Abstract

A chemical database (PHYSCHEM) was created to supply parameters to a natural resource damage assessment model for marine and coastal environments. The database contains 18 parametric entries for each of 469 substances, including 9 crude oils and petroleum products. Sources of parameters are also coded into the database. Procedures for selecting parameters from databases or estimating parameter values were quasi-automated through a classification coding system, such that chemicals could be automatically keyed to the correct estimation procedures. Quality control of physical/chemical parameters was achieved by comparing parameters contained in reference databases and literature with values obtained through various estimation procedures. Toxicological parameters were drawn from databases using an automated decision tree, based on levels of quality control applied to the original data. The final database is available to the public in hard copy and on floppy disk.

化学数据库用于自然资源损害评估模型系统
建立了一个化学数据库(PHYSCHEM),为海洋和沿海环境的自然资源损害评估模型提供参数。该数据库包含469种物质的18个参数条目,其中包括9种原油和石油产品。参数源也被编码到数据库中。通过分类编码系统,从数据库中选择参数或估计参数值的过程是准自动化的,这样化学物质就可以自动输入正确的估计过程。通过比较参考数据库和文献中包含的参数与通过各种估计程序获得的值来实现物理/化学参数的质量控制。根据应用于原始数据的质量控制水平,使用自动决策树从数据库中提取毒理学参数。最后的数据库以硬拷贝和软盘的形式提供给公众。
