Investigation of Formaldehyde Concentration in the Air of an Anatomy Hall and Its Relationship with Environmental Factors
Introduction and purpose: Formaldehyde is used as a disinfectant and preservative for preserving the mummy’s body. The compound is classified by the International Agency for Research on Cancer in the Human Cancer Group. This study aimed to investigate the rate of exposure to formaldehyde vapors in an anatomy hall and its relationship with environmental factors. Methods: This descriptive study ...
متن کاملEfficacy of a detector tube method in formaldehyde measurement.
In order to determine the efficacy of a detector tube method in formaldehyde (HCHO) measurement, we performed a chamber experiment and a field study. The experiment clearly showed that the value obtained by the detector tube method was significantly correlated to that obtained using an active-DNPH method, and was not influenced by the coexistence of toluene, xylene or carbon monoxide, but was b...
متن کاملInvestigating Indoor Radon Concentration Using CR-39 Detector; a Case Study of Gachin Dwellings in Hormozgan
Introduction: Radon is a colorless inert gas which decay products are the main component of natural radioactive elements that are naturally produced in under layers of earth crust by decay of radium and uranium. It enters through buildings via gaps and cracks. Radon gas decay products like alpha particle can increase the incidence of lung cancer in human. Since every person sp...
متن کاملDetermination of organophosphate triesters in indoor air
In this thesis methods concerning sampling and analysis of organophosphorus triesters in indoor environments are investigated. Organophosphate esters are widely used as plasticizers and flame-retardants in plastic materials, which in turn are extensively used in all indoor environments. The organophosphates are ubiquitous indoor pollutants and humans will consequently be exposed to them. Some o...
متن کاملEvaluation of a passive air sampler for measuring indoor formaldehyde.
A passive air sampler, using 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole, was evaluated for the determination of formaldehyde in indoor environments. Chromatography paper cleaned using a 3% hydrogen peroxide solution was experimentally determined as being the optimum absorption filter for the collection of formaldehyde (0.05 microg cm(-2) formaldehyde). From a linear-regression analysis betwe...
