Abstract:
Sediment constitutes an important sink of endocrine disruptor compounds; however, the potential of sediments to act as a source of endocrine disruptors should be more extensively investigated. The main objective of this study was to determine whether exposure of immature common carp to Uruguay River sediments undergo physiological and endocrine alterations. The lower Uruguay River watershed supports intensive agricultural and forest production, receives municipal sewage discharge and industrial effluent, and a new large pulp mill was constructed in 2006. A 30-day semi-static assay was performed using sediments from four sites along the Uruguay River and compared with an unexposed group in dechlorinated water as a negative control. We focused on two upstream and two downstream sites of a new elemental chlorine free pulp mill. The results showed that plasma vitellogenin levels increased in fish along the river and significant differences were found between the exposed and unexposed groups. Condition factor and gonadosomatic index were not different; however, a significant difference in hepatosomatic index was observed in fish exposed to sediment from an industrial site. A significant reduction in primary spermatocyte accumulation was observed in the exposed group compared with that in the control group, and some individuals exposed to sediments from industrial sites presented with testis?ova. Our results suggest that Uruguay River sediments act as an important source of estrogenic compounds that could be responsible for the alterations observed. Future studies are needed to identify the causal agents and determine exposure routes. MenosAbstract:

El gorgojo del eucalipto, Gonipterus scutellatus Gyllenhal, es un Curculionidae originario del sud-este australiano específico de Eucalyptus spp. El primer país fuera de Australia donde se registró su presencia fue en Sudáfrica en 1916 desde donde el gorgojo inició una rápida expansión y colonizó en apenas 30 años la mitad del continente africano, desde el Cabo de Buena Esperanza al Lago Victoria, a una velocidad de unos 100 km/año. En Sudamérica ha sido descrito en los siguientes
países: Argentina (1926), Uruguay (1943), Brasil (1955) y Chile (1998). Las larvas y los adultos de G. scutellatus se alimentan del follaje de eucalipto en crecimiento. El crecimiento de las poblaciones del gorgojo en pocos años se favorece con la abundancia de hospedantes preferidos, así como condiciones de clima templado, especialmente temperatura y precipitaciones, y ausencia o muy baja presencia de enemigos naturales. El alto potencial reproductivo del insecto, junto con su capacidad de defoliación intensa puede causar pérdidas de crecimiento o deformaciones; incluso los árboles pueden morir debido a infestaciones continuas (no observados en Uruguay). |
