Every year, the Caribbean basin is strongly impacted by sand mists from African deserts. The health impact is significant for the population living there. This is the reason why a better understanding of the behavior of particulate matter that have an aerodynamic diameter less than 10 µm diameter (PM10) is crucial to predict their fluctuations. The...

The aim of this study was to model the behavior of particles with aerodynamic diameter lower or equal to 10 µm (PM10) in the Caribbean area according to African dust seasonality. To carry out this study, PM10 measurement from Guadeloupe (GPE) and Puerto Rico (PR) between 2006 and 2010 were used. Firstly, the missing data issues were addressed using...

Due to African dust, the Caribbean area is known to have one of the highest incidences of asthma on the planet. Consequently, it is crucial to dissociate the impact of local sources from large scale sources in this region. The aim of this study was to estimate the PM10 detection threshold for dusty events using a statistical approach and a dynamic...

In this study, we investigate the interactions between particulate matter that have an aerodynamic diameter less than 10 µm diameter (PM10) and rainfall (RR) in entropy framework. Our results showed there is a bidirectional causality between PM10 concentrations and RR values. This means that PM10 concentrations influence RR values while RR induces...

Dear Colleagues, Particulate matter is one of the most studied air pollutants in the literature due to its adverse health effects. Several epidemiological studies have already associated it with cardiovascular and respiratory diseases, prematurity, general mortality and a series of infectious diseases. This particulate matter can come from natural...

In the literature, it is well known that mineral dust play a key role in the atmospheric radiation budget. How to identify the cause–effect relationship between mineral dust and climatic parameters remains a crucial issue in atmospheric science and environment. In this study, the causal relation between particulate matter that have an aerodynamic d...

In the literature, several epidemiological studies have already associated respiratory and cardiovascular diseases to acute exposure of mineral dust. However, frail people are also sensitive to chronic exposure to particulate matter with an aerodynamic diameter 10 μm or less (𝑃𝑀10). Consequently, it is crucial to better understand 𝑃𝑀10 fluctuations...

Environmental pollution management is one of the most important features in pollution risk assessment. Several studies have shown that exposure to particulate matter with an aerodynamic diameter of 10 μm or less, i.e. PM10, were associated to adverse health effects. To our knowledge, no study has yet investigated the modelling of PM10 frequency dis...

In the Caribbean, most of the waste is stored in open landfills without biogas collection systems. Several models projecting methane emissions from landfills have been proposed in the literature. Few studies have made use of them in tropical areas. The Landfill Gas Emissions Model (LandGEM) and the Afvalzorg model are among the conventional models...

Concentrations of airborne Volatile Organic Compounds (VOCs) were evaluated by monitoring landfill gases at the main municipal solid waste of Guadeloupe archipelago. Opened in 1973, the open landfill of La Gabarre is still operated nowadays. Over last decade, nature of stored waste and landfill configuration have evolved. Before 2008, waste was jus...

Dispersion of pollutants in the atmosphere strongly depends on its stability. In nocturnal stable conditions, occurrence of a surface thermal inversion can trap air pollutants near the ground. Such inversion develops after sunset consecutively to radiative cooling of the ground and is dissolved by convection in the morning. In literature, few studi...

In 2003, the VOC emissions coming from “La Gabarre”, the main open landfill in Guadeloupe, located in-between an urban area and a mangrove, were identified and quantified with a portable FTIR spectrometer. In 2004, COVs found at nighttime in the urban area nearby confirmed why residents complain about. As part of this thesis, portable mass spectrom...

Temperature inversions play a significant role in air quality. Among the different types of inversions, surface inversions trap pollutants in the lower atmosphere. By clear sky it develops in the late afternoon and is dissolved in the morning with the heated ground. In the tropics there are few measurements of this phenomenon. With a SODAR (SOund D...

Habituellement l'archipel de la Guadeloupe est considérée comme un ensemble d'îles soumis à un flux d'alizés sans circulation thermique endogène [1]. Cependant, la configuration topographique de l'archipel, en particulier la côte au vent de la Basse Terre qui culmine à 1467 m, laisse envisager l'apparition de circulations thermiques. En effet, des...

People spend a larger part of their time indoor than outdoor and are most exposed to the indoor air pollution. One of the major contaminants of indoor environment is airborne particulate matter. In fact, the airborne particles with an aerodynamic size smaller than 10 µm are inhalable and penetrate more or less deeply into the human respiratory syst...

Dear Colleagues, Particulate matter is one of the most studied air pollutants in the literature due to its adverse health effects. Several epidemiological studies have already associated it with cardiovascular and respiratory diseases, prematurity, general mortality and a series of infectious diseases. This particulate matter can come from natural or anthropogenic sources. The impacts of climate change in desert regions and increasing industrialization and urbanization are some of the causes of increasing concentrations of particulate matter in the atmosphere in the last few decades. Therefore, it is crucial to improve knowledge about the behavior of particulate matter in order to develop strategies and build tools to predict its concentration. Given the scientific community’s keen interest in this pollutant, the open-access journal Atmosphere is hosting a Special Issue to showcase the most recent findings related to the sources, characterization and control of particulate matter. Whatever the origin and size of the particles, all papers using field measurements, remote sensing, soundings and models are welcome. These articles can cover areas ranging from local to synoptic scale. With the recent increase in the number of volcanic eruptions around the world, this Special Issue is also a suitable place for articles that discuss particulate matter in ash and its impact on human health. We look forward to collaborating with you and to hearing back from you soon. Best regards, Guest Editors: Dr. Thomas Plocoste (KaruSphère), Pr.
