Abstract The potentially harmful effects of consuming toxic elements (PTEs) and microplastics (MPs) regularly via drinking water are a significant cause for worry. This study investigated PTEs (Cd, Cu, Cr, Ni, Pd, Zn, Co), MPs, turbidity, pH, conductivity, health risk assessment in the treatment plant Kielce, Poland. Zn had highest concentrations throughout facility, whereas Cd, Pb, Co lower (< 0.1 µg/L). order among specified was like Zn˃Cu˃Ni˃Cr˃Cd˃Pb Co. minimum turbidity 0.34, maximum 1.9 NTU. range pH samples 6.51—7.47. conductivity 1,203—1,445 ms samples. These identified MPs were categorized into fiber fragments. color these blue, red, black, green, transparent. size 196 4,018 µm, while average 2,751 ± 1,905 µm. concentration per liter 108.88 55.61. listed C, O, Na, Mg, Al, Si, K, Ca, Ti. Fe predominant seen using EDX. HQ values less than one adults children. human associated with all detected revealed that exhibit satisfactory degree non-carcinogenic adverse risk. HI children age groups one. In most samples, carcinogenic value exceeds threshold 10 −6 . MP should be periodically monitored to minimize consumers' environmental pollution risks.

Microplastics (MPs), measuring less than 5 mm, have been causing environmental concerns in aquatic ecosystems, and work has done indoor environments, where humans spend most of their lives. This finding revealed a diverse range MPs within house dust samples. These encompassed fibres, fragments, foams, pellets films. Due to the ubiquity textile-based items, fibres are common MP. The different colours like black, red, blue, yellow, white brown. study there were substantial differences MP sizes across households. average size was 178.87–3713.99 µm. One hundred eighteen particles identified as MPs. 22 types MPs, shedding light on these materials’ extensive sources applications everyday household items. environments raise about potential human exposure underscore need for further research into health implications. found samples low-density polyethylene, polypropylene, polyamide, polyvinyl chloride, high-density polyethylene polystyrene.

Abstract This review explores the hidden hazards associated with reuse of treated wastewater and sewage sludge in agriculture while proposing mitigation strategies. It examines origins pathways microplastics (MPs) treatment plants how these pollutants infiltrate agricultural ecosystems. The assesses effectiveness MP removal from its fate soil after reuse, highlighting contamination dynamics need for proactive measures. Introducing remediation methods is crucial addressing this issue. Alarming evidence MPs human blood, testis, semen, placenta underscores urgency solutions, revealing significant threats to health, particularly reproductive health. advocates sustainable practices effective strategies mitigate contamination, promoting environmental preservation, food safety, health protection.

This paper investigates the transmission characteristics of cough droplets from infected individuals in office environments under influence an impinging jet ventilation (IJV) system based on Eulerian–Lagrangian model. The accuracy dispersed phase model and IJV simulation was validated by analyzing a single droplet evaporation model, publicly available experimental results, previously simulated results. effects different exhaust locations, relative positioning to individual, application partitions spatial propagation are explored. results indicate that exhibit significant ability obstruct capture droplets. Under static conditions, they capable capturing over 36% generated coughing, although this efficiency may be slightly influenced system. notably affects movement, with progressively converging toward upper-left corner room as airflow develops. exhausts, combination system, is crucial impeding removing Taking into account variations individual's position, centrally located arrangement might provide more effective inhibition virus dispersion.

Abstract Micro and nanoplastics (MNPs) may enter the human body through food, drink, air. Scientists have mainly focused on first two routes, but little is known about third. A cascade impactor having a size range of (> 2.5, 1.0–2.5, 0.50–1.0, 0.25–0.50, < 0.25 μm) was used to study segregation MNPs in different indoor commercial markets. The morphological characterization showed presence fibers, fragments, films, lines, foam, pellets with colors. Three hundred-seven particles were scanned for chemical description under Micro-Raman analysis, 247 identified categorized into 52 . standard found samples PTFE, PE, PP, HDPE, PA, LDPE, PAM. SEM-EDX analysis that C, O, F had highest weight% among all elements seen, while F, Mg, Al common elements. These are small enough get inhaled easily. these environments vast sources emit polymeric harmful health impacts, particularly employees working there. So, there need take necessary measures minimize release their impacts health.

The aging of micro- and nanoplastics (MNPs) significantly affects their environmental behavior ecological impacts in both aquatic terrestrial ecosystems. This review explored the known effects on MNPs identified several key perspectives. Firstly, can alter fate transport due to changes surface properties. alteration accelerates accumulation specific habitats like oceans soils, resulting increased bioaccumulation by organisms. In addition, aged interact differently with living organisms than pristine counterparts influencing attachment biofilms other microorganisms Moreover, processes exhibit adverse via increasing bioavailability potential toxicity as degradation products are released. Last but not least, biodegradation be altered process, thus affecting rates pathways environment. However, there still knowledge gaps regarding natural behaviors MNPs, such mechanisms different types plastic, influence factors, release pollutants, even transformation Therefore, a great contribution made sustainable plastic use preservation studying common subsequent biological effects.
