According to online monitoring data on atmospheric ozone and the pollution characteristics of its precursors obtained in Jinan June 2021, we analyzed different sites: urban sites (city station, Quancheng Square), an industrial park site (oil refinery), a suburban (Paomaling). The relative incremental reactivity was calculated using photochemical observation-based model explore sensitivity O3 ge...

Volatile organic compounds (VOCs), with negative impacts on the aquatic ecosystem, are increasingly released into environment by anthropogenic activities. Water samples were collected from five areas of Han River Watershed (HRW) tributaries, South Korea, to detect 11 VOCs, which classified as halogenated aliphatic hydrocarbons (HAHs) and aromatic (AHs). Among 1,1-dichloroethylene, 1,1,1-trichlo...

Volatile organic compounds (VOCs) in the atmosphere play significant roles in secondary organic aerosol (SOA) and ground-level ozone (O3) formation. Emission inventories of biogenic VOCs (BVOCs) and anthropogenic VOCs (AVOCs) for 2013 in China were developed at a spatial resolution of 36km×36km. The monthly emission inventory of BVOCs were established using MEGAN2.1 driven by WRF model, based o...

Quantification of volatile organic compounds (VOCs) in environmental air has been recently focused because of their adverse effects on human health, including the so−called multiple chemical sensitivity and sick building syndrome [1,2]. To investigate the effect of VOCs on human health and prevent the above illnesses, a sensitive and reliable method for determining the VOCs in air samples is de...

National Water-Quality Assessment (NAWQA) Program collected or compiled data on ground water from 1926 private wells in rural areas across the United States from 1986 to 1999. These private wells, also called domestic wells, are owned and operated by the homeowners and provide water for household uses, including drinking, food preparation, watering lawns and gardens, bathing, and washing clothe...

In our present study we tested the health effects among women of controlled exposures to volatile organic compounds (VOCs), with and without ozone (O3), and psychological stress. Each subject was exposed to the following three conditions at 1-week intervals (within-subject factor): VOCs (26 mg/m3), VOCs + O3 (26 mg/m3 + 40 ppb), and ambient air with a 1-min spike of VOCs (2.5 mg/m3). As a betwe...

Abstract This study aims to analyze the sensitivity of volatile organic compounds (VOCs) ambient concentrations fine particles (PM 2.5 ) in representative industrial city Ulsan, Korea. For calculation coefficients between VOCs and PM (SVOCs-PM ), data were obtained from an air quality monitoring station, their corresponding 6-h average (alkanes, alkenes, aromatics, total VOCs) measured at Yeong...

D iscussion of the potential sensitivity of air quality to climate change has increased in recent years. In 2001, the NRC (acronyms defined in Table 1) posed the question “to what extent will the United States be in control of its own air quality in the coming decades?” noting that “. . . changing climatic conditions could significantly affect the air quality in some regions of the United State...

Hundreds of volatile organic compounds (VOCs) are emitted from the human body, and the components of VOCs usually reflect the metabolic condition of an individual. Therefore, contracting an infectious or metabolic disease often results in a change in body odour. Recent progresses in analytical techniques allow rapid analyses of VOCs derived from breath, blood, skin and urine. Disease-specific V...

Currently, air pollution is being exacerbated by rapid social, economic, and industrial development. Major pollutants include volatile organic compounds (VOCs) CO. Photocatalytic thermocatalytic technology can be used to convert VOCs CO into harmless gases effectively. Recently, photothermal synergistic catalysis has aroused much attention because of its higher performance than those individual...
