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.
