英文摘要: The concentration and carbon isotopic ratio (δ13C) of dissolved inorganic carbon (DIC) in natural waters is often altered by microbial activity, even over short durations, which can affect sample preservation. Hence, the influence of these biogenic processes should be limited to properly investigate DIC in natural waters. This study investigates the effectiveness of filtration and exposure to benzalkonium chloride (BAC) and sodium chloride (NaCl) for preserving natural water samples (seawater, groundwater, river, pond, hot spring, and brackish waters) in order to analyze the concentration and δ13C of DIC. We assessed six filter materials with pore sizes of 0.2–5.0 μm. In the waters filtered by polyether sulfone, polyvinylidene fluoride, or cellulose acetate filters, the number of...
