纤维板中气味物质的化学组成、气味特征和风险值分析
Chemical composition,odor characterization and risk value analysis of odor compounds from fiberboards
摘要
Abstract
In order to clarify the treatment target for high-risk and pungent odor substances,the odor threshold(OT)and the lowest concentration of interest(LCI)data were measured and collected,and the odor activity value(OAV)and risk value(R)were calculated and evaluated,based on the systematic analysis of odor substances in fiberboards.The results showed that benzene series,terpenes,acetic acid,hexaldehydes and other small molecules were the most odor substances released in fiberboards.Although acetic acid(strong,pungent,similar smell to vinegar),propionic acid(spicy vinegar odor),styrene(pungent,similar smell to rubber),p-,m-xylene(irritating aromatic odor),1-butanol(alcohol spicy odor),o-xylene(irritating aromatic odor),benzaldehyde(bitter almond odor),and furfural(similar smell to benzaldehyde)had irritating odor,the main odor substances(OAV＞1)werealdehydes such as hexanal,nonanal,pentanal,and heptanal,and terpenes such as longifolene and α-pinene.The reduction of aldehydes and terpenes was the main way to reduce the pungent odor of fiberboards.The risk value of odor substances was related to both the amount of release and the LCI value.Although fiberboards contained low and medium toxic substances such as 2-methylnaphthalene and xylene,the risk values of these substances were far less than 1.关键词
