In the wake of the recent glyphosate discussion, it became clear that there are some misconceptions on what „Maximum Residue Levels“ (MRLs) for pesticides actually are, and whether or not they have any toxicological basis (see comments to this post). So, here’s a brief overview. Europe In Europe, the setting of MRLs is regulated by…

The analysis was taken up and republished by „Our World in Data“ in a post titled „Is organic really better for the environment than conventional agriculture?“ However, both, the paper and the blog-post, miss a major point, perhaps the major…

I would like to take the opportunity to reply to a few comments made. I’m aware that it is a bit unfair to use the space provided by a blog to answer comments and critique…
I have recently complained about the use of LD50 values (the amount of a compound that kills half the exposed organisms after a short exposure) to compare and rank the toxicity of glyphosate. Maybe it’s pure coincidence, or maybe I just wanted to avoid some of the manuscripts waiting for me. But I came across…
For some reason, I recently managed to get into a discussion on glyphosate (the active ingredient of Roundup and other herbicidal products) on twitter. 140 characters might be sufficient for exchanging quick comments (and, obviously, for discussing US politics).
