Source Ranking Database
What Does SRD Do?
Performs a systematic screening-level review of over 12,000 potential indoor
pollution sources to identify high-priority product and material categories
for further evaluation.
Can also identify the products that have contained a specific chemical.
How Does SRD Work?
Produces risk-based rankings by multiplying an estimated indoor-air concentration
by a hazard score for each chemical in a given product or material and for
each environment in which the product/material is used.
Allows users to display the scores for constituent chemicals, as well as the
overall product scores and rankings.
Instructions to install and run the model are not presented here.
What Do I Need to Use SRD?
SRD contains all of the information needed to create product rankings. No
specific user inputs are required.
Users can create their own product groupings in addition to the default groupings
provided by the program (these are based on Standard Industrial Classification
codes).
Users select the indoor environments (e.g., office building, residence, hospital,
shopping mall) to be evaluated by the ranking algorithm.
Users also choose between 'high' and 'average' values for key exposure parameters
(e.g., product usage rates) evaluated by the ranking algorithm.
How Are SRD Data Used?
To produce ranked lists of products or product categories that contribute
to indoor air pollution.
To identify the relative contribution of each constituent chemical to a consumer
product's risk score.
To identify what products a specific chemical has been used in.
What Type of Computer System Do I Need?
Hardware: IBM-compatible computer with a 486 or Pentium microprocessor
(minimum speed: 33 MHZ) and 640K memory
.
What Is SRD's Status and Availability
A final version of this program is currently available in a Windows-based
format. SRD has been peer reviewed by the Science Advisory Board and the comments
from that review have been incorporated into the model. This model was developed
under contract by Versar Inc. for the EPA Office of Pollution Prevention and
Toxics, Economics, Exposure, and Technology Division, Exposure Assessment
Branch (EAB).
SRD can be downloaded and installed using Download SRD.
