Beschreibungen/Notizen

• In general, the history of environmental research is not known very well. Our study contributes to filling this gap by focusing on the history of the methods that were used during the 20th century to study the state of the urban sea area in Helsinki, Finland. From the beginning of the past century, the methodological basis of municipal water pollution studies in Helsinki was broad, involving the use of physical, chemical, hygienic and biological methods. Since 1904, municipal laboratories have overseen and conducted most physico-chemical and bacteriological studies of pollution of urban watercourses, and they have done regular annual sampling since 1947. In the 1920s and 1930s, the municipal laboratories cooperated with the University of Helsinki and, secondarily, with the Helsinki University of Technology in order to develop the skills and manpower that were required in order to conduct pollution studies. Statutory monitoring was initiated in the mid-1960s, and it continues today.
