The work analyzes the influence of some pollutant elements due to metallurgical plants (defined as “metallurgical systems”) on the environment. The noise is an important pollutant factor. It can produce dangerous effects on the peoples as well as on the environment, buildings, animals and vegetation. The impact of pollutant metallurgical sources on the ecological systems is a complex issue. The complexity is due to the fact that the pollution is not a local problem, but it has also influences, through the most dynamic vectors on the environment, on very large zones (defined as ecozones). These effects can be observed at a regional and global level. The work takes into account the ecozones surrounding a metallurgical plant, their complexity and the possible interference as well. The study uses real data offered by some metallurgical plants, relating to pollutant agents and to their spreading zones. The final scope of the study is to establish the influence of these factors on the ecosystems where the metallurgical factory lay out and to offer a model that could make easier taking some decisions relating to the improvement of the utilized technologies.As the sources and severity of noise pollution continue to grow, there is a need for new approaches to reduce exposure.Keywords: Metallurgicalsystems, noise, pollution, efects, environment
