Evaluation of some physico-chemical and detection of parasites in sediment of Hamrin lake

Abstract EN

Abstract Samples from the clay of the Hamrin lake were taken to detect its composition and the presence of different types of parasites that affect the workers' health with clays.

The concentrations of metal major oxides ranges (48.4-51.2%) for SiO₂, (25.2-28.1%) for Al2O3 and (13.5-14.1%) for Fe2O3, while the concentrations of metal minor oxides were relatively low ranges (1.9-2.5%) for K2O and less than 0.8% for (Cr2O3, CuO, K2O and Na2O.

A non-detectable percentage for MgO, MnO, P2O3, TiO3 and ZnO were obtained.

The most abundant clay in the samples was Kaolinite due to X-ray diffraction patterns, while quartz was the most abundant non-clay mineral.

This research detects cysts and trophozoites from several protozoa parasites in the soil such as (Entamoeba spp., Giardia spp., Cryptosporidium spp., Balantidium spp.; Cyclospora spp), as well as eggs of Ascaris and Ancylostoma spp.
