Agriculture pollution control

Carbon-14. Carbon-14 is a major research tool. It is used pharmaceutical research, biological research, agriculture, pollution control, and archeology. 

Over the past decade, water pollution control has progressed from an art to a science. Increased emphasis has been placed on the removal of secondary pollutants, such as nutrients and refractory organics, and on water reuse for industrial and agricultural purposes. This in turn has generated both fundamental and appHed research, which has improved both the design and operation of wastewater treatment faciUties. 

Air pollution control statistical planners, agricultural biologists, biologists, computer specialists, economists, management analysts, mathematicians, microbiologists, ph)rsicists, phytotoxicologists, researchers, research analysts, research scientists, research specialists, scientists (environmental and unspecified), statisticians, and statistical analysts. 

The suitability of gas absorption as a pollution control method is generally dependent on the following factors 1) availability of suitable solvent 2) required removal efficiency 3) pollutant concentration in the inlet vapor 4) capacity required for handling waste gas and, 5) recovery value of the pollutant(s) or the disposal cost of the unrecoverable solvent. Packed-bed scrubbers are typically used in the chemical, aluminum, coke and ferro-alloy, food and agriculture, and chromium electroplating industries.

McKee s compendium was published by the state board in 1952. Entitled Water Quality Criteria, it was deeply infused with the policy that the chemical industry had advocated since the 30s and California had enacted in the Dickey Act—to promote waste disposal as a beneficial use of public waters. The deterioration of water quality, McKee later wrote, was a trend that cannot be stopped or reversed... unless the industrial and agricultural development of this Nation is to be curtailed. 25 Water Quality Criteria, and through it the philosophy of the Dickey Act, came to influence water pollution control practice far beyond California s borders. Yet this publication owed its official imprimatur and the influence that flowed from it not to its scientific merits but to a political decision of the California legislature.
