Airborne arsenic and urinary excretion of arsenic metabolites during boiler cleaning operations in a Slovak coal-fired power plant.

Little information is available on the relationship between occupational exposure to inorganic arsenic in coal fly ash and urinary excretion of arsenic metabolites. This study ws undertaken in a coal-fired power plant in Slovakia during a routine maintenance outage. Arsenic was measured in the breathing zone of workers during 5 consecutive workdays, and urine samples were obtained for analysis ...

Effective Data Cleaning with Continuous Evaluation

Enterprises have been acquiring large amounts of data from a variety of sources to build their own “Data Lakes”, with the goal of enriching their data asset and enabling richer and more informed analytics. The pace of the acquisition and the variety of the data sources make it impossible to clean this data as it arrives. This new reality has made data cleaning a continuous process and a part of...

HOW MUCH CLEANING IS ENOUGH? AN EVALUATION OF ALTERNATIVE POST-LEAD HAZARD INTERVENTION CLEANING PROCEDURES By:

This study evaluated and compared two procedures to clean lead dust and debris after lead hazard control activities were completed in housing with lead-based paint hazards. 1995 Federal guidelines prepared by the U.S. Department of Housing and Urban Development for the control of lead-based paint hazards in housing strongly recommend that after lead hazard control interventions all walls, ceili...

Coal tars and coal tar pitches.

Numerous studies, mostly case reports, have found that occupational exposure to coal tars or coal-tar pitches (coal-tar distillates) is associated with skin cancer, including scrotal cancer; workers in these studies have included patent-fuel (coal-briquette) workers, pitch loaders, workers in electrical trades, and optical-lens polishers (IARC 1985, 1987). A 1946 study in the United Kingdom fou...
