Description Boron in the waters of Mandovi Estuary, Goa, India varied with tides and seasons with concentrations decreasing from mouth towards upstream. Higher concentrations of 0.51-5.83 mg kg1 and 0.03-4.42 mg kg-1 respectively were observed during the pre and postmonsoon season as compared to relatively low levels in monsoon (0.01-2.70 mg kg-1) due to increased suspended sediment loads and high dilution resulting from large quantities of freshwater influx. Addition of boron to the extent of 27.74% during the postmonsoon and removal upto 31.30% in the monsoon were observed. In the postmonsoon months, removal of boron to some extent was observed due to phytoplankton. The pH and dissolved oxygen showed a negative correlation with boron whereas chlorinity and alkalinity gave positive correlations with a linear variation. Though the overall behavioural pattern of boron indicated non-conservative nature, it showed a quasi-conservative character during premonsoon and a non-conservative during rest of the seasons
