Perhaps the only thing more pervasively toxic than crop chemicals, like glyphosate (Roundup) and atrazine, is these poisons combined with one another. A new study published in the journal Chemosphere has revealed that the amalgamated toxicity of certain pesticides and herbicides increases substantially in comparison to the toxicity of these same chemicals individually.
To make this discovery, researchers from France tested the cytogenetic effects of both glyphosate and atrazine, as well as their degradation products, aminomethyl phosphoric acid (AMPA) and desethyl-atrazine (DEA). Using an in vitro micronucleus assay, the team tested various mixtures of the chemicals on CHO-K1 cells, which were originally derived from hamsters.
Since most chemicals currently in use were only safety tested in isolation — if they were even safety tested at all — the team from the Aix-Marseille University (AMU) Laboratoire de Mutagenese et Toxicologie Environnementales decided to look at the combined effects of two of…
