“…Unionids have been used as in situ biomonitors of contaminant exposure [1–4]; however, comparatively less is known about their utility as indicators of contaminant effects [5,6]. In the past 10 years, adult unionids have been used to assess the effects of contaminants.…”

We conducted a series of in situ tests to evaluate the effects of pore-water ammonia on juvenile Lampsilis cardium in the St. Croix River (WI, USA). Threats to this river and its associated unionid fauna have accelerated in recent years because of its proximity to Minneapolis-St. Paul, Minnesota, USA. In 2000, caged juveniles were exposed to sediments and overlying water at 12 sites for 10 d. Survival and growth of juveniles was significantly different between sediment (mean, 47%) and water column (mean, 86%) exposures; however, these effects were unrelated to pore-water ammonia. During 2001, juveniles were exposed to sediments for 4, 10, and 28 d. Pore-water ammonia concentrations ranged from 0.3 to 62.0 microg NH3-N/L in sediments and from 0.5 to 140.8 microg NH3-N/L within exposure chambers. Survival (mean, 45, 28, and 41% at 4, 10, and 28 d, respectively) and growth (range, 3-45 microm/d) of juveniles were highly variable and generally unrelated to ammonia concentrations. Although laboratory studies have shown unionids to be quite sensitive to ammonia, further research is needed to identify the route(s) of ammonia exposure in unionids and to understand the factors that contribute to the spatial variability of ammonia in rivers.

“…There are many advantages of using biomonitors. They essentially provide information on the average variation in time and space of the concentrations of contaminants in the surrounding water (Herve et al, 1996;Stewart and Malley, 1997). Also, they can concentrate the water contamination (Stewart and Malley, 1997) making the analyses simpler and cheaper.…”

“…The Brazilian coast has a variety of mussels, and the commercial species Perna perna was chosen for this long-term heavy metal and organochlorinated contamination study. All basic requirements for the preliminary selection of a monitor organism suggested by Stewart and Malley (1997), were met for this species. The behavior of heavy metal bioaccumulation was studied in the mussel P. perna in relation to sex, size, type of substrate, and so on (Rezende and Lacerda, 1986;Furley, 1993).…”

A bleached kraft pulp mill discharges a vast array of substances and special attention should be given to heavy metals and organo-chlorinated compounds. They can persist in nature for a long period of time, are toxic to the wildlife community in certain concentrations, and can be incorporated into the food chain. The aim of this work is to monitor the quality of a bleached kraft pulp mill effluent using filter-feeding molluscs. Transplanted mussels were collected seasonally and analyzed for copper, zinc, cadmium, lead, manganese, iron, dioxins, furans and pentachlorophenol. All of the concentrations in mussels were low even when the mill operated different process types and production, and also during maintenance shut-downs.
