irritation and respiratory issues, coughs, acceleration of the reoccurrence of asthma, pores and skin rashes, complications, legionnaire’s illness and eye irritations. Prolonged exposure to those indoor air pollution sources could even trigger mind harm, leukemia and most cancers. Although each individual in the community is pronged to those different results of indoor air air pollution, some individuals locally are extra vulnerable to these uncovered threats of life.

They are the individuals with respiratory illnesses similar to asthma and chronic bronchitis, youngsters and the elderly. Children are more at dangers than adults because children’s lungs are nonetheless creating and that their airways can be more simply obstructed when irritated. They are also nearer to the ground than adults and so nearer to the emissions of the vehicles and the heavier pollutants. As for the aged, their lungs and their ability to resist irritants and diseases are deteriorating and thus more susceptible when exposed to the different pollutants talked about above.


1 What does the Government plan to do?

The government in these current years has sought out a variety of methods and insurance policies to sort out air air pollution caused by vehicle emission. Firstly, in accordance with a news launch from the Government News & Information System, 2000, it’s stated that the Government has new action plans to encourage the introduction of environmentally-friendly hybrid vehicles or these powered by natural gasoline or gas cells. In addition, these initiatives might be carried out in the subsequent few years, hoping to reduce the emission of particulates within the urban space by 70% and nitrogen oxides by greater than 19%. Secondly, in the same news release, it is said that the conversion of LPG taxis is significantly supported by the Government with a grant of $40000 for the taxi drivers to buy LPG taxis. There is also a low pump value of LPG and will save about $35000 of the running cost a yr. Thirdly, in 1995, the Government arrange the Environmental Protection Department to measure the air pollution in Hong Kong.

The air pollution is measured by the Air Pollution Index (API), and is used to report the air high quality in numerous districts in order to warn people with respiratory problems to prevent places which would possibly be highly polluted. (Aidia et al, 2000). Fourthly, there are about 40000 medium and heavy diesel automobiles in Hong Kong and are all subjected to ongoing operational trials and that the Government intends to provide free installation of catalytic converters which may scale back up to 50% of the particulates emitted for all old diesel engines.

Fifthly, the Government intends to scale back the benzene content in petrol to less than 1% in 2000, reduce the sulphur content material of motor diesel to less than zero.035% in January of 2001 and to introduce extremely low sulphur diesel, with lower than zero.005% of sulphur, initially in the franchised bus fleet. (Yeoh, March 2000). Lastly, based on The Planning, Environment, and Lands Bureau in 1999, it is decided that there might be a smoky vehicle management program and introduction a complicated smoking check by a chassis dynamometer to examine the smoke emissions of smoky autos. From the same source, additionally it is mentioned that the police shall be geared up with portable smoke meters to spot smoky automobiles.

2 .What can people do?

As for indoor air pollution, there are different ways to cope with those dreadful particles. According to Borwein (2000), there are six ways to deal with the problem of indoor air pollution. It is at all times good to put in indoor air cleaners. This can help to filter the mud particles, the molds, and tobacco smoke in the air and maintain the standard of the air indoors, significantly in bedrooms. It is very additionally essential to have exhaust followers, gasoline stoves and clothes dryers vented correctly to the surface of the flat in order that the polluted air is not going to linger inside the house, causing the quality of indoor air to lower. In further, it’s also essential to clean and dry the filters and evaporation trays of dehumidifiers, fridges, air cleaners, and air conditioners to stop the dust from staying there and decrease the workability of these electrical home equipment.

It is advisable to scrub the flat incessantly and hold it freed from mud in order that allergies and respiratory problems could be prevented. Also, we should attempt to remember that we should by no means smoke indoors, especially when the place just isn’t ventilated well. This is to stop irritations to our respiratory systems and that extended exposure to tobacco smoke may cause cancer. A vital action to take to deal with indoor air air pollution is to attempt to ventilate the indoor locations that we go. It can be essential to remember that if essential, keep away from the construction sites, decorating flats, and rooms.

3.Other issues that might be accomplished:

Thus, in my view, to halt air pollution in Hong Kong, there are some things that the Government can do. First, college students in every stage of schooling should be taught the sense of citizenship. Second, the Government can manage extra large-scale public features and actions to educate folks in a large extent. Third, employers of drivers of vehicles and lorries may help to set laws for stopping drivers from using diesel from the mainland which is of a lower quality and leads to the emission of far more polluted within the area of Hong Kong. Fourth, each particular person in Hong Kong ought to be responsible for defending the breathing environment. If anyone sees a smoky automobile or idling engines within the surrounding district, they ought to report it to the Environmental Protection Department so that the authorities can act as quickly as possible. Finally, the Government can attempt to contemplate the implementation of BioDiesel in Hong Kong. This type of BioDiesel is made from transformed used cooking oil and greasy faucet waste. It contains no sulphur and emits much lower levels of poisons and harmful particulates and is much less harmful to the human physique than strange diesels.


It is an unchanging proven truth that the living normal of the world is bettering and the air quality is declining, especially in Hong Kong and the encircling territories. If we as citizens of Hong Kong do not attempt confront the threats of air pollution critically and don’t attempt to cooperate with the problems of the Government, our dwelling commonplace, our health standard and finally our financial standard will surely deteriorate to nothing in no time.
