TECHNICAL REPORT
This journal article advocates for transitioning the dry cleaning industry away from perchloroethylene (PERC) and describes the local efforts of the Haz Waste Program to switch dry cleaners to professional wet cleaning. [Project: Drycleaning]
TECHNICAL REPORT
This report describes the pilot program established by the Haz Waste Program to transition perchloroethylene (PERC) dry cleaners to professional wet cleaning (PWC). [Project: Drycleaning]
TECHNICAL REPORT
We evaluated the relative toxicity of products used by shops before and after they switched from PERC to professional wet cleaning. [Project: Drycleaning]
TECHNICAL REPORT
We evaluated three new high-flashpoint hydrocarbon dry cleaning solvents: Optima DCFTM, SenseneTM, and Intense®. All three solvents are likely safer alternatives to perchloroethylene (PERC) for dry cleaning. [Project: Drycleaning]
TECHNICAL REPORT
We conducted a comprehensive evaluation of 3 high-flash point hydrocarbon dry cleaning solvents. They are complex mixtures of hydrocarbons. Benzene was not detected and they were not toxic to fish. [Project: Drycleaning]
TECHNICAL REPORT
This journal article describes exposures of dry cleaners to new solvents that are replacing perchloroethylene (PERC). [Project: Drycleaning]
TECHNICAL REPORT
We evaluated the toxicity of PERC dry cleaning solvent and found that this is the most toxic of the dry cleaning solvents tested in a fish bioassay (LC50 = 3.61 mg/L). [Project: Drycleaning]
TECHNICAL REPORT
We tested still bottoms from 4 PERC machines. The toxicity varied, likely because of differences in amount of PERC, detergents, spot cleaners, additives, and material extracted from fabrics. [Project: Drycleaning]
TECHNICAL REPORT
We tested still bottoms from 4 PERC machines. The toxicity varied, likely because of differences in amount of PERC, detergents, spot cleaners, additives, and material extracted from fabrics. [Project: Drycleaning]
TECHNICAL REPORT
This journal article describes the most frequently-used alternative dry cleaning process to perchloroethylene (PERC). [Project: Drycleaning]
TECHNICAL REPORT
We evaluated workplace exposures to SolvonK4 and DF2000 by collecting air samples and evaluating skin exposures. Air exposures were below permissible limits and there was limited skin contact. [Project: Drycleaning]
TECHNICAL REPORT
Evaluation of DF2000(TM) Dry Cleaning Solvent in an Acute Fish Toxicity Test. [Project: Drycleaning]
TECHNICAL REPORT
We evaluated the toxicity of still bottoms generated by alternative dry cleaning solvents. Still bottoms contained detergents, solvents, and other substances that were toxic to fish. [Project: Drycleaning]
TECHNICAL REPORT
We evaluated the toxicity of Solvon K4 dry cleaning solvent; the LC50 was 45.7 mg/L. Therefore, unused or off-specification Solvon K4 product that requires disposal would designate as Dangerous Waste. [Project: Drycleaning]
TECHNICAL REPORT
We evaluated 16 shops that used hydrocarbon or Solvon K4 and found that efforts are needed to replace hazardous spot cleaning chemicals and ensure that wastes are disposed of properly. [Project: Drycleaning]
TECHNICAL REPORT
This journal article describes our needs assessment of the local dry cleaning industry. [Project: Drycleaning]
TECHNICAL REPORT
We evaluated several vapor leak detectors for use by dry cleaners. Three detectors conformed to required technical specifications. [Project: Drycleaning]
TECHNICAL REPORT
We conducted interviews, site visits, and a survey. Dry cleaning is dominated by small, Korean-owned, family businesses. Many faced several challenges and recommendations were provided. [Project: Drycleaning]
