Lead (II) carbonate is a common constituent; the sulfate or chloride may also be present in urban or maritime settings. This layer makes bulk lead effectively chemically inert in the air. Finely powdered lead, as with many metals, is pyrophoric, and burns with a bluish-white ciation: /ˈlɛd/ (LED). VIII ECHA SCIENTIFIC REPORT ON LEAD AND ITS COMPOUNDS Table Methods for lead and lead compounds in air Table Measured blood lead concentrations in the general population with specific lead.

Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula Pb occurs in two polymorphs: litharge having a tetragonal crystal structure, and massicot having an orthorhombic crystal applications for PbO are mostly in lead-based industrial glass and industrial ceramics, including computer al formula: PbO.
This material contains Lead nitrate (listed as Lead, inorganic compounds), >99%, (CAS# ) which is subject to the reporting requirements of Section of SARA Title III and 40 CFR Part Clean Air Act: CAS# (listed as Lead compounds) is listed as a hazardous ai r pollutant (HAP). General Information. Elemental lead is a soft, highly malleable, and ductile metal that is insoluble in water.  Lead rarely exists naturally in its pure form.  It is typically found in low concentrations in the earth’s crust as the mineral galena (lead sulfide).  Lead forms both inorganic and organic compounds with many substances, including acetate, arsenic, antimony, chlorine, oxygen.

This Monograph re-evaluates the potential carcinogenic hazards to humans from exposure to inorganic and organic lead compounds. Human exposure comes from lead-contaminated air, dust, soil, water and food and through inhalation and ingestion.
Recent human exposure has arisen predominantly from the widespread use of leaded gasoline. This monograph re-evaluates the potential carcinogenic hazards to humans from exposure to inorganic and organic lead compounds.
Human exposure comes from lead-contaminated air, dust, soil, water and food and through inhalation and ingestion. Recent human exposure has arisen predominantly from the widespread use of leaded gasoline. This is followed by an overview of lead inorganic compounds, including halides, pseudohalides, oxides and chalcogenides, hydroxides and their chalcogenide analogs, alkoxides, oxoacids, O‐donors, S‐ and Se‐donors, Group 15 donors, compounds with lead‐transition metal bonds, and finally metallic clusters (Zintl phases).Cited by: 1.

An update is currently underway and will be available as. INORGANIC AND ORGANIC LEAD COMPOUNDS Metallic lead and several inorganic and organic lead compounds have been considered by previous working groups convened by IARC (IARC, ).
New data have since become available, and these are included in the present monograph and have been taken into consideration in the g: air book. A TLV 8-hour TWA of μg/m 3 for lead and inorganic compounds in air was first adopted in and has undergone several revisions.
The most recent revision in recommended a TLV-TWA of 50 μg/m 3. ACGIH classifies lead as a confirmed animal carcinogen with unknown relevance to humans. Laboratory method using flame or electrothermal atomic absorption spectrometry. Note 1: This method updates and replaces MDHS 6/ The principal change is that the revised method now recommends use of the sampling procedure for inhalable dust described in MDHS 14/ However, existing users may continue to use the single-hole sampler recommended for sampling lead in air Missing: air book.

The Threshold Limit Value (TLV) for lead compounds, such as lead acetate, lead arsenate, lead carbonate and lead phosphate, is mg/m 3. The TLV is for lead chromate and tetraethyl lead.
For total dust, lead metal and most of its inorganic compounds, the TLV is mg/m 3 in some g: air book. APPLICABILITY: The working range is to >1 mg/m 3 for a L air sample.
The method is applicable to elemental lead, including Pb fume, and all other aerosols containing lead. This is an elemental analysis, not compound specific. Aliquots of the samples can be analyzed separately for additional elements.
