Newfoundland, rarely exceeded 3.0 pg/L (Addison et al. 1972a), the concentration in Yellow Lake ranged from 0.005 to 0.01 pg/L, and the level in the Arkansas River, which is connected to the lake, ranged from 0.003 to 0.004 pg/L (EPA 1989). Similarly, phossy water discharged into adjacent water from the white phosphorus manufacturing plant in Long Harbour contained elemental phosphorus, as indicated by levels of elemental phosphorus in the sediment (see Section 5.4.3). 

Before the waste-water treatment facility was instituted, the concentrations of elemental phosphorus in the sediment in the vicinity of the effluent discharge pipe of the phosphorus manufacturing plant in Long Harbour, Placentia Bay, Newfoundland, ranged from 5.5 to... 

Albright and Wilson. This company started by making phosphorus for matches in 1844. In the late 1960s a decision was taken to relocate phosphorus manufacture in a new plant in Newfoundland. However this was plagued with technical and pollution problems, which had such a serious effect on the company s finances that major help from the U.S. company Tenneco was... 

In Idaho, U.S.A., at the Henry Mine (Monsanto Corporation), the producing beds of the Meade Peak Member of the Phosphoria Formation are very soft and dip at an es of 50°-60 . Bulldozers with vertical scraper blades peel off layers of ore then earthmovers scrape up the ore and move it to storage piles according to grade. The high wall is benched approximately every 50 ft vwth 10- to 15-ft benches. The ore is transported by truck to the plant on a spedal road where it is used for elemental phosphorus manufacture. 

Ilie quantfl.y of phosphorus manufactured in the year 1874 amounted to 250 tons, the greater portion of which is used for the manufacture of ludfer matches, a certain anwont being employed as avermin pd8on,and a small quantity bdng used in oheraioal laboratories,...
