The men's search for improvement and confort has changed their "habitat" and simultaneously it has resulted in a increasing of pollution activities that damages, chieffly, the air and water quality which are necessary recourses for their healthy. Therefore, the urban center growth has been always followed by an increasing of environmental concern.

The foundation of water code (water law) in 1934 and forest code (forest law) in 1965 in Brazil are some of the most important matters for the continous search of legal instruments concerning the environmental control which precedes the EIAs RIMAs's compulsoriness.

The EIAs RIMAs appeared in 1977 in Rio de Janeiro State following the introduction of nuclear power station. The concern about the environment came out in Brazil as a result of environmental politics in the 70's, especifically in the USA and West Europe (with more emphasys in England, France, Germany and Sweden) when the Green Parties emerged.

This work concerns the EIAs RIMAs working out diagnostic in Rio de Janeiro State during the 70's, 80's and 90's. The work was basically developed through available data from each explored EIAs RIMAs and they were transformed in 4 tables in the following way:

Table 1: Place, Year, EIAs RIMAs type.
Table 2: Mainly subjects of each EIAs RIMAs.
Table 3: Responsable professionals by building up the EIAs RIMAs.
Table 4: Impacts and risks associated with the EIAs RIMAs.

Starting from the EIAs RIMAs analysis during the survey and tables, it was possible to realize that most executed EIAs RIMAs, until the present moment are not reaching the purposes estabilished by the Law.
