Iron (Fe) is one of the most common elements in the Earth’s crust. Thus, iron-bearing magnetic minerals are widely present in the environment and originate both from natural and anthropogenic sources. Anthropogenic activities such as traffic, industry, and energy production contribute high quantities of harmful substances and compounds of different particle sizes into the atmosphere which are regarded as a major risk to human health and welfare. Magnetic methods give detailed information of iron-bearing minerals as well as heavy metals, which are incorporated into the surfaces or structures of iron minerals.
Turku Environmental magnetism research group focuses on monitoring of urban and industrial environments. Study emphasis is on ambient air quality, pollutant and pollution source identification as well as their spatial distribution. Research methods consist mostly of various magnetic methods jointly used with SEM-EDX technique and chemical analyses. Also traditional methods are applied, e.g. lichen mapping (SFS-EN 16413). We are specialised in enviromagnetic monitoring by using moss bags (SFS 5794) as active bioaccumulators.
