Abstract


Parasitic load of rough wastewater in the Kenitra city, (Morocco)


Like the majority of Moroccan cities, Kenitra is confronted with problems concerning the wastewater management and protection of the quality of water resources (Sebou estuary, Maamora wetland and lake Fouarat). Indeed, a great part of wastewater is released into the estuary of Sebou, in the neighborhood of the Saknia popular districts.
In this present work charged to evaluate the parasitic load of rough
wastewater of three collectors of the city in relation to the demographic
and socio-economic profile of the populations connected to these
collectors, our results highlighted a diversity of parasites in the form of
eggs of helminths with following average concentrations: Ascaris sp.
(13,68 eggs/L), Trichuris sp. (3,84 eggs/L), Enterobius vermicularis (0,60 eggs/L), Ankylostome sp. (2,51 eggs/L), Nematodirus sp. (0,88 eggs/L), Hymenolepis nana (1,96 eggs/L), Moniezia expansa (2,46 eggs/L) and Taenia sp. (1,81 eggs/L). The distribution of parasitic eggs of helminths varied according to the size of the urban centres and the socio-economic level of the urban  populations connected to each collector. This study also highlighted the qualitative and quantitative seasonal variations of eggs of helminths in wastewater of the different collectors of the Kenitra city.
