Microplastics in complex soil matrix: Recovery, identification and removal using micro nano techniques

Micro and Nano Engineering, Год журнала: 2024, Номер 22, С. 100237 - 100237

Опубликована: Янв. 4, 2024

Investigations on microplastic (MPs) particles in soils are extremely rare, and the published results often lack comparability due to different sampling, extracting, analytical approaches used. The current techniques for examining tiny MPs soil samples not particularly effective, but minor adjustments method combinations should be explored. complexity of matrix presents challenges developing a standardized approach characterizing removing them effectively, heterogeneity composition, variability their size/shape, interactions with particles, background contamination, methodological variations. This review focuses evaluating various methods extraction, purification, identification, measurement removal complex systems. A recommended methodology extracting from is proposed, aiming provide systematic recovery identification. Furthermore, article discusses sampling plans, drying sieving techniques, density separation methods, special emphasis photocatalytic removal. also addresses encountered such analyses suggests possible solutions, followed by future prospects. Additionally, importance environment highlighted, underscoring need effective methodologies tackling this pressing issue.

Optimisation of soil washing method for removal of petroleum hydrocarbons from contaminated soil around oil storage tanks using response surface methodology

Scientific Reports, Год журнала: 2023, Номер 13(1)

Abstract Total petroleum hydrocarbons (TPHs), which are often found in soil, water, sediments, and air. These compounds a type of pollutant that can have serious negative impact on living things human health. Soil washing method is remediation technique used to remove contaminants from the soil. This process involves use water or other solvents extract followed by separation disposal contaminated solution. research engineered effectiveness soil TPHs genuine, sullied sample. After analyzing physical chemical properties Box-Benken Design (BBD) was optimize variables influence process's effectiveness. A quadratic model suggested based BBD design, correlation coefficients, factors. The minimum, maximum mean removal during stages study were 63.5, 94.5 76.7%, respectively. between strong, as shown analysis variance (ANOVA), F-value (1064.5) P-value (0.0001), proposed highly significant. most effective (SWM) obtained with pH 7.8, liquid solid ratio 50:1, reaction time 52 min, surfactant concentration 7.9 mg kg −1 , three washings. rate 98.8% accomplished for this context. kinetic results indicate follows first-order kinetics (R 2 = 0.96). There not major difference efficiency temperature. heightened 0 150 rpm then remained steady. Introducing air flow increased removal, combination ultrasonic waves environment decreased amount times it needed be washed. An washed both physically chemically revealed substantial decrease elements.

Speciation, Mobilization, and Toxicity of Cadmium in Soil–Microbe–Plant System: An Overview

Опубликована: Янв. 1, 2024

The extensive application of cadmium (Cd) in various industrial products results worldwide contamination. In the first part this chapter, we mainly focus on species, mobility, and factors influencing Cd bioavailability soils. Furthermore, as interacts with essential cellular components adversely affecting microbial biomass diversity, also report sophisticated resistance mechanisms that provide microorganisms tolerance to Cd. Additionally, attention is paid highlighting rhizodegradation an interface between microbes rhizosphere can significantly influence increase nutrient uptake decline metal toxicity. particular, further discuss accumulation, toxicity, defense plants against

A novel heuristic tool for selecting the best upgrading conditions for the removal of potentially toxic elements by soil washing

Journal of Hazardous Materials, Год журнала: 2024, Номер 466, С. 133529 - 133529

Опубликована: Янв. 19, 2024

Here, we propose two-parameter penalized attributive analysis, PPAA-U, a novel heuristic tool for selecting the best upgrading conditions (BUCs) soil washing. Given multi-component feed and specific set of operating conditions, PPAA-U generates quality index based on how well recoveries key components are maximized while minimizing yield. We demonstrate, through calculation families curves, that this is related linearly to recovery inverse yield, meaning reducing yield values more important than maximizing recovery. To evaluate our method, electrostatic separation at 12 different voltages was carried out samples from an ex-industrial site in Spain. Values recovery, grade were analyzed using basic analysis with without target-to-distance correction. Both methods identified same optimal voltage, power correct high variation yields observed as divergence between results produced by each method low where these greatest. thus offers convenient washing optimization, suggest it could be applied successfully other industrial processes.

Ex-situ phytoextraction using Pteris vittata as a sustainable way to protect soil resource

Environmental Technology & Innovation, Год журнала: 2024, Номер 34, С. 103638 - 103638

Chemical industrial sites are potential land resources for urban construction, but the high concentration of heavy metals in soil restricts their timely redevelopment. Remediation treatment must be performed before reutilization these sites. Aiming to investigate Pteris vittata remove arsenic (As) from an As-contaminated chemical site, a 16-month ex-situ field experiment was conducted monitor dynamics growth and As uptake P. vittata. The shoot (pinnae petiole) biomass increased linearly with extension time, reached 1342 g m-2 at time ~16 months after transplantation. pinnae showed "large increase followed by small decrease" tendency its highest value 2550 mg kg-1 ~10 Compared control that removed 5.1 kg ha -1, addition potassium dihydrogen phosphate dose 600 (P2O5) or ammonium 300 removal ~13.0 ha-1. total cost phytoremediation 41.6 US$ t-1, being ~67% lower than common site remediation technologies such as washing. Ex-situ is suggested enable re-development resource sustainable protection resource.
