Basically interaction matrix is a two-dimensional listing, row listing and vertical listing constitutes impact interaction between each elements of characteristics and conditions of the environment and proposed actions that may affect the environment.
I will give a very simple application of check list approach to identify the impact and gather all relevant information and value them in terms of importance and magnitude of the impacts. Suppose you are government official in your environmental agency in your city. You receive a proposed project to build a huge shopping mall in a certain area located in the center of the city, thus in a very crowded area. Identify and value the importance and magnitude of the impacts that may arise.
Gel filtration chromatography or perhaps just gel filtration is used to separate or purify protein based on the size properties. These protein include enzyme, polysaccharides, nucleic acids and other biomolecules. There are two kinds which technique can be applied. One is for group separation, and second is for high resolution fractionation of biomolecules.
Okay, I have mentioned about environmental identification or inventories, let us move to the next step which is environmental assessment.
Brief overiew of impact assessment has been explained in previous post. As it has been mentioned, one crucial part of impact assessment is inventory. The inventory here means to identify, to note, to gather all information and factors that may be affected by proposed projects or actions.
Basic overview of impact assessment has been provided from previous post. As you are probably aware, from the embrio of environmental impact assessment long time, as time runs, the implementation has evolved into something more social.
Impact assessment history began at 1970, it was the President, Richard Nixon, who signed NEPA into law, establish a national policy to encourage “productive and enjoyable harmony” between people and their environment. Because of that, the Council on Environmental Quality (CEQ) was established with its main job to monitor the environmental effects of all federal activities, assists the President in evaluating environmental probles and determines solutions to these problems.
