“…Recent advances in toxicity studies revealed that MPs not only cause physical and mechanical damages, but also induce oxidative damage, gut dysbiosis, intestinal barrier dysfunction, neurotoxicity, energy‐related changes, and even gene expression . It is worth noting that, MPs pollution in the terrestrial environment may be more even worse than in the marine environment because of the plastic particles in the industrial production and the use of agricultural plastic film directly . MPs have brought dangers to soil animals and might threaten human health via the food chain or other ways .…”

Microplastics (MPs) pollution is a global paradigm that raises concern in relation to environment and human health. In order to investigate the molecular toxicity mechanisms of MPs, transcriptomic analyses were performed on in vitro Caco‐2 cell model. After observing that polystyrene microplastics (PS‐MPs) decreased cell viability in a dose‐dependent manner, the responsible genes and involved pathways that might make contribution to PS‐MBs‐induced toxicity to Caco‐2 cells were identified with Illumina RNA seq. A total of 442 genes including, 210 up‐regulated ones and 232 down‐regulated ones, showed differential expression after treatment by PS‐MPs with a concentration of 12.5 mg L−1 or 50.0 mg L−1 for 24 hours. Gene Ontology (GO) annotation enriched unigenes can be grouped into three separated clusters: cellular component (CC), biological process (BP), and molecular function (MF). The dominate pathways related to NF‐κB, MAPK signaling, cytokine‐cytokine receptor interaction, and toll‐like receptor were strongly influenced by PS‐MBs. These pathways are involved in modulating cell inflammatory and proliferation. The qPCR were applied to investigate the transcriptional level of five proliferation related genes (Ras, ERK, MER, CDK4, Cyclin D1) and four inflammation related genes (TRPV1, iNOS, IL‐1β, IL‐8), and the results were consistent with RNA‐seq data. This study has provided new insight into the understanding of the toxicity effects of PS‐MBs‐induced intestinal inflammatory diseases.

“…It is necessary to emphasize the increasing problems caused in the environment by the plastics. For example, [33] indicated that the presence of PE in horticultural soils in Argentina can represent around 10% of the soil and [34] affirmed that the amount of plastic waste in an average vegetable field of China could reach 317.4 kg ha −1 . Although no similar data have been found for Europe, there is strong evidence that the presence of plastic residues also affect the soil quality.…”

Economic Evaluation of Biodegradable Plastic Films and Paper Mulches Used in Open-Air Grown Pepper (Capsicum annum L.) Crop

et al. 2019

Black polyethylene (PE) is the most common mulching material used in horticultural crops in the world but its use represents a very serious environmental problem. Biodegradable films and paper mulches are available alternatives but farmers are reluctant to adopt them because of their high market prices. The aim of this paper is to evaluate the economic profitability of eight biodegradable mulching materials available for open-air pepper production. The economic evaluation is based on a four-year trial located in a semi-arid region of Spain. Three scenarios of PE waste management are examined: (i) absence of residues management, (ii) landfill accumulation, and (iii) total recycling. The inclusion of the costs of waste management and recycling under the current Spanish legislation only reduced the final net margin by 0.2%. The results show that an increase in subsidy rates of up to 50.1% on the market price would allow all biodegradable films to be economic alternatives to PE. The study supports the mandatory measures for the farmers to assume the costs of waste management and recycling. Despite savings in field conditioning costs, high market prices of biodegradable materials and papers are not compensated by the current level of subsidies, hampering their adoption in the fields.

“…The challenge for the agricultural sector is to increase food supply while ensuring that sustainable farming systems are used and the damage to the soil, water and air is minimized . The use of polymeric materials from non‐renewable sources is common in high‐intensity agriculture, resulting in the contamination of productive agricultural soils, the accumulation of large amounts of waste, as well as the release of toxic additives into the soil …”

“…1 The use of polymeric materials from non-renewable sources is common in high-intensity agriculture, resulting in the contamination of productive agricultural soils, 2 the accumulation of large amounts of waste, 3 as well as the release of toxic additives into the soil. 4 The permanence of the unrecovered used plastic in the soil alters the soil quality. It accelerates carbon and nitrogen metabolism, which leads to water repellency, increasing the risk of mycotoxin formation and, consequently, climate-relevant gases.…”

Starch–gelatin film as an alternative to the use of plastics in agriculture: a review

et al. 2019

BACKGROUND The technological advances in agriculture, driven by the increased demand for food attributed to population growth, have led to the search for technologies that allow greater control over the variables that interfere in crop yield. Several techniques stand out for optimizing yield capacity, including cultivation in a protected environment, mulching and low tunneling. To expand the use of these techniques, synthetic petroleum‐based polymers are employed due to their low cost, easy processing, and lightness. However, they take a long time to degrade, and, since they are discarded at the end of each cycle of cultivation, end up accumulating in the environment causing irreversible damage. RESULTS The use of biodegradable films, made of starch and/or a protein source such as gelatin, has been studied as a promising alternative. Both stand out because of their film‐forming ability, and because they come from abundant sources and are biodegradable. CONCLUSION This study aimed to review the current findings on starch and gelatin films that can be used as alternatives to conventional plastics in agricultural crops. © 2019 Society of Chemical Industry
