Facts About Mold: An AIHA Perspective for IEQ Investigators, Physicians, and Engineers

The U.S. Centers for Disease Control and Prevention (CDC), the Institute of Medicine of the U.S. National Academy of Sciences, the American Academy of Allergy, Asthma & Immunology (AAAAI), Health Canada, and the World Health Organization all agree that living or working in a building with mold-damaged building materials results in increased risk of respiratory diseases such as asthma. The American Industrial Hygiene Association (AIHA) has worked to translate the advice from these public health and medical authorities into state-of-the-art inspection and sampling protocols. These protocols are captured in AIHA’s Recognition, Evaluation and Control of Indoor Mold publication, also known as the Green Book. These methods are suitable for assessing visible and hidden mold contamination and developing a mold remediation plan

Electronic Cigarettes in the Indoor Environment

E-cigarettes should be considered a source of volatile organic compounds (VOCs) and particulates in the indoor environment that have not been thoroughly characterized or evaluated for safety. --NIOS

Presentation discusses the following research objectives: 1. Address student workers’ concern regarding respiratory health 2. Characterize aerosol and VOC exposures during printing operations 3. Identify primary sources of exposure using NIOSH EVADE software, spatial analysi

Exposure Implications of Electronic Cigarette Surface Contamination

Retention of nicotine on porous, hydrophilic surfaces can be long enough to allow reaction with ambient gases to form TSNAs (tobacco specific nitrosamines). Potential risk for third-hand exposure over time appears to be low, but should be verified by longer term studies. Use of ECs (electronic cigarettes) should be consistent with traditional cigarette smoking policies

Formaldehyde: Is It a Problem in My Home?

This guide is intended to help you decide if you want to investigate a possible indoor formaldehyde problem that you suspect is attributable to laminate flooring

A Review of Studies of Ventilation and Indoor Air Quality in New Homes and Impacts of Environmental Factors on Formaldehyde Emission Rates From Composite Wood Products

While increasing outdoor air ventilation rates does reduce the indoor concentrations of air contaminants with indoor sources, the actual reductions in concentrations can differ significantly from those calculated with the assumption of a constant indoor emission rate. The ratio of actual to predicted concentration reductions for the low to high outdoor air ventilation modes ranged from 0.59 for formaldehyde to 1.37 for benzaldehyde. Increases in emission rates for compounds such as formaldehyde are consistent with mass transfer theory for emissions from materials such as composite wood where mass transfer is limited by gas-phase diffusion across the boundary layer. Decreases in emission rates of compounds such as d-limonene were surprising and may be the result of residual emissions of cleaning chemicals which were used by the occupants prior to the tests
