The U.S. Environmental Protection Agency is making it easier to find data about chemicals by releasing two databases — the Toxicity Forecaster database (ToxCastDB) and a database of chemical exposure studies (ExpoCastDB) — that platers and finisherts can use to access chemical toxicity and exposure data.
ToxCastDB users can search and download data from over 500 rapid chemical tests conducted on more than 300 environmental chemicals. ToxCast uses advanced scientific tools to predict the potential toxicity of chemicals and to provide a cost-effective approach to prioritizing which chemicals of the thousands in use require further testing. ToxCast is currently screening 700 additional chemicals, and the data will be available in 2012.
ExpoCastDB consolidates human exposure data from studies that have collected chemical measurements from homes and child care centers. Data include the amounts of chemicals found in food, drinking water, air, dust, indoor surfaces and urine. ExpoCastDB users can obtain summary statistics of exposure data and download datasets. EPA will continue to add internal and external chemical exposure data and advanced user interface features to ExpoCastDB.
The new databases link together two important pieces of chemical research — exposure and toxicity data — both of which are required when considering potential risks posed by chemicals. The databases are connected through EPA’s Aggregated Computational Toxicology Resource (ACToR), an online data warehouse that collects data on over 500,000 chemicals from over 500 public sources.
Users can now access 30 years worth of animal chemical toxicity studies that were previously only found in paper documents, data from rapid chemical testing, and various chemical exposure measurements through one online resource. The ability to link and compare these different types of data better informs EPA’s decisions about chemical safety.

One of the most common problems that can arise when plating with alkaline zinc is an imbalance of brightener in the solution. In this helpful Ask the Expert article, Chad Murphy of Columbia Chemical discusses how different zinc metal concentrations and brightener concentrations can impact efficiency.

Dear Products Finishing Audience Member:
Starting on Thursday August 8, 2024, PF will begin “gating” its premium content, asking all new website users to provide some information about themselves — name, title, employer, email address — before they are provided free access to the content.
We are doing this because the ways PF’s audience finds and accesses our content is changing. Google’s search algorithms, increasingly, make it difficult to connect PF’s content with the people who might make use of it. On top of that, generative AI like ChatGPT is serving up PF content to internet users without attributing that content to PF.
As a result, it has become increasingly important for PF evolve its audience development strategy and learn as much as possible about who is accessing our content, what content they are accessing and how they are accessing it.
With this audience development strategy, we hope to do two things:
First, we will be better able to deliver directly to our audience the editorial content that aligns with the surface finishing materials, processes and technologies that interest them.
Second, we will be better able to connect the materials, equipment and services our advertisers supply with the audience that is most interested in them.
PF plays a distinctive role and has earned a place of esteem within the focused and specialized industry it serves. Large developments in the media landscape are forcing us to change the way we communicate with our audience. We are confident that our audience values the role PF plays in their professional lives and will join us in this effort to stay connected to them.
We thank you for your continued interest in and support of PF and welcome any questions you might have about the brand’s new content gating strategy.
