As 80% CI (i.e., lower and upper bounds are 10% and 90% percentiles, respectively).
†
The authors of the study did not include an estimate of the uncertainty range. We assume the uncertainty range of this source is a factor of 2 larger than large-scale gold mining.
‡
The uncertainty ranges are only available for 2005 to 2010. We adopted the 2005 value for 1990 and 2000 because most of the emission control started in the year 2005.
§
We assume the same uncertainty range of emissions as calculated by Streets et al. (1).
