Antioxidants have been received recognized as contaminants in the environmental field due to the reports of adverse effects. In this study, a total of 35 outdoor dusts and 20 educational indoor dusts were sampled to investigated the occurrence and spatial distribution of antioxidants, and eight antioxidants were positively found in dusts. For the indoor dusts, the total antioxidant concentrations (Σ 8 Ant) were in the range of 15.7–5282 ng/g, 2,6-di-tert-butyl-4-methylphenol (BHT) was the dominate compound which constituted of 46.4% in the total concentrations of detected antioxidants. The composition profiles of antioxidants (67.9%) in outdoor dusts were different from that in indoor dusts, N -(1,3-dimethylbutyl)- N ′-phenyl-p-phenylenediamine (6PPD) was the main component of all the identified antioxidants. Various microenvironments exhibited different contamination characteristics of antioxidants, the rank order of Σ 8 Ant was following as: campus roads (average concentration: 35.4 ng/g) < pedestrian streets (59.1 ng/g) < urban roads (92.9 ng/g) < teaching buildings (105 ng/g) < laboratory buildings (530 ng/g) < dormitories (1652 ng/g). Based on the measured Σ 8 Ant in dusts, we estimated daily intake via dust ingestion to be 3.90e −2 to 9.55e −2 ng/kg BW/day for adults under high exposure scenario. Overall, the occurrence and spatial distribution of antioxidants in outdoor and educational indoor spaces were investigated and the potential risks of detected antioxidants exposure in toddlers and adults were assessed in the present study.

Beta-cypermethrin (beta-CP), an important pyrethroid insecticide, and its main acid metabolites are frequently detected in human samples. Because beta-CP may pose some risk to human health, we studied dynamics and residues of beta-CP and its metabolites in hen egg, droppings, blood, and 15 other tissues after continuous exposure. A digestive model was then used to study beta-CP’s digestive fate. Beta-CP and its metabolites significantly accumulated in tissues with high lipid contents and were readily transferred to eggs. Beta-CP was mainly metabolized into acid metabolites that accumulated in egg and edible tissues of laying hens, suggesting that humans may be exposed to beta-CP acid metabolites through food.

There is an increasing demand for epidermal sensors that can adapt to the contours and the movements of the human body, but the fabrication of prevalent polymer-based epidermal sensors often involves costly materials and complex procedures. Paper has emerged as a cost-effective substrate for next-generation epidermal sensors, featuring such advantages as bendability, breathability, biocompatibility, and environment-friendliness. However, transducing materials are commonly introduced to paper substrates in post hoc manners or through time-consuming syntheses, in addition to the direct manufacturing of paper. Here we report an integrative method to fabricate epidermal paper-based graphene sensors, where graphene induction and paper cutting can be achieved in a single lasing procedure to generate both transducing components and overall sensor formats. Lasing conditions are systematically explored, mainly to control the multifaceted properties of the obtained graphene transducers. The resultant paper-based graphene structures exhibit sufficient reliability in various scenarios regarding storage, lighting, and deformation. Paper-based graphene sensors are strategically designed in terms of overall formats, geometric patterns, hydrophilicity/hydrophobicity, surface functionalization, and readouts for measuring biophysical and biochemical information relevant to human health. The sensor performance can be optimized by adjusting laser power, and the calibrated sensitivities for mechanical strain, temperature, humidity, pH, and glucose are 76.93, –0.15% °C –1 , 37.06 μA % –1 , 28.13 mV pH –1 , and 1.26 μA mM –1 , respectively. Multimodal health monitoring is demonstrated with paper-based graphene sensors. Our approach can facilitate the generation of epidermal paper-based sensors and meet diverse requirements of health monitoring.

