“…Dollaghan were observed by anglers in the kill zone in late 2007 and would have provided an immediate recolonisation source, facilitating the strong recovery of 0+ trout densities in late 2008. Recovery of fish populations after disturbance tends to be more rapid if the mortality event occurs shortly before reproductive periods (Crunkilton & Duchrow 1990; Meade 2004).…”

A severe fish kill event caused by agricultural pollution impacted 2.4 km of the River Blackwater, Northern Ireland, in August 2007. A post‐kill monitoring programme sampled existing monitoring sites in the fish kill zone as well as upstream and downstream control sites. Post‐kill monitoring in combination with historical background data facilitated an assessment of the extent and severity of the disturbance episode on local salmonid populations. Subsequent recovery patterns indicated that total salmonid abundance returned to control levels within 1 year. Total salmonid biomass recovered within 2 years, whereas brown trout age structure took up to 3 years to return to background levels. Recovery dynamics were dominated by large‐scale directional migrations rather than random local movements. This included an initial autumnal immigration of 0+ age class brown trout, Salmo trutta L., in late 2007 followed by spawning migrations of adult migratory salmonids. The significance of relatively rapid natural recovery patterns is discussed in the context of potential management options such as restocking.

“…After addition of the oil, only temperature and pH were estimated every 24 hours during the experimental period using pH tapes and analogue thermometers. According to Crunkilton and Duchrow (1990), the presence of oil in the water column does not significantly alter levels of dissolved oxygen and conductivity in streams.…”

“…These studies in natural environments or in mesocosms attribute this positive relationship between the larvae and the concentration of oil to the loss of macrophytes coupled with the increase of benthic algae and, thus, more detritus would favour the Chironomidae species. Another explanation for the situation in the natural environment would be the depletion of predators in the presence of oil and the consequent increase in the population of benthic organisms (Crunkilton and Duchrow, 1990). Only two studies evaluating the effect of oil derived from petroleum on aquatic macroinvetebrates have been performed in the Amazon (Couceiro et al, 2006(Couceiro et al, , 2007.…”

“…Larvae of species in the family Chironomidae (Diptera) represent one of the most abundant aquatic insects in most ecosystems, and they have demonstrated their importance as test organisms for studies on risk assessment of substances such as pesticides (Taenzler et al, 2007), heavy metals (Watts and Pascoe, 1996;Harrahy and Clements, 1997;Bechard et al, 2008) and oil (Rosenberg and Wiens, 1976;Cushman, 1984;Crunkilton and Duchrow, 1990;Hatch and Burton Junior, 1999). However, toxicity studies using petroleum-derived products on animals have only been conducted for Amazonian fish (Veintemilla, 2006;Duarte et al, 2010), there being no studies assessing effects on aquatic insects.…”

Tests of chronic and acute toxicity of crude oil on larvae of Chironomus kiiensis Tokunaga (Diptera: Chironomidae)

The Amazon region, known for its mega-biodiversity, also holds large reserves of petroleum and natural gas. The increasing exploitation of natural gas and crude oil in the Amazon has not been accompanied by studies evaluating the impact of these pollutants on local biological communities, particularly aquatic organisms. The aim of the present study was to determine the values of acute and chronic toxicity of crude oil from Urucu to larvae of Chironomus kiiensis Tokunaga, 1936. The LD50 48h of crude oil for second-instar larvae of C. kiiensis was 26.5 mg/L, and mortality for the majority of concentrations tested was greatest during the first 24 hours of the experiment. The survival of eggs of C. kiiensis exposed to concentrations of crude oil was also evaluated but did not differ significantly among the treatments. Despite the high tolerance observed for the species in the experiments, there is a possibility that in the natural environment the oil interacts with other factors, leading to synergistic effects, so further studies are needed to assess the effects of this pollutant on aquatic insect species.Keywords: petroleum, LC50, Chironomidae, Urucu, Amazon.Teste de toxicidade aguda e crônica de óleo cru em larvas de Chironomus kiiensis Tokunaga (Diptera: Chironomidae) ResumoA região Amazônica, conhecida por sua megabiodiversidade, também é detentora de grandes reservas de petróleo e gás natural.

A sobrevivência dos ovos de C. kiiensis expostos a concentrações de óleo cru também foi avaliada, porém sem diferença significativa entre os tratamentos. Apesar da alta tolerância da espécie observada nos experimentos, em ambiente natural existe a possibilidade do óleo interagir com outros fatores, apresentando efeito sinérgico, e mais estudos avaliando o efeitos deste poluente sobre insetos aquáticos são necessários.Palavras-chave: petróleo, CL50, Chironomidae, Urucu, Amazônia.

“…The hydrodynamic behavior of oil spills in large bodies of water and in the presence of breaking waves is of considerable interest, as it is important for the effectiveness of marine oil spill countermeasures (Crunkilton and Duchrow, 1990;Linden et al, 1987;Potter and Solsberg, 1986). The initial dispersion and penetration of spilled surface oil into the water column is caused by agitation from turbulent surface conditions.…”
