glyphosate

It’s not as safe as advertised, according to Conservation Biology.

Glyphosate has become the most commonly used herbicide worldwide, with a reputation of being environmentally benign, non-toxic and safe to wildlife and humans. However, studies have indicated its toxicity has been underestimated, and that its persistence in the environment is greater than once thought. Its actions as a neurotoxin and endocrine disruptor indicate its potential to act in similar ways to persistent organic pollutants (POPs) such as the organochlorine (OC) chemicals dichlorodiphenyltrichloroethane (DDT) and dioxin. Exposure to glyphosate and glyphosate-based herbicides for both wildlife and people is likely to be chronic and at sub-lethal levels, with multiple and ongoing exposure events in both urban and agricultural landscapes. Despite this, little research attention has been given to the impact of glyphosate on wildlife populations, and existing studies appear in the agricultural, toxicology and water chemistry literature that may have limited visibility among wildlife biologists. There is a strong case for the recognition of glyphosate as an ‘emerging organic contaminant’ and significant potential exists for collaborative research between ecologists, toxicologists and chemists to quantify the impact of glyphosate on wildlife and to evaluate the role of biosentinel species in a preemptive move to mitigate downstream impacts on people.
