Secondary contamination degree

The degree of contamination governs the performance and product quality and affects the utility value of the end product. Secondary contaminants such as additive agglomerates are included in the term contamination . Particularly in case of film polymers, such particles diminish the quality of audio or video tapes due to the vulnerability of films to this drop-out phenomenon. 

The degree to which a patient is decontaminated in the prehospital setting depends on the decon plan, available resources, the weather, and patient volume. At minimum, every patient presenting a risk of secondary contamination risk should receive gross decon before departing for the hospital. These patients should be transported to a hospital (by properly protected EMTs and paramedics). The receiving hospital should be... 

The degree of secondary contamination on patients who have been removed from the hot zone is considerably less than the contamination at the point of release. This means that heavy, self-contained suits with SCBA are not necessary. 

The extent of racemization of several amino acids in a fossil bone can also be used to determine the degree of secondary amino acid contamination (22). Elevated temperature kinetics experiments have shown that the extent of amino acid racemization in a bone should have the... 

Acceptance of air pollution models in decision-making will depend on the degree of confidence that can be placed in their predictions. The validity of a model is established by carefully comparing its predictions with air quality data for the particular airshed. Air quality models capable of predicting concentrations of primary (those emitted directly) and secondary (those formed by chemical reaction in the atmosphere) contaminants at any time and location in an airshed must clearly be based on sound fundamentals of meteorology and chemistry.
