Yifang Zhu in Courthouse News Service: Experts Say Dirty Air Will Return When Lockdowns End

Yifang Zhu, environmental health scientist at the University of California, Los Angeles, said in an interview the reduction in air pollution will unfortunately be short-lived once lockdown orders are lifted.

“If we go back to business as usual, emissions will go back and pollution will come back,” Zhu said. “The effect is very quick. Once traffic jams come back, emissions come back. [Current conditions don’t] have any lingering effect.”
