How air pollution is making life tougher for bugs

Envirotec Magazine

Our research from 2022 revealed that when exposed to two common air pollutants at concentrations within EU air quality limits , the visits of pollinating insects to flowers plummeted by as much as 90%. Air pollutants like ozone are highly reactive and can degrade the signals by destroying the chemicals that make up a flower’s scent.
