Association between short-term ambient temperature variability and depressive symptoms: using staggered adoption of low-carbon city program in China as a quasi-natural experiment
AbstractGrowing epidemiological evidence has shown that ambient temperature variability (TV) contributes to multiple health problems. However, whether short-term TV affects mental health remains unclear. Based on a nationally representative cohort sample from 2011 to 2018 in China, this study linked monthly TV with depressive symptoms. City-level data on daily temperature for 1 month prior to the survey date were collected. The TV in 1 month for each participant, measured by the standard deviations (SDs) of daily humidex, daily mean temperature, daily minimum temperature, and daily maximum temperature, was calculated ba...

A new efficiency calibration methodology for different atmospheric filter geometries by using coaxial Ge detectors
AbstractThe study of the different pollutants present in atmospheric aerosols such as trace elements and radionuclides is essential to assess the air quality. To analyze the particulate matter (PM), atmospheric filters with different dimensions and geometries (rectangular, circular, slotted, and square filters) are usually employed. Regarding the pollutants existing in atmospheric aerosols, radionuclides are usually analyzed due to their multiple applications such as either in the environmental radiological control or as tracers of atmospheric processes. Therefore, this study aims to develop a new and general methodology t...

Oceanic and atmospheric anomalies associated with extreme precipitation events in China 1983 –2020
AbstractObserved synoptic anomalies in connection with China ’s extreme precipitation events/floods in the summers of 1982/83, 1997/98, 2010, 2014, 2015/16, and 2020 are studied. These events mainly occur within the middle and lower Yangtze basins. The dominant moisture source is the Northern Indian Ocean and the Southwestern Pacific Ocean of the Indo-Pacif ic warm pool (IPWP). Both of these bodies of water have warmed since 1979. In East Asia, the strong land‐sea thermal contrast driven by global warming drives the increased East Asian summer monsoon (EASM) circulation, which develops deep convective precipitation. Th...

Air pollution situation in small towns, including winter resorts: a comparative study of three cases in Northern Europe
AbstractIn Europe, emissions of many air pollutants have decreased in recent decades, but there exist sites where concentrations of pollutants are still high and have become a public health problem. The air quality monitoring networks include urban stations in big cities and rural background stations. Main pollutants (SO2, NOx, CO, particulate matter) are measured automatically and reported on hourly basis, but there is very few research about air quality in small towns. The small towns are important transport nodes between cities and nowadays they are growing bigger, often being focused on seasonal tourism. In this paper,...

Source apportionment of air pollution in urban areas: a review of the most suitable source-oriented models
AbstractNotwithstanding the improvements already achieved in recent decades through regional and urban scale actions implemented across Europe, air pollution is still a major environment and health concern for Europeans. The quantitative assessment of the different sources of air pollution in regional/urban areas is crucial to support the design of accurate air quality plans. Source apportionment techniques are capable to relate air pollutant concentrations to existing emission sources activities and regions. The selection of the appropriate source apportionment technique to apply to a given area should take into account t...

Impact of traffic on air pollution in a mid-sized urban city during COVID-19 lockdowns
This study demonstrated that COVID-19 lockdowns in Milwaukee, WI, caused significant decreases in traffic, which in turn had a direct impact on air pollutants. It also highlights the need for traffic volume and air quality data at relevant spatial and temporal scales for accurately assessing source apportionment of combustion-based air pollutants, which cannot be captured with typical ground-based sensor systems.

How do temperature and precipitation drive dengue transmission in nine cities, in Guangdong Province, China: a Bayesian spatio-temporal model analysis
In this study, we aim to quantify the effect of climatic factors on dengue in nine cities of the Pearl River Delta (PRD) in South China. Monthly dengue cases, climatic factors, socio-economic, geographical, and mosquito density data in nine cities of the PRD from 2008 to 2019 were collected. A generalized additive model (GAM) was applied to investigate the exposure –response relationship between climatic factors (temperature and precipitation) and dengue incidence in each city. A spatio-temporal conditional autoregressive model (ST-CAR) with a Bayesian framework was employed to estimate the effect of temperature and prec...
