Seawater and salt samples (from saltpan) were collected across Goa, India. EDXRF method has been developed for the analysis of V, Cr, Fe, Cd, and Pb in seawater. Zn, Co and As were analyzed by other techniques in seawater. Salt samples were analyzed using EDXRF for all eight target elements. The concentration of Pb, Cr, and V in seawater indicates the significant influence of anthropogenic activity around the study area. This method can be used for the quantification of toxic elements, quality control and regulatory purpose of salt production [ABSTRACT FROM AUTHOR]

The processes of material transport in oceans and their exchange with the land mass are complex and are a concern of interest to many researchers. Seawater and surface sediment samples from Tarapur, Mumbai and Goa from west coast of India were collected and analysed for 226Ra and 228Ra. The activity levels of 226Ra ranged from 19 to 36 Bq/kg while the levels of 228Ra ranged from 25 to 55 Bq/kg in sediments. While the 226Ra and 228Ra activity levels ranged between 1.2–3.7 mBq/L and 3.1–7.1 mBq/L respectively. The activity ratios for the two isotopes were also calculated and were found to range between 0.4 and 2.3. The analyses were carried out using gamma spectrometry. [ABSTRACT FROM AUTHOR]
