Evaluation of the qualitative and quantitative of parasitic load and Environmental Risks of Raw Sewage Rejected on the Coast of the City of El Jadida (Morocco)

The main objective of the study was the assessment of the prevalence and the identification of the parasitic load of raw sewage rejected in the seashore of el jadida city. the results showed a variety of parasite species with following average concentrations: hymenolepis nana (4.21 eggs/l),taenia sp. (3.6 eggs/l),moniezia expansa (3.02 eggs/l),ascaris lumbricoides (14.71 eggs/l),capillaria sp. (5.92 eggs/l),trichuris trichiura (4.13 eggs/l),ankylostome sp. (6.01 eggs/l),enterobius vermicularis (1.13 eggs/l) necator americanus (4.3 eggs/l),nematodirus sp. (2.07 eggs/l) and strogyloides sp. (3.63 eggs/l). station s1 and s3 (lower town station and ab station respectively) have the highest level of parasitic load,while,station s2 (station el manar) had a lower level of contamination. the distribution of parasitic helminth eggs varies with the size of the urban and socio-economic level of the urban population connected to each station.
