Biomonitoring for Occupational Exposure to Diisocyanates: A …
For this reason, the biomonitoring techniques used to monitor diisocyanates exposure investigate the presence of products of chemical degradation, such as diamines in urine, or products of metabolism, such as acetylated amines or protein adducts in urine or blood samples.
Biological monitoring for isocyanates - Oxford Academic
2007年9月1日 · Organic diisocyanates are a significant occupational health problem. They are respiratory and skin sensitizers and a major cause of occupational asthma in the UK [1]. The most common are hexamethylene diisocyanate (HDI), toluene diisocyanate (TDI), isopherone diisocyanate (IPDI) and methylene-diphenyl diisocyanate (MDI) in decreasing order of ...
Diisocyanates react with amines, alcohols, hydroxides and even water to form various compounds. Therefore, to assess real-time airborne concentrations of MDI or TDI, both direct and indirect air sampling methods typically involve the use of a paper tape or filter coated with a reagent that reacts with diisocyanates to form a stable derivative.

2020年7月1日 · Diisocyanates are a group of chemicals that are widely used in occupational settings. They are known to induce various health effects, including skin- and respiratory tract sensitization resulting in allergic dermatitis and asthma. Exposure to diisocyanates has been studied in the past decades by us …
Diisocyanates (2,4‐toluene‐, 2,6‐toluene‐, 4,4′‐methylene …
2012年1月31日 · For monitoring the short-term value, the air sample is drawn through the isocyanate sampling-set using a flow rate of 2 L/min over a time period of 15 min. The parameters which are important for the determination of the diisocyanate concentrations in air (sample volume, temperature, atmospheric pressure, and relative humidity) are documented in ...
