The concentrations and distributions of polychlorinated dibenzo-p-dioxins(PCDDs), polychlorinated dibenzofurans(PCDFs), and polychlorinated biphenyls(PCBs) in the whole blood and meat of eight typical edible animals(chicken, donkey, horse, cattle, rabbit, sheep, duck,and pig) were illustrated. Total concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs) and PCBs(on a basis of liquid volume) in animal bloods were 142-484 pg/L and 46-62 ng/L, respectively. Total concentrations of PCDD/Fs and PCBs(on a basis of dry weight(dw) and lipid weight(lw)) in animal meat samples were 0.47-1090 pg/g dw(0.47-4513 pg/g lw) and 7.2-23 ng/g dw(10-776 ng/g lw), respectively. TEQs for both PCDD/Fs and PCBs in animal blood and meat samples were(67 ± 27) pg/L and(5.3 ± 14) pg/g dw(24± 56 pg/g lw), respectively. Besides, the dietary intakes of PCDD/Fs and PCBs were also estimated. Chicken and pig contributed more TEQs than other animals. Chicken contributed the most(95%) with high toxicity, followed by pig(3.4%) with high consumption. The dietary intake of chicken might pose risks to consumers who prefer to eat chicken products, who should comprehensively consider the essential nutrients and contaminants in food during dietary intake.

Urbanization,population growth,and the accelerating consumption of food,energy,and water(FEW)resources bring unprecedented challenges for economic,environmental,and social(EES)sustainability.It is imperative to understand the potential impacts of FEW systems on the realization of the United Nation’s Sustainable Development Goals(SDGs)as the world transitions from natural ecosystems to managed ecosystems at an accelerating rate.A major obstacle is the complexity and emergent behavior of FEW systems and associated networks,for which no single discipline can generate a holistic understanding or meaningful projections.We propose a research enterprise framework for promoting transdisciplinarity and top-down quantification of the interrelationships between FEW and EES systems.Relevant enterprise efforts would emphasize increasing FEW resource accessibility by improving coordinated interplays across sectors and scales,expanding and diversifying supply-chain networks,and innovating technologies for efficient resource utilization.This framework can guide the development of strategic solutions for diminishing the competition among FEW-consuming sectors in a region or country,and for minimizing existing inequalities in FEW availability when a sustainable development agenda is implemented.

Objective The primary objective of this study was to examine the validity and reliability of a semi-quantitative food frequency questionnaire(FFQ) among Chinese children aged 12-17 years. Methods A semi-quantitative 72-food item FFQ was developed for children aged 12-17 years. The reliability and validity of this FFQ were evaluated against 24-h dietary recalls(24 h DRs) to measure the consumption of foods and nutrients. We administered two FFQs and three DRs to children(N = 160) over a period of 1 month to evaluate the reliability and validity. Reliability was examined by quartile agreement and intraclass correlation coefficients(ICCs), and validity was examined by quartile agreement, Bland-Altman plots and correlation with DRs. Results For reliability, the ICCs between the two FFQs ranged from 0.21 to 0.76 for foods and nutrients, and the quartile agreement ranged from 70.0% to 95.0% in the same or adjacent quartiles. Spearman’s correlation coefficients of foods and nutrients between the second FFQ and the 24 h DRs ranged from-0.04 to 0.59. The Bland-Altman plots demonstrated good agreement across the range of intakes among nutrients. The quartile agreement ranged from 50.0% to 100.0%, with infrequent misclassification. Conclusion The FFQ assessment of dietary intakes demonstrated acceptable relative validity and high reproducibility for Chinese children aged 12-17 years.

