French Wine Test Finds Pesticides in Each of 92 Bottles Analyzed

"Laboratory testing of 92 French wines from across the country found pesticide traces in every bottle, ... Wine producers in France account for 3.7 percent of farmland and 20 percent of the country’s pesticide use, the group said..."

... even bottles of 'organically grown' wine had traces of pesticides.

"The wines were tested using gas and liquid mass spectrometry that allowed detection of “very low” quantities of molecules of [between] 1 to 10 micrograms, ..."

The quantities are very low.  The larger impact is probably felt by field workers and any organisms, including people, downwind or downstream.
