The Pitangui stream, beyond an important tourist point, possesss a diversity of water fish marine candy and fish reasonable, and the same it presents also stretches of ciliar bush alternating with stretches without vegetal covering. The alteration of the vegetation delinquent will be able to cause negative impacts in ictiofauna, in view of that some species of fish have more cold water necessity to obtain to live and if to reproduce. The impacts that cause change can be diverse, as the increase of the temperature of the water due the biggest incidence of solar rays, minor oxygenation of the water due the seaweed proliferation, as well as can affect the maturation of eggs of some species of fish; The vegetation has great importance in what if the interception of nutrients says respect and sediments that adentram the river, exchanges of organic substance enter the terrestrial way and the aquatic one. For this reason, we opt to testing the influence of the vegetal covering on ictiofauna of the Pitangui stream, in the city of Extremoz, Rio Grande of the North. We have as objective to verify the importance of the vegetal covering for the community of fish through the comparison a stretch of the stream with the presence of ciliar vegetation and above of the Cachoeirinha de Pitangui that can serve as barrier for the water and salty water fish candy, and the other stretch without the influence of the ciliar vegetation and below of the waterfall enters, being a estuarina region. From collections with a net of Drag we will go to verify if it has difference in the composition of species found in the places covered for the vegetation delinquent or in the opened stretches, above and below of the fall d’ water. As analysis of the data we will use the index of diversity of Simpson, Wealth, Equitabilidade and Test t as method of comparison of the two areas to base the part statistics of our work. With this, we also wait to acquire knowledge the native population and the visitors, for the preservation and conservation of ictiofauna and the ambient integrity of the rivers. PALAVRAS-CHAVES: Water fish candy, ciliar vegetation, estuary, ambient awareness, impacts in the population of fish.
Any substance found in the atmosphere in a different ratio of a natural situation is considered as a pollutant atmospheric that not only presents problems for the population for immission of pollutants, next to the point to emission, but also in more distant zones for the effect of dispersion in air. The main urban sources of pollution are the automachine vehicles complemented by the industrials and the activities of restaurants and bars. The Municipal City hall of Victory fulfilling its objective of Municipal Politics of Environment established norms, criteria and standards of emissions of effluent and ambient quality that has for goals the control, the licensing, the monitoramento and the fiscalization of the polluting and degrading activities of the environmental resources of the City. For this the Environment Secretariat Half of Victory? SEMMAM, elaborated Instructions Techniques and Norms procedural to guide and to subsidize the entrepreneurs, in what it refers to the elaboration, implantation and implementation of studies and/or projects of ambient control. To facilitate to this procedure the city hall of Victory 001/2000 created the Instruction Technique n, in compliance with Federal legislation NBR 14.518/2000. 2? JUSTIFICATION Due the complexity of the subject, its understanding and the necessity of an aid technician for initial elaboration of a deeper study and its costs for implementation, appeared the necessity to create a practical script for the agreement of the procedure and funcionabilidade of the system of treatment of atmospheric emissions of the activities of Bars and Restaurants of the great Victory. The work will approach the necessary phases to the control of the emissions in question: captation, treatment and the disposal adjusted in the external environment preventing and diminishing the impacts to the environment and third (atmospheric, thermal and sonorous pollution), the described one in Municipal code of Environment of the city of Victory, Lei4.438/97.
Due to abundance of the water in the planet, never had a bigger concern of the industrial area with this subject, but the water consumption in the industrial processes in Brazil has provoked serious ambient impacts due to scarcity of this resource, so precious. The investment in technology I reuse to promote it of used waters has been each required time more, especially for the industries of great transport, beyond, clearly, of the initiatives of conservation of this good, through the elimination of wastefulness. The economic and social aspects also must be analyzed in this context, therefore the water is an essential resource to the life and must be supplied in the amount and necessary quality all. The recycling concept or I reuse of the water is not new in history. Of course, this occurs has much time.
Planned ways of I do not reuse benefit to cities and industries that use ebb tide water that already had been used and returned to the rivers. This is an indirect form of the use. What it occurs is that currently, the pollution of this way has made it difficult this process. Of this form, the development of a direct form became necessary of reuses, that it consists of the treatment of an effluent one for its reutilizao. This process is not easy and depends on investment in technology, but with the current ambient, each time more restrictive, searching requirements and specialists already had obtained to prove over all that this investment is interesting and viable, in the industrial area. The collection of the water was established for the management of the hdricos resources, as well as promoting the use of this benefit of more rational form. In this aspect I reuse, it of the water in the industrial processes also characterize reduction in the production costs, beyond promoting the recovery, preservation and conservation of the hdricos resources.
