Aphid-stressed pines show different secondary organic aerosol formation

Plants emit gases, called volatile organic compounds (VOCs), that enter the atmosphere, where they can interact with other natural and human-made molecules to form secondary organic aerosols (SOAs). These tiny, suspended particles influence atmospheric processes, such as cloud formation and sunlight scattering. Now, researchers have shown that aphid-infested Scots pine trees produce a different mixture of VOCs than healthy plants, which then leads to different SOAs.
