“…Industrial resins used in manufacturing of polymeric products, such as paints and adhesives, are pollution sources as well (Fjällström et al, 2003). Indoors, carbonyls can be directly released from wooden furniture, building materials, and household products and formed through reactions between indoor volatile organic compounds (VOCs) (e.g., alkenes) and oxidants (e.g., O 3 ) (Morrison et al, 2002;Clarisse, 2003;Poppendieck et al, 2007). Formaldehyde and acetaldehyde are two abundant pollutants in residential units, offices, and schools because of their existences in wooden materials used for manufacturing decoration and furniture (Yu and Brump, 1999;Yu and Kim, 2011a, b).…”

Risk assessment for indoor formaldehyde and other carbonyls was investigated at an university in Xi'an, Shaanxi, China. Eight representative locations, including six indoor workplaces and two residential units of staff apartments and a student dormitory, were chosen. The indoor pollution origins were identified according to the variability in molar composition and correlation analysis for the target species. Environmental tobacco smoke (ETS), cooking activities, and office technologies such as printers and copiers can produce different degrees of carbonyls in the workplace. A one-year demonstration study conducted in a apartment showed significance of the off-gases from lacquers and new wooden furniture. The concentrations of formaldehyde and acetaldehyde in the most sampling locations were above the recommended exposure limits, reflecting a potential health risk to workers and occupants. Chronic daily intake (CDI) and lifetime cancer hazard risk (R) were calculated to assess the carcinogenic risks of chronic exposure to the carbonyls. The R values for formaldehyde exceeded the alarm level of 1 × 10 -6 in all sampled workplaces, but lower R values were associated with acetaldehyde. The results indicate that exposure of formaldehyde is a critical occupational health and safety concern. In addition, high risks associated with formaldehyde were also measured in the staff apartment, suggesting that the refurbishing materials and wooden furniture can potentially cause health impacts to occupants. The findings are informative to be referred in establishment of indoor air quality guidelines in China.

“…Marchand et al (2006) investigated the concentrations of carbonyls in 162 France homes related to the concentration of aldehyde, and found significant positive correlation between the presences of new coatings and formaldehyde concentrations. Clarisse et al (2003) also mentioned the influence of new coverings of walls and ground on the aldehydes concentrations at homes in France.…”

Concentrations of carbonyl compounds (formaldehyde, acetaldehyde, acrolein and acetone) and BTEX (benzene, toluene and xylenes) were monitored at 128 residential homes (255) The concentrations of all species during the investigation period were below the Chinese guideline values. Based on the measured concentrations, a receptor model (PMF; positive matrix factorization) coupled with the source information was applied to identify the major emission sources. The results showed that four major sources were identified by the PMF method, including (1) outdoor incursion factors, (2) emissions from building materials and paint solvent, (3) emissions from particle board and plywood flooring and (4) emissions from household cleaning chemicals. Our results also reveal that the health risks due to exposure to formaldehyde and benzene for Beijing residents were greater during this period than those for people living in Guangzhou and Hangzhou, China.

“…The widespread use of aldehyde-based resins and construction materials in modern building interiors, coupled with lower levels of indoor ventilation, can result in elevated concentrations of ACA. [1] ACA can also result from incomplete combustion of fuel oxygenates, such as ethanol and corresponding ethers (diethyl ether and ethyl tert-butyl ether), [2,3] which is becoming increasingly important as more governments mandate the use of ethanol-petrol blends. ACA is a potent carcinogen and prolonged, low-level (0.5 ppm) exposure has been shown to induce a variety of detrimental health effects.…”

The influence of Cu on various metal oxide supports was investigated for the catalytic oxidation of acetaldehyde (ACA). The activity of the catalysts towards ACA conversion and the CO2 yield decrease in the order: Cu/CeO2>Cu/TiO2≈Cu/ZrO2> Cu/Al2O3>Cu/SiO2. Spontaneous adsorptive conversion of ACA to surface carboxylates, such as bridging and bidentate acetates, was detected over the basic supports CeO2, TiO2, and ZrO2. Detailed temperature‐programmed studies found the high activity of Cu/CeO2 to stem mainly from the intrinsically high activity of the CeO2 support. In contrast, similar studies on Cu/TiO2 demonstrated the activity improvements imparted by Cu were predominantly additive. Despite the difference in origin of ACA oxidation activity over Cu/CeO2 and Cu/TiO2, the overall concerted effects of basicity‐induced carboxylate formation and availability of surface oxygen were thought to be overriding factors crucial in the overall catalytic reactivity.
