Industries and businesses in the United States use tens of thousands of chemicals to make the products we depend on, such as pharmaceuticals, computers, paints, clothing, and automobiles. Although the majority of toxic chemicals are managed by industrial facilities to minimize releases of chemicals into the environment, releases do still occur.
It is your right to know what toxic chemicals are being used in your community, how they are managed, whether they are being released into the environment, the quantities of these releases, and whether such quantities are increasing or decreasing over time.
You may know that the National Library of Medicine (NLM) has a number of resources related to environmental health and toxicology, including the suite of databases which are included as a part of TOXNET. NLM also has a number of resources on these topics which are specifically designed for the K-12 audience and the teachers and parents who work with these students. NLM’s Division of Specialized Information Services (SIS) is pleased to announce the launch of three interactive, educational iOS apps for middle and high school students studying biology, chemistry and environmental health.
These FREE, readily accessible resources assist students with grasping concepts such as DNA base pairing, the Bohr model of the atom and environmental conservation. Two of the iOS apps, Bohr Thru and Base Chase, were developed in collaboration with a high school educator and are easily usable within the biology/chemistry classroom setting. The third game, Run4Green, is a fun and informative learning tool that reinforces concepts relating to environmental conservation and can be used as an engagement extension activity.
Each of the three iOS games is iPhone, iPad and iPod touch compatible, and can be freely downloaded (with no in-game purchases) by visiting the iTunes App Store. Bohr Thru is a Candy Crush style game which requires players to collect and organize protons, neutrons, and electrons in order to form the Bohr Model of the first 18 elements in the Periodic Table. Base Chase allows players to grab bases of DNA in order to complete unique DNA stands for a variety of animals. This game compliments the GeneEd website. Run4Green is especially designed for grades 5-8 and reinforces environmental topics such as greenhouse gas reduction, renewable energies, and green product purchases.
The Radiation Emergency Medical Management Team is proud to announce the first major redesign of its site since REMM was launched in 2007. The redesign includes a more modern banner, a new color palette and font style, and a new navigation system.
There are now six content groups on the new home page and an easy-to-use navigational menu has been added with sections for:
• Interactive Clinical Tools
• Diagnosis and Treatment
• Reference and Data
• Overview of REMM and
• Links to downloading the REMM app for various mobile devices
One of the most popular features, the Multimedia Library in carousel form, remains on the home page, with several categories of multimedia assets.
Many significant content updates have been added to the website, including: new references in several sections, updates to a number of pages, a new email update system, and more.
All prior URLs have been retained. Users who have previously visited REMM pages may need to refresh (reload) the page to see the new design.
REMM is included as one of the resources in the NTC modular course “Discovering TOXNET.”

Did you know that you can view our tutorials and recordings at any time that’s convenient for you? If you have a few extra minutes, check out one of our self-paced tutorials or recorded webinars to learn something new or brush up on one of your most-used resources. Here are a few you might take a look at:
LactMed is part of the suite of TOXNET databases and provides information on drugs and other chemicals to which breastfeeding mothers may be exposed. With the new TOXNET interface, it was also updated. Check out this updated video from the National Library of Medicine to learn more about LactMed.
ChemIDplus, one of the resources available via TOXNET, has a new interface and updated functionality. ChemIDplus is a dictionary of over 400,000 chemicals with links NLM databases and other resources.
In the Advanced Search, a new “3D” button on search results pages provides calculated three dimensional structure models for over 300,000 chemicals and 645,000 variations. Users can adjust the rotation speed, the image type (ball and stick, space fill, wireframe), and 3D angle of viewing; dragging the image changes its orientation. Right clicking on the structure box provides other control options such as color, style, measurements, and computation.
