- Type
- Sediment
Upstream (S19) and downstream (S20) stations of the river mouth, taken as a comparison far from the Yunfu pyrite mine: 0.77 to 0.79 mg/kg Tl, 206Pb/207Pb from 1.1927 to 1.1978, close to unpolluted basin sediments (1.2012 to 1.2144, Liu et al., 2011) and local rocks (1.1993 to 1.2024) (Liu et al., 2016). Coordinates not given.
