Associations of ambient exposure to benzene, toluene, ethylbenzene, and xylene with daily mortality
Ozone-related acute excess mortality projected to increase in the absence of climate and air quality controls consistent with the Paris Agreement
The International Global Atmospheric Chemistry project comments on the revised WHO air quality guidelines
In September 2021, the World Health Organization (WHO) announced updated global air quality guidelines providing health-based targets for six key air pollutants [1]. The annual targets for pollutant concentrations were reduced fourfold for nitrogen dioxide (NO2) to 10 μg m−3 and by 50% and 25% respectively for the mass concentration of particles smaller than and equal to 2.5 μm (PM2.5) and 10 μm (PM10) to 5 μg m−3 and 15 μg m−3. New targets were …
Key challenges for tropospheric chemistry in the Southern Hemisphere
This commentary paper from the recently formed International Global Atmospheric Chemistry (IGAC) Southern Hemisphere Working Group outlines key issues in atmospheric composition research that particularly impact the Southern Hemisphere. In this article, we present a broad overview of many of the challenges for understanding atmospheric chemistry in the Southern Hemisphere, before focusing in on the most significant factors that differentiate it f…
Respiratory health among adolescents living in the Highveld Air Pollution Priority Area in South Africa
Adolescents living in air polluted areas experience adverse health impacts Future research should interrogate long-term exposure and health outcomes among adolescents living in the air polluted environment
Ambient Particulate Air Pollution and Daily Mortality in 652 Cities
BACKGROUND: The systematic evaluation of the results of time-series studies of air pollution is challenged by differences in model specification and publication bias. METHODS: ) with daily all-cause, cardiovascular, and respiratory mortality across multiple countries or regions. Daily data on mortality and air pollution were collected from 652 cities in 24 countries or regions. We used overdispersed generalized additive models with random-effects…
Students’ Perceived Heat-Health Symptoms Increased with Warmer Classroom Temperatures
Temperatures in Africa are expected to increase by the end of the century. Heat-related health impacts and perceived health symptoms are potentially a problem, especially in public schools with limited resources. Students (n = 252) aged ~14-18 years from eight high schools completed an hourly heat-health symptom log over 5 days. Data loggers measured indoor classroom temperatures. A high proportion of students felt tired (97.2%), had low concentr…
Projections of rapidly rising surface temperatures over Africa under low mitigation
An analysis of observed trends in African annual-average near-surface temperatures over the last five \ndecades reveals drastic increases, particularly over parts of the subtropics and central tropical Africa. \nOver these regions, temperatures have been rising at more than twice the global rate of temperature \nincrease. An ensemble of high-resolution downscalings, obtained using a single regional climate \nmodel forced with the sea-surface temp…
Regional Projections of Extreme Apparent Temperature Days in Africa and the Related Potential Risk to Human Health
Regional climate modelling was used to produce high resolution climate projections for Africa, under a "business as usual scenario", that were translated into potential health impacts utilizing a heat index that relates apparent temperature to health impacts. The continent is projected to see increases in the number of days when health may be adversely affected by increasing maximum apparent temperatures (AT) due to climate change. Additionally, …
A laboratory investigation of the relative humidity dependence of light extinction by organic compounds from lignin combustion
Light extinction by atmospheric particles is strongly dependent on the size, chemical composition, and water content of the aerosol. Since light extinction by particles directly impacts climate and visibility, measurements of the extinction at various relative humidities (RHs) are needed. In this work, the optical growth factors, fRHext (80%RH, Dry) have been measured using cavity ring-down aerosol extinction spectroscopy at 532 nm for particles …
