The environmental recovery of coastal ecosystems is an environmental management initiative for consultation among the main actors in the development of a city. This work presents an environmental recovery proposal that includes certain management instruments, aimed at reversing the situation of environmental degradation of the coastal waters of Chancay Bay. Due to the importance of the town of Chancay at the regional level and due to the complexity of its environmental problems, this proposal constitutes an alternative of environmental management that can be taken into account in other coastal areas of our territory.

Concerns about environmental problems have increased considerably in recent times. Interest has been given at all levels of government, non-governmental organizations, scientific and technical groups, etc. due to the interrelation between the natural environment and the anthropic environment that are feasible to create risky contingencies. These are approached from three variables: the agent (nature and / or man), the time (before, during and after the event) and lastly, the effects it produces. From an environmental perspective, the industrialization of fishmeal has a significant impact on the ecosystem in which it operates, also affecting the well-being and health of people. This industry is an activity that generates foreign exchange, is a source of employment and contributes to the development of Peru, taking advantage of a resource that is relatively abundant in the Peruvian marine ...

The pollution of coastal waters of the Bay of Chancay caused by the discharge of industrial and urban runoff, has prompted the present investigation aimed to know the extent of contamination of coastal waters of the Bay of Chancay and Impacts, to propose recovery measures and environmental control. As a result of this investigation, it is known that seawater Chancay Bay presents values ​​that are well above current regulations (Water Act), leading in extreme cases to 0.00 ml / l dissolved oxygen, 120 mg / l BOD5, 0.00 bits / ind. diversity, among others, confirming a high pollution.

The city of Chimbote presents fishing as one of its main activities, which makes it consider one of the ports with the highest fishing production in Peru. Other activities are the steel industry, among others. These productive activities are leading this city to a deterioration of the environment, one of its causes being the application of inadequate technologies and the misuse of space. Ecological-economic zoning is considered as a planning instrument, which aims to promote the harmonious development of a territory. The present work proposes a methodology, which approximates the proposal of hierarchization of environmental variables, modified according to Etter, (1990) and consists of evaluating a certain situation, from studies of landscapes, plant associations, pedological studies and climatic, all of static type, without considering the evolution and the flows that define the structu...

In order to evaluate the copper content in the mollusc existing Enoplochiton Niger Huarmey Bay in the province of Huarmey, department of Ancash, Peru, the concentration (ug / g) of copper in the muscle of the mollusk was determined by the technique atomic absorption spectrophotometry in the laboratory that used CERPER Method: NOM-117-SSA 1-1994. The samples were homogenized and subjected to wet digestion. To collect samples of shellfish was necessary to establish thirteen sampling stations along Huarmey Bay Area. Seven of these stations were located north of Puerto Punta Lobitos six were located to the south. The year 2001 in Puerto Punta Lobitos occurred an accidental spill of copper concentrate into the sea. Analysis of variance was performed to compare the weight data of copper in relation to the size of the mollusk (II size> 40 mm and ≤ 40 mm Size I) and in relation to the dista...

El objetivo de la presente investigación fue determinar el nivel de riesgo originado por lluvias intensas en el casco urbano de Ferreñafe, provincia de Ferreñafe, Departamento de Lambayeque. Aplicando el análisis documental se recolectó información primaria provenientes del Censo Nacional Perú del año 2017. Para este trabajo se empleó la técnica de observación indirecta, la cual, se caracterizó por ser una ficha de registro de datos. En el procesamiento de datos se apoyó en programa Excel y para poder determinar la peligrosidad, vulnerabilidad y el nivel del riesgo se siguió la pautas metodológicas del Manual para la Evaluación de Riesgos originados por Fenómenos Naturales - CENEPRED, 2014. El riesgo encontrado es de nivel muy alto. Se concluyó que ante la probabilidad de lluvias intensas el nivel de riesgo es alto, y el casco urbano de Ferreñafe podría tener fuertes ...

This paper is focused on creation a program to simulate the dynamic behavior of a reactor of tank with constant reaction which initials in English it is CSTR (Continuous Stirred Tank Reactor), and is considered as a complete mixture and, therefore, it is assumed that their properties are uniform throughout the reactor in which the exothermic reaction takes place of the ethyl acetate saponification with sodium hydroxide. In building the software program used MATLAB and Simulink. For the simulation of the saponification reaction are introduced initial concentrations of ethyl acetate and sodium hydroxide, and the constant temperature jacketing system of CSTR reactor. Next, consideration of the user, changes the data set of variables to simulate and observe, through graphs, the concentrations of ethyl acetate, sodium hydroxide, sodium acetate and ethyl alcohol function of time of the process...

The objective was to identify the environmental impacts generated by the Drain 4000 of the Caleta Santa Rosa, due to its high contamination as a result of industrial activities; it presents environmental problems that we must solve.The Maximum Permissible Limits for Effluents (LMP), issued by the Ministry of the Environment for domestic and municipal wastewater treatment plants, the Maximum Permissible Limits (LMP) for the fishmeal and fish oil industry, issued by the Ministry were applied. Of the production; and for marine waters, the National Environmental Quality Standards (ECA), giving high levels of pollution. The number of total and thermotolerant coliforms, total suspended solids and BOD5 (Biochemical Oxygen Demand) exceed the maximum permissible limits and the values established in the national environmental quality standards, causing a negative impact on the marine ecosystem. Th...

The influence of the addition of alkaline mass in the stabilization process of two waste water sludges was studied. The increase in the PH of the sludge, carrying it to values near to twelve, is due to the increase of alkaline mass additions during the stabilization of the residual sludge. This technique was used to stabilize the sludge and to give an agricultural valorization to the residual sludge. In this context, the problematic characteristics present in the sludge will lead us to a preliminary treatment of the sewage sludge.

The “Pintadilla” (Cheilodactylus variegatus Valenciennes, 1833) is a marine species that grows near the coast and is caught by artisanal fishing for human consumption. The objective of this study was to determine the concentration of mercury in this species in both muscle tissue and liver tissue. A total of 32 samples were collected, for 8 months, determining the concentration of total mercury using the cold vapor atomic absorption spectrophotometer. In general, the highest average concentration of total mercury was found in the samples collected in the Chorrillos Artisanal Fishery Market, both for muscle tissue (0.0563-0.2632 mg/kg) and for liver tissue (0.0464-0.2694 mg/kg), with respect to the Ancon Artisanal Fisheries Market, both for muscle tissue (0.0273-0.1193 mg/kg) and for liver tissue (0.0488-0.1911 mg/kg) all on a wet basis. It was observed that these results do not exceed...
