Submarine groundwater discharge and associated trace element fluxes from the Coleroon River estuary to south bay, India, has been attempted, because increasing trace elements could result in harmful algal blooms and eutrophication. Trace elements (Al, Cr, Mn, Fe, Ni, Cu, Zn, Sr, Mo, Ba, Pb, Th, and U) in surface water, pore, and groundwater samples were monitored for 10 days in three locations (A, B, and C) by considering tidal fluctuations. The trace elements Al, Cr, Fe, Ni, Zn, Sr, Mo, Pb, Th, and U were greater and found to be influenced by processes, such as fresh groundwater discharge and seawater intrusion. Lower Mn, Cu, and Ba signifies impact due to sediment adsorption, mixing, and elemental exchange during fresh groundwater and seawater mixing. Salinity versus trace element plot infers greater trace element mobility with cumulative salinity influenced by the conformist behavior of freshwater, seawater, and mixing. The calculated submarine groundwater discharge supported dissolved trace elements fluxes were 107,047.8 n mol d⁻¹ m⁻¹ for location A, 183,520.2 n mol d⁻¹ m⁻¹ for location B, and 181,474.4 n mol d⁻¹ m⁻¹ for location C, respectively. Variations in dissolved trace elements fluxes are attributed to variations in pH, free redox environment in the aquifer, adsorption or desorption by sediments, and the environmental cycle of marine organisms.

已经尝试了从Coleroon河口到印度南湾的海底地下水排放和相关的微量元素通量，因为增加的微量元素可能会导致有害的藻华和富营养化。在三个位置（A，B，A，B，C，C，C，C， B和C）考虑潮汐波动。微量元素Al，Cr，Fe，Ni，Zn，Sr，Mo，Pb，Th和U较大，并受新鲜地下水排放和海水入侵等过程的影响。较低的Mn，Cu和Ba表示由于新鲜地下水和海水混合过程中沉积物的吸附，混合和元素交换而产生的影响。盐度与痕量元素图推断出较高的痕量元素迁移率，而累积盐度受淡水，海水和混合液的顺应性行为影响。计算得出的海底地下水排放支持的溶解性微量元素通量为107,047.8 n mol d^-1 米^-1为位置A，183,520.2Ñ摩尔d ^-1 米^-1为位置B，和181,474.4Ñ摩尔d ^-1 米^-1为位置C，分别。溶解的微量元素通量的变化归因于pH值，含水层中的自由氧化还原环境，沉积物的吸附或解吸以及海洋生物的环境周期的变化。
