Title
An Analysis of Lead Surface CrossContamination in a Metal Assay Lab: An Analysis of Inorganic Lead Surface Contamination and Em,Used
Delivery time: 8-12 business days (International)
An industrial hygiene assessment was performed in order to analyze surface crosscontamination between lead and nonlead working areas of an assay laboratory. Employee contamination was assessed to determine if lead was transported to the different areas of the assay laboratory. The employees work clothes and hands were examined to further assess crosscontamination and the potential for inorganic lead ingestion. To characterize area crosscontamination, 52 surface wipe samples were collected in 26 areas of the laboratory. In addition, 36 microvacuum samples taken from employees clothes were collected before and after work shifts. Fourteen hands wipe samples were also collected to characterize employees skin contamination. Ghost wipes were used for the collection of all surface wipes as well as employees hand wipe samples. Nonparametric statistics were used to determine significant differences in employees lead concentration build up and surface area lead crosscontamination. A statistically significant difference (p>0.05) in surface lead concentration was found, indicating that lead crosscontamination was evident.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
