Article Synopsis
- The study examines tungsten and 14 other heavy metals in a stream affected by treated wastewater from a semiconductor park in Taiwan, where treated effluents contribute roughly 50% of the river's annual discharge.
- Dissolved tungsten levels in the effluents reach 400 μg/L, significantly higher than the global average of <0.1 μg/L, and particulate tungsten concentrations in sediments are also extremely elevated, with enrichment factors three times the average crust composition.
- The estimated annual export of tungsten to the ocean is 23.5 tons, raising concerns similar to levels seen in the unpolluted Yangtze River, emphasizing the need for further research into the biological impacts of this contamination.
