Death rates rise through bad air cuts in Hong Kong

Visibility in Hong Kong now averages out at 12.6km (7.8miles), which is well below cities such as Paris, Berlin and Vancouver, where visibility stands at an average of between 20 to 25km.

While the amount of particulates in places like Vancouver and Auckland measured between 10 to 12 micrograms per cubic meter of air, Hong Kong had 80, or seven times more. The higher the pollutant concentrations, the lower the visibility. An increase in air pollutants increase the stickiness of elements in the blood making cells stick together and form clots resulting in heart attacks and strokes.

Researchers have found that for every 6.5km reduction in visibility, there is an average corresponding 1.113% increase in the number of non-accidental deaths, such as from heart and respiratory causes.

Anthony Hedley, Honorary Professor at the school of public health has said, “Loss of visibility is a direct measure of serious harm to health. Loss of visibility kills people”.

The director is the school of public health has stated that the government is still using outdated air quality objectives; therefore we should be more conscious of what we see and also reduce our pollution rates in order to overcome such problems.
