Re: Comparison of concentration values recorded for NMP locations with Annex 1A/OSPARCOM locations.

IntroductionIn order to assess the quality of the NMP data it was felt necessary to quality control the data by comparing it with other similar data of known quality (o.g. OSPARCOM/A1A). This has been undertaken for all NMP sites throughout England and Wales.

MethodsThe average concentrations of six determinands were calculated from 1991-1993 for all NMP sites. Less than values were taken as zero values. The six determinands were copper, oadmium, mercury (metals), nitrite, orthophosphate (nutrients) and lindane (organic).

The distribution of A1A/OSPARCOM sites were examined for this estuary. Any river discharge (RD) sites where the discharge fed into the estuary, typically upstream of the NMP sites, were included in the analysis as outlined above. Additionally any direct discharge (DD) sites such as sewage treatment works were included where their discharge fed into the estuary.

ResultsThe distribution of all sites included in this analysis for the various NMP sites included are shown on the maps provided. All NMP sites were inohided with the exception of two. The southern sites (Dock head to Selsey Bill were not included due to there being little A1 A/OSPARCOM data available to provide a meaningful comparison. The sites

on the Mersey were not included because of a lack of NMP data. The average concentrations (plus one standard deviation) for the six determinands are represented graphically. Where no data was collected for a specific determinand no graph has been included. Throughout the whole of this project the colour coding for the three different types of location remains consistent. All NMP sites are coloured yellow, all river discharge sites blue and all direct discharge sites in red. For all graphs the locations are plotted approximately in an upstream to downstream direction, reference to the map should be made for their exact location. On graphs where the average concentration is significantly higher than the majority of the data the average value is recorded at the top of the column (note the height of these columns does not correspond to the true value).

Values recorded at the NMP sites should be similar to those recorded for the river discharge sites provided there is no significant input of determinands by direct discharge (e.g. sewage treatment works or industries). Where values at NMP sites are higher than the river discharge sites this may be attributable to direct discharge sites hence their inclusion in this study.

In an ideal comparison similar numbers of samples would be compared from the same years. The nature of the available data meant that this was not always the case, so for some comparisons data from 1991-1993 may be compared with data from 1992. Equally for some sites only one sample is taken per year compared with ten’s from the surrounding sites.
