Urea formaldehyde foam insulation (UFFI) is injected as a mixture of urea formaldehyde resin, an acidic foaming agent, and a propellant, such as air. It was commonly used in existing houses by injecting the foam into areas, such as behind walls, where it was impractical to provide conventional insulation. UFFI has been suggested as a causal agent in a variety of health problems, including upper and lower respiratory tract and gastrointestinal tract symptoms, asthma and chronic bronchitis, dermatitis, psychological symptoms (including insomnia and depression), nasal cancer and lymphoma.

Sodium Hydroxide commonly known as our household bleach is a hazardous product that should be handled with caution. Many of its adverse associated health effects from its exposure are from direct skin contact, inhalation or ingestion. Common health effects include irritation of skin, eyes, lungs and lightheadedness; and is linked to triggering or worsening symptoms of asthma.

    I appreciate the definition you have provided Claudia for UFFI. I think it is highly important to know about what is in the agents and how we can be safe around these products, especially bleach. It is dangerous to be around and I would hope we take the proper precautions to protect ourselves.

M9.2: Six Chemical Classes

1-Highly Fluorinated : Products that are highly fluorinated are man made and is found in several products that we use daily, it can be found in nonstick cook wear and waterproof items. These chemicals are toxic to our health and remain in our environment permanently. These chemicals were found in 98% of Americans, the development of fetuses and infants are in jeopardy from exposure to these chemicals. C8 and PFOA are linked to kidney, testicular cancer, elevated cholesterol, decreased fertility, thyroid disease and hormonal disruption HF bioaccumulates and does not breakdown thus damages the environment.  How can we protect ourselves: A-Choose textiles and carpeting without water- and stain-repellent B-Avoid food with grease proof packaging, such as microwave popcorn and some fast food. C-Avoid personal care products with "PERFLUR", "POLYFLUOR" nad "PTFE" on the label. D-Be way of products labelled "PFOA FREE", they often contain sim...

M10.8 Blog about an occupationally-related disease

The primary pneumoconioses are asbestosis, silicosis, and coal workers’ pneumoconiosis (commonly referred to as CWP or black lung). As their names imply, they are caused by inhalation of  asbestos fibers,   silica dust , and coal mine dust. Typically, these three diseases take many years to develop and be manifested, although in some cases – silicosis, particularly – rapidly progressive forms can occur after only short periods of intense exposure. When severe, the diseases often lead to lung impairment, disability, and premature death. From a public health perspective, these conditions are entirely man-made, and can be avoided through appropriate dust control (CDC, 2017). The Respiratory Health Division within NIOSH published the first Work-Related Lung Disease (WoRLD) Surveillance Report in 1991 ( http://www.cdc.gov/niosh/docs/91-113/ ). This report presents data for asbestosis, coal workers’ pneumoconiosis, silicosis, byssinosis, exposure to cotton dust, hypersensitivity...

M5.4 Blog about your Consumer Confidence Reports (CCR) and water quality

Answer the following questions: What is the source of your drinking water?   Where does your water ORIGINATE?  (It is treated at a water treatment plant, but what watershed or aquifer is the sources of the water?) The Source is Surface Water, interestingly Sacramento is known as river city because with the Sacramento community and  all or parts of numerous watersheds including the Cosumnes, lower Mokelumne and Yuba rivers, as well as the Sacramento-San Joaquin Delta. These rivers provide the region with much of its surface water. What chemicals were found in your water that were higher than expected  1 chemical was detected under the EPA's Unregulated Contaminant Monitoring Rule (UCMR 3) program in 2013 to 2015, for which annual utility averages exceeded a health guideline established by a federal or state public health authority; radiological contaminants detected between 2010 and 2015. Chromium (hexavalent) is a carcinogen that commonly contami...
