  • Metrology and Units of Measure

  • Environmental Studies and Analyses
  • Toxicology
CONT

Parts per million-ppm-is commonly used as a dimensionless measure of small levels(concentrations) of pollutants in air, water, body fluids, etc. Parts per million is the molar mass, volume or mass ratio between the pollutant component and the solution.... In the metric system ppm for mass can be expressed in terms of milligram versus kg where 1 mg/kg=1 part per million.

OBS

part per 106: written part per 106.

Key term(s)
  • parts per million

French

Domaine(s)
  • Unités de mesure et métrologie
  • Chimie analytique
  • Études et analyses environnementales
  • Toxicologie
CONT

Partie par million (ppm). C'est un quotient sans dimension représentant un rapport de 10-6 (1 pour 1 million). Ce rapport peut s'appliquer par exemple à des masses ou à des volumes. Ainsi, quand on parle d'un contenu de 400 ppm (ou plus précisément ppmv [partie par million en volume]) de CO2 dans l'atmosphère, cela signifie qu'un litre d'air contient en moyenne 0,4 ml de dioxyde de carbone.

OBS

partie par 106 : s'écrit partie par 106.

Key term(s)

CONT

Grasas y Aceites. Se refiere a los compuestos derivados del petróleo que sólo son solubles en hexano y completamente insolubles en el agua. La norma de la OMS marca 1 ppm (1 parte por millón, esto es un miligramo por litro) de grasas y aceites, sin embargo, en México la norma es de 65 ppm.

CONT

En general, la concentración de monóxido de carbono acompaña los cambios de densidad del tránsito que se suceden a lo lorgo del día. El descanso nocturno es suficiente para borrar la memoria de la contaminación registrada el día anterior. Cada día comienza entonces con bajos niveles de concentración, para llegar a niveles cercanos a la alarma (9ppm - partes por millón - como promedio de 8 horas).

OBS

ppm [in English]: Abreviatura de «parts per million» (partes por millón). Se use para expresar tolerancias; por ejemplo, la variación de frecuencia de un oscilador patrón.

English

Subject field(s)
  • Biochemistry
CONT

Uptake and biotransformation of radioactive choline(3H-Ch) have been studied in P2 fractions from different brain regions of mice treated with different doses of sodium pentobarbital(45-120 mg/kg intraperitoneally) or saline. Sodium dependent uptake(SDU) has been measured as the difference between results of incubations with Na+ in the incubation medium and when the sodium salts were replaced by Trisphosphate and sucrose.

OBS

(Taken from INDEX MEDICUS).

OBS

The term "dependent," when used as an adjective as is the case here, is more frequently written with an "e." "Dependant" with an "a" represents the noun form.

Subject field(s)
  • Food Additives
  • Collaboration with the FAO
CONT

Acceptable daily intakes(ADIs) are expressed in terms of mg [milligram] per kg [kilogram] of body weight per day. In certain cases, however, food additives are more appropriately limited by their levels of treatment. This situation occurs most frequently with flour treatment agents. It should be noted that the acceptable level of treatment is expressed as mg/kg of the commodity. This should not be confused with an ADI.

French

Domaine(s)
  • Additifs alimentaires
  • Collaboration avec la FAO
CONT

Les doses journalières admissibles (DJA) sont exprimées en termes de mg [milligramme] par kg [kilogramme] de poids corporel par jour. Dans certains cas, toutefois, les additifs alimentaires sont circonscrits de façon plus appropriée par leurs limites de traitement. Cette situation apparaît le plus fréquemment avec les agents de traitement de la farine. On devrait noter que la limite acceptable de traitement est exprimée en tant que mg/kg du produit. Ceci ne devrait pas être confondu avec une DJA.

Doxazosin crosses the placental barrier. Studies in rabbits and rats at daily oral doses of up to 40 and 20 mg/kg respectively have revealed no evidence of teratogenic effect. The rabbit study however, was compromised by the failure to use a maximally tolerated dose of doxazosin.

Intravenous immune globulin are recommended unequivocally for some diseases... Large amounts of immune globulin, such as 400 to 2000 mg/kg are proposed over a period of two to five days. The safety of this treatment, which may be introduced without any special structure, is a very interesting quality of the intravenous immune globulin therapy. However, comparative efficacy against reference therapy, surveillance for long-term positive and adverse effects and cost-effectiveness should be carried out.
