“…Some VOCs have been linked to acute and/or chronic health effects, such as headaches, respiratory tract and eye irritation, liver and kidney damage, and some are known carcinogens ( 23 , 24 ). Low-VOC paint can contain up to 50 g/L of VOCs( 25 ); the VOCs commonly found in WBP are ethylene glycol, texanol, and propylene glycols( 26 – 29 ).…”

Obtaining valid, reliable quantitative exposure data can be a significant challenge for industrial hygienists, exposure scientists, and other health science professionals. In this proof-of-concept study, a robotic platform was programmed to perform a simple task as a plausible alternative to human subjects in exposure studies for generating exposure data. The use of robots offers several advantages over the use of humans. Research can be completed more efficiently and there is no need to recruit, screen, or train volunteers. In addition, robots can perform tasks repeatedly without getting tired allowing for collection of an unlimited number of measurements using different chemicals to assess exposure impacts from formulation changes and new product development. The use of robots also eliminates concerns with intentional human exposures while removing health research ethics review requirements which are time consuming. In this study, a humanoid robot was programmed to paint drywall, while volatile organic compounds were measured in air for comparison to model estimates. The measured air concentrations generally agreed with more advanced exposure model estimates. These findings suggest that robots have potential as a methodology for generating exposure measurements relevant to human activities, but without using human subjects.

“…In this study, VOCs in water-based paints could be quantified by a simple method using only liquidliquid distribution. There have been studies on the analysis of VOCs in water-based paints 9,13,14) but no studies on the simultaneous analysis of 12 VOCs that differ in polarity from polar substances to nonpolar substances such as TMPDIB by GC/MS. Therefore, this method is applicable to the measurement of VOCs used in water-based paints.…”

We developed an analytical method for volatile organic compounds (VOCs) used as film-forming agents or anti-freeze agents in water-based paints by flame ionization detection (FID-GC) and gas chromatography mass spectrometry (GC/MS). Twelve VOC components were separated using 2 types of column that differ in polarity. In addition, a pretreatment method by ethyl acetate-water partition was evaluated, and a survey of the use of VOCs in commercially available water-based paints was performed. For indoor paints, the anti-VOC measures included changes from VOC solvents to semi-VOC (SVOC) solvents such as those from 2,2,4-trimethyl-1,3-pentanediolmonoisobutyrate (TMPMIB) to 2,2,4-trimethyl-1,3-pentanediol diisobutyrate and from ethylene glycol (EG) to triethylene glycol. However, in multipurpose paints for both indoor and outdoor use, VOCs such as EG, TMPMIB, diethyleneglycol dibutyl ether, and diethyleneglycol monobutyl ether were detected. Since these products may be also used for indoor painting, indications of VOC components and caution for use on products are necessary.

Perception of odor can figure prominently in complaints about indoor air,yet identification of the responsible compound(s) is often difficult. For example, paint emissions contain a variety of odorous volatile organic compounds (VOCs) which maytrigger reports of irritation and upper respiratory health effects. Texanol ester alcohol (2,2,4-trimethyl-1,3-pentanediol monoisobutyrate), a paint coalescing agent, is frequently associated with the "persistent, characteristic odor" of water-based paint. To evaluate the sensory impact of Texanol, naive (unfamiliar with paint constituents) and experienced (familiar with paint constituents) subjects evaluated the odor properties of paints with and without Texanol. VOC emissions from neat paint and paint applied to gypsum wallboard were collected via solid-phase microextraction and analyzed by gas chromatography/ mass spectrometry and gas chromatography/olfactometry. Regardless of subjects' prior experience, aromatic hydrocarbons and oxygenated compounds, introduced from other paint additives and not Texanol, were most commonly associated with paint odor. However, quantitative sensory techniques demonstrated that addition of Texanol to paints led to an overall increase in the perceived intensity of the coating. The combined use of these techniques proved to be an effective methodology for analyzing the structure of paint volatiles and their sensory properties and holds promise for solving many odorous indoor air problems.
