Results of a recent study conducted by a research team at the University
of Minnesota School of Public Health, Division of Environmental Health
Sciences suggest that most containers used for storage and
transportation of used fluorescent lamps to recycling centers do not
provide necessary levels of protection against mercury vapors emitted
from broken lamps.
The study, published in the March 2009
issue of the Journal of the Air & Waste Management Association,
found that of the five packages tested in the study, just one
configuration—consisting of a zip-closure plastic-foil laminate bag
layered between two cardboard boxes—minimized exposure levels below
acceptable occupational limits, as defined by state and federal
regulations and guidelines.
Based on the measurements of
mercury vapor from single broken fluorescent bulbs, it was determined
the need for additional research to quantify emissions from various
types of packaging. The results indicate that emissions from packages
not designed to contain mercury vapor represent a real health and safety
concern.
