“…Increasing human activities have threatened services and goods provided by coastal marine ecosystems, due to increases in surface runoff, riverine discharge, and industrial and domestic wastewater discharges. Consequently, coastal oceans are recognized as important sinks of various materials such as organic carbon, heavy metals, nutrients, and persistent organic pollutants (POPs), among others [Leithold et al, 2016;Gao et al, 2014;Xing et al, 2017;Mwangi et al, 2016]. In recent years, the focus on POPs, especially polycyclic aromatic hydrocarbons (PAHs), in coastal marine ecosystems has increased, due to their adverse effects on marine organisms.…”

This study conducted the first extensive and comprehensive investigation of the regional‐scale sedimentary polycyclic aromatic hydrocarbons (PAHs) concentration, flux, and budget in the continental shelves of the Eastern China Marginal Seas (ECMSs). Surface sediment samples from multiple sites were collected and assessed, and the latest data from current research were assessed. The spatial distribution pattern of PAHs in the ECMSs was significantly influenced by the regional hydrodynamics, sediment properties (grain‐size, total organic carbon [TOC] content, and sedimentation rate), and anthropogenic impacts. Relatively higher PAHs concentrations occurred in areas with fine‐grained sediment. Results of source apportionment found that the relative proportions of PAHs showed significant regional variation, mainly influenced by socioeconomic differences between north and south China. The PAHs burial flux in the study area ranged from 11.2 to 1308 ng cm−2 yr−1 with an average value of 101 ± 104 ng cm−2 yr−1. The area‐integrated sedimentary PAHs burial flux across the ECMSs was 494 t yr−1. A mass budget calculation revealed that riverine input and atmospheric deposition were the most significant sources contributing, 28.4% and 71.6%, respectively. The study demonstrated that net PAHs transportation occurs between the Bohai Sea (BS) and Yellow Sea (YS), with a flux of approximately 10.2 t yr−1. PAHs were also transported from YS to the East China Sea (ECS), due to water exchange between the YS and ECS. Additionally, substantial amounts of PAHs in the inner shelf of the ECS were transported out of the shelf area due to cross‐shelf plume.

“…The anthropogenic emission of NH 3 was mainly derived from fertilizer use, livestock manure, vehicle exhausts, and industrial processes . Of these, livestock manure and synthetic fertilizer application were considered the two major sources of NH 3 emissions, accounting for 80 %-90 % of total emissions Xu et al, 2016). Nitrogen fertilizer consumption has decreased since 2013 (http://www.stats.gov.cn/, last access: 1 January 2013), which was in good agreement with the variation in the NH + 4 concentration in the precipitation.…”

Abstract. The acid deposition has been considered to be a severe environmental issue in China. The pH, electrical conductivity (EC), and concentrations of water soluble ions (NO3-, Cl−, Ca2+, K+, F−, NH4+, Mg2+, SO42-, and Na+) in the precipitation samples collected from 320 cities during 2011–2016 across China were measured. The mean concentrations of F−, NO3-, and SO42- were in the order of winter (6.10, 19.44, and 45.74 µeq L−1) > spring (3.45, 13.83, and 42.61 µeq L−1) > autumn (2.67, 9.73, and 28.85 µeq L−1) > summer (2.04, 7.66, and 19.26 µeq L−1). Secondary ions (SO42-, NO3-, and NH4+) and F− peaked in the Yangtze River Delta (YRD) and Sichuan basin (SB). Crustal ions (i.e. Ca2+, Mg2+), Na+, and Cl− showed the highest concentrations in the semi-arid regions and the coastal cities. The statistical methods confirmed that the mean anthropogenic contribution ratios to SO42-, F−, NO3-, and NH4+ at a national scale were 46.12 %, 71.02 %, 79.10 %, and 82.40 %, respectively. However, Mg2+ (70.51 %), K+ (77.44 %), and Ca2+ (82.17 %) mostly originated from the crustal source. Both Na+ (70.54 %) and Cl− (60.42 %) were closely linked to sea salt aerosols. On the basis of the stepwise regression (SR) analysis, it was proposed that most of the secondary ions and F− were closely related to gross industrial production (GIP), total energy consumption (TEC), vehicle ownership, and N fertilizer use, but the crustal ions (Ca2+ and K+) were mainly controlled by the dust events. The influence of dust days, air temperature, and wind speed on ions increased from southeast China (SEC) to central China, and then to northwest China (NWC), whereas the influence of socioeconomic factors on acid ions (SO42- and NO3-) displayed the higher value in east China.

“…The remote transmission of pollutants in this study was primarily impacted by the air mass coming from the northwest (Figure 4). The distribution of organic pollutants in environments is affected by various factors such as NH 4 -N, NO 3 -N, PO 4 -P, SiO 3 -Si and TOC [26]. To understand the relationship between environmental factors and the concentration of PhACs in snow, we analyzed the correlation.…”

“…As shown in Table S4, 14 kinds of PhACs (chlormadinone acetate, trenbolone, indomethacin, sulfamerazine, desacetylcefotaxime, sulfamonomethoxine, nitrazepam, tilmicosin, prednisone, Generally, NH 4 -N mainly comes from agricultural activities [52,53], including volatilization of nitrogen fertilizer, animal husbandry, application of human and animal excreta, and other organic fertilizers [54,55], and the relatively high content of NH 4 -N in snow is associated with the well-developed production of agriculture and animal husbandry near JZB [26]. NO 3 -N is considered to be closely associated with industrial and traffic emissions [56,57], and NO 3 -N in snow is mainly in connection with well-developed local traffic and coal-fired heating in winter.…”

The occurrence and distribution of 110 pharmaceutically active compounds (PhACs) were investigated in snow near Jiaozhou Bay (JZB), North China. All target substances were analyzed using solid phase extraction followed by liquid chromatography coupled to tandem mass spectrometry.A total of 38 compounds were detected for the first time in snow, including 23 antibiotics, eight hormones, three nonsteroidal anti-inflammatory drugs, two antipsychotics, one beta-adrenergic receptor and one hypoglycemic drug. The total concentration of PhACs in snow ranged from 52.80 ng/L to 1616.02 ng/L. The compounds found at the highest mean concentrations included tetracycline (125.81 ng/L), desacetylcefotaxime (17.73 ng/L), ronidazole (8.79 ng/L) and triamcinolone diacetate (2.84 ng/L). The contribution of PhACs in the vicinity of JZB to the PhACs in the snow is far greater than the contribution of those transmitted over a long distance. PhACs are mainly derived from drugs applied to local humans and animals. Based on the individual risk quotient (RQ) values, tetracycline poses high risks to the relevant aquatic organisms (algae and invertebrates). The rational application and scientific management of PhACs is an effective approach to reduce the ecological risks in JZB.
