“…Alterations in growth rates are induced by contaminants and the explanation is the reallocation of energy to detoxification mechanisms, depleting reserves that were originally destined for growth. Linde-Arias et al (2008) reported that significant higher CF values were verified in reference sites than in other areas, with evidences of less environmental stress in fish from the reference site. Additionally, fish inhabiting chronically contaminated habitats can develop resistance to pollutant (Elskus, Monosson, Mcelroy, Stegman, & Woltering, 1999;Nacci et al, 1999;Brammell, Price, Birge, & Elskus, 2004).…”

“…It has a long history of pollution and human interference that last for more than 400 years. The river watershed is composed of large urban areas, pasture, sugar cane, steel and textile, metallurgic, cellulose, petrochemical industries (Carvalho & Torres, 2002;Linde-Arias, Inacio, Novo, Albuquerque, & Moreira, 2008;Parente et al, 2015). Furthermore, rice crops and other agricultural activities that require pesticides are taking place in flooding areas of the medium course of the river.…”

ABSTRACT. Biomarkers are measurements within an organism that respond to environmental effects and are used as tools in bioassessment programs since they reflect physiological changes induced by exposure to pollutants. The hepatosomatic index (HSI) and the condition factor (CF) in three fish species Geophagus brasiliensis, Hypostomus affinis and Hypostomus auroguttatus were used to assess effects of pollutant stress in a tropical river during two seasons (dry and wet). Fish from the least disturbed sites had the lowest condition factor (CF) and the lowest HSI, whereas those from sites near pollutant discharges had the highest CF and HSI. Higher HSI and lower CF occurred during the dry season. It is suggested that species adapted to stressful conditions take advantage on food availability from organic loads or unoccupied niches by lesser tolerant species, increasing CF. We concluded that higher HSI values were directly associated with environmental stress whereas the higher CF values are related to availability of food resources derived from organic loads or other sources. CF and HSI are simple and cost-effective, thus suitable as routine screening tools in pollution monitoring, but caution should be taken in relating changes in physiological measurements and any specific pollutant to prevent misinterpretation.Keywords: condition factor, hepatosomatic index, fishes, monitoring, rivers.O uso de biomarcadores para avaliar efeitos de estresses de poluentes sobre espécies de peixes em um rio tropical no sudeste do Brasil RESUMO. Biomarcadores são medidas dentro de um organismo que respondem a efeitos ambientais e são utilizadas em programas de bioavaliação, já que refletem alterações fisiológicas induzidas pela exposição a poluentes. O índice hepatossomático (IHS) e o fator de condição (FC) das espécies Geophagus brasiliensis, Hypostomus affinis e Hypostomus auroguttatus foram calculados em um rio tropical durante duas estações (seca e cheia). Peixes de locais menos alterados apresentaram menores FC e IHS, enquanto os de locais próximos de descargas de poluentes apresentaram maiores FC e IHS. Maiores IHS e menores FC ocorreram durante a estação seca, comparados com a estação chuvosa. É sugerido que espécies adaptadas às condições estressantes levam vantagem da disponibilidade de alimentos próxima às descargas orgânicas ou nichos não ocupados por espécies menos tolerantes, aumentado o FC. Os valores mais elevados do IHS foram diretamente associados ao estresse ambiental, enquanto os valores mais elevados FC estão relacionados com a disponibilidade de recursos alimentares derivados de descargas orgânicas ou outras fontes. FC e IHS são simples e de baixo custo, portanto, adequados como ferramentas no controle da poluição, mas cuidados devem ser tomados ao relacionar suas mudanças às medições fisiológicas ou a qualquer poluente específico para evitar efeitos de interferência.Palavras-chave: fator de condição, índice hepatossomático, peixes, monitoramento, rios.

