The impact of the fishing industry was evaluated in the coastal marine system of Puerto Malabrigo; Rázuri district, Ascope county; Region LA Libertad from May to December 2003. Four sampling stations were settled down, 1: 500 meters at south of the jetty, 2: Betwen snub and borders in front of SIPESA plant; 3: Betwen snub and borders in front of HAYDUCK SAC plant, 4: At one Km at north of the station 3. Samples of surface water and bottom, as well as of silts, were took and they analyzed following the methodology suggested in the annexes 1, 2 and 3 of the Ministerial Resolution Nº. 0032002-PE (Protocol for the drain pursuit and receiving marine body of 2002-04-13). Total and fecal Coliforms x 100 ml; were determined by the Normalized Methods of the Analysis of Drinkable and Residual Waters 9215 A, 9221 A, 9221 B, 9221 C described by APHA; AWWA and WPCF (1989). It was concluded that: 1....

The objective of the research was to determine the economic valuation of the ecosystem services of provision and landscape from the Historical Sanctuary “Bosque de Pómac” and to formulate retribution mechanisms, the methodology of the contingent valuation expressed in the availability to pay was used. 8-item surveys were applied to 374 inhabitants from 14 villages in the buffer zone and 1-item surveys were used to 659 regional, national and foreign visitors of the SHBP, both validated with the Cronbach’s Alfa. Filed work was carried out from June 3rd to November 30th, 2017, central tendency measures were later used and the availability to pay. It was concluded that: 1. The inhabitants from the buffer zone of SHBP expressed their willingness to pay on average S /. 20.98 for a quintal of carob dried fruit; S /.7.45 for a quintal of sapote dried fruit, S /. 22.37 for the fallen branc...

To measure the efficiency of microbial consortia formed by Nitrobacter sp. Nitrosomonas sp. Bacillus subtilis,Bacillus licheniformes, Saccharomices cereviceae, Saccharomyces fragilis in the treatment of urban wastewater,variables defined in DS 003-2010-MINAM were measured. The Nitrobacter plus ® brand probiotic suspensionwas diluted in deionized water, then molasses and urea were added constantly stirring for 96 hours,subsequently added to wastewater samples from the PTAR of the city of Lambayeque and Santa Rosa(Chiclayo), with the experimental design with increasing stimulus: Control, 0 ml; Dilution 1: 24 mL / L,Dilution 2: 48 mL / L, Dilution 3: 72 mL / L, Dilution 4: 96 mL / L in 20 L buckets. It was concluded that themost noticeable effect on the wastewater of the PTAR of the city of Lambayeque was verified in the decrease ofBOD5 up to 48.2 mg / L and the population of thermotoleran...

To measure the biodiversity of flora in the lower basin of the Reque river, 8 perpendicular transects were traced at distances of 10 x 250 m on each side of the Reque river bed from 20 to 30 October 2020. In them, flora species were identified; The number of specimens per species and transect were recorded in a Microsoft 2013 Excel spreadsheet, saved with the csv extension delimited by commas. The Species Diversity and Richtnes and PAST software were used to determine Alpha and Beta Biodiversity Indices. It was concluded that the most abundant plant families were Fabaceae with species of Prosopis sp (algarrobo); Acacia huarango (huarango), Crotolaria incana; Cajanus cajan (stick beans) and Inga Fewelei (guava) and Saccharum officinarum (sugarcane Distichlis spicata (salty grass), Zea mays (corn) and Sorghun halepensis (sorghum) of the Poaceae family. The Shannon-Wiener index varied from ...

The efficiency of the 600 liters standard biodigester was evaluated, as well as the addition of 1 liter, 10 liters and 100 liters of microbial consortiums named probiotics on 13 samples of rural domestic wastewater treated in biodigesters in the Santeño Annex belonging to the El Carmen sector district of Tumán. After the activation of the probiotics, certain concentrations of the microorganisms were added. the microbiological was determined at the beginning of the experiment and after 24, 48 and 96 hours. In the Microbiological quality the concentrations of Thermotolerant Coliforms by the NMP / 100mL technique were determined. It was concluded that 1. The standard biodigester does not perform an efficient treatment in the microbiological quality of rural domestic wastewater, because the MPN value ≥ 2400 / 100mL of the thermotolerant coliforms are above the maximum permissible limits ...
