Emissions from asphalt are a significant source of air pollutants in cities, especially in hot weather, a study shows. Researchers found that when asphalt was exposed to hot summer conditions it resulted in a 300% increase in emissions of secondary organic aerosols (SOA), an air pollutant known to have significant impacts on public health. Researchers...found commonly in roads, roofs and driveways, and heated it to between 40C and 200C in a tube furnace.
A love affair with woodburners, perfect topographical conditions and damp fuel make Masterton a magnet for smog. The central Wairarapa town often reaches hazardous air quality levels during winter, which could lead to spikes in respiratory-related hospital admissions. World-leading technology was rolled out last week to get a better picture of the town’s air quality fluctuations.
