Title: Comparison of concentration values recorded for NMP locations with Annex 1A/OSPARCOM locations
Author: Environment Agency Toxic and Persistent Substances National Centre
Document Type: Monograph
In 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. The 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. OSPAR are Protocols on Methods for the Testing of Chemicals Used in the Offshore Oil Industry.
