Analysis with Outlier Releases Removed Figure 36 shows the sources of releases from the last seven years with the single large events removed. In this dataset, a significant downward trend in the mass of accidental chemical releases is apparent since 2010. The total volume released in 2010 was 499 tonnes, compared to 87 tonnes in 2016, an 82 per cent decrease. The most significant sources of chemical releases remain the same.
