Microbiological Safety Evaluation of an Industrial Refuse Incinerator

Arsenic burden survey among refuse incinerator workers.

BACKGROUND Incinerator workers are not considered to have arsenic overexposure although they have the risk of overexposure to other heavy metals. AIM To examine the relationship between arsenic burden and risk of occupational exposure in employees working at a municipal refuse incinerator by determining the concentrations of arsenic in the blood and urine. SETTINGS AND DESIGN The workers we...

Evaluation of laminar flow microbiological safety cabinets.

The microbiological control efficiency of two class 100 laminar down-flow hoods was determined by using aerosols of Bacillus subtilis var. niger spores. The first unit challenged utilized a slanted eyelid to partially enclose the front work opening. This hood showed nearly perfect control of ambient organisms in the work area. It also gave a 10(6) or greater drop in the number of organisms pass...

Microbiological safety of water.

Significant advances in water treatment over the last century have resulted in massive improvements in the microbiological safety of public drinking water supplies in the UK and the developed countries. Incidences of illness due to poor treatment or post-treatment contamination are rare, but when they occur tend to attract considerable media attention. A well managed water treatment works and s...

Risk of soft tissue sarcomas and residence in the neighbourhood of an incinerator of industrial wastes.

AIMS To investigate the association between occurrence of soft tissue sarcomas (STS) in Mantua and residence near an incinerator of industrial wastes. METHODS Cases were subjects with histologically confirmed primary malignant STS diagnosed 1989-98 in the population resident in Mantua and in the three neighbouring municipalities. Controls were randomly extracted from population registries, ma...
