Environmental emergency defined

An environmental disaster is defined as an environmental emergency or ecologic disruption of a severity and magnitude resulting in deaths, injuries, illness, and/or property damage that cannot be effectively managed by the application of routine procedures or resources and that result in a need for additional assistance. The consequences of the damage to the environment will vary based on the type of hazard, the mechanism of its... 

A eombination of the eonstituents attributes together with the environmental attributes defines all of the emerging properties of the system. 

Chemiluminescence has been studied extensively (2) for several reasons (/) chemiexcitation relates to fundamental molecular interactions and transformations and its study provides access to basic elements of reaction mechanisms and molecular properties (2) efficient chemiluminescence can provide an emergency or portable light source (J) chemiluminescence provides means to detect and measure trace elements and pollutants for environmental control, or clinically important substances (eg, metaboHtes, specific proteins, cancer markers, hormones, DNA) and (4) classification of the hioluminescent relationship between different organisms defines their biological relationship and pattern of evolution. 

Remediation optimization uses defined approaches to improve the effectiveness and efficiency with which an environmental remedy reaches its stated goals. Optimization approaches might include third-party site-wide optimization evaluations conducted by expert teams, the use of mathematical tools to determine optimal operating parameters or monitoring networks, or the consideration of emerging technologies. Since 1999, U.S. EPA has promoted remediation optimization in the following manner ... 

Natural attenuation is defined by the U.S. Environmental Protection Agency s (EPA s) Office of Solid Waste and Emergency Response (OSWER) as follows ... 

The 1970 amendments represent landmark legislation (5). Not only did the law create the Environmental Protection Administration (EPA) as a separate agency reporting directly to the President, but it established schedules and a regulatory mechanism to treat air quality on a national basis. No longer could an industry find pockets of laxity from state environmental controls. Air quality was defined in legal tests and emerged as a new concept,...
