Material Safety Data Sheet
11. Toxicological Information
GENERAL:
The primary routes of exposure to lead are ingestion or inhalation of dust and fumes.
ACUTE:
INHALATION/INGESTION: Exposure to lead and its compounds may cause headache, nausea, vomiting, abdominal spasms,
fatigue, sleep disturbances, weight loss, anemia, and pain in the legs, arms and joints. Kidney damage, as well as anemia, can
occur from acute exposure.
CHRONIC:
INHALATION/INGESTION: Prolonged exposure to lead and its compounds may produce many of the symptoms of short-term
exposure and may also cause central nervous system damage, gastrointestinal disturbances, anemia, and wrist drop.
Symptoms of central nervous system damage include fatigue, headaches, tremors, hypertension, hallucination, convulsions
and delirium. Kidney dysfunction and possible injury has also been associated with chronic lead poisoning. Chronic over-
exposure to lead has been implicated as a causative agent for the impairment of male and female reproductive capacity, but
there is at present, no substantiation of the implication. Pregnant women should be protected from excessive exposure. Lead
can cross the placental barrier and unborn children may suffer neurological damage or developmental problems due to
excessive lead exposure in pregnant women.
12. Ecological Information
In most surface water and groundwater, lead forms compounds with anions such as hydroxides, carbonates, sulfates, and
phosphates, and precipitates out of the water column. Lead may occur as sorbed ions or surface coatings on sediment mineral
particles or may be carried in colloidal particles in surface water. Most lead is strongly retained in soil, resulting in little mobility.
Lead may be immobilized by ion exchange with hydrous oxides or clays or by chelation with humic or fulvic acids in the soil.
Lead (dissolved phase) is bioaccumulated by plants and animals, both aquatic and terrestrial.
13. Disposal Considerations
Lead-acid batteries are completely recyclable. Return whole scrap batteries to distributor, manufacturer or lead smelter for
recycling. For information on returning batteries to us, contact us. For neutralized spills, place residue in acid-resistant
containers with sorbent material, sand or earth and dispose of in accordance with local, state and federal regulations for acid
and lead compounds. Contact local and/or state environmental officials regarding disposal information.
