The information for this indicator was collected by the Food Standards Agency in the UK Total Diet Study (TDS). The TDS is an important part of the UK's surveillance programme for chemicals. It is used to estimate dietary exposures of the general UK population to chemicals in food, identify trends in exposure and to make assessments on the safety and quality of the food supply. The data are collected on a UK basis and are not specific to Wales.The UK TDS involves 119 food categories combined into 20 groups of similar food for analysis. The mean concentrations of chemicals for each food group are used together with data on consumption to estimate dietary exposures for average and high level consumers and for the average UK population.Population exposure estimates take account of changes in both the consumption of the various foods making up the UK diet and in concentrations of the various elements in these foods.

The State of the Environment report presents data on the indicators that monitor progress against the Welsh Government's Environment Strategy. The full set of data, analysis, and notes on all of the indicators are available here through our StatsWales website. On StatsWales, the indicators are presented in a series of online reports which are also linked to data tables which users can then manipulate and/or download.
The statistics come from a range of sources in Wales and across the UK, which are updated at different times and intervals. The StatsWales reports will be updated twice a year in July and December and these updates will be highlighted through a pre-announced headline statistics published on our website. A statistical bulletin showing the status of each indicator will be produced annually in July to provide a snapshot of progess across all the indicators.
The contribution of data and information by organisations which monitor the environment is gratefully acknowledged. Although most indicators are currently measured, some further work is planned to develop the other indicators and in some cases to identify more appropriate indicators, as indicated in the StatsWales reports.
The symbol '-' is used where the data is less than half the final digit shown. This may or may not be a real zero.
Unless otherwise stated, the data in these tables and indicator reports are classed as National Statistics.
