M4.2 National Library ToxNet


Health Effects of Exposure to common chemicals

  • Using the National Library ToxNet database (specifically the HPD and HSPD databases), I was able to find out a lot about the negative health effects associated with exposures to urea formaldehyde, which is found in pressed board- a common building material that I had never even heard about, but that most of us are exposed to almost daily. One health effect associated with urea formaldehyde exposure is cancer of the nasopharynx and leukemia. Additionally, a study of female workers in the garment industry showed that exposure caused an increased incidence of menstrual disorders,  inflammatory disease of the reproductive tract, sterility, anemia, and low birth weights among offspring.
  • Using the National Library ToxNet database (specifically the HPD, HSPD, and TOXLINE databases), I was also able to find out a lot about the negative health effects associated with exposures to bleach, which is a common cleaning product that I have used many times in the past. One health effect associated with bleach exposure is skin, eyes, and upper respiratory tract irritation. It has also been linked to severe inflammation, vomiting, burns, and edema.

M10.5 Blog about an occupational safety and health organization

CHOOSE ONE of the following organizations/agencies: OSHA, CAL/OSHA, NIOSH, ILO, WHO, AFL-CIO Go to their website. Each of these occupational safety and health or labor organizations support a range of occupational health and safety programs. Select a health and safety program sponsored by one of these organizations, read about it. Provide a short summary on your BLOG and how it might relate to your health and safety. I chose the National Institute for Occupational Safety and Health (NIOSH) as the agency to explore for this blog post. I went to their website (link:  https://www.cdc.gov/niosh/index.htm ) and looked at all the different health and safety programs that they sponsor. The program I chose to read about in more depth is one of the programs in the NIOSH Research Program Portfolio. The program I read about the NIOSH Occupational Health Equity Program. The NIOSH Occupational Health Equity Program "seeks to promote health equity in disease incidence, injury, mental ...

M9.3 Blog: Green Chemistry

Green chemistry is the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. Green chemistry applies across the life cycle of a chemical product, including its design, manufacture, use, and ultimate disposal. Green chemistry is also known as sustainable chemistry. Green chemistry: Prevents pollution at the molecular level Is a philosophy that applies to all areas of chemistry, not a single discipline of chemistry Applies innovative scientific solutions to real-world environmental problems Results in  source reduction  (Links to an external site.)  because it prevents the generation of pollution Reduces the negative impacts of chemical products and processes on human health and the environment Lessens and sometimes eliminates hazard from existing products and processes Designs chemical products and processes to reduce their intrinsic hazards Green chemistry reduces pollution at its source by minimi...

M10.2 Blog about MSDS and ToxNet

Obtain a Material Safety Data Sheet (MSDS) from your workplace or from the workplace of a family member or friend.   Material Safety Data Sheets are chemical information sheets created by chemical manufacturers that all employers are required to obtain and keep for any potentially hazardous chemicals in the workplace. For this blog post, I tried to find a material safety data sheet (MSDS) from UCSF. The MSDS I found is for "Equi-soft Foam Antimicrobial Handsoap"  Here is a link to the MSDS:  https://cleanhands.ucsfmedicalcenter.org/docs/Product%20information/Arichive/Equi-soft_Foam_MSDS.pdf Review  the MSDS and answer the following questions: What are the health risks associated with this chemical? There are four chemicals in the antimicrobial handsoap:  2-methylpentane-2,4-diol; amines, coco alkyldimethyl, n-oxides; Polyethylene Glycol; and benzalkonium chloride.  The health risk associated with these chemicals is they can cause eye irrita...
