What Physicians Need to Know About Occupational Lead Exposure
Organization(s): NJ Dept of Health & Senior Services
Under the New Jersey Administrative Code (N.J.A.C. 8:57-3.2), physicians are required to report adult lead toxicity (blood lead _> 25 ug/dl or urine lead _> 80 ug/1) to the New Jersey Department of Health and Senior Services.
The report must include the following information about the case:
- Name and Address of Employer at Time of Exposure
- Date of Onset of Illness
- Year of Birth
- Telephone Number
- Home Address
As a Health Care Provider you have, under the OSHA Lead Standards (29 CFR 1910.025 and 29 CFR 1926.62) primary responsibility for evaluating lead toxicity in the workers who are your patients.
In compliance with state regulations, the New Jersey Department of Health & Senior Services collects and records occupational blood and urine lead reports. The Department also offers assistance to health care providers through consultations, surveillance reports and educational materials

be medically removed–

for blood lead levels greater than or equal to 50 ug/dl; or
for medical conditions that place the employee at increased risk of impairment of health due to lead exposure.
How Often Should Employees
Have Medical Evaluations?
Physical examinations and laboratory testing should be conducted with the following frequencies:

- BLOOD PRESSURE;
- PHYSICAL EXAMINATION with special attention to neurological, gastrointestinal, cardiovascular and renal systems;
- PULMONARY STATUS if respirators are used on the worksite;
Blood lead level; Hemoglobin, hematocrit, red cell indices and examination of peripheral smear morphology; Zinc protoporphyrin level (ZPP); BUN and serum creatinine; Routine urinalysis.
How Often Should Biological Monitoring be Performed?
BLOOD LEAD LEVELS
|Less than 40 ug/dl (last result)||Every 6 months|
|Last result between 40 ug/dl and level requiring medical removal||Every 2 months until two consecutive blood samples indicate a blood lead level below 40 ug/dl|
|Greater than 60 ug/dl or when the average of the last three blood samples taken during the previous 6 month period is 50 ug/dl or greater for general industry; or greater than 50 ug/dl for construction industry.||At least monthly during the removal period of each employee removed from exposure to lead due to an elevated blood lead level.|
