“The central goal of my research is to develop methods for identifying sources of contamination in water resources and to help ensure access to safe water for everyone. Specific topics include the efficiency of treatment methods for wastewater, sewage sludge, and manure as part of circular economy solutions,” says Pitkänen.
Pitkänen currently devotes most of her efforts to wastewater monitoring for coronavirus and other infectious diseases. Pitkänen, together with
The changing climate is another factor posing new challenges to environmental health. For example, summer heatwaves raise surface water temperatures, increasing the likelihood of harmful microbial growth. As rainfall increases, runoff from livestock farms and urban areas will increase the microbial load in surface waters.
The traditional focus of environmental health, the impact of environmental factors on human health, can be complemented by covering animal health as well.
“Humans and animals share the same pathogens and a changing habitat. The One Health approach, built on this foundation, is an excellent framework for my research. As a member of the
Tarja Pitkänen graduated from the University of Eastern Finland with a major in environmental science. After completing her doctoral project on Campylobacter as the cause of drinking water borne outbreaks, she worked as a research scholar at the US Environmental Protection Agency. From there, she returned to the Kuopio unit of the Finnish Institute for Health and Welfare (THL) to serve as an expert in environmental health, specifically aquatic microbiology. In her new professorship, Pitkänen will split her time between the University of Helsinki and THL, which recently joined the HOH network.