The excessive content of heavy metal ions in water has attracted increasing worldwide attention due to the potential harm to human health and ecological systems. Therefore, it is particularly significant to research and develop a sensitive and straightforward water quality monitoring method. Here, a dual-network designed hydrogel poly(acrylic acid-co-N-methylolacrylamide)/poly(3,4-ethylenedioxythiophene): polystyrenesulfonate, P(AA-co-N-MA)/PEDOT: PSS, was constructed and used for Fe3+ detection. Compared with previous reports, the P(AA-co-N-MA)/PEDOT: PSS hydrogel has a much more sensitive and convenient detection of immune iron ions (Fe3+), is applied to monitor a trace of over-the-standard (the lower limit of detection is 0.52 ppm corresponding to 0.06 S/m for human health monitor, and the threshold for water quality monitoring is 0.16 S/m). The relationship between Fe3+ content and the conductivity of the hydrogel allows it to integrate with other electron devices to provide an early warning function for Fe3+ in the human body, which would be of great significance to human health monitoring.

Microplastics (MPs) can enter the reproductive system and can be potentially harmful to human reproductive health . In this study, 13 types of microplastics (MPs) were identified in patient blood, cancer samples, and paracarcinoma samples using Raman spectroscopy , with polyethylene, polypropylene and polyethylene-co-polypropylene being the most abundant polymer types. Futher, cotton was also found in our study. The diversity and abundance of MPs were higher in blood samples than in cancerous tissues, and there was a significant positive correlation between diversity (p < 0.05). Furthermore, the diversity and abundance of MPs in cancerous tissues were higher than in paracancerous tissues. The dimensional sizes of MPs in these samples were also very similar, with the majority of detected MPs being smaller in size. Correlation analysis showed that patient’s age correlated with the abundance of MPs in blood samples, body mass index (BMI) correlated with the abundance of MPs in cancerous tissues. Notably, the frequency with which patients consume bottled water and beverages may also increase the abundance of MPs. This study identifies for the first time the presence of MPs and cotton in cancerous and paracancerous tissues of human cervical cancer patients. This provides new ideas and basic data to study the risk relationship between MP exposure and human health.

The advancement of pressure sensors featuring high sensitivity, wide detection ranges, and linear response characteristics is important for advancing tactile sensing technologies for robots and human health monitoring. However, conventional preparation suffers from nonlinear signal output, non-environmental friendliness, and poor comfort, which affects the sensor’s ability to accurately detect different pressure levels, which is critical for subtle haptic feedback systems. To overcome these challenges, our research introduces a breakthrough in flexible capacitive pressure sensors by ingeniously integrating thermal stress-induced microstructured ionic gels with textile electrodes within a band-aid-like form factor. This method prevents the requirement for external templates or intricate manufacturing procedures, streamlining the production process while enhancing the sensor’s performance. The pivotal role of the ionic gel lies in its ability to form an efficient electric double layer (EDL), which adeptly transforms ion–electron interface interactions into measurable pressure-sensing outputs. Notably, this band-aid-based iontronic sensor showcases exceptional performance metrics. It exhibits an extraordinarily high sensitivity, reaching 5652.41 kPa −1 , and demonstrates a broad pressure detection range (from 0-400 kPa). Additionally, the sensor responds rapidly to pressure changes, maintains robust long-term cycle stability, and boasts an impressively low detection threshold. Its potential applications, particularly in the precise monitoring of human muscle movements, open exciting new avenues for both health monitoring and the broader field of flexible electronic devices. This showcases the potential of everyday materials in advanced technological applications.

