b>Background: Risky behaviors often place young people young people in problematic situations. The aim of this study is to examine the factors that influence risky decision making in a group of young people studied. Methods: Between 1 April and 30 July 2022 and through a remote questionnaire, the cross-sectional study included 204 young people, 26....

PAHs (polycyclic aromatic hydrocarbons) are a type of organic compounds arising from the incomplete combustion of natural materials. PAHs are harmful organic pollutants and are omnipresent in the environment. It is well known that some hydrocarbons are highly carcinogenic, and for this reason, they become of great interest recently. Anthropogenic a...

The agricultural sector, which is a predominant part of the economy, is facing climate change alternating with water scarcity. The impacts of climate change are presented by extreme and frequent meteorological events that threaten crops and its evolution. Several studies have shown that climate change would have a negative impact on climatic variab...

Food poisoning due to the consumption of bivalves has been known for a very long time. Indeed, some toxic microalgal species proliferate excessively under certain climatic and hydrological conditions and cause a harmful algae bloom. However, these species produce phycotoxins that accumulate in the different tissues of shellfish.Transferred to human...

Contamination of food by metal residues remains in the forefront of food security concerns worldwide. The presence of these trace elements in fruits, vegetables, cereals, meats, fish, seafood, shellfish, eggs and milk is the subject of several monitoring plans.Living beings can be contaminated by these trace metals through their presence in the env...

Water turbidity is a key index used to evaluate coastal water quality conditions. To determine the turbidity in large areas, remote sensing technologies have the potential to provide a cost-effective alternative to experimental methods that require extensive time for field data collection and laboratory analysis. This research focuses on the develo...

Understanding the relationship between the spatial distribution of forest vegetation and influencing factors provides valuable information to decision-makers in land planning, for the sustainable development of forests and efficient monitoring of environmental and ecological issues. This paper aims to understand the effect of topographic factors an...

A palynological study of carbonate mounds of Atlantic and Mediterranean Moroccan margins was conducted on sediment boxcores MD13-3441, MD13-3456, MD13-3461, MD13-3465, MD13-3468 collected during the oceanographic cruise MD 194/Eurofleet - GATEWAY, which took place on June 2013. The organic remaining revealed a dominance of dinoflagellate cysts over...

Abstract: An intense bloom of Karenia sp. was reported in the Oualidia lagoon, part of Atlantic Moroccan coast. The highest concentrations are 1.04 × 107 cells/L, and have been noted at the park station 7. High nutrient concentrations have been observed, and PO4 was the highest value (av. 396.18 μg/L) recorded at Parc 7. This massive proliferation...

L’étude qualitative et quantitative des dinoflagellés (kystes et formes végétatives) a été réalisée sur des échantillons de sédiment de surface et d’eau, prélevés au cours du printemps 2013 dans les lagunes de Oualidia et de Sidi moussa. En plus de définir le palynofaciès et de préciser les pourcentages et l’évolution spatiale de ses composantes, c...

Cette étude palynologique, fondée sur l’analyse qualitative et quantitative de kystes de dinoflagellés, vise à comparer les conditions environnementales entre deux lagunes situées sur le littoral atlantique marocain (le complexe lagunaire Oualidia / Sidi Moussa) et une troisième située sur la côte sud méditerranéenne marocaine (la lagune de Nador)....

Etant le premier maillon de la chaine trophique, le phytoplancton, qui désigne l’ensemble des organismes marins qui vivent en suspension dans l’eau, joue un rôle prépondérant pour le fonctionnement des écosystèmes marins. Certaines espèces phytoplanctoniques peuvent proliférer et entraîner des efflorescences formant des eaux colorées (rouge, brun,...

This palynological study, based mainly on the qualitative and quantitative analysis of dinoflagellate cysts, aims to compare the environmental conditions between two lagoons located on the Moroccan Atlantic coast (the Oualidia / Sidi Moussa lagoon complex) and a third one on the Moroccan southern Mediterranean coast (Nador lagoon). The Atlantic lag...

From September 2012 to July 2013 the phytoplankton community was studied from five sampling stations located along the longitudinal axis of the Sidi Moussa lagoon, situatied in the atlantic Moroccan coast. Seasonal and spatial patterns of distribution in relation to some hydrological parameters (temperature, salinity and nutrients) are also reporte...

The climatic changes impact the composition and specific structure of the phytoplankton population since its development depends directly on biotic and abiotic environmental conditions. Because of their ability to encystement when conditions are unfavorable, Dinoflagellates are extraordinary indicators of environment change, there are also consider...
