Over 21 million pounds of glyphosate are applied to non-agricultural sites annually.
The major transport routes off the treated area for glyphosate include runoff and spray drift. Glyphosate is expected to reach surface water primarily through spray drift; however, transport in runoff may also occur primarily via sorption of glyphosate-metal complexes to eroded soil. The highest concentrations of glyphosate in surface water are in urban environments and in the vicinity of local use areas.
Technical glyphosate is practically non-toxic to terrestrial and aquatic animals on an acute exposure basis. Toxicity studies, particularly acute aquatic toxicity studies, show that while some formulated products are less toxic than glyphosate active ingredients alone, others can be up to 2 orders of magnitude more toxic. Formulated glyphosate is moderately to highly toxic to fish, highly to very highly toxic to aquatic invertebrates, moderately toxic to mammals, and slightly toxic to birds on an acute exposure basis.
And yet glyphosate herbicides are sprayed directly into the water and the sprayers believe it is safe!
In both terrestrial and aquatic animals, technical and formulated glyphosate demonstrate a variety of growth and reproductive effects at a range of chronic exposure concentrations.
There have been over 1,000 reported ecological incidents involving glyphosate use for birds, fish, terrestrial invertebrates, and terrestrial plants.
NLAA determinations were made for 119 species and 33 species’ critical habitat and LAA determinations were made for 1676 species and 759 critical habitats. Of the LAA determinations, the majority - 93% of species and 97% of critical habitats - were considered to have moderate evidence. The majority of the moderate evidence designations were based on non-agricultural uses being the main risk drivers and the lack of availability and uncertainty in usage data associated with these use sites.
Non-agricultural UDLs, including Non-cultivated, Open Space Developed, Right of Way, Forest Trees and Developed were the use sites most frequently associated with predicted impacts to species or critical habitats with LAA determinations, although numerous other non-agricultural and agricultural UDLS may also impact species.
The Aquatic Herbicide UDL, which has overlap with all aquatic species ranges and critical habitats, is also anticipated to have potential impacts on aquatic species for which a LAA determination was made.
