In this study, the contents of steroid hormones and micro-substances in 5 salt-water fishes including Sea-horse, White hering, Garrupa, Selachian and Mackerel were studied. The result demonstrated that: the contents of steroid hormones in 5 mentioned fishes were relatively higher than other salt-water creatures. The study also explored the availability as well as contents of some necessary micro-substances in these salt-water fishes (K, Ca, Cu, Fe, Zn, Mn, Se). Although, the ability of using the active elements in the 5 salt-water fishes as medicines to enhance health and prevent diseases is very potential, it needs further studies

A study of intervention solutions for the exhaust from 4 thermo-electrical kilns, from synthetic process of in NH3 and dust due to NPK fertilizer production was carried out to evaluate the efficacy of technological improvement solutions in reducing environment pollution. Results: concentration of dust and toxic fumes was reduced, concentration of the exhaust components eliminated to environment through the chimneys of gases-made kilns reduced significantly after changing technology. NH3, CH4, H2 from producing NH3 decreased clearly, dust from producing NPK reduced 1.63-1.92 times
