The Singapore-MIT Alliance for Research and Technology duo have been taking readings along the shopping stretch for nearly two months.

SINGAPORE - Shoppers along Orchard Road on Saturday afternoon may have encountered an odd sight: two "ghost-busters" equipped with handheld and backpack scanners.

Actually research scientists, Mexican Erik Velasco and Swiss Gideon Aschwanden, from the Singapore-MIT Alliance for Research and Technology, have collected pollutant data along Orchard Road every weekday for nearly two months for an ongoing project.

They went out to log information on a Saturday for the first time yesterday as they felt the haze would offer too useful a data set to pass up.

"The haze has provided us with some very interesting information," said Dr Velasco, 39, with what looked like a futuristic iron in each hand.

One machine measures the number of dust particles in the air, while the other breaks them down by size: from PM10, the particles measured by PSI readings all the way down to tiny PM1 particles that are especially dangerous.
