reverberation time was reduced by 20% to 50%. After the treatment the perceived noise
disturbance level decreased slightly but not significantly and the proportion of the staff
that often or very often planned the daily activities to reduce the noise level had
decreased from about 39% to 25%. Similarly, the percentage that often or very often had
a need for silence after work had decreased from 42% to 37%.

Exposure to lead has been shown to be harmful to adults; it is a teratogen, it can
damage the peripheral nervous system, and it adversely affects the reproductive system.
Professional lead-based paint remediation workers are at risk of exposure to lead dust.
The authors’ study was conducted to determine if these remediation workers transfer lead
from their work site to their vehicles and then potentially expose their families. It was
hypothesized that remediation workers transported the lead from the remediation work
site to the floorboards of their vehicles due to not following required protective
equipment use. The laboratory’s level of quantitation for lead on the wipe samples, 10
µg/ft², was used to indicate lead contamination. This level was exceeded in 50% of the
floorboards sampled. These results confirm that many vehicle floorboards used by
remediation workers are contaminated with lead dust, potentially resulting in transfer of
lead dust. The ultimate detrimental outcome could be the transfer of lead particles to
other family members, causing the poisoning of a child or other at-risk person.
Direct From ATSDR: The Toxicological Profile Program at ATSDR
Henry G. Abadin, MSPH
The Superfund Amendments and Reauthorization Act of 1986 (SARA) directs
ATSDR to develop a prioritized list of hazardous substances of greatest public health
concern at facilities on the National Priorities list and to develop comprehensive
Toxicological Profiles for those substances. This month’s column describes the process
ATSDR follows to create and update toxicological profiles.
