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.

Aged micro(nano)plastics (MNPs) are normally the ultimate state of plastics in environment after aging. The changes physical and chemical characteristics aged MNPs significantly influence their environmental behavior by releasing additives, forming byproducts, adsorbing contaminants. However, a systematic review is lacking on effects ecological human health regarding increasing but scattered studies results. This Review first summarizes unique methods for quantifying aging degree. Then we focused potential impacts organisms, ecosystems, health, including "Trojan horse" under real conditions. Through combining meta-analysis analytic hierarchy process (AHP) model, demonstrated that, compared to virgin MNPs, would result biomass decrease oxidative stress increase organisms lead total N/P greenhouse gas emissions ecosystems while causing cell apoptosis, antioxidant system reaction, inflammation health. Within framework risk assessment, used quotient (RQ) physiologically based pharmacokinetic (PBK) models as examples illustrate importance considering degree data acquisition, model building, formula evaluation. Given risks our urgent call more understand hazards real-world environments.

The smaller size fraction of plastics may be more substantially existing and detrimental than larger-sized particles. However, reports on nanoplastics (NPs), especially their airborne occurrences potential health hazards to the respiratory system, are scarce. Previous studies limit understanding real effects, since sphere-type polystyrene (PS) nanoparticles differ from NPs occurring in nature with respect physicochemical properties. Here, we employ a mechanical breakdown method, producing directly bulk plastic, preserving NP properties nature. We report that among four relatively high abundance materials PS, polyethylene terephthalate (PET), polyvinyl chloride (PVC), (PE) 100 nm, PVC induced slightly severe lung toxicity profiles compared other plastics. cytotoxicity is higher commercial PS comparable natural particles silicon dioxide (SiO2) anatase titanium (TiO2). Mechanistically, BH3-interacting domain death agonist (Bid) transactivation-mediated mitochondrial dysfunction nuclear receptor coactivator 4 (NCOA4)-mediated ferritinophagy or ferroptosis likely common mechanisms regardless chemical composition. This study provides comprehensive data for evaluating risk atmospheric health.

In vitro cell-transforming potential of secondary polyethylene terephthalate and polylactic acid nanoplastics

Journal of Hazardous Materials, Год журнала: 2024, Номер 469, С. 134030 - 134030

Continuous exposure to plastic pollutants may have serious consequences on human health. However, most toxicity assessments focus non-environmentally relevant particles and rarely investigate long-term effects such as cancer induction. The present study assessed the carcinogenic potential of two secondary nanoplastics: polyethylene terephthalate (PET) generated from bottles, a biodegradable polylactic acid material, respective examples environmentally existing new bioplastics. Pristine polystyrene nanoplastics were also included for comparison. A broad concentration range (6.25 – 200 μg/mL) each nanoplastic was tested in both initiation promotion conditions regulatory assessment-accepted vitro Bhas 42 cell transformation assay. Parallel cultures allowed confirmation efficient cellular internalisation three nanoplastics. Cell growth enhanced by assay, PET conditions. Moreover, number transformed foci significantly increased only highest which showed dose-dependency, indicating that nano can act non-genotoxic tumour promotor. Together, these findings support risk assessment raise concerns regarding whether real-life co-exposure other environmental result synergistic capacities. Secondary (NPLs) waste degradation bioaccumulate tissues cause cancer. Currently, information NPL carcinogenicity remains scarce. By using we first time NPLs, bioplastic, widely spread petroleum-based alternative, respectively. Notably, accelerated bioplastics has been associated with an release NPLs into environment. data will serve plastics.

The increasing presence of secondary micro/nanoplastics (MNPLs) in the environment requires knowing if they represent a real health concern. To such end, an important point is to test representative MNPLs as denominated true-to-life MNPLs, resulting from degradation plastic goods lab conditions. In this study, we have used polyethylene terephthalate (PET) NPLs PET water bottles. Since inhalation exposure route environmental MNPLS, mouse alveolar macrophages (MH-S) target cell, and study focused only on cells that internalized them. This type approach novel it may capture realistic adverse effects PETNPLs cells, thereby mitigating any biases while assessing risk these MNPLs. Furthermore, utilized set biomarkers including intracellular reactive oxygen species (ROS) levels, variations mitochondrial membrane potential values, macrophage polarization M1 (pro-inflammatory response) M2 (anti-proinflammatory possible cellular due PETNPLs.