MXene-composited conductive hydrogels have received extensive attention in flexible, portable and self-powered wearable electronics based on triboelectric nanogenerators (TENGs). Yet, the incompatibility of the MXene with hydrogel matrix due to easy oxidation and weak interactions with polymer chains weakens the performance of hydrogels. Herein, inspired by the structure of leaves, tannic acid (TA) with abundant catechol groups was introduced to encapsulate MXene and TEMPO-oxidized cellulose nanofibers (TOCNF) was intercalated to support the MXene nanosheets as leaf vein, forming a stable TOCNF/TA@MXene nano-motif with three-dimensional (3D) network. Benefiting from the addition of TOCNF, TOCNF/TA@MXene exhibited long-term stability (>10 days) in aqueous environment with the presence of oxidant. Therefore, the obtained TOCNF/TA@MXene-composited hydrogel (PCM) exhibited high stretchability (>800 %), reliable fatigue resistance and good adhesiveness, which can be served as electrodes of flexible TENGs. The formed PCM-TENG demonstrated flexibility and versatility, achieving an open-circuit voltage of 106 V, a short-circuit current of ~2 μA and a transfer charge of ~31 nC even in a single-electrode mode. Besides, PCM-TENG showed enduring practicality and responsiveness as a self-powered sensor to detect human biomotions. PCM-TENG also presented desirable photothermal antibacterial capacity and cytocompatibility. All these properties endowed the PCM-TENG with great application potential in human healthcare.

Recently, cellulose paper based triboelectric nanogenerators (CPTENGs) has gained widely attention due to the development of wearable, green and miniaturized electronic products. Modification of cellulose fibers or paper is a feasible method to improve the output performance of CPTENGs, however, the simple and effective routes to improve the triboelectric property of cellulose paper still remain a challenge. Herein, we report a simple method to prepare PEO/cellulose composite paper (PEO/CCP) via mixing polyethylene oxide (PEO) with cationic cellulose fibers. Benefiting from amino groups and PEO, the composite paper exhibits higher triboelectric positive property and triboelectric charge density, thereby endowing PEO/CCP based TENG with outstanding output performance. The voltage, current and power density peak values of PEO/CCP based TENG exhibited linear relationship with amino groups content; in this instance, the performance of the TENGs can be readily adjusted by the amino groups. The voltage, current and power density of PEO/CCP based TENG can be up to 222.1 V, 4.3 μA, and 217.3 mW•m −2 , respectively. Moreover, a human-health detection device based on this TENG can monitor the physiological signals such as eye muscles, respiration, heart beat and wrist pulse, promising potentials for applications in human health-care.

Background As a common industrial raw material and chemical intermediate, p-Aminophenol (pAP) is recognized as a serious pollutant that poses harm to both the environment and human health. The traditional detection methods for pAP have the advantages of good selectivity and high sensitivity, but their complex operation and time-consuming defects limit their application in on-site detection. Therefore, it is necessary to develop a simple, low-cost, rapid and high-sensitivity method for the detection of pAP. Results Noble metal nanoparticles have been widely used in colorimetric sensing because of their simplicity and practicality. Herein, we presented a simple, excellent sensitive and selective colorimetric method for high-performance detection of pAP based on Cu–Au nanoparticles (Cu–Au NPs) and KIO 3 . In the presence of pAP, KIO 3 was reduced to I 2 , which subsequently chemically adsorbed onto Cu–Au NPs surface and induced the dispersion and reorganization of Cu–Au NPs, along with prominent color change of the dispersion from gray-blue to pink and the transformation of Cu–Au NPs from chain-like aggregates to individual dispersed, irregular, subspherical nanoparticles. The mechanism was verified by TEM , DLS , Zeta potential , UV–vis and XPS . Meanwhile, Cu–Au NPs probe can rapidly detect pAP within 25 min, the limit of detection of pAP probe is 5 μM by the naked eyes and 0.03 μM by UV–vis absorption spectrum . Significance and novelty This is the first colorimetric assay for pAP based on Cu–Au NPs probe. The satisfactory linearity (R 2 = 0.9984) indicates that the colorimetric probe based on Cu–Au NPs and KIO 3 can be utilized for quantitative detection of pAP. The detection results of pAP in real environmental water samples, urine samples and paracetamol tables demonstrate the practicability of pAP colorimetric probe.

