Effects of Dust Practices on Quality of Soil Supporting Coastal Salt Marshes Vegetation in South Sinai, Egypt

Various toxins frequently and negatively affect the salt marsh plants along the southern coast of the Red Sea. This research investigates the impact of ceramic and cement dust pollutants on soil quality in Egypt's Nabq Protected Area, focusing on the dry and dead hypersaline marsh vegetation. Plots in five locations were studied, revealing that soil quality could be effectively monitored using carbon fraction-based tests. Key change indicators included active microbial biomass carbon, metabolic quotient, basal respiration, total soluble salts, and cations. The combination of ceramic and cement dust improved soil quality characteristics. The El-Ghargana locality showed higher values for key soil quality features than the other sites. The study also demonstrated successful mangrove growth in El-Ghargana, with a 60% increase in growth after one year of treatment, suggesting a significant recovery from toxicity caused by industrial pollutants such as ceramic and cement dust.
