Non-target analysis of organic waste amended agricultural soils: Characterization of added organic pollution

Amendment of soil with organic urban and animal wastes can keep arable fertile without the need for synthetic fertilizers. However, pollutants present in these types waste might be carried into unintended consequences environment. We studied an experimental agricultural plot, which had been amended either inorganic fertilizers, human urine, manure, or wastewater treatment sludge at very high rates. applied chemical non-target analysis to characterize micropollutants, intending compare treatments highlight suspects environmental concern. Soil samples were prepared by pressurized liquid purified solid-phase extraction before nanoflow ultra-high performance chromatography coupled high-resolution Orbitrap tandem mass spectrometry. Automated elucidation two spectral libraries, multiple large databases NORMAN suspect lists was able annotate (level 3 level 2) ? 20% 2306 detected features. A following principal component- differential-analysis could separate groups’ pollution profiles relative abundance From cattle natural compounds such as bile acids steroids found. Human urine led common pharmaceuticals metoprolol propranolol. The highest number added sludge, 25 significant contaminants, spanning blood pressure regulators, antidepressants, sleep medication. Furthermore, using Kendrick defect plots, a series polypropylene glycols revealed soil. Non-target appears promising method soils.
