Objetivou-se, com este trabalho, avaliar a influência do lançamento de efluente de um frigorífico de abate de bovinos sobre a qualidade da água do córrego Jurubatuba, Anápolis, GO. Analisaram-se: o efluente tratado antes do lançamento no córrego e a água do córrego 50 m à montante e 50 e 500 m à jusante do ponto de lançamento. Foram realizadas oito coletas no período seco (08/07 a 24/09/09) e oito no chuvoso (01/10 a 03/12/09) quantificando o pH, turbidez, oxigênio dissolvido, saturação de oxigênio, carbono orgânico total, cloro, alumínio, amônia, cobre, manganês, ferro total, fósforo total, sulfeto, sódio, demanda biológica de oxigênio, demanda química de oxigênio, nitrogênio total, condutividade elétrica, nitrato e nitrito. Os valores de pH, NH3-, Zn+, sulfeto, NO3-, e cloreto nos dois períodos e em todos os pontos analisados no córrego, atenderam aos critérios para água de classe 2; o Na+, NH3-, carbono orgânico total, P total, CE e NO3-, aumentaram nos pontos após o lançamento do efluente. A turbidez, Al e o Mg no efluente tratado foram, nos períodos seco e chuvoso, maiores ao permitido para corpos hídricos de classe 2; o Fe total no efluente apresentou risco médio para uso na irrigação.<br>The objective of this study was to evaluate the influence of release of effluent from a cattle slaughter house on water quality of Jurubatuba stream, in Anápolis - Goiás. The treated effluent before release into the stream, the stream water at 50 m upstream, and 50 and 500 m downstream from the launch place were analysed. Eight samples were taken during the dry season (08/07 to 24/09/2009) and eight in the rainy season (01/10 to 03/12/2009), quantifying pH, turbidity, dissolved oxygen, oxygen saturation, total organic carbon, chlorine, aluminum, ammonia, copper, manganese, total iron, total phosphorus, sulfate, sodium, biological oxygen demand, chemical oxygen demand, total nitrogen, electrical conductivity, nitrate and nitrite. The values of pH, NH-3, Zn++, sulfide, NO3, chloride during the two periods at all analyzed points matched the criteria of water of class 2. Na+, NH3, total organic carbon, total P, CE and NO3 increase at some points after the release of the effluent. Turbidity, Al and Mg in the treated effluent during dry and rainy season were higher than allowed for class 2 water bodies; total Fe in the effluent had medium risk for use in irrigation.

Celem opracowania jest analiza współzależności między międzynarodową wymianą produktami rolno-żywnościowymi a poziomem produkcji rolnej w wybranych krajach UE. Badanie oparto na metodologii analizy kointegracyjnej i modelach wektorowej autoregresji (VAR). Znaczenie ekspansji eksportowej dla wzrostu produkcji rolnej jest odmienne w poszczególnych krajach UE. W Polsce produkcja rolna jest kształtowana w znacznej mierze poziomem eksportu, ale pozostaje także pod wpływem własnej tendencji rozwojowej. Polski eksport rolno-spożywczy jest kształtowany własną tendencją rozwojową. Dla Francji nie wykryto współzależności między produkcją rolną i eksportem rolno-żywnościowym. Z drugiej strony, eksport jest kształtowany własną tendencją rozwojową i zidentyfikowano zależność między eksportem i produkcją rolną. Podsumowując, w Polsce eksport wspiera produkcję rolną, a we Francji wysoki poziom produkcji sektora rolnego stymuluje eksport. | The aim of the article is to analyze the interrelationship between the international exchange of agri-food products and the level of the agricultural production in selected EU countries. The study is based on cointegration analysis methodology and employs vector autoregression models (VAR). The relevance of export expansion for the growth of agricultural production differs in individual EU countries. Agricultural production in Poland has a lot to do with the level of the exports, but it is under the influence of its own developmental tendency, as well. The Polish agri-food exports are shaped heavily by their own trend. No interrelationship was detected between agricultural production and agri-food exports in France. On the other hand, exports are influenced by their trend and additionally a strong impact of the level of agricultural production on exports was detected. To conclude, exports support agricultural production in Poland, and the high level of production of the agricultural sector stimulates exports in France. | analiza kointegracyjna ; modele VAR ; produkcja rolna ; eksport rolno-żywnościowy | cointegration analysis ; VAR models ; agricultural production ; agri-food exports | 13 | 248-262 | 1

A partir da comprovação por vários estudos que as sementes de Moringa (Moringa oleifera L.) apresentam a capacidade de clarificar e purificar água potencialmente fora de especificações para consumo humano. Objetivou-se com o presente projeto avaliar se a semente de moringa tem capacidade de purificar água residuária de curtume. Foi utilizada água residuária bruta, coletada antes das estações de tratamento de dois curtumes no município de Maringá, Paraná. As sementes de moringa foram obtidas nos municípios de Umuarama e Floraí, Paraná. As sementes foram retiradas do fruto antes do processo de deiscência e trituradas em meio de água destilada. O sistema foi realizado em sistema descontínuo de tratamento, utilizando vasos de 25litros, onde foram utilizados 15 litros de água residuárias de curtume. Foram feitos uma testemunha e três tratamentos com a mesma concentração 8,0 g L-1 variando a fração em função do tempo de 4, 8 e 12 horas. Foram avaliados os parâmetros: pH, nitrogênio amoniacal, turbidez, DBO e DQO. Os melhores resultados obtidos foram no parâmetro nitrogênio. = The evidence from several studies have indicated that the seeds of Moringa (Moringa oleifera L.) have the ability to clarify and purify water potentially out of specification for human consumption. The objective of this project was to evaluate whether the seeds of moringa are capable of purifying wastewater from tannery. Untreated wastewater was used, collected before entering the treatment plants of two tanneries in the city of Maringá, Paraná, Brazil. The moringa seeds were collected in the municipalities of Umuarama and Floraí, Paraná, Brazil. Seeds were removed from the fruit before dehiscence and crushed within distilled water. The system was carried out in batch processing, using 25-liter pots, and 15 liters of wastewater from the tannery. One control and three treatments were used. All groups contained the same concentration 8.0 g L-1 but were done in 4, 8 and 12 hours. The following parameters were evaluated: pH, ammonia nitrogen, turbidity, BOD and COD. The best results were obtained in the parameter nitrogen.
