ANNOUNCEMENTS
The study looks at the physicochemical parameter values and metal (Fe, Ni. Cu and Zn) concentration values in the Mahanadi estuary (semi-diurnal estuary) and how do these vary with tides, during the study period of 7-21 February 2021. The study looks tries to understand if the presence of metals in water can prove as a threat to human health. The study also tries to establish correlation between various metals themselves and between metals and physicochemical parameters. It was found through various indices (HI, HQ and CDI) that the metal concentration in the water is low as compared to other and it does not have any impact on the adults and children through both dermal and ingestion pathways. Iron was found to occur at significant levels as opposed to other metals. It was also found that except at one of the stations (E1) during low tide, TSM and Turbidity not have any significant positive correlation as expected. It was also found that except for Fe, all the metals were found to have more value at downstream station E2.
Keywords: Heavy metals, metal toxicity, tidal cyclicity and, heavy metals, health impact of metals, and physicochemical parameters.
