| Abstract |
The concentrations of phosphate-P, ammonia + amino acid-N, nitrite-N, and nitrate-N were measured at 4 sites in the polluted Masan Bay from 1978 to 1982. The mean concentration of phosphate-P, ammonia + amino acid-N, nitrite-N and nitrate-N in each site varied 0.68-1.90 ㎍ at-P/ℓ, 1.21-4.36 ㎍ at-N/ℓ, 0.36-3.23 ㎍ at-N/ℓ and 2.17-29.45 ㎍ at-N/ℓ, respectively. At site 1 and 2, nearby Masan City, the concentration of nitrogen was gradually increasing according to the increase of the population of the city and the N/P ratios at site 1 and 2 reached more than 40. |
