ABSTRACT Extensive usage of agricultural plastic film correspondingly leads to excessive residues microplastics (MPs). MP accumulation alters soil hydraulic properties and water flow. However, little is known about the combined effects concentration particle size on hydrological properties, a numerical approach for modelling infiltrated flow has not been well developed. Hence, we determined affected by established model suitable MP‐contaminated soils. Quantitative findings indicated that saturated conductivity soil–MP mixture was 10.8%–50.0% smaller than pure soil, which decreased increased with increase in size, respectively. The always had significant influences conductivity; contrast, generated under condition small size. Besides, higher or MPs led weaker water‐holding capacity, residual content 0.6% – 41.5% 0.2% 11.6%, Furthermore, presence inhibited infiltration, wetting front migration rate cumulative infiltration 7.1% 29.4% 4.7% 21.7%, respectively, Correlation analysis negatively correlated saturated/residual moisture, infiltration; addition, conductivity, compared (15.63%), (46.28%) played major role response movement changes external environment.

Life cycle assessment of filament production in distributed plastic recycling via additive manufacturing

Cleaner Waste Systems, Journal Year: 2023, Volume and Issue: 5, P. 100100 - 100100

Published: May 24, 2023

Distributed recycling via additive manufacturing (DRAM) emphasizes an emerging approach to locally recycle waste plastic by 3D-printing it into valuable products. Although major progress has been reported in the last decade validate technical feasibility, and economic viability of DRAM as unitary operation, environmental evaluation this is still at its early stage a distributed network. The purpose study evaluate impact unit baseline scenario, compared two scenarios virgin supply chain filament used printing process. To achieve goal, comparative performance using life cycle assessment (LCA) performed estimate multidimensional potential impacts recycled polylactic acid (PLA). takes place physical demonstrator developed university Nancy, France. Four categories were considered: climate change, eutrophication (Freshwater Marine), resource depletion (Fossil Water), ion radiation. For first three categories, results demonstrate minimum 97% reduction chain. However, terms radiation, amount emissions approximately 2.8 times higher than that scenario. This increase mainly due specific situation France, where most energy generated nuclear means. aims expand on network system better understand implementation these systems for management, which can help extend lifetime material. findings provide overview benefits disadvantages developing particular context.

Blueprint for the design, construction, and validation of a plastic and phthalate-minimised laboratory

Journal of Hazardous Materials, Journal Year: 2024, Volume and Issue: 468, P. 133803 - 133803

Published: Feb. 15, 2024

Micro and nanosized plastics (MNPs), a range of associated additive chemicals, have become pervasive contaminants that humans the environment are exposed to everyday. However, one principal challenges in their analysis is adequate strategies minimise background contamination. Here blueprint for specialised additive-minimised clean room laboratory built this purpose presented. Common construction materials (n = 23) were tested, including acoustic baffles, ceiling materials, floor glazing rubber, silicone sealant. The % polymer content ranged from 2-76% w/w while sum concentration six phthalates 0.81 (0.73-0.86) 21000 (15000-27000) mg/kg, assigning many these as inappropriate use environment. final design consisted three interconnected rooms, operated under positive pressure with inner rooms constructed almost entirely stainless steel. Background concentrations MNPs new compared two Physical Containment Level 2 (PC2) environments, reduced by > 100 times up 120 times. This study reports first known its kind provides reference future research.

Nitrogen fertilization and arbuscular mycorrhizal fungi do not mitigate the adverse effects of soil contamination with polypropylene microfibers on maize growth

Soil contamination with microplastics may adversely affect soil properties and functions consequently crop productivity. In this study, we wanted to verify whether the adverse effects of in on maize plants (Zea mays L.) are due a reduction nitrogen (N) availability reduced capacity establish symbiotic relationships arbuscular mycorrhizal (AM) fungi. To do this, performed pot experiment which clayey was exposed two environmentally relevant concentrations polypropylene (PP; one most used plastic materials) microfibers (0.4% 0.8% w/w) or without addition N fertilizer inoculation AM The began after had been incubated at 23 °C for 5 months. PP considerably root shoot biomass, leaf area, uptake, content tissue. increased concentration soil. Adding did not alleviate detrimental plant growth, suggests that other factors besides played major role. Similarly, although presence inhibit colonization by fungi (no differences were observed trait between uncontaminated PP-contaminated soils), fungal inoculum failed mitigate negative impact growth. Quite opposite: mycorrhization further biomass accumulation. Undoubtedly, much research remains be done shed light mechanisms involved determining behavior microplastic-contaminated soils, likely complex. This is priority given magnitude its potential implications human environmental health.
