13 Project: DUSTRISK - A risk index for health effects of mineral dust and associated microbes
Execution dates: 01-05-2020 to 30-04-2023 (36 Months):
Coordinator: Khanneh Wadinga Fomba (E-mail: [email protected] ) Participating Institutions: TROPOS and Leibniz ((Microbiology, DSMZ); (Biophysics, FZB, ); (Toxicology, IUF)) /Cape Verde: ((Chemist, Epidemiologist, UniCV); INMG; (Pulmonologist, Hospitals); DNA; INSP) Funding Entity: Leibniz Institute for Tropospheric Research e.V Funding line: Leibniz collaborative excellence Main Scientific Goal: Develop a dust-health-risk-index by evaluating the health effects of dust and associated microbes on respiratory diseases. Added-values: (1)Interdisciplinary network of Leibniz and international experts collaborating to establish scientific tools that can improve on public health (2)Consolidates existing Leibniz topic “Infections 21” (3)The risk-index is a good example of transfer of scientific outcomes to useful societal products (4)Provides opportunity for capacity building and new transdisciplinary research in the fields of public health, toxicology and atmospheric sciences (5)Strengthen international collaboration providing new insights into health effects of dust and associated microbes

18 How to observe pollution (PM and gases) • Remotely – Satellites or ground based Sun photometers (AERONET) • In situ
19 Why Space and Satellites for Pollution monitoring ? • Continuous temporal sampling; • Continuous spatial sampling; • Global coverage to initialize and evaluate predictive models; • Long-time series (back to 1978) for Aerosols; • Identify trends and patterns (globally,regionally); • Could be used to drive policy.
20 December 4, 2015 Space and Cape Verde
21 Satellite Aerosol Optical Depth – identifies lots of dust particles
22 Satellite Limitations and particulate matter observations
• Cloud coverage • Night conditions • Temporal coverage (satellite overpass time)- does it pass over when there is pollution. • Spatial coverage (urban pollution) • What are the surface PM concentrations?
23 Satellite Problem of night and clouds
24 December 4, 2015 Space and Cape Verde
25 Cape Verde (December 4, Dec 7, 2015)
26 Why we need real-time networks of particulate matter to quantify AQ • Fast growing megacities; • Localized sources of pollution (e.g.waste sites); • Limited access to health care in some locations (rural zones); • Provides information at local to regional scales for decision-makers ; • Evaluation of satellites and PM forecasts; • Poor Air Quality is natural hazard and level of the threat should be communicated to the public.
27 Real-time Insitu PM measurements can support satellites but limited in Africa

42 Air Quality networks require collaboration across Disciplines and space • Regional networks: (Senegal, the Gambia, Cabo Verde); (Nigeria, Niger, Burkina Faso, Ghana, Ivory Coast) are ideal to develop regional health-pollution partnerships; – Doctors, researchers, students, community participatory research and partnership; – Coordinated Public campaigns (national asthma week, national pollution week) COVID-19 and Air Pollution
• Air quality remains a factor in driving co- morbidities such as respiratory and cardiovascular disease in Africa and the Southern Hemisphere over the next few months: – Levels of Air quality over the last few months. – Biomass burning Southern Hemisphere; – Long range transport of Saharan dust to the Caribbean May-September. – Wet season disease in West Africa (Vector and water borne disease, Asthma and Acute respiratory disease)

49 Ideas for AIR network to address to be done • Expansion of PM monitoring network across Africa; - megacities, pollution zones; • Capacity Building – workshops and pilot projects using Earth observations (satellite and public health); • Evaluation of predictive tools and other tools for analysis; • Develop framework for communicating hazards to public and across disciplines in real-time via social networks and mobile phone apps; • Support linkages between environment and health for cardiovascular, NC and Communicable respiratory and infectious disease; • Support workshops to develop policy – energy usage, air quality as natural hazards, health impacts, community partnership.
