Mobility of metals in water, mine wastes, and stream sediments around the abandoned Alaşehir mercury mine was investigated to evaluate the environmental effects around the area. Mine waters are dominantly acidic with pH values of 2.55 in arid season and 2.70 in wet season and are sulfate rich.
The Hg accumulation in soils is about 800,000 tonnes in mineral soils and 150,000 tonnes in organic soils. In the European Union, the mercury emissions are around 80 tonnes per year (<5% of the total global ones) with the coal sector contributing most of it (Xu et al., 2015). Mercury compounds are toxic to humans and animals.
