Drawing a Chemical Structure

Wednesday, November 19th, 2014

In the ChemIDplus Advanced search interface, you can draw a structure and search for similar substances. Here’s a quick tutorial on how to use the drawing feature of ChemIDplus.

New LactMed Video

Wednesday, September 17th, 2014

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.

 

Now Available in Wide Release: Searching the Hazardous Substances Data Bank

Monday, September 15th, 2014

A new how-to video called: Basics of Searching the Hazardous Substances Data Bank (HSDB) has been released by SIS featuring the newly updated TOXNET interface.

ChemIDplus Updated

Wednesday, July 23rd, 2014

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.

To see the changes, visit ChemIDplus, or read more about the changes in the NLM Technical Bulletin.

To learn more about ChemIDplus, watch for our updated tutorials on our Tutorials & Recordings page.

New TOXNET Class

Friday, July 18th, 2014

Discovering_TOXNET

New class, new format!

Discovering TOXNET is our new class that allows you to customize your learning experience of TOXNET and other NLM environmental health databases. The class is asynchronous and organized into 13 modules. All but one of the modules are optional, so you complete the segments that are of most interest to you. Each module consists of guided interactive online tutorials and/or tutorial videos as well as discovery exercises. Instructors will be available to answer questions and provide assistance throughout the course. The class runs over the course of 4 weeks and at the end of the course, you will receive MLA continuing education credit based on the number of modules you completed, up to 12 MLA CE hours. 

The modules are:

  1. Introduction to TOXNET: 0.5 hour (Required)
  2. TOXLINE: 1.0 hour
  3. ChemIDplus: 2.0 hours
  4. Integrated Risk Information System & Risk Assessment: 1.0 hour
  5. Hazardous Substances Databank: 1.5 hours
  6. Toxic Release Inventory: 1.0 hour
  7. TOXMAP: 1.5 hours
  8. Household Products Database: 0.5 hour
  9. LactMed: 0.5 hour
  10. Haz-Map: 0.5 hour
  11. WISER & CHEMM: 1.0 hour
  12. REMM: 0.5 hour
  13. LiverTox: 0.5 hour

What I’m Reading

It can be such a challenge to keep up with the literature, blogs, books, and other sources that help you to stay updated in your field. Here’s a short list of what I’ve been reading lately that you might also be interested in.

  • The Accidental Instructional Designer: Learning Design for the Digital Age, by Cammy Bean. I attended a presentation by Ms. Bean at the American Society for Training & Development TechKnowledge conference in January. (You can read a post about her presentation here). Her new book has great tips for both the novice and experienced designer of instruction, with a focus on e-learning. You can read a chapter of the book for free here.
  • Database Resources of the National Center for Biotechnology Information . This 2014 article by the NCBI Resource Coordinators provides updates on the suite of NCBI resources as well as a bit of background on the resources.
  • Fatal Victorian Fashion and the Allure of the Poison Garment,” by Allison Meier on the Hyperallergic blog. Interesting read on the dangers of style for both the wearers and the makers. And you can learn more about the toxicity of substances mentioned in the new TOXNET interface.
  • Getting Started with File Naming Conventions,” by Jake Carlson on the e-Science Community Blog. Very useful advice for someone like me who has been guilty of using “final” in a file name.

What interesting things are you reading lately? Let me know on Twitter @nnlmntc or Facebook!

Earth Day is Coming…April 22, 2014

Monday, March 10th, 2014

The first Earth Day was in 1970, the same year that the EPA was signed into law. Of the many databases offered by the U.S. National Library of Medicine (NLM) TOXNET®  is a suite of databases that cover toxicology data, hazardous chemicals, environmental health, and toxic releases.

What is TOXNET? A Little History.

The Toxicology Information Program (TIP) was established in 1967 at the National Library of Medicine (NLM) in response to recommendations made in the 1966 report “Handling of Toxicological Information,” prepared by the President’s Science Advisory Committee.

The objectives of TIP were to: (1) create automated toxicology data banks, and (2) provide toxicology information and data services. In the mid-1990’s, the mission of TIP was expanded to include environmental health and thus the Toxicology and Environmental Health Information Program (TEHIP) evolved.

TEHIP is responsible for the Toxicology Data Network (TOXNET), an integrated system of toxicology and environmental health databases that are available free of charge on the web.

The National Library of Medicine Training Center (NTC) offers online training about the TOXNET databases called Discovering TOXNET. One of the databases included in TOXNET is the Toxics Release Inventory (TRI). TRI data is collected by the U.S. Environmental Protection Agency (EPA).

What is TRI?

TRI tracks the management of certain toxic chemicals that may pose a threat to human health and the environment. TRI includes data about chemical releases, waste transfers, recycling and pollution prevention. TRI includes information that can help you learn about toxic chemical releases from certain facilities in your neighborhood.

Why was TRI created?

In December of 1984 there was a massive toxic gas release in Bhopal, India from a U.S. owned company. Thousands of people died on that day and thousands of deaths (approximately 8000) have been attributed to that accident. Later that same year, in West Virginia, there was another chemical release. While the W.V. release was on a much smaller scale than the release in India, people across the U.S. began to ask questions about preparedness and information about toxic releases from facilities in their towns.

How can TRI Help Communities?

  • TRI can identify which chemicals are released by TRI facilities
  • TRI can track increases and reductions of toxic chemical releases

What is a TRI Facility?

TRI facilities include manufacturing, coal/oil electricity generation, mining facilities, hazardous waste management and federal facilities. Companies in these industries must report their use of a TRI chemical if they manufacture, process or use more than a certain amount of a TRI chemical per year.

What is a TRI Chemical?

In general chemicals covered by the TRI Program are those that cause one or more of the following:

  • Cancer or other chronic human health effects
  • Significant adverse acute human health effects
  • Significant adverse environmental effects

The TRI Program currently covers 682 chemicals and chemical categories.

Haz-Map Updated

Friday, February 14th, 2014

NLM has updated Haz-Map with 481 new agents, including 23 agents causing occupational asthma. Fifteen new hazardous job tasks linked to jobs and industries were also added in this update.  Haz-Map now covers over 9170 chemical and biological agents and 241 occupational diseases. http://hazmap.nlm.nih.gov/

Haz-Map is an occupational health database designed for health and safety professionals and for consumers seeking information about the health effects of exposure to chemicals and biologicals at work.  Haz-Map links jobs and hazardous tasks with occupational diseases and their symptoms. It currently covers over 5997 chemical and biological agents and 235 occupational diseases.
