In the present investigation, cadmium concentrations in seafood were determined and compared with the maximum levels of Commission of the European Union in its Regulation (EC) Nº 1881/2006 and amending Regulation (EU) No 488/2014. Samples were collected from the fish market of Villa Maria del Triunfo. Analyses were performed by atomic absorption spectrophotometry. The results were: in fish (horse mackerel: Trachurus picturatus murphyi) the average cadmium concentrations was 0,35 mg/kg fresh weight, well above the allowable value which is 0,05 mg/kg fresh weight. In crustaceans (prawns: Litopenaeus vannamei) the average was 0,42 mg/kg fresh weight, being below the maximum allowed limit which is 0,50 mg/kg fresh weight. The ceiling in bivalve molluscs is 1,00 mg/kg fresh weight and different concentrations were found in different species and in white shells (Semele sp) and scallops (Argop...

En la presente investigación se determinaron las concentraciones de cadmio en alimentos marinos, y se compararon con los contenidos máximos según el Reglamento (CE) Nº 1881/2006 y modificatoria Reglamento (UE) N° 488/2014 de la Comisión de la Unión Europea. Las muestras fueron recolectadas del Terminal Pesquero de Villa María del Triunfo. Los análisis se realizaron por espectrofotometría de absorción atómica. Los resultados fueron: en pescados (jurel: Trachurus picturatus murphyi) el promedio de las concentraciones de cadmio fue 0,35 mg/kg peso fresco, muy por encima del valor permitido que es 0,05 mg/kg peso fresco. En crustáceos (langostinos: Litopenaeus vannamei) el promedio fue 0,42 mg/kg peso fresco, siendo inferior al límite máximo permitido que es 0,50 mg/kg de peso fresco. El límite máximo en moluscos bivalvos es 1,00 mg/kg peso fresco y se encontraron concentrac...

In Central and Southern Peru, local and teleseismic data allow having insights on the Wadati-Benioff zone (WBZ) geometry. In the region of Northern Perú, only rough estimates of the WBZ geometry have been proposed, and were obtained using teleseismic data due to the reduced number of mb≥4.0-magnitude earthquakes available. The installation of a local seismic network in the NW border of Northern Perú, allowed the recording of a large number of earthquakes with magnitudes ranging from 1.8 to 4.1 ML, and maximum depths of 120 km., distributed over the area where the occurrence of earthquakes with magnitudes > 4.0 is scarce. In a vertical section, oriented N70˚E earthquakes are distributed along a 10° dipping plane from the trench. Landwards from the coastline, the dip angle increases to 28°. These results allow a high resolution definition of the Nazca plate geometry in NW Perú. Foc...

The objective of this study was to evaluate the toxicological risk due to exposure to soils with the presence of lead and cadmium in areas surrounding the Infantas Industrial Park in Los Olivos - Lima (2018). 40 soil samples were taken, 20 samples in the Carabayllo urbanization and 20 samples in the Villa del Norte urbanization. It was obtained that the concentration of Pb and Cd in Urb. Carabayllo had a mean of 66.97 mg / kg and 0.86 mg / kg; for Urb. Villa del Norte it is 51.43 mg / kg and 0.73 mg / kg respectively. The concentrations obtained comply with the Environmental Quality Standard (ECA) of the Ministry of the Environment of Peru. The Exposure Dose (DE) was estimated in the Carabayllo urbanization, for adults, a DEPb = 0.000143 mg / kg / day and DECd = 0.000002 mg / kg / day were obtained; and for children, a DEPb = 0.002494 mg / kg / day and DECd = 0.000032 mg / kg / day.

A study was carried out to determine cadmium in onion (Allium cepa) in districts of Metropolitan Lima. For the execution of the study, 30 samples were collected of which 10 of them are from North Lima (San Martin de Porres, Los Olivos, Independencia, Comas and Puente Piedra), 10 samples from Lima Center (Cercado de Lima, Jesús María, Pueblo Libre, La Victoria and Rímac) and 10 exhibitions in South Lima (Chorrillos, Villa María del Triunfo, Villa el Salvador, San Juan de Miraflores and Surco). 2 random samples were taken per district and the place of origin of the same was inquired. Cadmium quantification was performed by the atomic absorption method - Graphite Furnace at the Chemical Analysis Services Unit - USAQ (Universidad Nacional Mayor de San Marcos). The minimum and maximum cadmium concentration in onion was 0,02 mg / mg and 0,11 mg / kg, respectively; In addition, the average ...

The continue searching for organization’s process improvement for reduce cost and increase efficiency is a big challenge for organizations nowadays. This paper is about to recognize the importance of process improvement focusing in the right human resource allocation. The research predict best optime human resource allocation in the Superintendencia Nacional de Aduanas (SUNAT) in the chemical materials control area using a linear regression machine learning algorithm. This model was validated with recollected data in the SUNAT’s control locations, the results were compared with historical data to determine their efficiency obtained a mean square error 0.434 that is lower comparing to logistic regression and support vector machine algorithm. This research recommend the implementation of this model in all SUNAT’s controls locations in Peru.

The Royal Household is probably the highest institution of the State as a monarchical system. In this sense, it is worth questioning how these organizations have managed communication with their public of interest during a crisis such as the temporary period of pandemic and post-pandemic, where the World Economic Forum states that it is a time of restart where a great social and economic restart is necessary. The main objective of this work is to know the institutional behavior of the British and Spanish Royal Houses through their respective Twitter accounts to determine convergences, synergies, and communicative styles in the digital environment. All this looking for the keys to the strategic management of the relations of both institutions with their citizens. A quantitative methodological design was established, based on content analysis (Kripendorff's alpha coefficient=0.852) on a co...

Heavy metals generate adverse effects on health at different levels, including, for some metals, the carcinogenic effect, which is why the presence of these substances in food for many countries such as Peru, is considered a public health problem. The objective of this study was to evaluate the health risk associated with the consumption of tomato (Solanum lycopersicum) with the presence of heavy metals such as arsenic and lead in metropolitan Lima. Thirty samples of tomato were taken from the main supply points in metropolitan Lima and the region of origin was determined. The samples were analyzed by atomic absorption spectrophotometry at the Centro de Información, Control Toxicológico y Apoyo a la Gestión Ambiental - CICOTOX. The mean concentration of arsenic in tomato was 0,1908mg/kg, this level exceeded the standard defined by Mercosur (0,1mg/kg). Likewise, the mean lead concentra...
