Lead
Repeated exposure to lead and lead compounds in the workplace may result in nervous system toxicity. Some
toxicologists report that abnormal conduction velocities in person with blood lead levels of 50 μg/100 ml or
higher. Heavy lead exposure may result in central nervous system damage, encephalopathy and damage to
the blood-forming (hematopoietic) tissues.
Additional information
Very little chronic toxicity data available for elemental lead. Lead is listed by IARC as a 2B carcinogen: possible
carcinogen in humans. Arsenic is listed by IARC, ACGIH, and NTP as a carcinogen, based on studies with high
doses over long periods of time. The other ingredients in this product, present at equal to or greater than 0.1% of
the product, are not listed by OSHA, NTP, or IARC as suspect carcinogens. The 19
th
Amendment to EC Directive
67/548/EEC classified lead compounds, but not lead in metal form, as possibly toxic to reproduction. Risk phrase
61: May cause harm to the unborn child, applies to lead compounds, especially soluble forms.
SECTION 12: ECOLOGICAL INFORMATION
Persistence & degradability
Lead is very persistent in soils / sediments. No data available on biodegradation.
Bio-accumulative potential (inc. mobility)
Mobility of metallic lead between ecological compartments is low. Bioaccumulation of lead occurs in aquatic
and terrestrial animals and plants, but very little bioaccumulation occurs through the food chain. Most studies
have included lead compounds, not solid inorganic lead.
Aquatic toxicity (test results & comments)
Sulfuric acid: 24-hour LC50, fresh water fish (Brachydanio rerio): 82 mg/l
96-hour LOEC*, fresh water fish (Cyprinus carpio): 22 mg/l
Lead (metal): No data available
