SULFUR SPECIES [6 records]

Record 1 2007-10-22

English

Subject field(s)
  • Chemical Elements and Compounds
CONT

... for a global aircraft field-sampling program,... further development of in situ tropospheric sensors [are] a high priority. [Tropospheric] species for which [appropriate] instrumentation... does not exist... include NOx, C2 to C10 hydrocarbons, peroxides(e. g., H02, H202, and CH3O2), hydrogenated sulfur compounds(e. g., H2S, CH3SH, CH3SCH3, CH3SSCH3, and CH3SCH3), and NH3.

French

Domaine(s)
  • Éléments et composés chimiques
CONT

Le soufre est une composante naturelle du pétrole brut et doit être extrait par un procédé de raffinage. Le traitement de l'essence et du diesel pour ramener leur teneur en soufre à 10 ppm au maximum repose sur la méthode de l'hydrodésulfuration. Celle-ci consiste à comprimer et à chauffer fortement des produits contenant du soufre dans un réacteur en présence d'hydrogène et d'un catalyseur chimique jusqu'à ce que les composés soufrés soient dégagés par l'hydrogène sous l'action du catalyseur. Le soufre ainsi extrait quitte le réacteur sous la forme de soufre hydrogéné.

  • Chemical Elements and Compounds
  • Treatment of Wood
OBS

A wood preservative produced by Kodiak Inc.

CONT

Copper dimethyldithiocarbamate(CDDC) is a reaction product formed within the wood after treatment with two different treating solutions. It contains copper and sulfur compounds. CDDC protects against decay fungi and insects.... [It] is standardized for treatment of Southern Pine and some other pine species.

Record 3 1993-01-23

English

Subject field(s)
  • Insects, Centipedes, Spiders, and Scorpions
DEF

Any of various yellow or orange butterflies of the family Pieridae.

CONT

Sulfurs are yellow or orange, and [the] most common species have the wings bordered with black; some sulfurs are very common butterflies; larvae of the common species feed on clover.

CONT

Whites, sulfurs and orange-tips make up the Pieridae family of butterflies.

OBS

Used in the plural, the term "sulfurs" often represents the vernacular generic term that regroups the following genera-Colias, Pieris, Pyristia-that make up the family of Pieridae butterflies. Semantically, the term "sulfur" evokes a sulfur-yellow butterfly, roughly corresponding to the French term "coliade" or its Latin equivalent "Colias", the latter which is usually post-qualified by another Latin term specifying the exact species, e. g. Colias philodice, Colias interior, Colias eurytheme, Colias hyale. In some of the French translated texts consulted, the more colorful term "soufré" has been used, whereas in some other non-translated texts, "coliade" has been used. Before choosing the appropriate equivalent, the translator into French should determine if the term "sulfur", found in the singular, denotes in the source text a specific species in the family or whether it used to represent all the above-mentioned genera of the Pieridae family. In French, one could use "soufré" as a generic term when referring to all the species "Colias" as a whole and whenever the English uses "sulfurs" or "sulfur butterflies", in the plural. The term "coliade" would then be reserved for cases where one would need to specify or describe a particular species. e. g. coliade de la luzerne, coliade intérieur, coliade du trèfle, petit coliade, etc.

French

Domaine(s)
  • Insectes, mille-pattes, araignées et scorpions
DEF

Joli papillon de jour, répandu dans les régions tempérées, de coloration ordinairement jaune soufre varié d'orange [...] Famille des Piéridés.

CONT

soufré : Les ailes de ce papillon sont d'un jaune de soufre chez le mâle et blanc jaunâtre chez la femelle. Tous deux ont une tache noire au centre des ailes antérieures et une autre, orange, sur les postérieures. En outre, le mâle a les antérieures largement bordées de noir.

OBS

Attention : en plus des «Sulfurs», le terme «coliade» peut aussi traduire ce que les Anglais appellent les «orange-tips» ou «orange-tip butterflies» (l'Orangé).

Record 4 1986-08-06

English

Subject field(s)
  • Lichens
CONT

Sulfur dioxide damage to epiphytic lichens is well-known and has long been studied. It seems that the sensitivity of some of the lichen species is great enough to cause damage at concentrations tolerable to most other plants, including conifer trees. The economic value of the lichens is as a rule not great, and their main direct importance is that they may be used as indicators.

French

Domaine(s)
  • Lichens
CONT

Les travaux de HAWKSWORTH et ROSE (1970) ont permis l'établissement d'une échelle de sensibilité des espèces lichéniques vis-à-vis de la pollution atmosphérique. En France, c'est seulement depuis une dizaine d'années que la détection et l'estimation de la pollution atmosphérique acide à partir des lichens ont été réalisées dans diverses régions.

Record 6 1985-08-27

English

Subject field(s)
  • Air Pollution
CONT

Sulphur species in solution eventually reach equilibrium with the ambient SO2 concentration (further uptake is much diminished and is dependent on the removal of S(IV) from solution usually by oxidation to S(VI) (sulphate), a reaction that generates acidity).
