La contaminación acústica representa un importante problema para el mundo moderno, donde la exposición al ruido está afectando considerablemente la salud de los habitantes (enfermedades cardiovasculares y trastornos del sueño). Motivo por cual se evaluó el ruido en los exteriores del mercado mayorista pesquero COMPHILL por 10 días de 2 am a 12 pm en 4 puntos, los cuales se seleccionaron con una encuesta aplicada a los pobladores aledaños al mercado. Los resultados obtenidos de los niveles de ruido en el día de menor incidencia fueron de 56.1 dB (2 am), 55.8 dB (3 am), 56.3 dB (4 am), 56.5 dB (5 am), 66.4 dB (6 am), 69.1 dB (7 am), 68.5 dB (8 am), 67.9 dB (9 am), 63.1 dB (10 am), 66.3 dB (11 am) y 60.2 dB (12 pm), y en el de mayor incidencia: 55.9 dB (2 am), 56.1 dB (3 am), 56.1 dB (4 am), 59.3 dB (5 am), 68.2 dB (6 am), 70.4 dB (7 am), 69.7 dB (8 am), 71.1 dB (9 am), 74.5 dB (10...

In this study we evaluated the ergonomic risks in workers' health Fish Farming Center. The sample universe consisted of the 15 workers of Motil Fish Farming Center, Department of La Libertad, Peru. Samples were taken every month. The methods used to assess ergonomic ergonomic risk were: Job Strain Index (JSI), Rapid Entire Body Assessment (REBA) and Oako Working Analysis System (OWAS). The Results demonstrated by the methods of JSI and REBA that selection and maintenance activities are generating greater risks, and, according to the method OWAS, the activity that generates higher risks is that of selection, followed by selection activities of gravid females and maintenance. It was concluded that the activities that need immediate corrective measures are the selection and maintenance.

El crecimiento poblacional mundial permite desarrollar nuevas actividades, como la Acuicultura y con ello la problemática de los desechos que genera. La producción y transformación de la trucha arcoíris, genera desechos como: vísceras, aletas, piel, cabeza, etc., con macro y micronutrientes importantes; que, sin tratamiento adecuado, desencadena problemas ambientales. Además, en la actividad agroindustrial, concentrada en el cultivo de caña de azúcar, es conocida por su alta demanda de nutrientes del suelo, debido al uso de fertilizantes químicos inorgánicos. El objetivo de la investigación fue, la elaboración de biofertilizante de desechos orgánicos de trucha arcoíris para la mejora del cultivo de caña de azúcar, Santiago de Cao. Metodología aplicada experimental, donde se usará el biofertilizante obtenido como estimulante en 03 concentraciones y 01 testigo de fertiliz...
