Record 2 2011-08-26

English

Subject field(s)
  • Chemical Elements and Compounds
Universal entry(ies)
DEF

An oxide of lead made by controlled heating of metallic lead having the formula PbO or OPb, appearing under the form of yellow crystals, insoluble in water, soluble in acids and alkalies, used chiefly in making plates for lead-lead acid cells, in compounding rubber, in glass, glazes, paints, varnishes and vitreous enamels, and in the manufacture of other lead compounds.

OBS

Commercial grades are yellow to reddish, depending on treatment and purity.

OBS

Not to be confused with "massicot" (q.v.), which refers to the natural lead monoxide (lead ocher).

OBS

litharge: This term is sometimes used broadly as a synonym for lead monoxide, but it refers specifically to lead monoxide obtained in flake or powdered form by processes carried out at temperatures above the melting point of the oxide.

OBS

lead monoxide: obsolete form.

Subject field(s)
  • Chemical Elements and Compounds
  • Pollutants
  • Mining Dangers and Mine Safety
Universal entry(ies)
DEF

A colourless and odourless gas ..., which is formed in the incomplete combustion of carbon or carbon compounds, [and which] is very poisonous, forming a very stable complex with haemoglobin ...

CONT

Carbon monoxide is formed through incomplete oxidation of carbon. It has a 5-month residence time in the atmosphere, where its concentration is increasing from 0.8% to 1.5% per year. About three-quarters of the present global emission of 1 billion metric tons of carbon as carbon monoxide results from human activity. Forest clearing in the tropics accounts for about 15% (160 million metric tons), and the burning of savanna for agricultural purposes adds another 10% ... The principal natural sources of carbon monoxide include the oceans, plant emissions, and photochemical oxidation of natural non-methane hydrocarbons in the atmosphere (240 million metric tons).

OBS

Carbon monoxide and the nitrogen oxides, while not themselves greenhouse gases, increase the amount of methane and ozone in the troposphere.

OBS

carbon oxide: A generic compared to "carbon monoxide", but may be used if the context is clear enough.

OBS

white damp: term restricted to mining.

OBS

carbon monoxide: form recommended by the IUPAC (International Union of Pure and Applied Chemistry) for the systematic name corresponding to the CAS number indicated on the present record; term adopted by Environment Canada : used in the list of pollutants measured in the National Air Pollution Surveillance Network (NAPS).

  • Éléments et composés chimiques
  • Agents de pollution

Entrée(s) universelle(s)
DEF

Gaz incolore, inodore, toxique, combustible, réducteur, de formule CO.

OBS

Le monoxyde de carbone est un gaz dit «sans effet de serre» puisqu'il n'a pas d'effet radiatif direct; son rôle cependant, puisqu'il a des effets radiatifs indirects importants, est considérable dans le réchauffement climatique.

OBS

oxyde de carbone : Ce terme est un générique par rapport à «monoxyde de carbone», mais on peut l'utiliser si le contexte ne présente pas de risque de confusion.

OBS

monoxyde de carbone : forme recommandée par l'UICPA (Union internationale de chimie pure et appliquée) pour le nom systématique correspondant au numéro CAS indiqué sur la présente fiche; terme retenu par Environnement Canada : utilisé dans la liste des polluants mesurés par le Réseau national de surveillance de la pollution atmosphérique (RNSPA).