Background:Antimicrobial resistance(AMR)is one of the greatest threats to animal and public health.Here,we conducted a dynamic surveillance of Escherichia coli on Chongming Island in Shanghai during 2009-2021 to identify the characteristics and trends of Chongming’s AMR pandemic.Methods:Rectal(cloaca)swabs from four poultry and nine swine farms(Chongming Island,2009-2021)were collected for E.coli strains acquisition.The micro-broth dilution method was used to test antimicrobial susceptibility of E.coli isolates against 10 antimicrobial classes including 15 antimicrobials.Utilizing generalized linear mixed models(GLMMs)and co-occurrence analyses,we further explored the multiple-drug-resistance(MDR)combinations and dynamic patterns of E.coli over 10 years in two food animals.Results:Total of 863 MDR isolates were found among 945 collected E.coli isolates,337 from poultry and 608 from swine.Both isolates exhibited high resistant rates(>70%)to tetracyclines,phenicols,sulfonamides,penicillins,and aminoglycosides(only in swine).The resistant rates of swine isolates to penicillins,aminoglycosides,tetracyclines,phenicols,and polymyxins were significantly higher than those of poultry isolates,whereas resistance to fluoroquinolones was reversed.Resistance to polymyxins decreased similarly in swine(42.4%in 2009 to 0.0%in 2021)and poultry isolates(from 16.5%to 0.0%).However,resistance to other seven antimicrobial classes(excluding carbapenems and penicillins)declined dramatically in swine isolates,particularly fluoroquinolones(from 80.5%to 14.4%),and tendencies of resistance to the seven classes showed markedly divergent patterns in poultry isolates.Using Poisson GLMMs,the AMR carriage since 2016 was significantly lower than that of 2009(odds ratio<1),indicating a decline in the risk of MDR emergence.Furthermore,despite the highly diverse MDR profiles,co-occurrence analysis identified two prominent MDR clusters of penicillins-phenicols-fluoroquinolones in poultry and aminoglycosides-tetracyclines-sulfonamides-phenicols in sw

Is our food safe and free of the crisis of antibiotics and antibiotic resistance (AR)?And will the derived food waste (FW) impose AR risk to the environment after biological treatment? This study used restaurant FW leachates flowing through a 200 tons-waste/day biological treatment plant as a window to investigate the fate of antibiotics and antibiotic-resistance genes (ARGs) during the acceptance and treatment of FW.Sulfonamides (sulfamethazine,sulfamethoxazole) and quinolones (ciprofloxacin,enrofloxacin,ofloxacin) were detected during FW treatment,while tetracyclines,macrolides and chloramphenicols were not observable.ARGs encoding resistance to sulfonamides,tetracyclines and macrolides emerged in FW leachates.Material flow analysis illustrated that the total amount of antibiotics (except sulfamethazine) and ARGs were constant during FW treatment processes.Both the concentration and total amount of most antibiotics and ARGs fluctuated during treatment,physical processes (screening,centrifugation,solid-liquid and oil-water separation) did not decrease antibiotic or ARGs concentrations or total levels permanently;the affiliated wastewater treatment plant appeared to remove sulfonamides and most ARGs concentrations and total amount.Heavy metals Ni,Co and Cu were important for disseminating antibiotics concentrations and MGEs for distributing ARGs concentrations.Humic substances (fulvic acids,hydrophilic fractions),C-associated and N-associated contents were essential for the distribution of the total amounts of antibiotics and ARGs.Overall,this study implied that human food might not be free of antibiotics and ARGs,and FW was an underestimated AR pool with various determinants.Nonetheless,derived hazards of FW could be mitigated through biological treatment with well-planned daily operations.

Stereoscopic porous carbons have shown good potential in humic acid(HA) removal. In this work, a novel stereoscopic porous activated carbon(SPAC) was designed and synthesized via the self-assembly of a hydrogel based on food waste during in-situ polymerization, vacuum drying, carbonization, and activation. Then, the SPAC was functionalized with 3-aminopropyltriethoxysilane(APTES) and the adsorption behavior of the modified SPAC(SPAC-NH_2) was studied systematically. The effects of pH, contact time, initial concentration of HA, and adsorbent dose were investigated, showing that optimal HA removal efficiency(>98.0%) could be achieved at an initial HA concentration of 100 mg/L. The experimental adsorption isotherm data was fitted to the Langmuir model with a maximum adsorption capacity of 156.0 mg HA/g SPAC-NH_2. Analysis of the mechanism indicated that the removal of HA was mainly realized through the amidization reaction between the \COOH groups of HA and the \NH_2 groups of APTES. All of the above results showed that SPAC-NH_2 powder is an efficient,eco-friendly, and reusable adsorbent which is suitable for the removal of HA from wastewater.
