We have experimentally quantified exposure to dichloromethane during non-professional paint stripping and validated the mathematical paint exposure model of van Veen et al. (1999). The model innovates the prediction of the dichloromethane evaporation rate and room concentration by accounting for transport in the paint stripper matrix. The experiments show that peak concentrations range from 600 to 1600 mg/m3, increasing to 2000 mg/m3 when direct sun radiation increases evaporation. A naive… 
Evaluation of three physiologically based pharmacokinetic (PBPK) modeling tools for emergency risk assessment after acute dichloromethane exposure.
The Bos Mumtaz and Jongeneelen PBPK models were able to simulate experimental DCM blood concentrations reasonably well and the Bos model appears to be useful for calculating HbCO concentrations in emergency risk assessment.
TSCA Work Plan Chemical Risk Assessment Methylene Chloride: Paint Stripping Use
This risk assessment addresses DCM, a volatile organic compound (VOC) that is used as a solvent in a wide range of industrial, commercial and consumer use applications, such as adhesives, paint
Detection of dichloromethane with a bioluminescent (lux) bacterial bioreporter
This bioreporter, Methylobacterium extorquens DCMlux, was engineered to contain a bioluminescent luxCDABE gene cassette derived from Photorhabdus luminescens fused downstream to the dcm dehalogenase operon, which causes the organism to generate visible light when exposed to DCM.
Housing Characteristics and Indoor Concentrations of Selected Volatile Organic Compounds (VOCs) in Quebec City, Canada
Concentrations of 26 volatile organic compounds (VOCs) were measured continuously for 7 days during winter in 96 homes in Quebec City, Canada. Characteristics of the houses and activities of the
Evaluation and further development of EASE model 2.0.
A critical assessment of the utility and performance of the EASE model is provided, and on the basis of this review, recommendations for the structure of a revised model are outlined.
Photoinitiators enhanced 1,2-dichloropropane-induced cytotoxicity in human normal embryonic lung fibroblasts cells in vitro
The combined effects of DCP and photoinitiators used in printing on normal human embryonic lung fibroblasts may increase the risk of respiratory diseases.
Household hazardous waste : disposal to landfill as a pathway for environmental pollution
Apprehension relating to chemicals used widely within the home has led to concern that the disposal of such hazardous substances into the municipal waste stream (MSW) may pose risks to the
Hazardous Components of Household Waste
Household hazardous waste (HHW) includes waste containing hazardous substances originating from domestic sources. HHW has attracted attention recently because of the steadily increasing levels of
Current Awareness in Clinical Toxicology
Although a raised TnI was associated with a markedly increased risk of death or orthotopic liver transplant, this was primarily seen in the context of MOF (SOFA score p = 0.05) on univariate analysis.
Control strategies for indoor environment quality and energy efficiency—a review
The demand for better indoor environment has led to a wide use of heating, ventilating and air conditioning (HVAC) systems. However, this demanding cannot be sustained without a strategy to reduce


Indoor air exposure to volatile compounds emitted by paints: experiment and model
Modelling the evaporation of organic solvents from paints and the resulting indoor concentrations were in agreement, although the timing of the concentration peak appeared difficult to predict.
Dichloromethane levels in air after application of paint removers
The NIOSH charcoal tube method and a glass bulb grab sampling method were used to determine dichloromethane levels in the air of a room used for testing six paint removers. Dichloromethane and
Modeling methylene chloride exposure-reduction options for home paint-stripper users
Results indicate that the effectiveness of behavioral interventions depends strongly on characteristics of the room, and the greatest simple reduction in exposure is achieved by using an exhaust fan in addition to opening windows and doors.
High exposures to organic solvents among graffiti removers
This study demonstrates that old knowledge about work harzards is not automatically transferred to new professions, and that the public is also exposed as the job is performed during daytime in underground stations, where bystanders may be exposed to high concentrations of organic solvent vapours.
Exposure to Methylene Chloride from Controlled Use of a Paint Remover in Residences
A recent laboratory investigation characterized personal exposures to methylene chloride (CH/sub 2/Cl/sub 2/) for simulated typical uses of paint removers and aerosol finishes containing CH/sub
Source characterization and personal exposure to methylene chloride from consumer products
A recently completed bioassay, which found methylene chloride (CH/sub 2/Cl/sub 2/) to be an animal carcinogen, has increased the concern about consumer exposure to this chemical. To provide
Methylene chloride intoxication in a furniture refinisher. A comparison of exposure estimates utilizing workplace air sampling and blood carboxyhemoglobin measurements.
A 35-year-old furniture refinisher came to the occupational medicine clinic with complaints of upper respiratory irritation, fatigue, and lightheadedness occurring on a daily basis after using a methylene chloride-containing paint stripper, indicating the potential usefulness of COHb monitoring in estimating airborne exposure levels.

Current safety practices in small-scale furniture-stripping shops may be inadequate to keep methylene chloride exposure levels in compliance with latest recommendations, and serious or fatal overexposure can occur.
Derivation of an occupational exposure limit (OEL) for methylene chloride based on acute CNS effects and relative potency analysis.
An alternative safety assessment for methylene chloride is presented, based on an acute human lowest-observed-adverse-effect level (LOAEL) of 200 ppm for subtle central nervous system (CNS) depression, which is a defensible alternative to to the OSHA risk assessment and should positively contribute to the debate regarding the appropriate basis and value for aethylene chloride PEL.
Emissions of volatile organic compounds from building materials and consumer products
Abstract EPA's TEAM Study of personal exposure to volatile organic compounds (VOC) in air and drinking water of 650 residents of seven U.S. cities resulted in the identification of a number of
