Exposure to airborne particulates is estimated as the largest cause of premature human mortality worldwide and particular concern in sub-Saharan Africa where emissions are high data lacking. Particulate matter (PM) contains several toxic organic species including polycyclic aromatic hydrocarbons (PAHs) nitrated PAHs (NPAHs). This study provides first characterization source identification for PM10- PM2.5-bound NPAHs during a three-month period that spanned dry wet seasons at three locations...
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 Hemisphere. In this article, we present a broad overview of many challenges for understanding chemistry Hemisphere, before focusing on most significant factors differentiate it Northern We sections importance biogenic emissions and fires showing these often dominate over...
Indoor air pollution presents a significant global health risk, yet the influence of outdoor and meteorological factors on indoor quality is not well understood. This study investigates these impacts in 88 naturally ventilated households across urban, suburban, industrial areas, with no smoking or cooking. Air measurements were continuously recorded for 24 h day over six consecutive days during wet season. The findings reveal that PM 2.5 levels consistently exceeded levels, weekday...
A lack of long-term air quality monitoring data in African countries such as Rwanda poses a significant challenge urbanization leads to declining quality. This study uses four years on particulate matter pollution (PM2.5) understand the current drivers pollution, success interventions and potential for further actions. PM2.5 were collected using low-cost reference monitors two sites Kigali. Results show that levels Kigali exceeded recommended WHO guidelines. Using COVID-19 lockdown natural...
Schoolchildren are a high-risk population, and their exposure to air pollution at school has been documented in high-income countries. As result, siting policies protect children from have established those Such are, however, non-existent Africa where the problem is growing gravely under-studied due lack of funding install reliable ground-level monitoring networks quality standards. The present study, first its kind be conducted Africa, measured Black Carbon (BC) related sources: fossil...
Abstract Air pollution in Africa is a significant public health issue responsible for 1.1 million premature deaths annually. Sub-Saharan has the highest rate of population growth and urbanization any region world, with substantial potential future emission worsening air quality. Accurate extensive observations meteorology atmospheric composition have underpinned successful mitigation strategies Global North, yet general East particular remain among most sparsely observed regions world. This...
Household air pollution from biomass cookstoves is a major concern in low- and middle-income countries because it may be linked with increasing rates of metabolic disorders such as diabetes. We assessed cross-sectional associations between household concentrations glycated hemoglobin (HbA1c) levels. analyzed data 346 women 40 to <80 years age who cooked fuel were enrolled the Air Pollution Intervention Network (HAPIN) Trial Guatemala, India, Peru, Rwanda. explored 24-h average personal...
Exposure to household air pollution from the combustion of solid fuels is a leading risk factor for death and disease in low- middle-income countries, where cleaner cooking lighting options are often unavailable. Few studies have measured personal exposure during pregnancy, sensitive period development, particularly Africa. We aimed characterize early midpregnancy among women Rwanda assess predictors exposure, including stove fuel type, behaviors, housing conditions, sociodemographic...
Abstract Lead (Pb) and cadmium (Cd) are metals that occur naturally in the environment present biomass fuels, such as wood. When these fuels burned, they can release Pb Cd into air, leading to exposure through inhalation. Studies of health outcomes suggest harmful impacts, including cardiovascular diseases. We assessed baseline associations between concentrations dried blood spots with systolic diastolic pressure (SBP, DBP) among women Household Air Pollution Intervention Network (HAPIN)...
Noise pollution poses a serious threat to public health and continues grow in extent, frequency, severity due the rapid population growth urbanization, this is of particular concern developing countries such as Rwanda. However, data on noise levels, laws regulations are, however, lacking We assessed effect land-use type during two-month period at nine sites: three commercial sites, passenger-car parking two road junction one reference site (Car-Free Zone) collected weekdays (Monday,...
Bioaerosols are ubiquitous and play a significant role in global climate human health due to inhalation exposure. Passive air sampling of bioaerosols, as complementary method active using pumps, is increasingly valued its simplicity, electricity-free operations, cost-effectiveness providing time-integrated samples over weeks/months. In this study, polyurethane foam disk passive samplers (PUF-PAS), dry deposition (PAS-DDs), high-volume (Hi-Vol) were deployed Toronto the Athabasca oil sands...
<title>Abstract</title> Despite mounting evidence that heatwaves aggravate urban air pollution, with substantial impacts on public health, comparatively little research has addressed Sub-Saharan African contexts. In this study, we focused Kigali, Rwanda, to assess the relationship between extreme heat events and concentrations of fine particulate matter (PM₂.₅), nitrogen dioxide (NO₂), ozone (O₃) from 2021 2024. Using low-cost sensors for dense spatiotemporal coverage, our analysis found O₃...
Landslides are among hazards that undermine the social, economic, and environmental well-being of vulnerable community. Assessment landslides vulnerability reveals damages could be recorded, estimates severity impact, increases preparedness, response, recovery, mitigation as well. This study aims to estimate for western province Rwanda. Field survey secondary data sources identified 96 used prepare a inventory map. Ten factors-altitude, slope angles, normalized difference vegetation index...
Landslides hazard mapping (LHM) is essential in delineating prone areas and optimizing low cost mitigation measures. This study applied the Geographic Information System statistical index method LHM Rwanda. Field surveys identified 336 points that were employed to construct a landslides inventory map. Ten predicting factors analyzed: normalized difference vegetation index, elevation, slope, aspects, lithology, soil texture, distance rivers, roads, rainfall, land use. The factor variables...
The incomplete combustion of fossil fuels from petrol, natural gas, and fuel oil in the engine vehicles contributes to air quality degradation through traffic-related pollutant emissions. Real-time affordable multi-pollutant (RAMPs) monitors were installed Kigali, capital Rwanda, fill gap datasets. Using RAMPs, this is first modelling research Rwanda aiming report concentration NO2 by comparing In-situ monitored data modelled results. We targeted emissions 27 road networks Kigali address...
