Análise química de solos: estudo de casos

Abstract

Man’s action on nature is something that has grown over time. The uncontrolled extraction of resources has been growing as the need is present. With the advent of the industrial revolution, this extraction became quite exponent. The withdrawal of metals for the production of materials increased as never before, one of the problems that this caused was the improper disposal of those products that contain these metals. Whether in rivers or in soils, the impacts that are generated on the environment are very serious. Green chemistry emerged as a way to help in the production and disposal of these materials. With a set of 12 practices that are less aggressive to the environment, they try to contain this rampant pollution. Green chemistry is one of the means of combating this very pertinent practice, the other would be through legal means. In Brazil, there are a number of laws and regulations aimed at controlling and reducing soil pollution by metals. Unfortunately, however, some laws are not followed and the environment is harmed. In this work we will analyze the presence of metals in several soil samples taken from different locations.
