“…As larger plastic debris gradually degrades into smaller particles over time, pellet-shaped MPs become prevalent in soil [ 43 ]. Fibers, primarily detected in agricultural soils in Bangladesh, originate from diverse sources like synthetic textiles and plastics, raising environmental concerns due to their widespread dispersion [ 44 ]. These fibers infiltrate agricultural soil through pathways such as irrigation water, wind deposition, and erosion, potentially affecting soil health and ecosystems.…”

Microplastic contamination in agricultural soil is an emerging problem worldwide as it contaminates the food chain. Therefore, this research investigated the distribution of microplastics (MPs) in agricultural soils without mulch at various depths (0–5, 5–10, and 10–15 cm) across different zones: rural, local market, industrial, coastal, and research areas. The detection of MP types and morphology was conducted using FTIR and fluorescence microscopy, respectively. Eight types of MPs were identified, including high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyvinyl fluoride (PVF), polyvinyl alcohol (PVA), and polytetrafluoroethylene (PTFE), with concentrations ranging from 0.6 ± 0.21 to 3.71 ± 2.36 MPs/g of soil. The study found no significant trends in MP concentration, with ranges of 0–2.1 ± 0.38, 0–2.87 ± 0.55, and 0–2.0 ± 0.34 MPs/g of soil at depths of 0–5 cm, 5–10 cm, and 10–15 cm, respectively. The highest MP quantity was recorded at 8.67 in coastal area, while the lowest was 6.44 in the local market area. Various MP shapes, e.g., fiber, film, pellet, fragment, and irregular, were observed across all layers. PCA suggested irrigation and organic manure as potential sources of MPs. The estimated concentrations of MPs possessed low non-carcinogenic and carcinogenic risks to the farming community of Bangladesh.

“…Another area of attention is the possible presence of microplastics in textile sludge, which could pose a risk when used in agricultural applications. The study of Hossain et al [45] investigated this relationship in Bangladesh soils near textile industries, and although MPs were detected in both soils and textile sludges, they could not find a causal relationship to the use of sludges, thus pointing to other possible sources of MPs. Still, the study calls for the detection and removal of MPs in textile sludges before they are used in agricultural settings, which evidently requires strong regulatory programs to ensure these risk-mitigating steps are widely implemented.…”

The textile sector of Bangladesh has positively contributed to a significant impact on its national economy and employment opportunities due to its rapid growth. The increasing number of wet processing units has led to a growing amount of wastewater volume as well as textile sludge (a byproduct of wastewater or effluent treatment plants). In 2015, the government of Bangladesh instituted the “Bangladesh Standards and Guidelines for Sludge Management”. Therefore, this case study aimed to assess these standards’ impact on the textile industry’s sludge management practices, informing academic scholars of the research opportunities available, and serving as a policymaking tool for various other South Asia and Southeast Asia economies. The sludge management situation of thirty-six industries (namely, twelve dyeing, twelve printing, and twelve washing) was herein assessed through a self-administered questionnaire survey of respondents from the respective ‘Top Management’ and ‘Environmental Chemical Responsible’ (ECR) departments. Among the findings, the assessment revealed that neither treatment procedures nor reuse and recycling activities are present for sludge management in any of the studied industries. The responsible personnel from the textile industries have not undergone any level of technical training, and 41.7% of the printing industries still dump sludge in the open environment. The majority (83%) of stakeholders are unaware of the dangers and potential effects of improper sludge treatment. The key factors—responsibility, knowledge, behavior, and consideration—analyzed in this study, together with the study’s recommendations, will be a vital step forward in formulating policy advocacy for hazardous sludge management within the textile sector of Bangladesh.

“…Despite these findings, human understanding of soil pollution by MPs is still limited. The global surge in plastic waste is a growing environmental challenge, with approximately 79% [42] of this waste accumulating in landfills and other terrestrial compartments, including agroecosystems [43][44][45][46]. This emphasizes the pressing need to investigate and comprehend the extent of MP pollution in soil, as it plays a crucial role in agricultural and ecological systems [47].…”

Environmental pollution caused by microplastics has evolved into a global concern; however, limited knowledge exists about microplastics in soils due to the absence of standardized extraction methods. This research aimed to develop an inexpensive, rapid method with user-friendly and environmentally sustainable outcomes for microplastics retrieval. Three salt solutions (Sodium Chloride, Magnesium Sulfate, Sodium Hexametaphosphate) and an oil solution (canola oil) underwent evaluation for microplastics extraction through the flotation process due to the density and oleophilic properties of plastics. Four widely used plastic types, obtained through fragmentation using a grinding mill from clean new plastic containers or membranes, were subjected to analysis. The experimental procedures for microplastics retrieval varied among the evaluated solutions. Through a comprehensive multicriteria analysis, the saturated Sodium Chloride solution emerged as the optimal scenario for microplastics extraction, followed closely by the canola oil scenario. The recovery method utilizing Sodium Chloride demonstrated economic feasibility, safety, and reliability. This study provides valuable insights into an effective and sustainable approach for mitigating microplastic pollution in soil, offering a promising avenue for future environmental conservation efforts.
