Study of physico-chemical parameters from within PFZ and outside PFZ from the coast of Raigad district at Maharashtra State, India

Abstract

The determination of physicochemical parameters was carried out to examine changes in water parameters in three separate sites of within and outside PFZ from the coasts of Karanja, Murud, and Srivardhan in Raigad district coast Maharashtra, India. From April 2018 to March 2019, several factors such as pH, salinity, dissolved oxygen (DO), temperature, and total hardness (TH) were measured. The minimum and maximum atmospheric and surface water temperatures were 25.0-33.5 (0c), pH 7.1-8.5, salinity 30.0-35.0 (0/00), and dissolved oxygen 4.5-6.2 (ml/l), respectively. The minimum and maximum ranges of total hardness, (6.1-7.4 ml/l) were recorded. Results reveal that water parameters like pH, dissolved oxygen (DO), temperature (atmospheric and surface water), chlorides, calcium, total hardness (TH), of Raigad district coasts shows variations from within and outside PFZ during the study period of April, 2018 to March, 2019.
