“…Lichens present a very important model of symbiotic organisms when associating a mushroom called mycobiont and green algae and/or cyanobacteria called photobionts (Nash III, 2008). They are used in the bio indication of air quality (Bosch-Roig, Barca, Crisci, & Lalli, 2013;Kar, Samal, Maity, & Santra, 2014;Loppi, 2014;Kuldeep & Bhattacharya, 2015;Pescott et al, 2015;Sulaiman, Fuzy, Muis, & Ismail, 2018;Benítez et al, 2019;Mohamed, Mohamed, & Abdelhay, 2020;Quijano-Abril, Ramirez-Ospina, Domínguez-Rave, & Londoño-Valencia, 2021). Lichens are devoid of roots, and mineral nutrition takes place from atmospheric inputs (Garty et al, 2008).…”

The assessment of the air quality is a major concern to the current time. The monitoring and maintenance of air quality necessarily pass by detecting and estimating the overall air pollution. The use of lichens must be an assessmenttool to be studied. In our work we were interested about the toxicity of lead on the various parameters of stress in the lichen Xanthoria parietina. For this purpose, lichen thalli have been incubated at lead concentrations of 0, 0.5, 1.0, 5.0 and 10.0 mM, for time scale of 0, 24, 48 and 96 hours. The obtained results showed that lead has an action on the various studied parameters, and the intensity of oxidative stress observed in lichens thalli depends on the concentration, and time of exposure. Lead induced a decrease in chlorophyll and protein contents, and an increase in the contents of catalase, hydrogen peroxide and reduced glutathione. Furthermore, the results also showed that high concentrations of lead caused total destruction of reduced glutathione.

Due to the COVID-19 pandemic, most of the marine activities and all the anthropogenic activities along the coast have been shut off for several months. The total suspended matter (TSM) was analyzed before and during COVID-19 lockdown in the coast of Morocco. Therefore, the aim of this study was to assess all the changes reflected through the coast in April of 2018, 2019, 2020 and 2021. In the absence of the ground observations during this period, the remote sensing data was used in this study. The results showed a gradual reduction in TSM concentration, indicating a positive improvement during the lockdown period. The TSM concentrations during this period decreased by 40.59% on average compared with the pre-lockdown period. Further, the turbidity in the water has reduced at each stretch of the rivers. Remote sensing is a powerful tools for analyzing turbidity over the whole littoral areas, even in the absence of field observations. The ongoing pandemic shows that an ocean with cleaner water is possible. These findings provide a general reference on the state of the Moroccan coast that could contribute to improve policy and future monitoring program.
