“…In the case of heavy metal assessment, the result showed that boron and manganese were more concentrated during winter season (1.9699 ± 0.9557; 0.9218 ± 0.1451) and less concentrated during monsoon (0.0438 ± 0.0205; 0.0133 ± 0.0019) period at the downstream (Figure 3.1). Similar findings about boron was observed from Tapi, Narmada and Mandovi estuaries [28]; Zuari estuary, Goa [30]. The contamination of boron and manganese was attributed due to additionl of anthropogenic sewage and industrial discharges along the water body.…”

“…The geothermal-hydrothermal waters, water-rock interactions, volcanoes, and saline soils also are the natural sources [29]. The marine geochemists have more interest in boron due to its role in marine alkalinity and its application as isotope systematic and to determine the paleo-pH of oceanic water and paleo-pCO2 of atmosphere as B/Ca ratio; it shows both conservative and non-conservative behavior by the distribution in global estuaries [28]. Present day, natural and mankind both sources contribute to the concentration of boron in aquatic ecosystem.…”

The seasonal investigation about the water quality from Damanganga river estuary on two habitats downstream and upstream was carried out from January to December 2019 containing three major seasons: winter, summer and monsoon. For this monitoring activity total 29 parameters (24 physico-chemical parameters and 5 heavy metals) were analyzed. Multivariate analyses suggested inter dependency among these studied parameters. Water Quality Index is computed based on the major fluctuated and affected parameters. The calculated values of WQI for all three seasons ranged from 122.84 to 173.82 which suggested poor water quality of the water body. WQI values of the investigation area proposed that the estuarine water quality is deteriorated due to high value of presented heavy metals (Aluminum, Iron, Manganese, Boron and Zinc), Chloride, Ammonium and Sulfate in water sample. In this case, the downstream station is having accessional pollutant contaminations while the upstream station is having diminutive pollutant contaminants. Temporally, the dominant frailty found during the winter followed by summer and monsoon. This study field exhibited poor quality of water; the reason behind this might be the impressive surrounding industrial zone as well as other anthropogenic activities. There is quite normal probability distribution expressed by the represented water quality data at the both habitats. The Bray-Curtis cluster analysis shows different percentage similarity level between the water quality parameters.

“…The remaining B, used in detergents, fertilizers, insecticides, fire retardants, and other short‐lived products, adds 0.2 to 0.5 Tg B/yr to the surface hydrogeochemical cycle, where much of it is carried to the sea by rivers. Evidence for increasing anthropogenic contamination from domestic wastewater and agriculture activities in river has been reported for the Seine River in France [ Chetelat and Gaillardet , ], western coast of India [ Singh et al ., ], the Jordan River [ Farber et al ., ], Taiwan [ Liu et al ., ], and UK [ Neal et al ., ], which consistent with the overall increase of anthropogenic loads of major salts in the world's rivers [ Meybeck , , ]. The boron isotope composition of boron ores is typically low ( δ 11 B ~0‰) reflecting the coordination of the borate minerals (i.e., the ratio of trigonal to tetrahedral species) [ Oi et al ., ], and its flux to the hydrosphere is expected to be associated with a low δ 11 B signature.…”

This paper presents a revised and updated synthesis of the biogeochemical cycle of boron at the Earth's surface, where the largest fluxes are associated with the injection of sea‐salt aerosols to the atmosphere (1.44 Tg B/yr), production and combustion of fossil fuels (1.2 Tg B/yr), atmospheric deposition (3.48 Tg B/yr), the mining of B ores (1.1 Tg B/yr), and the transport of dissolved and suspended matter in rivers (0.80 Tg B/yr). The new estimates show that anthropogenic mobilization of B from the continental crust exceeds the naturally occurring processes, resulting in substantial fluxes to the ocean and the hydrosphere. The anthropogenic component contributes 81% of the flux in rivers. The mean residence time for B in seawater supports the use of δ11B in marine carbonates as an index of changes in the pH of seawater over time periods of > 1 Ma.
