Inventory of Data

Understanding the resource demand for data collection is critical to successfully designing the improvement effort to obtain valid data. Equally important is to provide the resources for data analysis. Creating a large inventory of data that is not used will not only waste resources but will become frustrating for those who expect to see results that never materialize. It is better to collect less of the most critical data and complete a proper analysis than it is to collect a lot of data and never use it, A critical part of the improvement effort design is to define the data collection and analysis resource needs.

The amount of HEU that becomes avadable for civdian use through the 1990s and into the twenty-first century depends on the number of warheads removed from nuclear arsenals and the amount of HEU in the weapons complex that is already outside of the warheads, ie, materials stockpdes and spent naval reactor fuels. An illustrative example of the potential amounts of weapons-grade materials released from dismanded nuclear weapons is presented in Table 7 (36). Using the data in Table 7, a reduction in the number of warheads in nuclear arsenals of the United States and Russia to 5000 warheads for each country results in a surplus of 1140 t of HEU. This inventory of HEU is equivalent to 205,200 t of natural uranium metal, or approximately 3.5 times the 1993 annual demand for natural uranium equivalent. 

The LD q for sodium bromide taken orally by rats is 3.5 g/kg body weight, and the TD q orally in rats is 720 mg/kg (8). RTECS Hsts data on reproductive effects in male and female rats. Sodium bromide is Hsted in the TSCA Inventory, the Canadian Domestic Substances Hst (DSL), the European Inventory of Existing Commercial Chemical Substances (EINECS), the Japanese Existing and New Chemical Substances (ENCS), and the Korean Existing Chemicals Hst (ECL). It is not regulated by the U.S. Department of Transportation. 

In the European Union, coal-derived complex chemical substances, ie, those contained in the European Inventory of Existing Commercial Chemical Substances, have been classified for carcinogenicity in the twenty-first adaptation to technical progress of the European Commission (EC) Dangerous Substances Directive 1994 67/548/EEC (57). The EC Regulation 793/93 requires data sets to be submitted by producers or importers to the... 

The Toxic Substances Control Act (TSCA) was enacted in 1976 to identify and control toxic chemical ha2ards to human health and the environment. One of the main provisions of TSCA was to estabUsh and maintain an inventory of all chemicals in commerce in the United States for the purpose of regulating any of the chemicals that might pose an unreasonable risk to human health or the environment. An initial inventory of chemicals was estabhshed by requiring companies to report to the United States Environmental Protection Agency (USEPA) all substances that were imported, manufactured, processed, distributed, or disposed of in the United States. Over 50,000 chemical substances were reported. PoUowing this initial inventory, introduction of all new chemical substances requires a Premanufacturing Notification (PMN) process. To be included in the PMN are the identity of the new chemical, the estimated first year and maximum production volume, manufacture and process information, a description of proposed use, potential release to the environment, possible human exposure to the new substance, and any health or environmental test data available at the time of submission. In the 10 years that TSCA has been in effect, the USEPA has received over 10,000 PMNs and up to 10% of the submissions each year are for dyes (382)... 

Adequate support from the facility staff is absolutely essential. The facility staff must help the analysis team gather pertinent documents (e.g., PSilDs, procedures, software descriptions, material inventories, meteorological data, population data) and must describe current operating and maintenance practices. The facility staff must then critique the logic model(s) and calculation(s) to ensure that the assumptions are correct and that the results seem reasonable. The facility staff should also be involved in developing any recommendations to reduce risk so they will fully understand the rationale behind all proposed improvements and can help ensure that the proposed improvements are feasible. Table 12 summarizes the types of facility resources and personnel needed for a typical QRA.

The risk inventory or risk evaluation is die ne. t part of die hazard survey. It is not practical to expect the plan to cover every potential accident. When die hazards liave been evaluated, die plan should be focused on die most significant ones. This risk assessment stage requires die technical expertise of many people to compare die pieces of data and detennine die relevance of each. Among die important factors to be considered in performing die risk evaluation are die following ...

Over the years, many instruments have been developed for and used in the scientific laboratory. Today, the computer is used as a major tool in the scientific laboratory for the capture, manipulation, transfer, and storage of data. Consequently, the concern for data quality has shifted from the instruments that are used in the generation of the data to these electronic systems, often neglecting the fact that the data are only as accurate as the instrument measurements. For instance, many electronic systems can be used in chromatography analysis, from the electronic log book where the test substance inventory is kept, throughout data capture in the instrument, to the digitized electronic signal that is the raw data on the computer network. For crop residue samples, the...

Although this section does not present historical information regarding TRI chemical releases over time, note that, in general, toxic chemical releases have been declining.13 Although onsite releases have decreased, the total amount of reported toxic waste has not declined because the amount of toxic chemicals transferred offsite has increased. Better management practices have led to increases in offsite transfers of toxic chemicals for recycling. More detailed information can be obtained from U.S. EPA s annual Toxics Release Inventory Public Data Release book, or directly from the Toxic Release Inventory System database. 

The inventory tasks is to collect environmentally important information about relevant processes involved in the product system. Inventory collects information about unit processes at first and subsequently, an inventory of inputs and outputs of the system and its surroundings is carried out. The goal is the identification and quantification of all elementary flows associated with product system. Inventory analysis is the nature of the technical implementation of LCA studies. It is an essential part of a study, has high demands for data availability, practical experience in modelling product systems and, in the case of using database tools, it is necessary to master them perfectly and to understand their function [46]. The inventory phase principle is data collection that is used to quantify values of the elementary flows. This phase represents a major practical part of the LCA study, time consuming and with demands for data availability and author s experience with modelling product system studies [47],... 

The scope of the case study is depicted in Fig. 2. In the inventory, average data on emissions and consumptions, typically based on 5-10 data points (depending on the parameter) from a total of 71 Danish and Swedish printing houses and European literature values, are used (foreground data). For the upstream and downstream emissions and consumptions (background data), inventory data from databases like EDIP LCV tool [12] and literature like BUWAL [13] and data from Swedish paper mills [14] have been used. In the main scenario, it is assumed that 53% of the paper is recycled and the rest incinerated (Danish situation in year 2000). 

The rather thoughtless use of chemical compounds for plant protection in the second half of the XX century has brought about the accumulation in the storehouses of some facilities of about 1000 tons of preparations that are unfit for use, forbidden or unidentified. The sanitary and epidemiological service jointly with the Ecological inspection and the District station for plant protection are conducting an inventory of the storage sites of these toxic wastes. Inventory data with indications for the place of the storage, the names of the preparations and their quantity is kept in a computer database. 

Table 4-1 lists information on U.S. companies that reported the manufacture and processing of hexachloroethane in 1993 (TRI93 1995). The Toxics Release Inventory (TRI) data should be used with caution since only certain types of facilities are required to report. This is not an exhaustive list. 

Therefore data on anthropogenic and natural emissions in the Asian region are necessary for the assessment of heavy metal pollution in these countries. Pollution of Kazakhstan and Kyrgyzstan by mercury and lead has been initially assessed by means of hemispheric modeling using the available global emission inventories of the considered heavy metals. The outcomes of the assessment are presented in this section. 

Worst-case scenario. When considering the stationary source s worst-case scenario, there are selection factors to be considered. In addition to the largest inventories of a substance, the following conditions must also be considered smaller quantities handled at higher process temperatures and pressures, and proximity to the boundary of the stationary source. Sources must analyze and report additional worst-case scenarios for a hazard class if the worst-case scenario from another covered process affects a different set of public receptors than the original worst-case scenario. It is interesting to note that worst-case release data indicate that the distances and thus the populations that could be threatened are greater for toxic substances than for flammable substances.
