Week 3 Discussion

Hazards of Exposure to
Lead

Discuss the hazards of
nonoccupational exposure to lead dust and fumes in the United States. People
discovered the ease with which lead metal could be molded into useful objects
thousands of years ago. Before long, ancient medical writers began describing
myriad occupational health problems suffered by heavily exposed lead miners and
smelters. In time, health problems from nonoccupational exposure to lead at
lower doses were also discovered.

In your response,
address the following:

Discuss the adverse
health effects of lead that occur at high levels of exposure in the context of
a poisoning case. Review briefly a famous nonoccupational lead poisoning
(plumbism) case from the past and list the health problems due to lead that
this individual suffered.

Contrast the symptoms
from high lead exposure to the adverse health effects of lead that occur at
lower levels of exposure.

Describe one way in
which nonoccupational exposure to lead occurs in the United States today
through drinking, eating or other ingestion, or through breathing. Give an
example of a typical exposure scenario for the route of exposure you choose.

Review the key public
health preventive strategies used in the United States to prevent illness from
lead exposure for the route of exposure you choose. Include primary prevention
(stopping the exposure from occurring) and secondary prevention (detecting
lead-exposed persons, treating them when medically warranted, and preventing
additional exposure in the future).

Support your answers
with appropriate research and reasoning and initiate comments on the postings
of at least two of your peers.
