Aerosols, Aeroallergens, and Health

The harmful consequences of air pollution are important, both for health and for the environment. The countries of West Africa are not spared by air pollution, given the development of cities, rapid urbanization, high population growth, important industrial activities, poorly organized transport system with very advanced age vehicles associated with poor fuel quality, as well as domestic activities (biomass burning for cooking) and peri-urban agricultural activities (pesticides and fertilizers). In the current context of Senegal located in the Sahelian zone, the main pollutants at the origin of this degradation of air quality are desert dust. Added to this is anthropogenic pollution related to automobile traffic and industries. Particulate pollution occupies an important place. These particulate pollutants are generally subdivided into two broad classes, namely fine particles and coarse particles. Fine particles (PM2.5) are recognized, through epidemiological studies as being associated with various pathologies, asthma especially in children and chronic obstructive pulmonary disease (COPD) which affects both the child and the child. adult (Boublil et al., 2013, Gualtieri et al., 2010, Michael, Montag and Dott, 2013). These fine particles are capable of adsorbing on their surface volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs) and promoting the formation of reactive oxygen species (ROS), thus leading to the induction of stress. oxidant in cells, inflammatory responses, DNA damage and cell death (Dergham et al., 2015; Gualtieri et al., 2010; Okuda, 2013; Reche et al., 2012). They are also known for their cytotoxic and pro-inflammatory properties (Camatini, Corvaja, Pezzolato, Mantecca and Gualtieri, 2012, Gualtieri et al., 2010, Longhin et al., 2013). Center for air quality management was created in 2009 to allow an assessment of this pollution in the city of Dakar. The network has 6 measuring stations and a mobile laboratory. Its objectives are:

• keep on watching the ambient air pollution,
• Inform the public on air quality and provide reports to the authorities for decision making,
• Advocate realistic measures for improving air quality,
• Promote the establishment of a committee on air quality.

Being assistant insurance / quality control, I participate:

• Daily data retrieval, data quality control and corrections;
• Preparing standard operating procedures and ensuring that they are applied;
• Preparation and monitoring of quality assurance procedures on air quality data.
• Weekly execution of the calibration of all instruments in the field
• Maintenance and repair of instruments

I look forward to this conference in addition to the exchanges with experts on air quality management, a capacity building for:

• Control of air quality monitoring,
• Analysis, prediction of air quality,
• Designing effective emission reduction strategies,
• Assessment of health effects to better understand the physiopathological mechanisms underlying aerosol exposure.
