| The present paper involves their results in the pollutant contributions to the aquatic ecosystems according to the products processed in different productive facilities of the Cuba Island, and concerning to the most significant fishing resources as lobster, white shrimp, tuna, shark, snapper, mackerel, jack and bill fish. The polluting loads in 12 years (between 1955 and 1999) respond to the indicators BOD, QOD, TP, TNK and N-NH4. The captures for those years were approximately between 3 950 and 23 970 tons, with fluctuations of BOD loads between 56 and 342 tons and of DQO between 111 and 676 tons. The principal nutrients contribution was the nitrogen, followed by the phosphorous and finally the ammonium, representing a total contribution of 136,3; 52,7... |
