First Assessment of Pollution Impact at Essaouira Coast (Morocco) Using Biotic and Abiotic Parameters and the Red Algae Ellisolandia Elongata as Potential Bioindicator of Organic Pollution

Analysis of Macroalgae Diversity in the West Coastal of Pananjung Beach, Pangandaran

“…The optimal salinity for macroalgae growth is 20‰ -32‰ [25], but the salinity of each station reaches 29‰ -35‰ which means that some species are difficult to grow that cause a limited species variability. Macroalgae diversity depends on the flow velocity and pH which has an important role in the diversity of macroalgae [26][27][28]. Optimal current velocity for the spread and growth of macroalgae is 0.20m/s 2 -0.30 m/s 2 [29], but the current speed at West Pananjung Beach, Pangandaran switches between 0.04m/s 2 -0,09m/s 2 which causes limited variability of macroalgae species.…”

The pH also determines macroalgae diversity, the optimal pH for macroalga to growth between 7.5 -8.4 [26], but the pH of the entire station is 7 (normal) that makes the variability of macroalgae is more limited.…”

Assessment of Anthropogenic Pollution by Uv Filters Using Macrophytes as Bioindicators

“…Seaweeds are used for identifying heavy metal pollution in marine environments because they are easy to identify, and also for their availability in some areas (Chakraborty et al, 2014). Seaweeds can be employed to monitor organic pollution because their diversity is strongly impacted by the presence of organic compounds (Sabri et al, 2020). As seaweeds are also the basis of several marine food webs, understanding their pollution by anthropogenic compounds is essential for their environmental importance.…”
