M4.2 National Library ToxNet

Individuals may be exposed to toxic chemicals in their daily home, such as urea formaldehyde and bleach. Urea formaldehyde is found in pressed board, which is a common building material, and bleach is a common cleaning and disinfectant product used in the home as well as the hospital setting, among others. The toxnet database provided by the U.S. National Library of Medicine is an excellent source to assess risk of chemicals we may be exposed to daily.

Urea Formaldehyde

·      Respiratory irritation

·      Increased cancer risk (concentrations > 3.0-5.0 ppm)

·      Allergic reactions (ie. Watery eyes, wheezing, cough)

·      Burning sensation (in eyes, throat)

·      Malaise

·      Insomnia

·      Anorexia

Bleach

·      Esophageal & gastric erosion (when ingested)

·      Dry skin

·      Nervous system damage

·      Respiratory irritant

·      Migraines

Urea-formaldehyde is very common throughout the household and most buildings. It can be used in textiles, fabrics, and wood glue, among others. It has agricultural and textile use, but causes health problems when formaldehyde is released into the air. If concentrations of formaldehyde are less than 1.0 ppm, there are generally no noticeable health effects. However, side effects and cancer risks when formaldehyde levels rise.

Bleach is used as a disinfectant and cleaner in homes and industrially. It has a broad-spectrum antimicrobial effect that allows it to denature most pathogens. While its uses are beneficial, excessive usage can produce organochlorines and dioxins that provides significant respiratory risk to individuals.
