Managing exposure to chemicals

Figure 17 shows the proportion of indicator components for which ‘Managing exposure to chemicals is the primary goal that have been assigned to each assessment category, with the exact number of indicator components shown as a label on the bars.

J5 (Prevent harmful chemicals from being recycled) is still in development and H4 (Exposure of wildlife to chemicals in the environment in England) does not currently present information as the time series needed for applying the assessment method. H3a (emissions of mercury to air land and water in England) does not yet have a sufficiently long time series for assessment of trend. H3b (emissions of persistent organic pollutants to air land and water in England) could be assessed.

All of the pollutants measured by H3b showed an improvement over the medium and long term. However, emissions of hexachlorobenzene increased over the short term and polychlorinated naphthalenes showed little or no change. The short-term time period covered the most recent 5 years for which an assessment can be made (2013 to 2018 for H3b).
