Abstract:
People living in unsanitary conditions are exposed to faecal microorganisms through various pathways. This study conducted an exposure analysis of E. coli and parasite eggs in a rural village of Vietnam where people use human manure for agriculture and in a slum of Bangladesh. The study was done in a probabilistic manner, using Monte Carlo simulation, and considered multiple pathways of exposure, such as intentional/accidental ingestion of drinking water, hygiene water, environmental water, food, irrigation water, river water, farm soil, playground soil, and dirt on the surface of people’s hands. The results showed that exposure trends were strongly reflected by people’s life style, and that intentional ingestion of drinking water/food, as well as accidental ingestion of water/soil, greatly contributed to their total exposure.
Short biography:
Dr. Hidenori Harada, is an assistant professor of Kyoto University, and since November 2014 has been a visiting professor at Eawag/Sandec. He has been engaged in field-based research on Water, Sanitation and Hygiene (WASH) in developing countries on such topics as faecal microbial exposure analysis, decentralized or semi-centralized sanitation technology, and faecal sludge management.
