The visual effects of repeated exposure to carbon dioxide (C02) at levels commonly regarded as innocuous were investigated. Exposure to C02 varied cyclically from .03 (air) to 3.0%, at one atmosphere pressure, every 24 hours for a period of six days. A battery of visual tests was administered during this period and in control periods both before and after the exposure to carbon dioxide. Among t...

Experimental approaches attempt to determine the routes by which crustal carbonatite magmas can be derived from C02-bearing peridotite at high pressures. The intimate association of kimberlite and carbonatite on a small scale il· lustrates links in the processes. Carbonation of peridotite by C02 can cause the generation of near-solidus carbonatitic liquid from mantle peridotite at depths greate...

Three months old plants of the Chinese tung-oil tree Aleurites montana were cultivated for 4 months in air containing an increased amount of 700 ppm C 0 2. During the exposure to 700 ppm C 0 2 the plants exhibited a considerably stronger growth (30-40% ) in compari­ son to the control plants (grown in normal air). In these C02-plants during the entire analyz­ ing period the amount of soluble pr...
