Urea formaldehyde

 Urea formaldehyde is used in the production of formaldehyde resins, plywood, particle board, paper, and urea-formaldehyde foam. 
A study published in 1985 found mean exposures of 0.74 ppm (embalmers), 0.35 ppm (plywood manufacturers), 0.92 ppm (particle board manufacturers), 0.74 ppm (urea-formaldehyde foam manufacturers), and 0.42 ppm (urea-formaldehyde foam insulation installers). Formaldehyde causes eye irritation at 0.01-2.0 ppm, upper airway irritation at 0.10-25 ppm, lower airway and chronic pulmonary obstruction at 5-30 ppm, and pulmonary edema at 50-100 ppm. In a summary of health effects data, upper airway irritation and increased nasal airway resistance were reported at 0.1 to 25 ppm and lower airway and chronic pulmonary obstruction at 5 to 30 ppm
Bleach

 Bleach is commonly used as a household and commercial cleaner. It is corrosive to skin and inhalation exposure can cause damage to the lungs and even pulmonary edema. Ingestion can cause burning of mouth and throat and damage to the stomach. Household bleaches (approximately 5% sodium hypochlorite) are irritants; more concentrated bleaches (10-15% sodium hypochlorite) are corrosive.

    Which report did you find this information? I had a difficult time using the ToxNet website, and finding the exact information I needed for these two items. I also wish I had more education growing up about particle matter and the knowledge of what safe values of certain chemicals and irritants in our environments.

    I always knew bleach was bad, but the side effects are pretty bad given that many people use it daily, every where. Bleach is so cheap, and is used every where.

Household Products

The household products I looked up were dish soap and disinfecting wipes. The statements from the National Library of Medicine's Household Products Database are below. Method Dish Soap - "The product contains no substances which at their given concentration, are considered to be hazardous to health." Clorox Disinfecting Wipes - "This product is not considered hazardous by the 2012 OSHA Hazard Communication Standard (29 CFR 1910.1200)" Overall I found this database a little harder to use/understand than the EWG database for personal care products. I was a little surprised that the clorox wipes were not considered hazardous. My suspicion was that they were going to have a negative rating, but I was glad to find out that they were not as bad as I expected. While I could be making my own cleaning products using vinegar and baking soda, based on the database ratings I think I am making pretty good choices for my cleaning products and do not need to change at ...

Fragrance Free Policy

Fragrances in personal care products have been linked to a wide range of health issues from asthma, migraines, eye and skin irritation, allergies to cancer and reproductive issues. Fragrance is often found in lotions, perfumes, soaps, shampoos, makeup and deodorant. Most people use at least one of these personal care products on a daily basis, with the majority of people using many items each day containing fragrance.  An effective fragrance-free policy would be very difficult to design and implement. I know many hospitals have fragrance-free policies, but I am not certain how they enforce the policy. When I worked at a hospital, I was told not to wear perfume  or any personal products with fragrance, but I noticed that many people still did wear some fragrance.  I think the key to a fragrance-free policy would be to educate all employees. First, educate employees on what is considered a fragrance. Then, educate them on the potential harmful effects the fragrance ...

Obesogens

Image
Living in Northern California, we are lucky to have a lot of locally grown food and much of it is in season for much of the year. The Harvest Calendar below shows what is available by month in the Bay Area.  I think serving seasonal/local foods in hospitals is a good idea, but I don't know how feasible it is. In California I think this would be much easier than in a lot of other states.  I had not heard of obesogens before reading this article. It makes a lot of sense that consuming these chemicals would be bad for us and could alter metabolic processes and cause people to gain weight. I think more research should definitely done around this topic since obesity has become an epidemic not just in the United States but around the world. I chose monosodium glutamate (also known as MSG) as a potential obesogen to research. MSG is a food additive and is often used as a flavor enhancer. While it seems many studies have been done testing the effects of MSG, it is diffic...
