Deployment precautions

In subsequent chapters, we provide an overview of SPMD fundamentals and applications (Chapter 2) the theory and modeling which includes the extrapolation of SPMD concentrations to ambient environmental concentrations (Chapter 3) study considerations such as the necessary precautions and procedures during SPMD transport, deployment, and retrieval (Chapter 4) the analytical chemistry and associated quality control for the analysis of SPMD dialysates or extracts (Chapter 5) a survey and brief description of bioassays-biomarkers used to screen the toxicity of SPMD environmental extracts (Chapter 6) discussions on how HOC concentrations in SPMDs may or may not relate to similarly exposed biomonitoring organisms (Chapter 7) and selected examples of environmental studies using SPMDs (Chapter 8). In addition, two appendices are included which provide... 

A total of 80 tons of liquified phosgene gas (originating from military demobilization stocks) was thus stored within a populated city, without the deployment of any particular safety precautions. Had the gas release occurred on any day other than Sunday, the fatalities would... 

Commercial power disrupted and TOCDF changed to emergency backup power. ACAMS alarmed in the DFS due to the interruption of the airflow. As a precaution TOCDF suspended munition processing and RTAPS deployed with negative readings. Demil process resumed after commercial power restored. 

One of the main problems with solid adsorbents is that of obtaining satisfactorily low and reproducible blanks. Even if adsorbents can be adequately cleaned in the laboratory, very elaborate precautions must be adopted to prevent recontamination (and in the case of some synthetic resins, degradation) before deployment. Further problems may be encountered with in situ systems where the extended deployment times leave the sample (and adsorbent) vulnerable to bacterial attack.
