Short summary
Salt weathering is influenced by factors such as salt type, concentration, moisture, temperature, and material properties. Environmental conditions and microbial activity can further impact this process. Experimental studies on bacteria in porous systems face challenges from environmental chemistry, detector components, and contamination. Adapting rules and procedures is essential for accurately assessing bacterial activities in salt-bearing porous systems.
