Record 1 2020-08-10

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
  • Pollutants
  • Climate Change
DEF

A climate feedback involving changes in the properties of [the] land and ocean carbon cycle in response to climate change.

OBS

In the ocean, changes in oceanic temperature and circulation could affect the atmosphere-ocean CO2 flux; on the continents, climate change could affect plant photosynthesis and soil microbial respiration and hence the flux of CO2 between the atmosphere and the land biosphere.

French

Domaine(s)
  • Phénomènes météorologiques, climatiques et atmosphériques
  • Agents de pollution
  • Changements climatiques
CONT

La deuxième série de processus est liée à la rétroaction climat-cycle du carbone. Il s'agit de la rétroaction du changement climatique anthropique sur les différents phénomènes d'absorption du carbone. Le changement climatique se traduit par des modifications de la température de l'eau, des courants marins, de la production biologique océanique. Si ces modifications augmentent le puits de carbone, elles freineront le changement climatique et induiront une rétroaction négative. Au contraire, dans l'hypothèse d'une diminution du puits, ces changements vont conduire à une rétroaction positive qui accélérera le phénomène.

Record 2 2011-09-08

English

Subject field(s)
  • Anti-pollution Measures
  • Soil Pollution
CONT

Biopiles, also known as biocells, bioheaps [and] biomounds... are used to reduce concentrations of petroleum constituents in excavated soils through the use of biodegradation. This technology involves heaping contaminated soils into piles(or "cells") and stimulating aerobic microbial activity within the soils through the aeration and/or addition of minerals, nutrients, and moisture. The enhanced microbial activity results in degradation of adsorbed petroleum-product constituents through microbial respiration.

Key term(s)
  • bio-pile
  • bio-mound
  • bio-cell
  • bio-heap

French

Domaine(s)
  • Mesures antipollution
  • Pollution du sol
DEF

Andain de terre ou de déchet réalisé après excavation et criblage.

CONT

Un biotertre peut être équipé par des drains d'aération ou encore être arrosé par une solution nutritive afin d'optimiser les conditions de croissance et de fonctionnement des microorganismes.

Key term(s)
  • bio-tertre
  • bio-pile
