Combustion iron distribution and deposition

Atmospheric iron deposition: global distribution, variability, and human perturbations.

Atmospheric inputs of iron to the open ocean are hypothesized to modulate ocean biogeochemistry. This review presents an integration of available observations of atmospheric iron and iron deposition, and also covers bioavailable iron distributions. Methods for estimating temporal variability in ocean deposition over the recent past are reviewed. Desert dust iron is estimated to represent 95% of...

Simulated global distribution and deposition of reactive nitrogen emitted by fossil fuel combustion

We use the medium resolution (265 km horizontal grid) GFDL general circulation transport model to simulate the global spread and deposition of reactive nitrogen emitted by fossil fuel combustion. The nitrogen species are transported as a single tracer with no explicit chemistry. Chemical reactions are only present implicitly in the bulk coefficients for dry and wet removal. The observed wet dep...

Iron deposition in tissues.

Among clinical conditions w ith increased tissue iron, id iopathic hem o­ chrom atosis is un ique. I t is associated w ith increased absorption and iron deposition in all tissues. E xperim ental m odels to study iron absorption and deposition in tissues m ay p rovide inform ation on the processes associated w ith excess iron uptake. Low pro tein high fat d iets induced excess iron deposition in...

Brain Iron Deposition

The brain uses iron for many essential processes (1-4). The extent of iron utilization is heavily dependent on local functional requirements, leading to significant variations in tissue iron concentrations throughout the brain (5-7). This was graphically illustrated nearly a century ago in the first colour illustrations of the differential distribution of iron throughout the brain architecture,...
