Reducing risks of antibiotics to crop production requires land system intensification within thresholds

Abstract

Land system intensification has substantially enhanced crop production; however, it has also created soil antibiotic pollution, undermining crop production. Here, we projected soil antibiotic pollution risks to crop production at multiple geographical scales in China and linked them to land system intensification (including arable land expansion and input increase). Our projections suggest that crop production will substantially decrease when the soil antibiotic pollution risk quotient exceeds 8.30–9.98. Land systems explain most of the variability in antibiotic pollution risks (21–66%) across spatial scales. The convex nonlinearities in tradeoffs between antibiotic pollution risk and crop production indicate that vegetable and wheat production have higher thresholds of land system intensification at which the risk–yield tradeoffs will peak than do maize and rice production. Our study suggests that land system intensification below the minimum thresholds at multiple scales is required for acceptable antibiotic pollution risks related to crop yield reduction.

Ferrocenylselenoether and its cuprous cluster modified TiO2 as visible-light photocatalyst for the synergistic transformation of N-cyclic organics and Cr(vi)

“…TiO 2 was commercial P25 (75% anatase, 25% rutile). 1,2,3-Triselena [3] ferrocenophane fcSe 3 (fc = [Fe(h 5 -C 5 H 4 )(h 5 -C 5 H 4 )]) was prepared according to the literature methods. 32 Characterization 1 H NMR spectra were recorded on a Bruker DRX spectrometer (400 MHz) at room temperature.…”

“…1,2 With the rapid development of industry and global consumption, the N-cyclic organics are continuously discharged into the environment. 3,4 Due to their high stability and high chemical oxygen demand, it is difficult to rely solely on degradation by microorganisms under natural conditions. 5 These N-cyclic organics have become major harmful pollutants in soil and aquatic ecosystems, which have toxic effects on living organisms, including teratogenesis, carcinogenesis, and mutagenesis.…”

Review on Various Antibiotic Contamination in Natural Sources: Effects on Environment Including Animals and Humans

“…Veterinary professionals should be aware not to use antibiotics for growth promotion and work closely with farmers to ensure proper antibiotic use in animals. IV) Agriculture sector should follow the following steps to reduce contamination 94 : i) Responsible antibiotic use in livestock and aquaculture: a) Withdrawal Periods: Implement appropriate withdrawal periods to prevent antibiotic residues in animal products. ii) Waste management: a) Manure Handling: Properly manage animal waste to prevent antibiotic runoff into soil and water.…”

Quinolone Antibiotics Inhibit the Rice Photosynthesis by Targeting Photosystem II Center Protein: Generational Differences and Mechanistic Insights

“…10,11 A projection regarding Chinese farmlands suggested that antibiotic pollution could lead to a decline in crop yields, potentially undermining the contributions of human-led land management practices. 12 Therefore, investigating the influence of soil antibiotics on crop growth, particularly targeting photosynthetic efficiency, is crucial. Evaluating the implications of antibiotics for agricultural output, along with their impact on the carbon fixation capabilities of crops, is paramount for understanding the broader risks posed by these contaminants within the context of agroecosystems.…”

“…Crop immobility necessitates resilience against threats such as soil pollution, which can hinder growth and physiological development. − Notably, antibiotics have emerged as a group of pervasive contaminants. , With high production and consumption globally, these substances have manifested persistently in agricultural soils, reaching median concentrations of 5.20, 13.90, 27.93, and 43.75 μg/kg for macrolides, quinolones, sulfonamides, and tetracyclines, respectively . The ongoing deposition of livestock manure and municipal sewage has been linked to an upward trend in both the prevalence and levels of antibiotic contaminants detected. , A projection regarding Chinese farmlands suggested that antibiotic pollution could lead to a decline in crop yields, potentially undermining the contributions of human-led land management practices . Therefore, investigating the influence of soil antibiotics on crop growth, particularly targeting photosynthetic efficiency, is crucial.…”
