“…Research carried out by Kim and Kim (Kim and Kim, 2005) proved that the addition of melamine-formaldehyde resin to urea-formaldehyde resin dramatically reduced the level of formaldehyde emission from wood fiber made from Korean pine (Pinus densiflora ). Urea-formaldehyde resin produces approximately 23% more emissions of formaldehyde than melamine-urea-formaldehyde resin (Silva et al 2015).…”

Adhesives are substances that increase the surface adhesion of bonded items. Unfortunately, they also emit volatile organic compounds (VOCs) which negatively impact upon human and animal health. VOCs have carcinogenic and mutagenic properties and can cause migraines, irritation to the eyes, nasal passages, mouth, and lungs, and respiratory problems. Wastewater from adhesive production is characterized by high levels of pollutants and contains high concentrations of compounds including formaldehyde that are toxic to water biocenoses. Moreover, its purification causes many problems and requires the application of specific methods. This review presents data concerning the toxicity and ecotoxicity of selected adhesives components. VOC emission rates from adhesives and wooden construction elements with adhesives are also discussed and assessed. Current knowledge on the treatment methods for wastewater containing adhesive components is reviewed. Finally, the treatment and disposal methods for solid wooden waste containing adhesives are also analyzed and discussed.

“…The standard additions method has been widely used to detect a variety of analytes in complex media, such as biological fluids, where interference in analyte signal can cause inaccuracies [37][38][39][40][41][42]. The method used here is similar to the Gran plot standard additions method used previously to determine unknown parameters, such as the slope and y-intercept of a calibration curve for the detection and monitoring of ions [43][44][45][46].…”

Sol-gel encapsulation has been used as the basis for detecting cortisol by an immunoassay approach. Previous research showed that antibodies immobilized in the pores of a sol-gel derived silica were able to bind cortisol and be used as an immunosensor. However, this approach was not effective when measuring cortisol levels in human serum because of interference from other fluorescence sources. The present paper describes a protocol which overcomes these limitations and enables sol-gel immunoassays to effectively measure cortisol in human serum over the physiological range of cortisol blood concentrations in an adult (2-28 lg/dL). The method involves a standard additions approach in which various amounts of cortisol are added to the serum. The cortisol concentration values obtained with our sol-gel immunoassay were typically within 10% of the values obtained by traditional analytical methods. The protocol presented here represents a significant contribution to sol-gel sensing and immunoassays in particular, because of the ability to detect an analyte in human serum. In addition, this work reports the first comparison between results from a sol-gel immunosensor and an alternative immuno-binding method for analyte detection.

“…The most common catalysts are the latent (ammonium sulphate, ammonium chloride and ammonium nitrate) [41][42][43][44][45]. Latent catalysts, in the presence of water (which promotes dissociation), react with formaldehyde forming an acid, hexamine and water (equations 1.1 to 1.3).…”

“…Many authors have tried to relate formaldehyde emissions measured by different methods [37][38][39][40], but the relations are influenced by other variables, such as resin type, type of wood-based panels, thickness or manufacturing conditions. Salem et al [41] and Kim and Kim [42] studied formaldehyde emission from different types of formaldehyde based resins. Salem et al [43] showed that the manufacturing variables interfere significantly with formaldehyde emissions and the correlations between methods to assess different products were not possible.…”
