“…For example, a field study of C . tentans distribution in a heavy metal contaminated lake showed smaller population sizes in the most heavily contaminated sediments (Wentsel et al ., 1977a) . Many laboratory studies of C. tentans survival and growth in sediments contaminated with heavy metals and/or organic compounds have demonstrated decreased survival and/or reduced growth of larvae (e .g ., Wentsel et al ., 1977b ;Cairns et al ., 1984 ;Adams et al ., 1985Adams et al ., , 1986Giesy et al ., 1988Giesy et al ., , 1990Nebeker et al ., 1984aNebeker et al ., , 1988Hoke et al ., 1990 ;West et al ., 1993) .…”

Effects of Chironomus tentans larval growth retardation on adult emergence and ovipositing success: implications for interpreting freshwater sediment bioassays

et al. 1996

A laboratory study was conducted with Chironomus tentans to assess the significance of growth retardation of thirdto fourth-instar larvae over a 10-d test period on long-term survival, adult emergence, and ovipositing success . Data were intended to provide interpretive guidance for the commonly used growth endpoint in 10-d sediment bioassays with C. tentans . Larval growth was controlled by using six feeding levels ranging from 0 .2 to 5 .9 mg dry weight Tetrafin ® fish food per day . Mean 10-d survival was >88% at all feeding levels, but larval growth decreased significantly (p<0 .05) with each decrease in feeding level . Cumulative successful emergence of adult C. tentans decreased significantly with decreasing larval growth . Mean times to emergence always increased with decreasing growth rates and effects were generally more pronounced for females than males . At the lowest 10-d mean growth where successful emergence occurred (0 .27 mg), the times to emergence doubled relative to the times observed at the highest 10-d mean growth (1 .03 mg) . Ten-day larval growth retardation was strongly correlated with reduction in adult emergence success (r2 = 0.96) . Growth retardations >64% resulted in 86-100% reductions in adult emergence . Growth retardation in the range of 35 to 50% equated with comparable percent reductions in adult emergence success . Although fewer females successfully emerged at 10-d growths of 0 .37 and 0 .74 mg relative to the highest 10-d growth (1 .03 mg), ovipositing success of these females did not appear to be adversely affected by either their slower growth rates or their lower mean dry weights (0 .62 and 0 .99 mg, respectively) . Growth of second generation larvae did not appear to be affected by maternal growth rate, but rather appeared to be solely correlated with their own feeding level .

Sublethal effects of heavy metal contaminated sediment on midge larvae (Chironomus tentans)

1977

Chironomid larvae were maintained for 17 days in sediments with various heavy metal levels . The control sediment had levels of 0.6 ppm cadmium, 17 ppm chromium and 77 ppm zinc . The most contaminated sediment had levels of 1030 ppm cadmium, 1640 ppm chromium, and 17300 ppm zinc .The mean length and weight of the larvae from the control sediment were 1 .83 cm and 2 .86 mg. The mean length and weight of larvae from the most contaminated sediment were 0 .82 cm and 0 .20 mg. A linear relationship was found for the square root of length versus metal levels in the sediment .

“…McMurtry (1984) replicated some of the Wentsel et al (1977) assays on sediment avoidance with chironomid larvae but using mixed cultures of predominantly T. tubifex and L. hoffmeisteri collected from Toronto Harbour, Lake Ontario. He showed that addition of Cu or Zn at sublethal doses increased the migration of tubificids from metal treated cores into the surrounding sediment (Table 4.6).…”

The Pollution Biology of Aquatic Oligochaetes

View full text Add to dashboard Cite

This chapter provides a chronological synthesis of the available literature and information on laboratory based studies of aquatic oligochaetes and has been organized into water-only vs. sediment toxicity tests, and acute vs. chronic toxicity tests. Toxicological studies have employed relatively few species. Absence of sediment in tests with aquatic oligochaetes is a source of stress and reduces realism in exposure conditions and most current toxicity work is performed in the presence of sediment. Thus, unless there is a requirement for water-only tests, for interspecies comparison of toxicity of chemical compounds, or for routine control of species sensitivity in laboratory cultures, these tests are considered inappropriate for oligochaete worms in ecological risk assessment. Field populations of several species have been demonstrated to vary genetically, and may have different tolerances to both environmental and anthropogenic stress. This suggests that test organisms should be obtained from cultures of a defined genetic strain, or alternatively the sensitivity of the populations should be intercalibrated with reference toxicants. Oligochaete worms are not uniformly more tolerant to contaminants than other test organisms. Comparative data for worms and other benthic invertebrates show that responses are species-specific and also contaminant-specific. Among the sublethal measurements, sexual reproduction seems to be the most easily standardised and informative endpoint, and has high ecological relevance, since reproductive impairment has the same long-term effect as mortality on the population. Sublethal, shortterm responses such as behavioural responses (avoidance behaviour, sediment reworking and sediment borrowing) need further standardization. In the future, in situ bioassays are promising tools in environmental risk assessment but will require the use of species characteristic of particular habitats or that are suitable for reproduction and toxicity assessment under different environmental conditions.
