Biogenic volatile organic compounds are emitted into the atmosphere where they can oxidize forming compounds with lower volatilities. These low-volatility compounds can participate in the formation of secondary organic aerosols (SOAs) that ...
Hot and dry conditions elevate grass pollen and sub-pollen particle concentrations in Melbourne, Australia [0.03%]
在澳大利亚墨尔本,热干条件下草花粉和次级气传颗粒浓度升高

C B A Mampage et al.
A Wideband Integrated Bioaerosol Sensor (WIBS) was used in conjunction with chemical tracer analysis for the first time during the 2022-2023 grass pollen season in Melbourne, Australia. WIBS detected continuous levels of bioaerosol througho...
Utility of low-cost sensor measurement for predicting ambient PM2.5 concentrations: evidence from a monitoring network in Accra, Ghana [0.03%]
低成本传感器测量预测环境PM2.5浓度的效用:来自加纳首都阿克拉监测网络的证据

Patrick Attey-Yeboah et al.
Ambient air pollution has been linked to several health endpoints. The WHO attributes 7 million deaths annually to air pollution with particulate matter (PM2.5) being the pollutant of critical importance due to its devastating health effect...
A diagonal volatility basis set to assess the condensation of organic vapors onto particles [0.03%]
一种对角线挥发性基集,用于评估有机蒸汽在颗粒上的凝结情况
Brandon Lopez,Nirvan Bhattacharyya,Jenna DeVivo et al.
Brandon Lopez et al.
We present a "diagonal" Volatility Basis Set (dVBS) comparing gas-phase concentrations of oxygenated organic molecules (OOM) to their condensed-phase mass fractions. This permits closure of vapor concentrations with particle composition con...
Across land, sea, and mountains: sulphate aerosol sources and transport dynamics over the northern Apennines [0.03%]
横越陆地、海洋和山脉:北部阿普安阿尔卑斯山区硫酸盐气溶胶源及传输动力学

Manuel Bettineschi et al.
In this study, we combine aerosol observations with high-resolution Eulerian (WRF-CHIMERE) and Lagrangian (FLEXPART) modelling to investigate the source regions, emission sources, transport pathways, and chemical transformation of sulphate ...
Subtropical southern Africa fire emissions of nitrogen oxides and ammonia obtained with satellite observations and GEOS-Chem [0.03%]
利用卫星观测和GEOS-Chem 模型得到的南部非洲亚热带地区氮氧化物和氨气排放量估算
Eloise A Marais,Martin Van Damme,Lieven Clarisse et al.
Eloise A Marais et al.
Landscape fires in subtropical southern Africa (2-20°S) are a prominent regional source of nitrogen oxides (NO x ) and ammonia (NH3), affecting climate and air quality as precursors of tropospheric ozone and aerosols. Here we evaluate GEOS...
Laboratory development and validation of vapor phase PFAS methods for soil gas, sewer gas, and indoor air [0.03%]
实验室开发和验证土壤气体、污水气体和室内空气挥发性PFAS物质的方法
Heidi Hayes,Chris Lutes,Nicola Watson et al.
Heidi Hayes et al.
There is no standard sampling and analysis method for vapor phase per- and polyfluoroalkyl substances (PFAS) that can be routinely applied to soil gas, sewer/conduit gas, and indoor air samples. We have validated a thermal desorption GC/MS/...
CyanoHABs and CAPs: assessing community-based monitoring of PM2.5 with regional sources of pollution in rural, northeastern North Carolina [0.03%]
