- As an example, an ICE-powered Volvo XC40 SUV can produce as much as 58 tonnes over its 200,000km life cycle. (autoexpress.co.uk)
- In vivo toxicity assessment of occupational components of the carbon nanotube life cycle to provide context to potential health effects. (cdc.gov)
- Our study provides perspective that, while the number of workers and consumers increases along the life cycle, toxicity and/or potential for exposure to the as-produced material may greatly diminish. (cdc.gov)
Sink4
- Otherwise, this carbon is attributed to the land sink and is missing from the ocean sink. (phys.org)
- By tracking this heat, the researchers discovered that the ocean in the southern hemisphere is a much smaller carbon sink than previously thought and that the land at the same latitude is an almost non-existent source of carbon. (phys.org)
- As a result, the extent to which land acts as a sink or source is largely deduced by assigning it whatever carbon is left over after ocean data are considered, Resplandy said. (phys.org)
- In the Connected article Trees, seas and soil discover what a carbon sink is and why they are so important. (sciencelearn.org.nz)
Fixation4
- Some bacteria specifically involved in carbon fixation are Cyanobacteria (such as Chroococcus , Nostoc , and Spirulina ) and some species of Aquifex ,such as Aquifex aeolicus . (kenyon.edu)
- This pathway converts a C3 metabolite to two acetyl-CoA by fixation of one additional CO2 equivalent, or assimilates glyoxylate, a photorespiration intermediate, to produce acetyl-CoA without net carbon loss. (osti.gov)
- This work provides a strategy to improve carbon fixation efficiency in photosynthetic organisms. (osti.gov)

Humans1
- Humans, through the migration of populations, agricultural practices and fossil fuel consumption have interfered with the natural carbon cycle of the planet, yielding significant consequences. (horiba.com)

Molecules2
- The major function of microbes in the Carbon Cycle is as decomposers-- degraders of complex organic molecules that would otherwise permanently sequester carbon, keeping it from being used by organisms. (kenyon.edu)
- Carbon dioxide molecules provide the initial greenhouse heating needed to maintain water vapor concentrations. (nasa.gov)
