The impact of heavy metal presence in soil on cereal crops is a growing concern, posing significant challenges to global food security and environmental sustainability. Cereal crops, vital sources nutrition, face the risk contamination with toxic metals released into environment through human activities. This paper explores key aspects requiring thorough investigation foster innovation understand intricate interactions between cereals. Visible symptoms physiological changes resulting from contamination, such as chlorosis stunted growth, demand further research devise targeted mitigation strategies sustainable agricultural practices. Root barrier formation, mycorrhizal symbiosis, metal-binding proteins emerge critical defence mechanisms for combating stress, offering opportunities developing metal-tolerant varieties. Research bioavailability safety implications grains safeguard health. reveals that multidisciplinary collaboration cutting-edge technologies are essential promoting beyond state art elucidating mitigating impacts crops. Genetic breeding approaches show promise varieties, while agronomic practices amendments can reduce toxicity.

The concept of food waste and food loss prevention and measuring tools

Waste Management & Research The Journal for a Sustainable Circular Economy, Journal Year: 2024, Volume and Issue: 42(8), P. 651 - 669

Published: March 21, 2024

Food waste (FW) has become a global concern, with an estimated 1.3 billion tonnes lost annually, costing about $1 trillion. Environmental and social consequences of FW are significant, contributing to 6% European Unions' greenhouse gasemissions affecting food security. occurs is complex issue occurring at various stages the supply chain (FSC) influenced by multiple factors such as infrastructure, available knowledge socio-economic conditions. Developed countries more prevalent consumption stage, whereas in developing losses occur agricultural production, post-harvest distribution stage. Accurate quantification across crucial monitoring key performance indicators helps identify areas for improvement. The Union mandates measurement, aligning sustainable development goals, emphasizing need effective prevention measures. Preferred Reporting Items Systematic Reviews Meta-Analyses approach was utilized conduct systematic literature review on (KPIs) tools. research identified 22 KPIs, categorized into three levels FSC: primary, secondary tertiary. most common KPIs included per capita, portion percentage. study further discusses measures essential tools addressing throughout chain.

Revealing the Combined Effects of Microplastics, Zn, and Cd on Soil Properties and Metal Accumulation by Leafy Vegetables: A Preliminary Investigation by a Laboratory Experiment

Soil Systems, Journal Year: 2023, Volume and Issue: 7(3), P. 65 - 65

Published: July 17, 2023

A pot experiment was carried out to investigate the effects of polyethylene (PE), a broadly utilized polymer type, on soil properties and lettuce growth. Two Zn- Cd-contaminated samples were obtained from urban rural areas Greece, respectively. PE fragments (<5 mm) added at different concentrations (2.5%, 5% w/w). Lettuce seeds then planted in pots completely randomized experiment. Plant growth patterns tissue metal accumulation investigated. The presence soils resulted reduction pH, significantly enhanced organic matter content, increased cation-exchange capacity. availability both metals also increased. Metal migration plant determined using appropriate tools indexes. higher concentration detected roots compared with that edible leaves. MPs (2.5% w/w) amount available Zn more than Cd highly contaminated soils. When agricultural soil, leaves by 9.1% 21.1% (5% Considering microplastics cannot be easily quickly degraded, fact less toxic is plants encouraging.

Over the last few decades, different types of plastics have been found in soil with documented or potential negative effects on environment, flora and fauna inhabiting soils, subsequently human health. This article is a global review consequences interactions soil, plants, microbes, organic inorganic pollutants depending land use. It focuses various polyethylene, widely used material strong presence both agricultural urban soils. Although chemical formula (C2H4)n remains same its classifications, behavior polyethylene varies directly depends density, branching, crystallinity, relative molecular mass, resulting many differences properties but also two main forms low high density. However, beyond composition plastics, climatic conditions that apply rural areas determine degree corrosion as well their shape size, affecting reactions indirectly affect them. In plants microbiome present mainly rhizosphere seem to dramatically influence where interaction all these parameters leads changes availability nutrients (phosphorus potassium), percentage matter nitrogen cycle. increase temperature decrease humidity are adsorption heavy metals surface plastics. considered inevitable, perhaps more thorough study them will lead reduction risks pollution environments. research provides promising perspective contribution MP PEs sustainable management systems.

Abstract The plant Silybum marianum (L.) Gaertn. has been used in a preliminary study to investigate its phytoremediation potential moderately and heavily Cd-polluted Greek soils. For this purpose, pot experiment was carried out using four soil treatments, two from agricultural urban areas, contaminated with 3 30 mg of Cd per kg soil. modified Bureau Community Reference (BCR) fractionation method determine levels the fractions. water-soluble, available-DTPA extractable, total pseudo-total concentrations were also evaluated attempts find relationships between fractions parts cultivated plants made. Significant correlations among fractions, parts, physicochemical parameters obtained discussed. High translocation accumulation rates observed mainly root lower part stems, while flowers seeds no detected, leading conclusion that high-value product contained maintains quality is free contaminants. results are satisfactory indicating as promising for remediation practices Cd-contaminated Mediterranean soils, promoting principles circular economy.
