The objective was to know the influence of the bioadsorption of opuntia ficus –indica in the acid drainage of Minera Pampamali, 2022; the research was applied, descriptive-correlational level, descriptive-non-experimental method, cross-sectional descriptive design, population comprised of all the Pampamali mine entrances, 8 liters of acid water sample were taken from the main mine entrance; A sample of the opuntia ficus –indica plant was also obtained by simple random sampling; which were transferred to the EPIM-UNH laboratory to submit them to the experimental analysis processes; obtaining as results with the support of the atomic absorption spectrophotometer brand TERMOCIENTIFIC ICE 3000 SERIES AA SPECTROMETER; in 50 ml of acidic water, a concentration of 0.1004 mg/L; then, intervening the opuntia ficus –indica; for a proportion of 100ml of acid water acting with 30g of bioadsorb...

The objective was to determine the concentration of heavy metals in sediments and troutin the Opamayo and Sicrarivers; the problem is, harmful metallic existence in hydric life, the methodology was applied, developed with specialists in mining, chemistry, environment; In the field, samples were collected in aquatic channels, in the laboratory with sieving techniques, analytical balance; and THERMOCIENTIFIC ISO 3000 SERIES Atomic Absorption Spectrophotometer; The following sediments resulted: Lead (Pb = 0.07 mg / L), arsenic (As =0,04 mg/L), cadmium (Cd = 0,013 mg/L), chromium (Cr = 0,05 mg/L); being below the maximum permitted level Supreme Decree D.S.N° 0015-2015-MINAM. The heavy metal concentrations in trout in the Opamayo River exceed those of the Sicra River: In arsenic 0.804 mg/kg, cadmium in 0,086 mg / kg, chromium in 0,227 mg / kg and lead in 1,659 mg / kg concentration; therefor...
