This is a website by Syracuse Research Corporation. It contains numerous reference information including a link to the PBT profiler that SRC created for the U.S. EPA – this model predicts risk related data (physical/chemical properties, bioconcentrations, environmental fate, carcinogenicity and toxicity). There is also a link to a childhood lead risk assessment model, environmental fate database, and a physical properties database (> 25,000 chemicals). All the latter requires is a CAS number be entered.
The website is available here .
