“…Most heavy metals in freshwater ecosystems complex with organics and are sequestered into the sediments. A recent survey of sediments taken from the Northern Plains in the United States showed that the surface sediments of potholes, rivers and lakes averaged 0.38 mg of Cd per kg dry weight (Jacob et al 2013). Similar levels have been reported in other surveys conducted in the Southeastern United States, China and Central Europe (Cuculic et al 2016; Li et al 2017; Otter et al 2012), although these can be affected dramatically by anthropogenic activity, particularly mining and agriculture (Audry et al 2004; O'Neill et al 2015).…”

“…Sediments in most waterways are also rich in Cd (typically in the range of 0.1 to 0.7 mg/kg dry weight) and the metal enters the food chain via plants and freshwater invertebrates (Cuculic et al 2016; Jacob et al 2013; Li et al 2017; Otter et al 2012). The level currently considered to be safe for human consumption is 7 μg/week/kg body weight (WHO 2004).…”

“…Moreover, the ecological impact of Cd on aquatic ecosystems has not been completely assessed. While Cd is common in sediments (Cuculic et al 2016; Jacob et al 2013; Li et al 2017; Otter et al 2012) where it can enter the food chain, relatively little is understood about the impact of this metal at the low levels at which it is typically found in surface sediments and waters (Burger 2008). There have been relatively few controlled laboratory studies linking environmental levels with physiological function, rather than survival and gross morphology.…”

The longitudinal effects of early developmental cadmium exposure on conditioned place preference and cardiovascular physiology in zebrafish

Cadmium (Cd) is a naturally occurring trace metal that is widely considered to be highly toxic to aquatic organisms and a significant health hazard to humans (Amzal et al 2009; Bernhoft 2013; Burger 2008; Satarug et al 2009). The zebrafish (Danio rerio) has been used as a model organism for toxicological studies with Cd (Banni et al 2011; Blechinger et al 2007; Chow et al 2009; Chow et al 2008; Favorito et al 2011; Kusch et al 2007; Matz et al 2007; Wang & Gallagher 2013). We asked what the lasting longitudinal effects would be from short early developmental Cd exposure (between 24-96 hours post-fertilization) in a range that larvae might experience living atop typical Cd-containing surface sediments (0, 0.01, 0.1, 1.0 and 10 μM CdCl2: 1.124, 11.24, 112.4 and 1124 μg Cd/L). The goal of this exposure window was to specifically target secondary neurogenesis, monoaminergic differentiation and cardiovascular development, without affecting earlier patterning processes. Developmental abnormalities in body size and CNS morphology increased with concentration, but were statistically significant only at the highest concentration used (10 μM). Heart rate for Cd-treated larvae increased with concentration, and was significant even at the lowest concentration used (0.01 μM). Longitudinal survival was significantly lower for fish developmentally exposed to the highest concentration. Except for brain weight, overall morphology was not affected by developmental Cd exposure. However, developmental exposure to lower concentrations of Cd (0.01, 0.1, and 1.0 μM) progressively lowered cocaine-induced conditioned place preference (CPP), used to measure function of the reward pathways in the brain. Baseline heart rate was significantly lower in longitudinal fish developmentally exposed to 1.0 μM Cd. Cardiovascular response to isoproterenol, a potent β-adrenergic agonist, in longitudinal adults was also significantly affected by developmental exposure to Cd at low doses (0.01, 0.1 and 1.0 μM). Surviving longitudinal adult fish exposed to the highest concentration of Cd showed normal CPP and cardiovascular physiology. The data imply that even lower exposure concentrations can potentially result in fitness-affecting parameters without affecting survival in a laboratory setting.

The unique hydrological regime of Three Gorges Dam (TGD) has brought enormous challenges to the riparian zone (RRZ), which plays an important role in regulating sediment and nutrient transport into the Yangtze River. The soil in a RRZ is one of the key factors that affect the water quality. After 4 years of winter‐flooding, the concentration of soil nutrients and potentially toxic metals between the flooded reservoir RRZ and adjacent non‐flooded upland (Upland) are examined. There are two main results: First, soil organic carbon and soil available potassium concentration were significantly lower in RRZ than in Upland. Soil total nitrogen (TN) concentration showed the same trend, but with no significance. Soil available phosphorus concentration is significantly higher in RRZ. Second, the concentrations of all the tested potentially toxic metals (Cd, Cr, Cu, Pb, Zn), their geoaccumulation index (Igeo) values and potential ecological risk index (Ei) values are significantly higher in RRZ than in Upland. Cd had the highest Igeo and Ei values in RRZ. The present results indicated that the flood–dry–flood cycle caused by TGD has changed the soil nutrient concentrations and increased the potentially toxic metal concentrations. There is a cross‐contamination risk of the soil in RRZ, perhaps related to fertilization. As the last protective barrier for the Yangtze River, soil potentially toxic metals pollution control should deserve a considerable attention in the RRZ formed by TGD.

“…Franzen et al (2006) showed Cd concentrations in North Dakota soils varying from 0.01 to 0.31 mg/kg. A survey of wetland soils across North Dakota and northern Minnesota shows that they contain an average of 0.38 mg/kg (Jacob et al 2013). The North American Soil Geochemical Landscapes Project (Smith et al 2009, 2013, 2014; Klassen 2009; Woodruff et al 2009) has released data collected as part of a nationwide geochemical sampling of soils.…”

Purpose Association of element concentrations for the escarpment soils of northeastern North Dakota formed from different geologic parent materials was determined based on geochemical data. These soils overlie the Cretaceous Pierre Formation, and parent materials consist of shale rich glacial till, residual shale, and colluvial materials. Materials and methods Samples were analyzed for cadmium and other trace elements using nitric acid digestion followed by optical emission spectroscopy. Morphologic and laboratory analysis of soil cores indicate high clay content, indicative of the influence of shale residuum on the parent materials of the escarpment soils. Results and discussion An average, cadmium concentration of 0.24±0.22 mg/kg was determined for 136 samples from eight (approx. 2.4 m deep) cores. The concentration of molybdenum had a range between 0.00 and 7.99 mg/kg. Zinc levels determined in the samples had a wide range between 18.76 and 128.02 mg/kg. Principal component analysis revealed that elevated trace element concentrations for the shale-rich portion of the soils in northeastern North Dakota are linked to a variety of factors including organic matter content, pH, elevation, and electrical conductivity. Conclusions Results of this study suggest that erosion and transport of Cretaceous shales downslope on the escarpment have resulted in enriched trace element concentrations in the soils.
