Community Based Environmental Research in Indonesia

Researcher:  Dr Evan Edinger

Community-based environmental research in Indonesia focuses on the environmental impacts of two mines.

The first study examines the impacts of a nickel mine and smelter in Sorowako, South Sulawesi on air quality, water quality, and human health.  The town of Sorowako is on the shores of Lake Matano, one of Indonesias great lakes, with unique limnology and an endemic fish fauna.

The second project examines heavy metal contamination from gold mining in North Sulawesi.  An industrial mine dumps arsenic-, antimony- and mercury-rich tailings into the ocean, while small-scale mining releases elemental mercury to the air, rivers, and ultimately nearshore marine areas.  Metal concentrations and forms are studied in marine sediments and in coral skeletons.
