Millions in Hong Kong have been exposed to tear gas since June. From June to November, the police have fired more than 9,000 tear gas at different areas in Hong Kong.
According to the figures released in police briefings, around 88% of Hong Kong’s 7.4 million residents are affected by the impact of tear gas.
Numerous improper and potentially dangerous uses of tear gas have been captured on television on social media platforms.
Kwong Po-yin, a doctor and district councilor in Kowloon City, surveyed 170 journalists who had experienced heavy tear gassing while reporting from the front lines of protests in late July, more than 96.2% of them said having difficulty in breathing, 76% of them had skin rashes, and 40% of them had gastrointestinal symptoms such as diarrhoea or vomiting.
The dioxin level in different areas in Hong Kong has reached an extreme and dangerous level.
