This study aimed to update information on the presence and persistence of antibiotics in wastewater from four typical pharmaceutical plants in China and the removal of antibiotics by the wastewater treatment process. It also evaluated the environmental impact of antibiotic residues through wastewater discharge into receiving water bodies. The results indicated that 13 antibiotics were detected in wastewater samples with concentrations ranging from 57.03 to 726.79 ng/L. Fluoroquinolones (FQs) and macrolides (MLs) were the most abundant antibiotic classes in wastewater samples, accounting for 42.5% and 38.7% of total antibiotic concentrations, respectively, followed by sulfonamides (SAs) (16.4%) and tetracyclines (TCs) (2.4%). Erythromycin-H2O (ERY), lincomycin (LIN), ofloxacin (OFL), and trimethoprim (TMP) were the most frequently detected antibiotics; among these antibiotics, the concentration of OFL was the highest in most wastewater samples. No significant difference was found in the removal of antibiotics between different treatment processes, and more than 50% of antibiotics were not completely removed with a removal efficiency of less than 70%. The concentration of detected antibiotics in the receiving water was an order of magnitude lower than that in the wastewater due to dilution. Finally, an environmental risk analysis showed that lincomycin and ofloxacin could pose a high risk at the concentrations detected in effluents and a medium risk in their receiving waters, highlighting that they were a potential hazard to the health of the aquatic ecosystem.

“…Per- and polyfluoroalkyl substances (PFAS) [previously called perfluorochemicals (PFCs)] are a group of thousands of man-made chemicals that are now ubiquitously found in the environment and in living organisms. − PFAS have been manufactured for over 70 years due to their useful characteristics that include the ability to repel dirt and water, act as a surfactant, and resist high temperatures . Products containing PFAS include carpets, furniture, corrosion resistant pipes, nonstick cookware, food packaging, firefighting foam, and microwaveable food containers. , PFAS have been identified as persistent organic pollutants (POPs) or “forever chemicals” and continue to be found in the environment and animals across the globe, even in the Arctic and Antarctic regions, due to the decades of large-scale manufacturing and uncontrolled pollution in the environment. − …”

“…Due to concerns of bioaccumulation and toxicity, the U.S. Environmental Protection Agency (U.S.EPA) convinced industry to voluntarily stop or restrict production of PFOA, PFOS, their precursors, and other related compounds between 2000 and 2007. ,, Although the production of these PFAS was reduced by 95% in 2010, PFOS and PFOA remain prevalent in the environment in the United States due to historical pollution, and they continue to be produced in some countries worldwide. ,,, A 2020 study in Japan found that 100% of over 12 000 sampled mothers had PFOS measured in their serum . A recent report on European PFAS exposure reported PFAS with the highest levels in human serum are PFOS (∼65% of total PFAS in adults, ∼35% of total PFAS in children) and PFOA (∼15% of total PFAS in adults, ∼35% of total PFAS in children) .…”

Per- and polyfluoroalkyl substances (PFAS) are a group of persistent environmental pollutants that are ubiquitously found in the environment and virtually in all living organisms, including humans. PFAS cross the blood–brain barrier and accumulate in the brain. Thus, PFAS are a likely risk for neurotoxicity. Studies that measured PFAS levels in the brains of humans, polar bears, and rats have demonstrated that some areas of the brain accumulate greater amounts of PFAS. Moreover, in humans, there is evidence that PFAS exposure is associated with attention-deficit/hyperactivity disorder (ADHD) in children and an increased cause of death from Parkinson’s disease and Alzheimer’s disease in elderly populations. Given possible links to neurological disease, critical analyses of possible mechanisms of neurotoxic action are necessary to advance the field. This paper critically reviews studies that investigated potential mechanistic causes for neurotoxicity including (1) a change in neurotransmitter levels, (2) dysfunction of synaptic calcium homeostasis, and (3) alteration of synaptic and neuronal protein expression and function. We found growing evidence that PFAS exposure causes neurotoxicity through the disruption of neurotransmission, particularly the dopamine and glutamate systems, which are implicated in age-related psychiatric illnesses and neurodegenerative diseases. Evaluated research has shown there are highly reproduced increased glutamate levels in the hippocampus and catecholamine levels in the hypothalamus and decreased dopamine in the whole brain after PFAS exposure. There are significant gaps in the literature relative to the assessment of the nigrostriatal system (striatum and ventral midbrain) among other regions associated with PFAS-associated neurologic dysfunction observed in humans. In conclusion, evidence suggests that PFAS may be neurotoxic and associated with chronic and age-related psychiatric illnesses and neurodegenerative diseases. Thus, it is imperative that future mechanistic studies assess the impact of PFAS and PFAS mixtures on the mechanism of neurotransmission and the consequential functional effects.

“…Carbonate strata are essential for the hydrocarbon industry, because they contain approximately 70% of the global hydrocarbon reserve, 50% of the proved recoverable reserve, and 60% of the hydrocarbon production [1][2][3][4]. Hydrocarbon exploration of marine carbonate has been conducted in China for more than 40 years, and several large marine gas fields, including the Weiyuan [5][6][7], Puguang [8,9], Longgang [10,11], and Yuanba [12,13] have been discovered in the Sichuan Basin located in the Upper Yangtze Platform [14][15][16][17][18]. As an extension of the Lower Yangtze Platform in the eastern area, the South Yellow Sea Basin (SYSB) is a multi-cycle superimposed basin on the Pre-Sinian metamorphic basement (Fig 1a).…”

Mesozoic-Palaeozoic marine carbonate rocks are important hydrocarbon reservoirs in the Central Uplift area of the South Yellow Sea Basin (SYSB). Due to the lack of boreholes and the great heterogeneity of carbonate reservoirs, the distribution of porous carbonate reservoirs and their related key controlling factors remain unclear. Based on seismic inversion and isotope analysis, this study explores the factors affecting the distribution of porous Carboniferous-Early Permian carbonate reservoirs in the SYSB. In this study, the log-seismic characteristics of porous carbonate reservoirs, sensitive lithology parameters, and physical property parameters are extracted and analyzed. The pre-stack simultaneous inversion technique is applied to predict the lithology properties and physical properties of the porous carbonate reservoirs. Moreover, the sedimentary of carbonate is analyzed using isotopes of carbon, oxygen, and strontium. The results indicate that porous carbonate reservoirs with porosities of 3%~5% mainly occur at the paleo-highland (Huanglong Formation and Chuanshan Formation) and the slope of paleo-highland (Hezhou Formation). The porous carbonate reservoirs of the Qixia Formation are only locally developed. In addition, the study area was dominated by a warm and humid tropical climate from the Carboniferous to Early Permian, with four sea-level eustatic fluctuation indicated by the negative and positive δ13C excursions. When the sea level fell, the study area was exposed and denuded, and the supply of terrigenous detrital was dominated, which significantly influenced the carbonate deposit and diagenesis. This study highlights that sedimentation was a key factor in controlling the quality of Carboniferous-Early Permian carbonate reservoirs. The methods proposed in this study can be used in other carbonate-dominated strata worldwide.
