“…Physical-chemical and major ion concentration in groundwater sampled on riparian and rural properties in the Urupá River basin (Rondônia, Brazil -being a freely mobile ion in the soil water potentially able to reach lower soil layers (groundwater), whereas NH 4 + tends to be retained into the soil by cation exchange processes. 36 In this study, a predominance of nitrate was observed for all samples, since ammonium is generally found in very small concentrations.…”

“…Hooda et al point out that the extent of nitrate leaching in rural areas is strongly influenced by land use, management practices, climate and soil types. 36 Hence, the high intensity of rainfall in the Amazon region in addition to both inadequate well installation and also ruminant excretion through urine and faeces might be influencing significantly higher nitrate concentrations observed near pastures. [37][38][39][40] Dissolved inorganic nitrogen in the riparian forest was very low with …”

Groundwater quality comparison between rural farms and riparian wells in the western Amazon, Brazil

Recebido em 28/10/09; aceito em 30/7/10; publicado na web em 17/11/10Groundwater quality of a riparian forest is compared to wells in surrounding rural areas at Urupá River basin. Groundwater types were calcium bicarbonated at left margin and sodium chloride at right, whereas riparian wells exhibited a combination of both (sodium bicarbonate). Groundwater was mostly solute-depleted with concentrations within permissible limits for human consumption, except for nitrate. Isotopic composition suggests that inorganic carbon in Urupá River is mostly supplied by runoff instead of riparian groundwater. Hence, large pasture areas in addition to narrow riparian forest width in this watershed may have an important contribution in the chemical composition of this river.

“…Water may become polluted with a range of contaminants due to the use of land for agriculture (e.g. Hooda et al 2000;Lovell and Sullivan 2006). Of these pollutants, dissolved organic carbon (Freeman et al 2001;Holden 2005;Wallage et al 2006), nutrients (nitrogen and phosphorus) (Heathwaite et al 1996;Haygarth and Jarvis 2002;Dorioz et al 2006) and pesticides (Environment Agency 1999; Blanchoud et al 2007;Garrod et al 2007) are the most important issues for some land-owning UK water utilities due to the need to remove them from raw water to meet regulatory standards.…”

Although water constitutes 71% of the earth's surface, only 0.3% of it is available as fresh water for human use. Moreover, the quality of fresh water in ground and surface systems is of great concern, as potable water needs to have appropriate mineral content. Ground and surface water quality in rural and urban environments is affected by both natural processes and anthropogenic influences. Because of this, water is becoming scarcer as the population increases across the world. Natural processes leading to changes in water quality include weathering of rocks, evapotranspiration, depositions due to wind, leaching from soil, run-off due to hydrological factors, and biological processes in the aquatic environment. These natural processes cause changes in the pH and alkalinity of the water, and also phosphorus loading, increase in fluoride content and high concentrations of sulphates. Anthropogenic factors affecting water quality include impacts due to agriculture, use of fertilizers, manures and pesticides, animal husbandry activities, inefficient irrigation practices, deforestation of woods, aquaculture, pollution due to industrial effluents and domestic sewage, mining, and recreational activities. These anthropogenic influences cause elevated concentrations of heavy metals, mercury, coliforms and nutrient loads. This paper studies the effects of natural processes and human influences in rural and urban aquatic systems. Pollution due to environmental parameters such as heavy metal pollution, heavy metals and bacterial and pathogenic contamination of both urban and rural areas is discussed in detail.

“…Todavia, para o Conselho Nacional do Meio Ambiente (CONAMA), o limite é de 10 mg L -1 para água doce, ultrapassado nas primeiras lixiviações. No entanto, como foi realizada uma única aplicação de cama de aviário, esses resultados não significam que não haverá contaminação do lençol freático, desde que haja o uso continuado da cama de aviário, como tem sido observado em extensas áreas onde se realiza aplicação intensiva de dejetos animal (Hooda et al, 2000). Dos ácidos orgânicos avaliados, no tratamento sem cama de aviário, apenas o acético foi detectado no lixiviado dos dois solos, mas em concentração muito baixa (em torno de 0,1 mg L -1 ) e apenas na primeira percolação (Figura 6a,b).…”

RESUMOCom o incremento exponencial da avicultura no Brasil, a disponibilidade de dejetos de aves e de cama de aviário tem aumentado de maneira semelhante. A proibição de uso desses produtos na ração animal tem feito com que eles sejam direcionados para a produção agrícola como fertilizantes. Ainda há na literatura carência de informação sobre lixiviação de bases no perfil do solo em conseqüência do efeito de ânions inorgânicos acompanhantes, como cloreto, nitrato e sulfato, e do efeito complexante de ácidos orgânicos de baixa massa molecular. O objetivo deste trabalho foi estudar o efeito da aplicação de cama de aviário na lixiviação de Ca, Mg, K e Na em solos e sua associação com ânions inorgânicos e ácidos orgânicos de baixa molecular. Amostras de dois Latossolos Vermelho-Amarelos, um de textura média e outro de textura argilosa, foram colocadas em colunas de PVC constituídas de cinco anéis, cada um com 10 cm de altura e 5 cm de diâmetro, ligados entre si com fita adesiva. O solo colocado no anel superior recebeu, homogeneamente, cinco tipos de camas de aviário: casca de café, casca de arroz, sabugo de milho,