“…Idealmente, as enzimas selecionadas como indicadores ambientais ( VAN DER OOST et al, 2003) devem possuir as seguintes características: quantificação facilmente realizável com qualidade e o menor custo possível, resposta sensível à exposição ao agrotóxico, possuir padrão de comportamento definido referente à variabilidade natural dentro da espécie avaliada em um determinado nível trófico, tempo e dose de exposição ao poluente bem como possuir significância toxicológica entre a sua resposta e o impacto no organismo. Dados de literatura mostram a importância do uso de multiindicadores em peixes na avaliação do impacto da poluição em rios (LINDE-ARIAS et al, 2008).…”

A agricultura sustentável prioriza o uso racional da terra e da biota. Para tanto, é necessária a compreensão da interação entre os insumos agrícolas e os ecossistemas. Porém, há carência de métodos de fácil acesso para a verificação de contaminação ambiental por muitos desses produtos, como os agrotóxicos e de suas misturas. A aplicação de métodos alternativos no monitoramento de áreas degradadas pode gerar vantagens econômicas quando comparados à implementação de protocolos de análise que utilizam métodos de alto custo que demandam maior tempo de análise. Uma vez que a saúde ambiental pode ser avaliada por meio de estudos com indicadores biológicos, a abordagem aqui apresentada objetiva discutir alguns aspectos a respeito do monitoramento de risco ambiental com organismos não-alvo sentinela, focando parâmetros bioquímicos. Tais parâmetros evidenciariam que o agrotóxico penetrou no organismo e ocasionou uma resposta a um efeito de acordo com a dose ou o tempo de exposição. Esses parâmetros poderão ser utilizados como indicadores biológicos bioquímicos em programas de monitoramento ambiental devido à identificação precoce de alterações. Os resultados obtidos de seu uso poderão ser utilizados para subsidiar políticas relacionadas ao gerenciamento de riscos ambientais. Palavras-chave: Agrotóxicos, Árvore de decisão, Enzimas, Indicadores biológicos, Monitoramento ambiental AbstractConceptual study proposal for the integration and management of biochemical markers of environmental contamination use. Sustainable agriculture prioritizes the rational use of land and biota. For this, there is a need for understanding the interaction between the agriculture inputs and the ecosystems. However, there is a lack of easy access methods for verifying environmental contamination due to many of these products, such as pesticides and their mixtures. The application of alternative methods for monitoring degraded areas can generate economic advantages when compared to the implementation of protocols for analysis using high cost methods which demand a longer analysis time. Since environmental health can be accessed through studies using biomarkers, the approach presented here aims to discuss some aspects on the environmental risk monitoring with sentinel non-target organisms, focusing on biochemical parameters. Such parameters showed that the pesticide penetrated into the body and caused a response according to the dose or time of exposition.

“…Aquatic ecosystems are major recipients of pollutants, which can have serious consequences for biota that may not become apparent until changes occur at the population or ecosystem level (Linde-Arias et al 2008). The need to detect and assess the impact of pollutants, particularly when present at low, sublethal concentrations, on environmental quality has led to a range of biological responses being measured in number of different species (Clements 2000;Fent 2004).…”

The pollution of water by heavy metals is one of the most serious problems in the developing countries, where watercourses play important roles in transport and economic activities. The aim of this study was to examine whether Hyposarcus pardalis, a fish species widespread in the freshwater environment in Indonesia could be used as a biomarker for pollution of the environment by metals. To this effect, the concentrations of metallothioneins and metals in the livers and kidneys of Hyposarcus pardalis were measured. In addition, to clarify the relationship between metallothionein concentrations and metal exposure, the concentrations of metallothioneins and metals were determined in the liver and the kidney of fish exposed to 50 and 500 ppb Cu and 500 ppb Mn, compared with those kept in clean water. Sufficient concentrations of metallothionein were detected in fish captured from Lake Rawakalong located in an industrial area in the suburbs of Jakarta. The results of exposure experiments suggested that Hyposarcus pardalis retained a history of pollution in its organs for a long duration, and the metals bound to metallothioneins in the liver and kidney could be replaced with Cu following exposure. In conclusion, the hepatic and renal metallothioneins in Hyposarcus pardalis are a useful candidate biomarker for monitoring heavy metal contamination.
