“…Of the aquatic invertebrates Plectrocnemia conspersa, Hydropsyche instabilis, and Rhyacophila dorsalis (Trichoptera), Rhithrogena semicolorata, Baetis rhodani, and Leptophlebia marginata (Ephemeroptera), Amphinemura sulcicollis, Isoperla grammatica, and Dinocras cephalotes (Plecoptera), and Gammarus pulex (Amphipoda), only Gammarus showed significant mortality in an acid stream dosed with Al for 24 h (~700 µg · L -1 Al, pH ~4.7, ~60 µM Ca; McCahon et al, 1989). Gammarus infected with an acanthocephalan parasite, Pomphorhynchus laevis (Müller), were more affected than were uninfected animals.…”

“…Gammarus infected with an acanthocephalan parasite, Pomphorhynchus laevis (Müller), were more affected than were uninfected animals. Gammarus and Isoperla showed a linear accumulation of Al with time in a reach of the stream treated with lime, presumably due to Al precipitating from solution or absorbing to particles of lime, which then attached to the invertebrates (McCahon et al, 1989). Liming of the River Audna (Norway) was successful in allowing recolonization by acid-sensitive species of mayflies, stoneflies, and caddis flies (Fjellheim and Raddum, 1992).…”

ABSTRACT:In this article we review the biological effects of Al, primarily with respect to the chemical factors controlling Al bioavailability and toxicity, and how its biological effects are best predicted. Our intent is not to duplicate recent reviews on Al chemistry or toxicity, but rather to update the literature since these reviews were published, and to focus on Al speciation and other external chemical influences on Al bioavailability to freshwater biota. Briefly, we first review Al chemistry, with a specific focus on understanding, as well as measuring, Al chemical species of importance to aquatic biota. Next we more comprehensively review Al toxicity and bioavailability to freshwater algae, with a thorough analysis of the relationships between speciation and toxicity, the role of important chemical complexing agents such as P, Si, and organic carbon, as well as the potential for Al to impact algal community structure. A third section reviews the more sparse literature on aquatic higher plants; the fourth section reviews a somewhat more abundant literature of Al toxicity to freshwater invertebrates. We close with an updated review of Al toxicity to fish, again with a focus on mechanisms of toxicity, and the role of Al speciation in controlling bioavailability.

Episodic acidification affects the breakdown and invertebrate colonisation of oak litter

2012

Summary 1. Although European streams are now recovering chemically from acidification, biological recovery is limited. One hypothesis is that continuing acid episodes restrict acid‐sensitive species in recovering locations either through direct toxicity or by affecting ecological processes. Here, we test this hypothesis by assessing the effects of episodic acid exposure on the breakdown and macroinvertebrate colonisation of oak (Quercus robur) litter. 2. Over 83 days, acid episodes of 4 days’ duration were simulated by repeatedly transplanting litter bags of contrasting mesh size between replicate acidic and circumneutral streams around Llyn Brianne (Wales, U.K.). Results were compared against controls from circumneutral streams and circumneutral transplants, while invertebrates colonising litter were compared with adjacent assemblages. 3. Breakdown was retarded significantly by repeated acid exposure in comparison with circumneutral transplants, but only in litter to which invertebrates had access. Overall breakdown was also significantly slower in fine‐mesh than in coarse‐mesh bags. 4. Plecopteran shredders were the major invertebrate colonists of litter, along with smaller numbers of grazers and predators. However, acid exposure eliminated or suppressed acid‐sensitive families, resulting in an overall composition converging on that in acid streams. 5. The rapid loss of sensitive invertebrates from acid‐exposed litter supports the hypothesis that acid episodes suppress biological recovery from acidification through direct physiological effects. However, our litter breakdown data indicate that (i) some effects of acid episodes could be mediated through litter processing; and (ii) episodic acidification could disrupt litter breakdown through effects on invertebrate composition or activity. These data suggest that delayed biological recovery from acidification can reflect a combination of direct toxic and indirect ecological effects.

“…Karlsson-Norrgren et al (1986a), however, determined the concentrations of aluminum in various organs (gills, kidney, liver, intestine, muscle, and bone) of brown trout in acidified farms. They reported that exposure to aluminum was reflected by relatively high have been many reports on the effect of a high concentration of aluminum in acidic waters on fish, and most have focused on damage and aluminum accumulation in the gills (Karlsson-Norrgren et al 1986a,b;Youson and Neville 1987;McCahon et al 1989;Vuorinen et al 1990;Eeckhaoudt et al 1996). However, the accumulation of aluminum in organs has not been well studied, and it is unclear whether aluminum is taken into the bloodstream and distributed to the body.…”

Aluminum in lake water and in the organs of the fish Tribolodon hakonensis was investigated in Lake Usoriko (pH 3.6), Lake Inawashiroko (pH 5.0), and the Tenryu River (pH 7.7). The concentration of total soluble aluminum in the water was 0.51 mg l Ϫ1 in Usoriko, 0.05 mg l Ϫ1 in Inawashiroko, and less than 0.01 mg l Ϫ1 in the Tenryu. The chemical forms of soluble aluminum in the acid water were characterized as Al 3ϩ , AlL 2ϩ , and AlL Ϲ1ϩ . More than 90% of soluble aluminum in the water of Usoriko was Al 3ϩ , whereas AlL 2ϩ was dominant in the water of Inawashiroko. The aluminum concentration in the organs of T. hakonensis in Usoriko was 42 µg g Ϫ1 wet weight in gills, 4.2 µg g Ϫ1 in muscle, 6.9 µg g Ϫ1 in bone, 12.7 µg g Ϫ1 in liver, 6.0 µg g Ϫ1 in kidney, and 6.0 µg g Ϫ1 in intestine, indicating accumulation of aluminum in the gills. The aluminum concentration in the organs of T. hakonensis living in Inawashiroko was approximately the same, in spite of the difference in water chemistry of the two acid lakes, especially for pH and aluminum. This suggests that aluminum accumulation might be controlled in the fish living in the acid lakes. In contrast, the aluminum concentration in the gills of T. hakonensis from the Tenryu was 2 µg g Ϫ1 .
