Haze raises PM2.5 levels in Singapore; PSI unhealthy in two regions

· Climate · Singapore

Singapore's National Environment Agency said PM2.5 levels were elevated in three regions of the country, with the Pollutant Standards Index reaching unhealthy levels in two of them. The agency said the haze over Singapore could ease on Tuesday, since showers are forecast for the country and the surrounding region. The advisory concerns fine particulate pollution, the tiny particles that pose the greatest health risk in haze episodes and that can penetrate deep into the lungs. No further details on the affected regions or readings were given. The immediate effect is a health caution for residents, with relief expected to depend on the forecast rain.

Why it matters：Transboundary haze is a recurring public-health and diplomatic issue in Southeast Asia, and shifting pollution levels affect daily life and outdoor activity across the region.

Key points

  • PM2.5 elevated in three regions, with unhealthy PSI in two
  • The National Environment Agency expects showers to reduce haze on Tuesday
  • Fine particulate matter is the main health concern during haze episodes
