FIRST STUDY ON AMMONIA (NH3) CONTAINED IN THE PARAGOMINAS STREAM IN THE MUNICIPALITY OF THE SAME NAME, SOUTHEASTERN PARÁ
Resumen
Non-ionized or free ammonia is the most toxic nitrogenous substance in the aquatic environment, and the absence of information about it causes a deficiency in the assessment of water quality. This was the gap that guided this research since the generation and disposal of these data can help in the integrated or non-integrated management of the water quality of the Igarapé Paragominas. The objective is to identify the presence or absence in the urban section, characterize the anthropic origin and verify whether or not three parameters associated with water quality act on non-ionized or free ammonia. The method used was hypothetical-deductive with quantitative and qualitative coverage of an observational nature. The data obtained and analyzed indicated that in the five areas analyzed, the occurrence of non-ionized or free ammonia indicated. They also indicated that in areas where the population agglomeration is smaller, the concentration of this gas, in mg/L, is also lower (A1, 0.13 ± 0.04) and, proportionally, to the smaller amount of effluents that enter the sampling area; as this cluster grows, so does the concentration (A2, 0.26 ± 0.04; A3, 0.37 ± 0.17; A4, 0.81 ± 0.44), depending on the inverse occurrence; the water temperature showed an increasing trend (A4, 26.75 ± 0.92); the DO concentration in mg/L was more effective in A2 (2.27 ± 0.81), as opposed to that identified in E5 (1.50 ± 0.36). Finally, it was observed that the growth of the population agglomeration occurred in A2, A3 and A4, associated with the deficiency of basic sanitation, the three component parameters of water quality, act directly and indirectly, in the concentration of non-ionized or free ammonia, which causes problems to the Paragominas stream and the lack of information about this, determines an inefficient management regarding the quality of water in this tributary, on the right bank, of the Uraim River.
