Marine carbonates, precipitating from seawater through inorganic geochemical and biogeochemical processes, are considered to have recorded the signatures reflecting marine environmental conditions during their formation. However, they susceptible post-depositional diagenetic alteration. The redox chemical composition of fluid may be different those overlying seawater. Therefore, assessing wheth...

The multiplicity and wide variety of applications electrical electronic equipment has largely increased with the technological economic progress and, in consequence, amount generated waste (WEEE). Due to inappropriate processing disposal WEEE, different chemical elements compounds, including rare-earth such as Lanthanum (La) have been released environment. Nevertheless, environmental risks resu...
