-The abstract mentions soil antibiotic levels exceeding 2.13×10^5 ng/g, but Figure 3 shows soil tetracycline concentrations maxing out around 10^2.3 ng/g. That’s a massive 1000x difference. Which number is correct, and does this error compromise your risk assessment?
-You propose a “planetary boundary for antibiotics” with a specific threshold of 153.7 μg/kg based on a single 2025 paper. Given the extreme variability in ecosystems and the lack of global consensus, isn’t this proposed boundary scientifically meaningless and dangerously premature for policy?
