In many areas of Peru, infections by protozoa and intestinal helminths and low levels of hemoglobin coexist. The objective of this research was to determine the relationship of intestinal parasitic infections with hemoglobin levels in children under 10 years of age treated at C.S California Viru (La Libertad, Peru), between January and June 2021, in order to clarify the care priorities. A total of 71 children, of both sexes, participated in this observational, prospective, cross-sectional study. Intestinal parasite infections were determined using the direct technique, with Lugol's and saline solution 0.8%, and hemoglobin levels using the hematocrit test. The results showed Enterobius vermicularis, with 55.6%, as the most relevant species, followed by Giardia lamblia, 33.3%; Hymenolepis nana, 7.4%; Entamoeba coli, 11.1% and Blastocytis hominis, 3.7%; the hematocrit showed that 81.7% of c...

Phytoremediation can be defined as a sustainable technology that is based on the use of plants to reduce in situ the concentration or danger of organic and inorganic contaminants in soil, sediments, water and air. The objective of the present research work was to determine the level of absorption of the roots of Cortaderia rudiuscula Stapf. "cortadera" exposed to lead and iron at concentrations of 0.00 10.0, 20.0 and 30.0 ppm under laboratory conditions. The biological material was collected in areas adjacent to the Chanchacap River (Chanchacap, Agallpampa, Otuzco, La Libertad); the experimental work was carried out in the Environmental Genotoxicity Laboratory of the Academic Department of Biological Sciences of the National University of Trujillo. The experimental unit was the plant C. rudiuscula, exposed to lead and iron; under photo-lighting for 13 days, lead and iron solutions were p...
