Spatial estimation of veterinary antibiotics from husbandry to soil to river with resistance risk assessment in urban agglomerations.

Summary: Modern farming relies on antibiotics to keep livestock healthy, but these drugs don't stay on the farm. They travel through animal waste into the soil and eventually wash into local rivers, posing a serious environmental threat. Scientists have developed a new, highly accurate computer model using "Random Forest" technology to track this invisible path. By mapping exactly how antibiotics move from animals to waterways in urban areas like the Shandong Peninsula, this method helps identify pollution hotspots and assess the risk of creating drug-resistant superbugs.
