Environmental Fate:

Lead is very persistent in soil and sediments. No data on environmental degradation. Mobility of

metallic lead between ecological compartments is slow. Bioaccumulation of lead occurs in aquatic

and terrestrial animals and plants but little bioaccumulation occurs through the food chain. Most

studies include lead compounds and not elemental lead.

Environmental Toxicity: Aquatic Toxicity:

Sulfuric acid:

24-hr LC

, freshwater fish (Brachydanio rerio): 82 mg/L

96 hr- LOEC, freshwater fish (Cyprinus carpio): 22 mg/L

Lead:

48 hr LC

(modeled for aquatic invertebrates): <1 mg/L, based on lead bullion

Appropriate Method of Disposal of substance:

Lead-acid batteries are completely recyclable. Return whole scrap batteries to distributor,

manufacturer or lead smelter for recycling. 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.

SECTION 11: TOXICOLOGICAL INFORMATION

Routes of Entry:

Electrolyte: Harmful by all routes of entry. Under normal conditions of use, sulfuric acid vapors and

mist are not generated. Sulfuric acid vapors and mist may be generated when product is

overheated, oxidized, or otherwise processed or damaged.

Lead compounds: Under normal conditions of use, lead dust, vapors, and fumes are not generated.

Hazardous exposure can occur only when product is heated above the melting point, oxidized

or otherwise processed or damaged to create dust, vapor, or fume.

Acute Toxicity:

Inhalation LD

Electrolyte: LC

rat: 375 mg/m

; LC

: guinea pig: 510 mg/m

Elemental Lead: Acute Toxicity Point Estimate = 4500 ppmV (based on lead bullion)

Oral LD

Electrolyte: rat: 2140 mg/kg

Elemental lead: Acute Toxicity Estimate (ATE) = 500 mg/kg body weight (based on lead

bullion)
