Concentration of heavy metals in Mirusha and Stanishor rivers of Gjilan municipality and their impact on pollution of the Morava river, Kosovo

Journal of the Turkish Chemical Society, Section A: Chemistry, 2019
Pollution with the heavy metals of Kosovo's rivers has been and continues to be a serious concern not only for the population, but also for responsible institutions that deal with environmental protection in our country. Based on this fact and our doubts

Development of an analytical method for accurate and precise determination of rare earth element concentrations in geological materials using an MC-ICP-MS and group separation

Frontiers in Chemistry, 2023
The concentration of rare earth elements (REEs) in geological materials including SLRS-6 (natural water certified reference material) and JB1b, JA1, and JG2 (Standard Rock Materials of Geological Survey of Japan) can be used as a tracer to characterize ...

Microbes from Brine Systems with Fluctuating Salinity Can Thrive under Simulated Martian Chemical Conditions

Life, 2021
The waters that were present on early Mars may have been habitable. Characterising environments analogous to these waters and investigating the viability of their microbes under simulated martian chemical conditions is key to developing hypotheses on ...

Manganese content records seasonal upwelling in Lake Tanganyika mussels [PDF]

Biogeosciences, 2007
Biogenic productivity of Lake Tanganyika is highly dependent on seasonal upwellings of cold, oxygen-depleted, nutrient-rich deep waters. We investigated the shell of freshwater bivalve Pleiodon spekii as a geochemical archive of these periodic ...

Distribution of Cromium (Cr) in the Bottom Substrate around Kebintik and Batu Belubang Coastal Waters, Bangka Island [PDF]

BIO Web of Conferences
Within the next five years, the post-tin mining coastal waters of Kebintik and Batu Belubang in Central Bangka are expected to run out. Habitats for commercially significant and community-consumed benthos (bivalve class, such as Anadara granosa and ...
