<tr><th>Potential Health Effects </th></tr>
<tr><td>*'''Inhalation''': 
Lead can be absorbed through the respiratory system. Local irritation of bronchia and lungs can occur and, in cases of acute exposure, symptoms such as metallic taste, chest and abdominal pain, and increased lead blood levels may follow. See also Ingestion. </td></tr>
<tr><td>*'''Ingestion''': 
POISON! The symptoms of lead poisoning include abdominal pain and spasms, nausea, vomiting, headache. Acute poisoning can lead to muscle weakness, "lead line" on the gums, metallic taste, definite loss of appetite, insomnia, dizziness, high lead levels in blood and urine with shock, coma and death in extreme cases. </td></tr>
<tr><td>*'''Skin Contact''': 
Lead and lead compounds may be absorbed through the skin on prolonged exposure; the symptoms of lead poisoning described for ingestion exposure may occur. Contact over short periods may cause local irritation, redness and pain. </td></tr>
<tr><td>*'''Eye Contact''': 
Absorption can occur through eye tissues but the more common hazards are local irritation or abrasion. </td></tr>
<tr><td>*'''Chronic Exposure''': 
Lead is a cumulative poison and exposure even to small amounts can raise the body's content to toxic levels. The symptoms of chronic exposure are like those of ingestion poisoning; restlessness, irritability, visual disturbances, hypertension and gray facial color may also be noted. </td></tr>
<tr><td>*'''Aggravation of Pre-existing Conditions''': 
Persons with pre-existing kidney, nerve or circulatory disorders or with skin or eye problems may be more susceptible to the effects of this substance.</td></tr>
<tr><td>*'''Airborne Exposure Limits''':
For lead, metal and inorganic dusts and fumes, as Pb:<br />
-OSHA Permissible Exposure Limit (PEL): 0.05 mg/m3 (TWA)<br />
For lead, elemental and inorganic compounds, as Pb:<br />
-ACGIH Threshold Limit Value (TLV): 0.05 mg/m3 (TWA), A3 animal carcinogen<br />
For lead, inorganic:<br />
-NIOSH Recommended Exposure Limit (REL): 0.1 mg/m3 (TWA) </td></tr>