Heavy metals (HMs) pose a significant threat to soil quality, plant growth, and human health. However, the impacts (transport, pollution, and health risk) of HMs in medicinal and edible plants with rich value growing in high background soil for a long time remain unclear. So the effects of HMs on the “soil-medicinal and edible plant-human” system were comprehensively studied. Houttuynia cordata Thunb. (HCT) and growing soil were collected from the farmland around Beiya mining area located in Three Parallel Rivers of Yunnan Protected Areas, China. The transport, pollution, and health risks of HMs in the system were investigated by determining the content of active ingredients, HMs, and physicochemical properties in HCT and soil. The results of comprehensive analysis using various measurement and analysis methods showed that Zn, Cu, Mn, and Co in soil could affect the contents of available nutrients (available P (AP), available K (AK), and organic matter (OM)), while AP, OM, pH, Co, and Fe in soil were closely related to the formation of HCT quality. Cr and Fe had the strongest transport capacity in stems and leaves of HCT, respectively. Furthermore, it is worth noting that Cr, Pb, and Cu had caused serious pollution to HCT in the area. Pb and Cu are tolerable levels for human health and may pose a carcinogenic risk. Our study demonstrates that HCT is expected to be a marker of heavy metal pollution in the area and provides a scientific basis for making effective regulations on HMs control and scientific planting.

Hydrogels with integrated attributes of stretchability, conductivity, transparency and robustness have been emerging because of their promising applications in wearable devices , human health monitoring, advanced intelligent systems and energy harvesting . In this paper, we developed stretchable and conductive hydrogels via hybrid double networks approach by combination of rigid physically cross-linked gelatin, tough chemically cross-linked polyacrylamide (PAM) and poly(3,4-ethylene dioxythiophene): poly(styrene sulfonate) (PEDOT: PSS) as conducting component. The double networks can be further interlocked by using physical entanglements and abundant dynamic hydrogen bonds , contributing to the improved mechanical properties and self-recovery ability. A transparent and wearable strain sensor is fabricated by sandwiching the hydrogels with two layers of adhesive polyurethane (PU) tape, exhibiting good sensitivity (gauge factor (GF) = 1.58), ultra-wide sensing range of 0-2850% strain, short response time of 200 ms and superior durability and reproducibility (1200 cycles), which endows the sensitive monitors with effective discernibility for detecting intricate human motions. Importantly, the hydrogel-based device can act as a highly stretchable (300% strain) triboelectric nanogenerator (STENG) for efficient energy harvesting, giving a short circuit current (I SC ) of 26.9 μA, open circuit voltage (V OC ) of 383.8 V and short-circuit transferred charge (Q SC ) of 92 nC. The integrated abilities of strain sensing and energy harvesting promise the hydrogels for high performance self-powered wearable devices and stretchable power sources.

During the COVID-19 pandemic, excessive amounts of disinfectants and their transformation products entered sewer systems worldwide, which was an extremely rare occurrence before. The stress of residual chlorine and disinfection by-products is not only likely to promote the spread of antibiotic resistance genes (ARGs), but also leads to the enrichment of chlorine-resistant bacteria that may also be resistant to antibiotics. Therefore, the potential impact of such discharge on ARG composition should be studied and the health risks should be assessed. Thus, this study combined high-throughput 16S rRNA gene amplicon sequencing and metagenomic analysis with long-term batch tests that involved two stages of stress and recovery to comprehensively evaluate the impact of residual chlorine on the microbial community and ARG compositions in sewer systems. The tests demonstrated that the disturbance of the microbial community structure by residual chlorine was reversible, but the change in ARG composition was persistent. This study found that vertical propagation and horizontal gene transfer jointly drove ARG composition succession in the biofilm, while the driving force was mainly horizontal gene transfer in the sediment. In this process, the biocide resistance gene (BRG) subtype chtR played an important role in promoting co-selection with ARGs through plasmids and integrative and conjugative elements. Moreover, it was further shown that the addition of sodium hypochlorite increased the risk of ARGs to human health, even after discontinuation of dosing, signifying that the impact was persistent. In general, this study strengthens the co-selection theory of ARGs and BRGs, and calls for improved disinfection strategies and more environmentally friendly disinfectants.
