Environmental Quality is a set of properties and characteristics of the environment, either generalized or local, as they impinge on human beings and other organisms. It is a measure of the condition of an environment relative to the requirements of one or more species, any human need or purpose.[1]
Environmental quality includes the natural environment as well as the built environment, such as air, water purity or pollution, noise and the potential effects which such characteristics may have on physical and mental health.[2]
