Special Issue Information

Dear Colleagues,

Environmental contaminants such as nanomaterials, synthetic drugs and chemicals, natural toxins, personal care products, pesticides, fertilizers, natural wastes, and heavy metals have apparent effects on the metabolome of living systems. Due to their sessile nature, plants are profoundly affected by these environmental contaminants. Ecotoxic compounds can exert changes in the primary (proteins, carbohydrates, organic acids, lipids, nucleotides, etc.) and secondary metabolite (flavonoids, alkaloids, phenolics, glucosinolates, tannins, glycosides, etc.) profiles of plants. To cope with environmental stressors, plants can produce various secondary metabolites. Metabolomics is the most robust approach to determining the modifications in the metabolite profile of living systems, and metabolic profiling is effectively determined with the help of mass spectrometry methods such as HPLC, NMR, and LC-MS. In the past decade, metabolomics has provided insight into the metabolisms of biological systems and the biochemistry of their ecology. Metabolomics attributes an improved knowledge of the impacts of these ecotoxicants on living systems, providing morphological and biological information in a high-throughput way. Furthermore, the progress in the instrumentation and evolution of databases will improve the utilization of metabolomics.

This Special Issue of Metabolites will be dedicated to the collection of both original research and review articles dealing with the application of metabolomics in ecotoxicology in laboratory and field-based investigations. This Special Issue focuses on recent applications of metabolomics to determine the environmental impacts of numerous environmental perturbations, comprising nanomaterials, pharmaceuticals, microbial and other natural contaminants, personal care products, fertilizers, pesticides, and heavy metals, on plant metabolomes. Manuscripts associated with other challenging problems are also highly desired.

Overall, combating food waste necessitates a multifaceted approach that includes education, infrastructure, and policy change. By working together to implement these strategies, we can help reduce the negative impacts of food waste and create a more sustainable and equitable food system. The sustained supply of nutrient-rich agrifood commodities is seriously threatened by inefficiencies caused by agricultural losses, which must be addressed. As per the statistical data given by the Food and Agriculture Organisation (FAO) of the United Nations, nearly 33.33% of the food that is produced for utilization is wasted and frittered away on a global level, which can be estimated as a loss of 1.3 billion metric tons per annum, which includes 30% cereals, 20% dairy products 35% seafood and fish, 45% fruits and vegetables, and 20% of meat. This review summarizes the various types of waste originating from various segments of the food industry, such as fruits and vegetables, dairy, marine, and brewery, also focusing on their potential for developing commercially available value-added products such as bioplastics, bio-fertilizers, food additives, antioxidants, antibiotics, biochar, organic acids, and enzymes. The paramount highlights include food waste valorization, which is a sustainable yet profitable alternative to waste management, and harnessing Machine Learning and Artificial Intelligence technology to minimize food waste. Detail of sustainability and feasibility of food waste-derived metabolic chemical compounds, along with the market outlook and recycling of food wastes, have been elucidated in this review.

In plant biology, metabolomics is often used to quantitatively assess small molecules, metabolites, and their intermediates in plants. Metabolomics has frequently been applied to detect metabolic alterations in plants exposed to various biotic and abiotic stresses, including pesticides. The widespread use of pesticides and agrochemicals in intensive crop production systems is a serious threat to the functionality and sustainability of agroecosystems. Pesticide accumulation in soil may disrupt soil–plant relationships, thereby posing a pollution risk to agricultural output. Application of metabolomic techniques in the assessment of the biological consequences of pesticides at the molecular level has emerged as a crucial technique in exposome investigations. State-of-the-art metabolomic approaches such as GC–MS, LC–MS/MS UHPLC, UPLC–IMS–QToF, GC/EI/MS, MALDI-TOF MS, and 1H-HR-MAS NMR, etc., investigating the harmful effects of agricultural pesticides have been reviewed. This updated review seeks to outline the key uses of metabolomics related to the evaluation of the toxicological impacts of pesticides on agronomically important crops in exposome assays as well as bench-scale studies. Overall, this review describes the potential uses of metabolomics as a method for evaluating the safety of agricultural chemicals for regulatory applications. Additionally, the most recent developments in metabolomic tools applied to pesticide toxicology and also the difficulties in utilizing this approach are discussed. Full article
