The environmental effect and fate of several agricultural and industrial source toxicants were evaluated in controlled laboratory microcosm systems in the presence of the aminopolysaccharide polymer, chitin. Toxicants examined included methyl parathion, phenol, pentachlorophenol, 2,4 dichlorophenol, 1,2 dichloroethane and Kepone. Microcosm operating parameters, including pH/Eh, salinity, temperature, flow rate and sediment/water interface conditions, were based on comparable in situ measurements. Fate analysis predictions were based on mineralization of the parent toxicant compound as measured by chromatographic analysis or super(14)CO sub(2) expiration. Chitin, amended to continuous flow microcosms, promoted either cometabolic or cooxidative... |

This report intend to know, if BOD5 of fishing industry waste waters,follows a similar and proportional behavior to different temperatures and from incubation times, where the oxidative processes of organic matter are experimentally developed and to obtain a mathematical equation that allows us to know the job stream necessary, when diminishing the experimental time, if we accelerated the processes by means of thermal increases; besides to determine which of the propose methodologies in the bibliography, is the one that explains better the phenomenon of the BOD completes and the deoxygenating constant, important parameters to design any type of system of treatment to the liquid waste waters of the fishing industry. Finding this relation, will be able to be... |

The processing of grapes for the manufacture of juices and wines, generates large quantities of by-products rich in metabolites with antioxidant, antimicrobial, anti-inflammatory and cicatrizing activities. The high homology between human enzymes and snake venoms makes the latter valuable laboratory tools for the study of pathophysiological processes. Proteases and phospholipases A2 act in processes related to hemostasis and inflammatory response. Thus, in this work, dried pomace obtained from grape (Isabel, Niagara, Bordô, BRS Violeta and Blend cultivars) processing were evaluated on phospholipase, proteolytic, hemolytic and thrombolytic activities induced by snakes venoms and the content of phenolic compounds and minerals was evaluated. The dried pomace... |

The major component of tomato processing industry wastes is seed. Samples of tomato (Petomech var.) pomace from industries of São Paulo state submitted to Hot and Cold Break treatments, were spontaneously fermented and washed to separate seeds. The oils were analysed for specific gravity, iodine and saponifícation numbers, refractive index, viscosity and fatty acid composition. Except for saponifícation number, Hot and Cold Break seed oils were very similar. In both treatments palmitic acid was the major saturated fatty acid, followed by stearic acid. Linoleic acid was the major unsaturated fatty acid followed by oleic acid. Both oleic and linoleic acids added up to over 60% of total fatty acids, being higher in Cold Break seed oils. Both treatments... |

لقد تم تطبيق نموذج حسابي لتمثيل تنقل المياه وتسرب المواد الملوثة في بحيرة بنزرت. يتكون النموذج من ثلاثة أبعاد وهو يأخذ في الحسبان تبادل كميات المياه، الأملاح والطاقة بين البحيرة والبيئة المحيطة بها. وفي هذا النموذج مثالي حسابي لتسرب المواد الملوثة اللاتفاعلية. لقد تم تطبيق النموذج لتمثيل تسرب هذه المواد من موقع في جنوب غرب البحيرة ثم في أهم المواقع حول البحيرة. ولقد استعملت الرياح التي قيست والمد والجزر من البحر. لقد أثبتت النتائج ان المواد الملوثة تتبخر في المياه في خلال بضع ساعات. |

The costs related to the construction and maintenance of industrial landfills, and the environmental risks that they may represent, have increased the interest of several types of industries in studying the possibility of applying residues to agricultural soils. This study evaluates the efficiency of flue dust as a zinc source for corn, and the zinc availability for corn evaluated by four methods. A greenhouse experiment carried out at Campinas, SP, Brazil, evaluated the effect of two zinc sources (flue dust and zinc sulphate), at three rates (5, 50 and 150 mg dm-3), in one soil (Rhodic Hapludox) under two pH conditions (5.0 and 6.0). The treatments were arranged in a randomized factorial scheme design with three replications. Zinc availability indexes... |
