👉 The "Singapore fumes" refer to a persistent air pollution issue in Singapore, characterized by high levels of particulate matter (PM2.5 and PM10) and other pollutants, particularly during certain times of the year. This phenomenon is primarily attributed to industrial emissions, vehicle exhaust, and construction activities, exacerbated by Singapore's dense urban environment and limited dispersion due to its geography. The fumes often linger in the air, especially in areas like Jurong East and parts of the Marina Bay area, affecting local residents and visitors. Efforts to mitigate this pollution include stricter emission controls, the promotion of public transportation, and green initiatives, but the challenge remains significant due to the city-state's rapid industrialization and population growth.
