“…2). The bioavailability of OCPs has been correlated with the yearly seasons, their concentrations have been reported to be higher in the seasons after the rainy season or in the dry season [103,104]. In this study, the same characteristics are presented when the highest concentrations occur in the spring after the intensive agriculture irrigation season in the zone [35], or after the rainy season due to atmospheric deposition and e uent increase on NAV [105],…”

The Navachiste complex (NAV) is impacted by neighbored human activities and is located in the southwestern coastal zone of the Gulf of California. The study determines the trace metal (TM) and organochlorine pesticides (OCP) health risk content in the edible tissue of Sphoeroides spp. from NAV. The daily intakes (EDI), target hazard quotient (THQ), hazard index (HI), and carcinogenic and non-carcinogenic risks were calculated. Twenty OCP and seven TM were detected with the following trend for TM: Zn > Fe > Pb > Ni > Mn > Cu > Cd. Cd, Cu, Fe, Mn, Pb, and Zn were above MRLs. The γ‒Chlordane was the most frequent OCP. The highest average concentration was for α‒HCH, followed by γ‒chlordane. With the high ratios of γ‒HCH, p, p'‒ DDD and p, p'‒DDD, and the absence of p, p'‒ DDT, the higher ratios for dieldrin and endrin than for aldrin, α‒ chlordane, γ‒chlordane, heptachlor, and heptachlor epoxide indicates historical contamination. In contrast, the residual products of methoxychlor, endosulfan, and its isomers indicate endosulfan's recent use. The TM EDI, THQ > 1 (at 120 g day-1), and the ILCR (> 1 × 10-6) were above minimum levels, showing a high-risk potential for cancer development in the long term.

“…Despite their beneficial effects, pesticides have a harmful impact on humans and on the quality of the environment and foods [21,22]. Organophosphate insecticides are among the most widely used pesticides in Tunisia and the rate of poisoning by these pesticides represents 11% of all acute poisonings according to the Toxicology Reference Center in Tunis (center of urgent medical assistance and resuscitation CAMUR) [23].…”

In the present study, a battery of biological tests undertaken in vitro and in vivo was used to evaluate the toxic potential of an organophosphorus insecticide, namely Fenitrothion. The cytotoxic effect of pesticide was evaluated with the MTT assay against two human cancer cell lines: Hep-2 and MDA-MB-231. Genotoxicity was also studied using the bacterial VITOTOX® assay. The estrogenic effect was tested using the recombinant yeasts (YES) assay. Likewise, bioluminescence assays using V. fischeri and D. magna immobilization were performed. The results showed that Fenitrothion exhibits a variable cytotoxic effect depending on the dose as well as the studied cell lines, and no genotoxicity was observed in the tested sample. However, an estrogenic effect was recorded when investigating Fenitrothion using the recombinant yeasts (YES) assay. Analogously, acute toxicity was observed for both organisms and at all tested concentrations of Fenitrothion. Overall, these results underline the crucial importance of in vitro and in vivo bioassays in monitoring toxicity of pesticides.

“…Several studies have focused on the species of P. oceanica (L.) Delile as being an excellent bioindicator for evaluating the quality of the environment of coastal stations (Ferrat et al, 2003;Lafabrie et al, 2007;Serrano et al, 2011;Serrano et al, 2012). Most of these latest studies have shown that P. oceanica has the capacity to sequester chemical pollutants from the marine environment and accumulate them in its perennial tissues for several decades (Jebara et al, 2021b). Therefore, P. oceanica is a re ector of the ecological state of coastal ecosystems and its storage capacity of geochemical records of the marine environment could be used as an alternative to trace the history of contamination of coastal ecosystems (Tovar-Sánchez et al, 2010).…”

Faced with the significant disturbances, mainly of anthropogenic origin, which affect the Mediterranean coastal ecosystem, it is necessary to set up rapid diagnostic tools for these disturbances. Posidonia oceanica, which is one of the pillars of this ecosystem, has often been used to assess the state of health of the Mediterranean coastal environment. Despite environmental changes, this plant can accumulate reserves which allow it, during relatively long periods, to keep a stationary phenology. It may also represent important mechanisms for the dissemination of antibiotic resistance genes among pathogenic bacterial populations. The present study aims to determine the multi-drug resistance patterns among isolated and identified epi-endophytic bacterial strains in Posidonia oceanica seagrass collected from Mahdia coastal seawater (Tunisia). 43 isolates were obtained, seven of them were selected and identified. These isolates belonged to the genus Bacillus. Susceptibility patterns of these strains were studied toward commonly used antibiotics in Tunisia. All identified isolates were completely resistant to Aztreonam, Ceftazidime, Trimethoprim, Amoxicillin and Rifampicin.
