On April 14, Hong Kong's Air Quality Health Index reached a 'very high' health risk category at 8 of the Environmental Protection Department's 18 monitoring stations. This spike in pollution levels is attributed to severe sandstorms affecting the region, with reports indicating that Hong Kong is experiencing its worst sandstorm in 15 years. The Hong Kong Observatory anticipates that these conditions will persist until mid-week. Meanwhile, air quality in Dubai has deteriorated, with the Air Quality Index (AQI) surpassing 200, making it the city with the dirtiest air globally. This decline is linked to a dust storm originating from the Iraq and Saudi Arabia border. The storm's intensity has been such that the Burj Khalifa, the tallest building in the world, became obscured. Additionally, Dhaka's air quality has also worsened, registering an AQI score of 133, categorizing it as 'unhealthy for sensitive groups.'
