Environmental monitoring physical parameters

Parts 58.41 through 58.51 cover the physical facihties of the laboratory. The inspector must determine whether or not the facilities are of adequate size and design for completed or in-process studies. The physical parameters and systems of the facilities as they are used to accommodate the various operations employed in the GLP studies are examined. Investigators also deal explicitly with the environmental control and monitoring procedures for critical areas, especially the rooms used for animal housing, the test article storage areas, and the laboratory areas in which biohazardous material is handled. The procedures and methods for cleaning equipment and areas critical to study conduct as well as the cur-... 

Environmental monitoring programmes must specifically be targeted towards environmental parameters relevant to the local ecosystem. The following variables generally indicate the physical condition of water during dredging and reclamation works ... 

Monitoring programs measuring total concentrations should include measures of parameters (environmental characteristics, for example, clay, organic carbon content, pH, dissolved organic carbon (DOC)) and physical chemical properties of compounds that help to evaluate bioavailability. 

A three year study monitoring acid precipitation across Central Indiana has just been completed by the authors ( ) and the local International Rotary Club who donated the manpower for sample collection. Over 3000 individual samples were collected during approximately 300 individual precipitation events. Using acceptible analytical and statistical protocol, the samples were characterized by meteorological, physical, and trace chemical composition data to determine possible sources of the acidity. The study yielded pertinent environmental data that set the parameters for this work. 

Natural environment and infrastructure monitoring is very important for environmental security. Note that only the infiastructure - the built component of the environment - besides being monitored, can also be controlled and modified by humans. The natural environment can only be monitored, and its status - for example, the weather conditions - taken into consideration in action planning. Natural environment and infrastructure can be consider like a metastable physical system. The decline of the stability of the natural environment (according to his parameters) can be a long process and expensive to the reconditioning. 

The programmes of radiation monitoring substantially depend on the characteristics of the release source, release medium and release rate, radionuclide composition and physical and chemical form of the released radionuclides, and on environmental parameters in the area contaminated with radionuclides. They also depend on the possibilities of control of the release in cases of practices and interventions. Different techniques and programmes are applied for the monitoring of a release source (stack, discharge pipe, etc.) or radioactive contamination of the environment.
