Excellent Industrial Hygiene Blog

Each month we publish a newsletter titled IAQ Website of the Month.  The excerpt below was originally published in the April 2014 newsletter.

Each month I try to feature a website with broad appeal to our 4,000+ subscribers.  Although this month’s website has a more narrow focus and covers an advanced topic, I think you will thoroughly enjoy it.

The blog is titled, “Human Health Risk Assessment to Chemicals” and it is written by Mike Jayjock.  The blog is based on the principle that an occupational risk cannot be managed unless it is properly assessed.

Mr. Jayjock’s blog has a special focus on computer modeling to better assess risks.  For example, if you measure chemical exposures on a random day and the results are very close to exceeding a permissible exposure limit (PEL), what are the odds that the exposure will exceed the PEL on some other day?

Here are some blog posts that might interest you:

Lead Paint – An IAQA Tech Tip Video


Although the heavy metal “lead” can be found in many different products at varying concentrations, it’s presence in paint prior to 1978 poses the greatest impact on indoor air quality, even today. Learn about lead-based paint in this video, including its affect on health- especially of children.

Semi Volatile Organic Compounds – An IAQA Tech Tip Video


Semi volatile organic compounds (SVOCs) may not be as well known as more ordinary VOCs, but they include many pesticides and plasticizers. In this video you’ll learn that SVOCs are common, deleterious to health and difficult to measure.

Position Statements & White Papers

Each month we publish a newsletter titled IAQ Website of the Month.  The excerpt below was originally published in the March 2014 newsletter.

“Gray areas” seem to have a home in the field of indoor air quality. Pick any contentious topic and one could argue both sides with equal fervor. Where can you turn to get a balanced view?

One resource is the American Industrial Hygiene Association (AIHA).  They have developed over 30 position statements and white papers on a wide range of topics, many applicable to indoor air quality.

Position statements and white papers are typically developed by an AIHA technical committee and approved by their board of directors.  Although they may not hold as much weight as a consensus-based ANSI standard, they are to be highly regarded due to the stature and reputation of AIHA.

I thought the following documents might interest you:

Environmental Allergens

Each month we publish a newsletter titled IAQ Website of the Month.  The excerpt below was originally published in the February 2014 newsletter.

Sometimes I feel sorry for dust mites. How would you like it if your picture was used to sell vacuums, filters and carpet cleaning services? Does vacuuming and air cleaning even control dust mites?

This month’s featured website is an authoritative resource for all things related to environmental allergens.  The site is called Allergy Practice Parameters and comes from a joint task force of AAAAIACAAI.  The joint task force develops Practice Parameters, which are to be used by practicing physicians.  It can be time consuming to wade through all the new research and marketing propaganda to figure out the current state of the art.  The practice parameters act as a collective review of relevant and evidence-based information.

Currently there are four practice parameters on environmental allergy:

What I love about these practice parameters is that they have a scale for strength of evidence and strength of recommendation. Back to our question about vacuuming and air cleaning for dust mites. The following are found in the Dust Mite Allergy Practice Parameter:

  • Recommend regular vacuuming using cleaners that have high-efficiency particulate air (HEPA) filtration… [Recommendation: Strong]
  • HEPA filtration alone is of uncertain benefit for patients with mite allergy… [Recommendation: Weak]

I recommend you read the whole practice parameter to get the full context of these sound bites.

It’s Alive!

Each month we publish a newsletter titled IAQ Website of the Month.  The excerpt below was originally published in the November 2013 newsletter.

You might know that a grain of pollen is bigger than a mold spore, which is bigger than a bacterium, which in turn is bigger than a virus.  But have you ever seen them all side-by-side?

This month’s featured website, “Cells Alive”, includes animations and interactive tools to help you get a better perspective on things too small to see with the naked eye.

The best part of the website is the “How Big?” tool.  Zoom in to see the relative difference in size between a dust mite and a rhinovirus.

Other worthwhile pages on the site include:
