Scientist: Giant, city-wide sprinkler systems could cut air pollution

ZHEJIANG, China, Jan. 6 (UPI)

Spraying water into the air from sprinklers on tall buildings and towers,
like watering a garden, could cut air pollution in Chinese cities, a
scientist says.Shaocai Yu of Zhejiang University in China and North
Carolina State University, writing in the Springer journal Environmental
Chemistry Letters, suggests spraying water into the atmosphere to simulate
natural types of precipitation that are able to collect and remove aerosol
and gaseous pollutants from the air.The approach could help reduce the
severe air pollution and heavy haze experienced in many Chinese cities
during a decades-long burst of economic and industrial growth, Yu said.The
water-based geoengineering scheme could help to reduce the fine particle
concentration in the atmosphere efficiently, he said.Because the water
could be collected and reused, adopting this kind of plan would not
exacerbate existing water shortages, he said."With careful and considered
evaluation beforehand for each area in the cities, this geoengineering
approach can be environmentally safe without significant side effects," Yu
wrote. "It can also be deployed easily within communities and on a massive
scale at low cost.""If you can spend half an hour watering your garden, you
can also spend 30 minutes watering your ambient atmosphere to keep the air
clean with this technique."
