Abstract
- In this work data of salinity, temperature, suspended particulate matter (SPM), chlorophyll-a, and phytoplankton concentration in the Gibraltar Strait coast, in the confluence of the Mediterranean Sean and the Atlantic Ocean, were analyzed together with <superscript>210</superscript>Po, <superscript>40</superscript>K, <superscript>210</superscript>Pb and <superscript>234</superscript>Th activity concentration in different types of bivalve molluscs at the same time-period. The physicochemical parameters were evaluated using the Copernicus Marine Environment Monitoring Service (CMEMS) products based on satellite observations. A multivariate statistical analysis, including contrasted natural radioactivity contents, allowed the discrimination of bivalve molluscs from Atlantic and Mediterranean coasts. Additionally, a cluster analysis determined a highly significant negative correlation <superscript>210</superscript>Po concentration in molluscs and phytoplankton concentration suggesting that phytoplankton concentration in the water column is a determinant factor to regulate <superscript>210</superscript>Po concentration in those animals. These results introduce a useful tool to calculate the radiological doses in seafood from chlorophyll satellite image. • First time that physicochemical parameters based on satellite observations were analyzed with activity concentration. • A significant negative correlation was shown between <superscript>210</superscript>Po concentration in molluscs and phytoplankton concentration. • A multivariate statistical analysis allowed the discrimination of bivalve molluscs from Atlantic and Mediterranean coasts. • Radiological doses in seafood were obtained through chlorophyll satellite image.
