Database environmental data

TDS UMERICA. This is another source for numeric databases (58). This company provides different on-line databases and software for chemistry, engineering, and environmental data. A summary of its databases is contained ia Table 7.

A second initiative is being developed by Dr. Ann Richard and coworkers at the EPA. The Distributed Structure-Searchable Toxicity (DSSTox) public database network is a flexible community-supported, web-based approach for the collation of data. It is based on the SDF format for the representation of chemical structure. It is intended to enable decentralized, free public access to toxicity data files. This should allow users from different disciplines to be linked. Public, commercial, industry, and academic groups have also been asked to contribute to, and expand, the DSSTox public database network. Data from potentially any toxicological endpoint can be collated in the DSSTox public database network, including both human health, and environmental endpoints (Richard et al 2002 Richard and Williams, 2002). 

ATSDR health assessments are based on environmental characterization information, community health concerns, and health outcome data. Because of the nature of these databases, health assessments use quantitative as well as qualitative data, focusing on medical public health and toxicological perspectives associated with exposure to a site. The health assessment specifically addresses community health concerns (e.g., sensitive populations, possible disease outcomes) and evaluates relevant, community-specific health outcome data. Combined with environmental data, information obtained from those two data sources are used to determine the public health implications of the site guiding the initiation of follow-up health activities when indicated. 

SCAR experience of pooling marine environmental data from many contributors in the Biological Investigation of Marine Antarctic Species and Stocks (BIOMASS) database (14) showed that one of the major problems was that of data validation to ensure comparability of data. Existing environmental data are unlikely to be comparable between data sets and the value of these data will need to be assessed before embarking upon the collection of new environmental data. It will probably... 

ChemSpider currently searches over 14 million compounds in multiple chemical structure databases. These include databases of curated literature data, chemical vendor catalogs, molecular properties, environmental data, toxicity data, analytical data, and so on. ChemSpider intends to aggregate into a single database all chemical structures available within open access and commercial databases and to provide the necessary pointers from the ChemSpider search engine to the information of interest. This service will allow users to either access the data immediately via open-access links or have the information necessary to continue their searches into commercially available systems. 

Technology. To create plans, urban planners rely on tools such as mapping software and geographic information systems. These systems help planners assess existing land use and forecast the impact of recommended changes. Planners must also be skilled in the use of databases on population statistics and trends, laws and regulations, and geographic and environmental data. 

Toxicity, exposure, and environmental data on many of the commercial flame retardants can be found conveniently in an Anstralian database (148), which is supplemented as new products are imported. Ongoing assessments of flame retardants in use, particularly the brominated ones, and possible alternatives are published by the Danish Environmental Department (149). 

The Solvent Database contains data on physical and chemical properties as well as environmental fate, health, and safety. A total of 321 pure and trade name solvents can be compared in looking for alternative solvents.

Before these categories are looked upon in depth, the terms environmental data, environmental information, environmental database, and environmental information system should be defined.

An environmental database is a particular type of database that stores mainly environmental data. According to environmental informatics experts, a database can be called an environmental database if the following three conditions are fulfilled ...

A comprehensive search (295) of the STORET water quaUty database, maintained by the U.S. EPA Office of Water, is used to evaluate the potential water quaUty implications of various herbicides. This database contains information on contamination of surface water (SW) and groundwater (GW) suppUes. The data are provided to give a general impression of the occurrence of a given herbicide in SW and GW (269). The U.S. EPA scheme for categorizing a chemical s carcinogenic potential is used for herbicides for which healthy advisory information (HA) is available. The U.S. EPA is continually issuing HAs for various environmental contaminants HAs available in Reference 269 were used in preparation of this article.

There is also a growing number of specialized databases available on specific topics such as CEC Replacement, effluents and pesticides, environmental chemical data, etc. These are usually on CD-ROM or floppy disk (3). 

CALS combines sample tracking facilities with a database for management and documentation of information in the environmental wa.sie monitoring laboratory. EWOBS provides a reporting format that prints data on the NPDLiS form.
