With the continuous acceleration of urbanization, air pollution has become an increasingly serious threat to public health. Strengthening detection and control pollutants a focal point in current society. In light increasing amount literature field with every passing year, numerous reviews have been compiled; however, only limited number employ bibliometric methods comprehensively review summarize research trends this field. Herein, study utilizes two analysis tools, namely, CiteSpace (6.1.R6) VOSviewer (1.6.20), conduct visual comprehensive spanning 2000 2023. By doing so, it establishes knowledge framework for on control. Simultaneously, collaborative network analysis, reference co-citation keyword co-occurrence prominence are employed undertake exhaustive profound examination within domain. Results indicate that, over time, relevant papers exponentially increased, while interdisciplinary cooperation gradually formed. Additionally, describes key areas research, including residue treatment, regional joint control, mechanism analysis. Finally, challenges faced by researchers their different perspectives discussed. To better integrate findings we explore correlations among data systematically present developmental trends. This confirms nature hope its guiding future.

Abstract. As a key source of hydroxyl (OH) radicals, nitrous acid (HONO) has attracted much attention for its important role in the atmospheric oxidant capacity (AOC) increase. In this study, we made comparison ambient levels, variation patterns, sources, and formation pathway warm season (from June to October 2021) on basis continuous intensive observation an urban site Beijing. The monthly average mixing ratios HONO were 1.3, 1.0, 0.96, 0.89 ppb, respectively, showing larger contribution OH radicals relative ozone daytime. emission factor (EF) NOx from vehicle emissions was estimated be 0.017, higher than most studies conducted nocturnal NO2/HONO conversion frequency kHONO 0.008 h−1. season, missing HONO, Punknown, around noontime 0.29–2.7 ppb According production rate also very AOC. This work highlights importance AOC while encouraging long-term assess sources over time compared capture pollution processes.

The atmospheric oxidizing capacity is the most important driving force for chemical transformation of pollutants in atmosphere. Traditionally, mainly depends on concentration O3 and other gaseous oxidants. However, based gas-phase oxidation cannot accurately describe explosive growth secondary particulate matter under complex air pollution. From perspective, comes from activation O2, which can be achieved both interfacial processes. In heterogeneous or multiphase formation pathways matter, enhancement ascribed to O2/H2O-involved hydrolysis processes an unrecognized source capacity. Revealing enhanced due high-concentration environments its contribution pollution are critical understanding haze chemistry. accurate evaluation also scientific basis implementation PM2.5 collaborative control China around world.

Abstract Atmospheric chemistry research and atmospheric measurement techniques have mutually promoted each other developed rapidly in China recent years. Cavity-based absorption spectroscopy, which uses a high-finesse cavity to achieve very long path-length, thereby achieving ultra-high detection sensitivity, plays an extremely important role research. Based on the Beer–Lambert law, this technology has unique advantages of being non-destructive, chemical-free, highly selective. It does not require any sample preparation can quantitatively analyze trace gases real time situ. In paper, we review following: (1) key technological advances different cavity-based spectroscopy techniques, including ring-down cavity-enhanced attenuated phase shift their extensions; (2) applications these reactive species, such as total peroxy radical, formaldehyde, nitrogen (e.g., NO x , HONO, nitrates, alkyl nitrates). The systematically introduces chemistry, will help promote further communication cooperation fields laser chemistry.
