Bees' foraging for flowers 'hampered by diesel exhaust'
http://www.bbc.co.uk/news/24364637
Honeybees' ability to find flowers could be hampered by a chemical in diesel exhaust, say scientists.
Tests showed that exhaust degraded some floral scent chemicals the bees "home in on" when they are foraging.
The study, published in Scientific Reports, also revealed that a specific group of chemicals found in diesel exhaust, known as NOx, diminished the insects' response to floral scents.
They say the results are evidence that air quality should be improved.
