Formaldehyde, an economically important chemical, is classified as a human carcinogen that causes nasopharyngeal cancer and probably leukemia. As China is the largest producer and consumer of formaldehyde in the world, the Chinese population is potentially at increased risk for cancer and other associated health effects. In this paper we review formaldehyde production, consumption, exposure, an...

Great attention has been paid to volatile toxic aldehydes like formaldehyde in aquatic products. In order to investigate content of formaldehyde in squid and squid products, a high-performance liquid chromatography (HPLC) method was developed for determination of formaldehyde. Based on steam distillation and 2,4-dinitrophenylhydrazine derivatization, formaldehyde was analysis by HPLC using ODS-...

This work studied the feasibility of using a solid phase microextraction (SPME) fiber for sampling and analysis of gaseous formaldehyde as well as particulate-bound formaldehyde from burning Chinese incense. The SPME fiber with PDMS/DVB coating were partially coated with o-(2,3,4,5,6-pentafluorobenzyl)-hydroxylamine hydrochloride (PFBHA), and used for sampling formaldehyde. The sampling rate fo...

OBJECTIVE Asthma is a complex pulmonary inflammatory disease characterized by the hyper-responsiveness, remodeling and inflammation of airways. Formaldehyde is a common indoor air pollutant that can cause asthma in people experiencing long-term exposure. The irritant effect and adjuvant effect are the two possible pathways of formaldehyde promoted asthma. METHODOLOGY/PRINCIPAL FINDINGS To exp...

there are adequate sources for wood adhesives, but scarcity of oil resources can affect the cost and future availability of oil based resins. for avoiding of this process, seeking for feasibility of replacement of these oil feedstocks is necessary. in present work, thermal behavior of urea formaldehyde resin modified by furfural was investigated. the thermo-gravimetry was used for this purpose,...

310 There are few reports of spontaneous ocular changes in laboratory rabbits (1), which when detected may complicate interpretation of ocular results in toxicity testing. The corneal changes that have been described in this species include anterior corneal dystrophy in American Dutch belted rabbits (2) and corneal epithelial dystrophy in New Zealand White (NZW) rabbits (3, 4). In addition, die...

BACKGROUND Formaldehyde levels were measured in 80 houses in the Latrobe Valley, Victoria, Australia. An association between exposure to formaldehyde and sensitization to common aeroallergens has been suggested from animal trials, but no epidemiologic studies have tested this hypothesis. METHODS A total of 148 children 7-14 years of age were included in the study, 53 of whom were asthmatic. F...
