Biomedical Waste Management (BMW) Assessment at the RHC Regional Hospital in Tangier, Morocco
Biomedical waste is a real danger to public health and the environment. The quantity of this waste, mainly from hospitals, is constantly increasing, leading to various forms of pollution. This is a cross-sectional, observational study that took place in 2017. A questionnaire was submitted to nurses, doctors and those responsible for hospital hygiene and the operation of waste incinerators to assess the mechanisms and knowledge of medical staff in terms of biomedical waste management. It was confirmed that the hospital wastes are still poorly managed due to the absence of a plan or program for MPSD in all the structures studied, which attests to the non-application of the regulations in force and an inadequate internal management system in most laboratories. Due to the non-availability of health technicians and the lack of material resources in quality and quantity, a staff that is poorly informed about the regulations that apply to BMW, and a poorly recognized and disrespected BMW process that breaks even the clearest instructions regarding incineration and landfill disposal. It has become very urgent to adopt new strategies to be planned for an adequate training to be included for better medical waste management
Impact des activitĂ©s humaines sur la dĂ©gradation de la qualitĂ© des sĂ©diments de lâestuaire de Loukkos (Maroc)
The spatial and temporal variation of 6 trace metals levels (Fe, Zn, Cu, Cr, Pb and Cd) were studied in the sediments of the Loukkos river estuary in relation with various human activities of industrial, agricultural and domestic origin.The results obtained show that level of the station where the waste is discharged wastewater from the Larache city; there is a significant change in the values of principal elements (Cr and Pb). Indeed, the metal content of the sediments of these values reach particularly high near the main upstream (high agricultural activity) and downstream (domestic wastewater of the city and traffic) from the estuary. Nowadays, the limit for Cr and Pb exceeded the standard of the Domestic network Observation. This has confirmed by the index of contamination, the analysis of variance and the Principal Component Analysis practised.Les variations spatio-temporelles des teneurs en mĂ©taux lourds : le fer (Fe), le zinc (Zn), le cuivre (Cu), le chrome (Cr), le plomb (Pb) et le cadmium (Cd) ont Ă©tĂ© Ă©tudiĂ©es au niveau des sĂ©diments de lâestuaire du bas Loukkos en relation avec les diverses activitĂ©s humaines quâelles soient dâorigine industrielle, agricole ou domestique.Les rĂ©sultats obtenus montrent quâau niveau de la station oĂč se dĂ©versent les rejets des eaux usĂ©es de la ville de Larache, on assiste Ă une modification importante dans les valeurs des principaux Ă©lĂ©ments (Cr et Pb). En effet, les teneurs mĂ©talliques des sĂ©diments de ces Ă©lĂ©ments atteignent des valeurs particuliĂšrement Ă©levĂ©es Ă trois niveaux : au voisinage du collecteur principal, en amont et en aval de lâestuaire caractĂ©risĂ© respectivement par une forte activitĂ© agricole et un rejet dâeau usĂ©e domestique ainsi quâun trafic routier important. Lâindice de contamination, lâanalyse de variance et lâanalyse en composante principale pratiquĂ©es rĂ©alisĂ©s confirme ceci
Les oiseaux de rivage hivernants (Aves, Charadrii) en Mauritanie: principales espĂšces et zones humides d'importance majeure
The analysis of the distribution wintering waders in Mauritania demonstrated that most of these birds (77 %) are distributed on the Atlantic coast. In fact, this is mainly along this coast that the habitat preferences of this group (sand, mudflats, and near wet grassland) are relatively well represented. Also, the main shorebird populations in Mauritania can be classified into three categories based on their geographical distribution method: Species whose distribution is spread all along the Atlantic coast; these waders seem to favor any latitude. The Mauritanian coast for these species represents continuity between their wintering grounds in Western Europe and those of West Africa. Populations whose distribution is restricted to the northern region of Mauritania; the southern limit of their wintering areas is for these populations. Populations confined mainly in the southern coastal areas the southeastern coast of Mauritania represents, consequently, the northward extension of the main areas of these populations winter in West Africa. From this point of view, the Mauritanian territory constitutes, along through the migration east â Atlantic, a transition zone between Western Europe and West Africa; the northern part of the country plays a role analogous to that of Western Europe, while its southern part is similar to West Africa. The dividing line between the two sectors is represented by the line up of Nouakchott-Nema.L'analyse de la distribution des limicoles hivernants en Mauritanie a montrĂ© que la plupart de ces oiseaux (77 %) sont rĂ©partie sur la cĂŽte Atlantique. En fait, principalement le long de cette cĂŽte que les prĂ©fĂ©rences d'habitat de ce groupe (sable, vasiĂšres et prĂšs de : prairie humide) sont relativement bien reprĂ©sentĂ©s. En outre, les populations d'oiseaux de rivage principal en Mauritanie peuvent ĂȘtre classĂ©es en trois catĂ©gories selon leur mode de distribution gĂ©ographique: espĂšces dont la rĂ©partition s'Ă©tend tout au long de la cĂŽte Atlantique; ces Ă©chassiers semblent privilĂ©gier toutes les latitudes. La cĂŽte Mauritanienne pour ces espĂšces reprĂ©sente la continuitĂ© entre leurs aires d'hivernage en Europe occidentale et celles de l'Afrique de l'Ouest. Les populations dont la distribution est restreintes Ă la rĂ©gion du Nord de la Mauritanie ; la limite Sud de leur aire d'hivernage est pour ces populations. Les populations principalement confinĂ©es dans les rĂ©gions cĂŽtiĂšres du Sud, que la cĂŽte sud-est de la Mauritanie reprĂ©sente, par consĂ©quent, l'extension vers le nord des zones principales de ces populations hivernent en Afrique de l'Ouest. A ce point de vue, le territoire Mauritanien constitue, au long de la migration dans lâEstâ Atlantique, une zone de transition entre l'Europe occidentale et d'Afrique de l'Ouest ; la partie septentrionale du pays joue un rĂŽle analogue Ă celui de l'Europe occidentale, tandis que sa partie mĂ©ridionale est similaire Ă l'Afrique de l'Ouest. La ligne de dĂ©marcation entre les deux secteurs est reprĂ©sentĂ©e par la ligne de transition de Nouakchott Ă Nema.
