Singapore residents concerned as haze turns rainwater grey

Singapore residents are reporting discoloured, greyish rainwater as the country faces a severe haze crisis. Authorities have closed some outdoor facilities and are distributing N95 masks as air quality reaches unhealthy levels.
Why it matters
The incident highlights the severe environmental and public health impacts of regional air pollution on urban populations.
KUALA LUMPUR, Oct 16 — Heavy rain in Singapore yesterday morning failed to ease concerns over the haze, with some residents reporting blackish-grey rainwater collected in buckets outside their homes.
AsiaOne reported that a resident from Ang Mo Kio, identified only by her surname Zhong, had collected three buckets of rainwater that appeared blackish-grey.
A video shared on the Singapore Parents Instagram page also showed several buckets of murky rainwater, prompting concern among netizens.
According to a CNA video, raindrops can draw pollution particles out of the air as they fall. However, as haze contains fine smoke and pollution particles, rainfall may not remove them all quickly, resulting in discoloured rainwater.
