Heavy metal (HM) pollution in agricultural soils represents a hidden danger to food security worldwide. In this paper, the spatio-temporal trends of heavy metals from eight countries and 50 soil samples farmland were evaluated through combination field surveys meta-analysis provide comprehensive report on pollution. The analysed using inductively coupled plasma–mass spectrometry (ICP-MS) (Perkin Elmer Nixon 300Q). contamination factor (CF) load index (PLI) calculated. results CF indicate extreme for Cr, suggesting ecotoxicological effects, while PLI values range baseline moderate Cd, Hg, Cu, Zn, Ni, except which shows very high pollution, that oils have undergone some form deterioration. reviewed articles published between 2010 2023 showed increasing all HMs. weighted mean As, Ni 0.0-222.7, 0.08-289.2, 0.03-193, 2.94-198.1, 0.0-771.1, 0.0-231, 1.71-99.75.6 mg/kg, respectively. Zn As exceeded two three times China National Environmental Monitoring Centre (CNEMC) European Union's most cited guideline (MEF), rock crust guideline. correlation matrix heatmap revealed highly positive Cr (R2 = 0.66), these elements same source are likely prevalent soils. spatial origin publications reveals 82% studies followed by South Africa Italy accounting 4% respectively Nigeria, Egypt, Morocco, Iran, Turkey account 2% each. findings study important implications environmental regulation protection Unlike previous often adopt "silos" method, highlights nexus approach integrates both experimental could establish more understanding

The quality and safety of agricultural products are paramount importance in ensuring the health food supply chain. Additionally, composition trace elements significantly influence their nutritional value. Therefore, need for rapid accurate analysis techniques product is particularly crucial. In current landscape evolving compositional technologies, Laser-Induced Breakdown Spectroscopy (LIBS) technology emerging as a promising analytical tool with broad applications testing. Its characteristics being rapid, real-time, capable simultaneous detection multiple provide an efficient reliable means assessing quality, monitoring safety, tracing origin products. This expected to play significant role controlling managing industry chain can offer consumers safer healthier paper provides overview research status recent developments LIBS testing years. Based on landscape, challenges opportunities applying fields such assessment, soil analysis, assessment crop nutrition, plant diseases, identification varieties have been evaluated. Moreover, recommendations further expanding application sector proposed.

Knowing the exact heavy metal load of recycled plastics is important for their risk assessment. We therefore established a novel strategic hierarchy testing plastics. For preliminary screening unusually high elemental loads, laser-induced breakdown spectroscopy (LIBS) suggested, while inductively coupled plasma-mass spectrometry (ICP-MS) or electrothermal atomic absorption (ETAAS) are used quantification. The contents ten regulated elements (Hg, As, Cd, Cr, Co, Cu, Se, Pb, Sn and Ni) in post-consumer (PCR), post-industrial (PIR), virgin polypropylene (PP) were thus determined. Concentrations PCR mostly found to be two orders magnitude smaller than threshold non-food applications. Cu was most abundant with 18.7±6.1 mg/kg. Concentration variations approx. 30 %. within batch, between batches, slightly higher 40 % observed. Moreover, concentration patterns PIR differ significantly. This strategy may enhance applicational possibilities PCR.

Enhancing soil organic carbon (SOC) content in farmland is crucial for quality maintenance and food security. However, the relationship between crop rotation SOC sequestration remains unclear. We used sample data on SOC, collected September of every year, from cultivated land monitoring 2017 to 2021, combined with spatially extracted planting system information, focused effects wheat–maize Sushui River Basin. An analysis variance (ANOVA) indicated that was only significantly different wheat monoculture maize monoculture. Among three cropping systems, did not show absolute superiority.
