... After entering the environment, these plastic fragments undergo aging processes such as UV radiation, mechanical fragmentation, and biodegradation, ultimately decomposing into smaller microplastics (MPs,<5 mm) or nanoplastics (NPs,<1 µm) [2]. Micro/nanoplastics (MNPs) often have a larger specific surface area, rougher surfaces, and increased hydrophilicity, which results in enhanced migration ability in the medium [26,29,57]. MNPs can act as carriers of toxic substances (persistent organic pollutants, heavy metals, drugs, etc.) in environmental media, promoting the transport of pollutants [55,59,65].MNPs exhibit a Trojan horse effect, promoting the transportation of pollutants and increasing the ecological risks caused by compound pollution [45,65]. ...

... The low WEOM concentration in Lake Baiyangdian (0.47-5.62 g/kg, 1.61%-9.35%) may be related to the abundance of microorganisms in the water and in the shoreline soil ( Yuan et al., 2014 ;Wang et al., 2022b ;Zhang et al., 2023a ). This change may be caused by the annual water transfer projects implemented in Lake Baiyangdian, which further accelerate the growth and reproduction of microorganisms. ...

... The fuel type and property could significantly influence the emission characteristics of air pollutants Huang et al., 2016;Yang et al., 2019;Lu et al., 2021;Amaral et al., 2021). The timeline of the vehicle-used gasoline/CNG standards and national emission standards for light-duty passenger vehicles (LDPVs) in China were listed in the Table S1. ...

... The profiles of particulate elements generated from experimental investigation are required for development of in-depth emission inventories of size-resolved particulate elements, and such specific data can be used for air quality modeling and assessment of various scenarios of human health impacts due to atmospheric exposure. The trends and size distribution in profiles of particulate elements emitted from such diesel engine exhausts depend on the extent of incomplete combustion process, quantity of burned lubricating oil, chemical composition of fuel oil and mechanism of agglomeration that combines finer particles with partly burned fuel present in the exhaust stream (Hao et al., 2019;Grigoriadis et al., 2021). Among various sizes of PM, ultrafine particles (PM 0.1 : AED ≤ 0.1 µm), submicron particles (PM 1 : AED ≤ 1.0 µm) and fine particles (AED ≤ 2.5 µm) generated from these diesel engine exhausts have different aspects in terms of depositions in three distinct regions (head airways (HA), trachea and bronchial (TB), and pulmonary alveolar (PA)) of the human respiratory tract (Lloyd and Cackette, 2001;Tsai et al., 2015;Dong et al., 2019;Qiu et al., 2022). ...

... However, the majority of waste-water treatment plants cannot reduce the residual OTC in waste water for the lack of efficient processes at present. In general, the methods to remove the antibiotics are adsorption [17,18], strong oxidation [19], photodegradation [20], electrochemical treatments [21], membrane filtration [22] and biodegradation. Adsorption can effectively remove OTC with a low concentration in water, and it has been known that OTC can be absorbed by different minerals [23,24], synthetic materials [25][26][27][28], and so on. ...

... Nevertheless, a significant challenge arises because most surface runoffs are frequently contaminated and fall short of established water quality standards (Wang et al. 2016). Characteristically, surface runoff in various parts of the world, including China, often exceeds the class five standard for surface water quality in China by a factor of about four (Huang et al. 2007). ...

... Temperature is another factor that influences ammonium nitrogen adsorption [63]. The humic acid colloid also influences the adsorption of DDT in sediments [59,64]. ...

... Similarly, physical decontamination approaches e.g. thermal (Araújo et al., 2016;Minghui et al., 1996) and sorption on various matrices (Enriquez-Victorero et al., 2014;Hua et al., 2017;Pandey et al., 1999;Sawicki and Mercier, 2006;Silvani et al., 2019;Sprynskyy et al., 2008;Wadaskar et al., 2006;Yang et al., 2013) (most often activated carbon) are not considered here. ...

... Physicalchemical treatment and biological treatment are mainly used to treat highly concentrated organic wastewater. The principle of physical-chemical treatment, including catalytic oxidation [4], incineration [5], solvent extraction [6], chemical flocculation [7][8], and the electro-chemical method [9]. However, the physical-chemical method is not only costly, but difficult to treat. ...

... The PALM-4U model, which was publically released on October 31, 2018, is able to simulate atmospheric processes (both physics and chemistry) for entire cities not only for neutral atmospheric conditions but also for non-neutrally stratified atmospheres. This is particularly important since atmospheric stability strongly varies within cities over short distances, depending on topography, land use, season, and time of day (Nordbo et al., 2013), and has strong effects on flows and dispersion of heat (Ramamurthy et al., 2007), water vapour and air pollutants (Gao et al., 2016;Yassin, 2013), particularly near the ground. ...
