Open field experiments were also conducted at the New Jersey Experiment Station by Lipman et al. (1928) during the period 1908 to 1927. The percent nitrogen recoveries for the 20-year period from limed soils were calcium nitrate 42, ammonium sulfate 42, calcium cyanamide 36, sodium nitrate 33, fish scrap 26, tankage 26, and manure 12. On the unlimed soils the recoveries in the same order were 32, 21, 33, 37, 37, 21, and 17%. 

To illustrate the use of an emission factor, let us turn to the fish-canning industry. From AP-42, section 9.13.1-7 and Table 3, entitled Uncontrolled Emission Factors for Fish Canning and Byproduct Manufacture, emission factors are shown for particulate emissions, trimethylamine (fish odor), and hydrogen sulfide (rotten egg odor). Emissions from the fish scrap cookers for both fresh fish and stale fish are shown. Notice that the particulate emissions are negligible for the cookers. Trimethylamine (fish odor) has an emission factor of 0.3 Ib-tiimethylamine/ton of fresh fish cooked. If we are cooking 5 tons of fresh flsh/hr, then the uncontrolled fish odor emission to the atmosphere is 0.3 Ib-trimethylamine/ton of fresh fish cooked X 5 tons of fresh fish/hr = 1.5 Ib-trimethylamine/ hr. Since the chemical responsible for typical fish odor is trimethylamine, 1.5 Ib/hr will certainly be noticed by residents noses downwind of the plant. 

Fish meal syn. fish scrap is a protein-rich, dried fertilizer or animal feed processed from the inedible portion of fish by dry or wet rendering. It may be spontaneously combustible due to oxidation catalyzed by moisture, autooxidation of remaining fish oils, bacterial buildup, or a combination of all...
