Tracing anthropogenic Technology Critical Elements using Environmental Forensics : Case studies at Kallholmsfjärden and the Bothnian Bay, northern Sweden
The rapidly changing landscape of today's technology industry has increased the number of electronic products being discarded. Society is always on the hunt for the latest product and newest technological advancement, thereby creating a constant influx of older model products into fast-growing...

The rapidly changing landscape of today's technology industry has increased the number of electronic products being discarded. Society is always on the hunt for the latest product and newest technological advancement, thereby creating a constant influx of older model products into fast-growing waste streams. These products often contain a variety of metals, some of which are in high demand for their importance in technological applications but are in relatively short supply. These technology critical elements (TCE) are often insufficiently researched, and their natural abundance and behavior in environmental systems can be poorly understood or not known. This lack of comprehension creates a difficulty in tracing sources of their dissemination into the environment and an inadequacy in understanding the potential effects on environmental habitats. This thesis is an environmental forensics approach to tracing anthropogenically induced Cd and TCEs in sediments and groundwater in Kallholmsfjärdin, Northern Sweden. This area has been heavily industrialized since the early 1930s by Boliden Mineral AB's Cu-Pb-Zn smelter at Rönnskär.
