Glyphosate & AMPA contents in different size fractions of wind-eroded sediment were studied. Glyphosate & AMPA were highly concentrated in soil particles <10 μm (PM10). Glyphosate & AMPA contents lowered with increasing particle size. Low soil moisture content inhibits glyphosate decay and increases its airborne transport risk. The risk of off-site airborne transport of glyphosate & AMPA with dust is very high.
