China is being accused of levying quotas, duties and procedural restrictions on exports of such raw materials as bauxite, coke, fluorspar, magnesium, manganese,
yellow phosphorus and zinc.
For instance, Washington complains: "China imposes export duty rates, 'temporary' export duty rates, and/or 'special' export duty rates of various magnitudes on bauxite, coke, fluorspar, magnesium, manganese, silicon metal,
yellow phosphorus, and zinc" not permitted under China's WTO accession agreement.
The raw materials in question are bauxite, coke, fluorspar, magnesium, manganese, silicon metal, silicon carbide,
yellow phosphorus and zinc.
Yunnan Province is a key location for
yellow phosphorus production, which is the key feedstock for P205.
Over- or underheating or improper mixing can generate toxic by-products such as lead oxide, aluminum hydroxide, mercury vapor, iodine, phosphine, and
yellow phosphorus. These chemicals become a threat to all who come in contact with them when they are released into the air, septic systems, streams, or soil, or when they permeate furniture, carpets, or air vents.
Because nitric oxide (NO), which makes up about 95 percent of most [NO.sub.x] emissions, is not water soluble, it passes through this limestone/water slurry and out into the atmosphere -- unless, that is,
yellow phosphorus is added to the scrubbing mist.
