“…Previous studies have used other prevalent volatile organic compounds (VOC) such as acetaldehyde, ethanol, beta-myrcene, acetone, beta-pinene, limonene, and alpha-pinene in at least 40% of the products. Similarly, ethanol, acetaldehyde, alpha pinene, phenoxyethanol, limonene, and ethyl butyrate were the six most prevalent VOC's in building materials detected by GC/MS [21, 22]. These compounds, however, were not discussed and monitored in the present study.…”

Air fresheners contain various chemicals that may or may not be harmful to human health and the environment. These products are widely used in different settings such as homes, schools, offices, and hospitals with ignorance of their real ingredients and their relative health effects. Thus, this preliminary study was carried out to identify the presence of different compounds in spray air fresheners that were not disclosed on the product's label. Four different brands of spray air fresheners were selected randomly from a local store, in which two were of mid-to-high cost and the remaining two of low cost. The samples were analyzed using gas chromatography/mass spectrometry headspace, in which single components of the samples were identified by the mass spectrometry detector. The results were shown as a chromatogram of several peaks, each representing different compounds. The chemicals found in the samples include; lilial, galaxolide, benzenemethanol, musk ketone, butylated hydroxytoluene, and linalool. These chemicals may cause irritation and other health problems. However, none of them were revealed on the product's label. The study concludes that air fresheners need to be free of any toxic or harmful chemicals and include natural ingredients instead.

“…Styrene is a component of SBR, the most common binding component used in latex carpet backing and multipurpose carpet adhesives. Studies of VOC emissions from furnishing and building materials have reported styrene in carpet glue and other adhesives, rubber and plastic products, rigid foam insulation, carpets, resilient floor coverings, and printed materials (California Environmental Protection Agency (Cal EPA), 1999;Hodgson 2003;Kataoka et al 2012;Katsoyiannis, Leva, and Kotzias 2008;U.S. EPA, 1993a;Wallace et al 1987c;Wolkoff 1995;Willem and Singer 2010;Yu and Crump 1998;Zellweger et al 1997).…”

The potential chronic health risks of occupational and environmental exposure to styrene were evaluated to update health hazard and exposure information developed since the Harvard Center for Risk Analysis risk assessment for styrene was performed in 2002. The updated hazard assessment of styrene's health effects indicates human cancers and ototoxicity remain potential concerns. However, mechanistic research on mouse lung tumors demonstrates these tumors are mouse-specific and of low relevance to human cancer risk. The updated toxicity database supports toxicity reference levels of 20 ppm (equates to 400 mg urinary metabolites mandelic acid + phenylglyoxylic acid/g creatinine) for worker inhalation exposure and 3.7 ppm and 2.5 mg/kg bw/day, respectively, for general population inhalation and oral exposure. No cancer risk value estimates are proposed given the established lack of relevance of mouse lung tumors and inconsistent epidemiology evidence. The updated exposure assessment supports inhalation and ingestion routes as important. The updated risk assessment found estimated risks within acceptable ranges for all age groups of the general population and workers with occupational exposures in non-fiber-reinforced polymer composites industries and fiber-reinforced polymer composites (FRP) workers using closedmold operations or open-mold operations with respiratory protection. Only FRP workers using open-mold operations not using respiratory protection have risk exceedances for styrene and should be considered for risk management measures. In addition, given the reported interaction of styrene exposure with noise, noise reduction to sustain levels below 85 dB(A) needs be in place.

“…In the last years, devices that can measure and monitoring chemical-, physical-and biological-changes in the environment, with low cost, compact size, and low-power consumption have been developed under the form of sensors [4,5]. Sensors are devices that provides an output signal usable in response to a specific measure, such as observable chemical reactions between certain materials [6].…”

Indoor air pollution can induce adverse health effects on building occupants and pose a significant role in health worldwide. To avoid such effects, it is extremely important to monitor and control common indoor pollutants such as CO2, VOCs and relative humidity. Therefore, this work focuses on recent advances in the field of graphene-based gas sensors, emphasizing the use of modified graphene that broadly expands the range of nanomaterials sensors. Graphene films were grown on copper by chemical vapor deposition (CVD) and transferred to arbitrary substrates. After synthesis, the samples were functionalized with Al2O3 by ALD and characterized by a large set of experimental techniques such as XPS, Raman and SEM. The results demonstrated that graphene was successfully synthesized and transferred to SiO2, glass and polymer. As a proof-of-concept, ALD of Al2O3 was performed on the graphene surface to produce a graphene/metal oxide nanostructure towards the development of nanocomposites for gas sensing. From this perspective, a laboratory prototype device based in measuring the electrical properties of the graphene sample as a function of the gas absorption is under development.
