Solar-driven photothermal water evaporation is considered an elegant and sustainable technology for freshwater production. The existing systems, however, often suffer from poor stability biofouling issues, which severely hamper their prospects in practical applications. Conventionally, materials are deposited on the membrane supports via vacuum-assisted filtration or dip-coating methods. Nevertheless, weak inherent material-membrane interactions frequently lead to durability, material layer...
Recently, soil contamination with microplastics has emerged as a serious global environmental concern that necessitated more research on their potential impacts biota. We investigated the acute and chronic toxicity of 2 different polystyrene microplastics, pure versus commercial (0-0.5% w/w in soil; sized 65-125 µm) earthworm mortality, reproduction, genotoxicity. Whereas showed no terms reproduction was adversely affected both parents (F0) first filial generation (F1) earthworms, >50%...
The prevalence and adverse impacts of microplastics requires the identification science-based abatement measures. Electrocoagulation treatment is a cost-effective oxidation process that removes numerous pollutants, including to some extent, microplastics. performance custom-built electrocoagulation reactor was determined by calculating removal efficiency. effects on polymer types (polyamide (PA), polyethylene (PE), terephthalate (PET) polypropylene (PP)) shapes (fibres fragments) were...
Microplastics are introduced into the agroecosystem through application of wastewater and biosolids, plastic mulch films, greenhouse materials, soil conditioners. accumulation can alter ecosystem cause adverse effects on organisms. Therefore, this study for first time evaluated acute chronic pure commercial polyethylene microplastics (PEMP) at environmentally relevant concentrations (0.01–0.5%) earthworms (Eisenia fetida). Exposure to PEMP in 0.5 % concentration caused ≥70% reduction...
In developing and developed countries, urban gardening has increasingly become an integral part of local food systems for good quality produce, enhanced health sustainability. There are few gardens with naturally perfect soils growing plants. However, the poor texture fewer nutrients can be improved by different types organic amendments such as composts, garden potting mixes that commercially available in consumer markets worldwide to promote healthy plant growth. this study, we assessed 19...
The phytoremediation technique has been demonstrated to be a viable option for the remediation of polycyclic aromatic hydrocarbons (PAHs) contaminated sites. This study evaluated potential applicability plants with C3 and C4 carbon fixation pathways recalcitrant high molecular weight (HMW) PAHs soil. A 60 120-day greenhouse was conducted which showed higher degradation HMW in soil grown when compared plants. Also, no were detected maize cobs, sunflower, wallaby, Sudan grass seeds at end...
Abstract Pyrosequencing of 16S ribosomal RNA (rRNA) was employed to characterize bacterial communities colonizing the rhizosphere plants with C3 and C4 photosynthetic pathways grown in soil contaminated polycyclic aromatic hydrocarbons (PAHs) after 60 120 days. The results this study exhibited a clear difference diversity between non-rhizosphere samples rhizospheres In both rhizospheres, an incremental change PAHs degrading genera observed 120th day compared 60th ones. Among genera,...
Bioaugmentation effectively enhances microbial bioremediation of hazardous polycyclic aromatic hydrocarbons (PAHs) from contaminated environments. While screening for pyrene-degrading bacteria a former manufactured gas plant soil (MGPS), the mixed enrichment culture was found to be more efficient in PAHs biodegradation than culturable pure strains. Interestingly, analysis 16S rRNA sequences revealed that dominated by previously uncultured member family Rhizobiaceae. The utilized C1 and other...
Perfluorobutane sulfonate (PFBS), due to its increasing use as an alternative perfluooctane (PFOS), is widely detected in humans and the environment, necessitating evaluation of potential ecotoxicological risk. We assessed toxicity bioaccumulation PFBS Caenorhabditis elegans, using lethality, locomotion, reproduction, life span, growth, chemotactic behavior effect parameters. In addition, a total 6 generations exposed parent animals were monitored for brood, span behaviors. Life brood size...
A Gram-positive bacterium, Microbacterium esteraromaticum MM1 able to degrade organophosphorus pesticides such as fenamiphos and malathion, also possessed the ability high molecular weight polycyclic aromatic hydrocarbon (PAH), pyrene (Pyr) benzo[a]pyrene (BaP). The strain degraded 98.7% of initially spiked 100 mg L−1 within 15 days from M9 mineral salts medium (pH 7.0) with 0.1% glucose. At optimal pH 7.0, 57.81% (100 L−1) was sole carbon source. In order determine influence sources...
Abstract Per‐ and polyfluoroalkyl substances (PFAS) have emerged as contaminants of global concern. Among several PFAS, perfluorooctanoic acid (PFOA) perfluorooctane sulfonate (PFOS) are persistent bioaccumulative compounds. We investigated the cyto‐genotoxic potential PFOS to Allium cepa root meristem cells. The A. tips were exposed 6 different concentrations (1–100 mg L −1 ) for 48 h. Reduction in mitotic index chromosomal aberrations was measured genotoxic endpoints meristematic Exposure...
