“…The NOEC of 12 mg Ni/L for the time trend of the snail population density was therefore the lowest long-term NOEC found in the present study. It is consistent with recent studies that highlight the sensitivity of the snail L. stagnalis to Ni [32,33]. Thus, 12 mg/L was considered to be the study-specific NOEC.…”

The aquatic risk assessment for nickel (Ni) in the European Union is based on chronic species sensitivity distributions and the use of bioavailability models. To test whether a bioavailability-based safe threshold of Ni (the hazardous concentration for 5% of species [HC5]) is protective for aquatic communities, microcosms were exposed to 5 stable Ni treatments (6-96 mg/L) and a control for 4 mo to assess bioaccumulation and effects on phytoplankton, periphyton, zooplankton, and snails. Concentrations of Ni in the periphyton, macrophytes, and snails measured at the end of the exposure period increased in a dose-dependent manner but did not indicate biomagnification. Abundance of phytoplankton and snails decreased in 48 mg Ni/L and 96 mg Ni/L treatments, which may have indirectly affected the abundance of zooplankton and periphyton. Exposure up to 24 mg Ni/L had no adverse effects on algae and zooplankton, whereas the rate of population decline of the snails at 24 mg Ni/L was significantly higher than in the controls. Therefore, the study-specific overall no-observed-adverse-effect concentration (NOAEC) is 12 mg Ni/L. This NOAEC is approximately twice the HC5 derived from a chronic species sensitivity distribution considering the specific water chemistry of the microcosm by means of bioavailability models. Thus, the present study provides support to the protectiveness of the bioavailability-normalized HC5 for freshwater communities.

“…The Guadalquivir River basin was particularly affected by this element. An excess of Ni have been found to affect survival of algae (Eisler, 1998;Muyssen et al, 2004) and also of some freshwater gastropod species (Peters et al, 2014;Niyogi et al, 2014). The toxicity of Cu and Zn, can be explained by their bactericidal and antimicrobial nature affecting the enzymatic systems.…”

The determination of the real toxicity of sediments in aquatic ecosystems is challenging and necessary for an appropriate risk assessment. Different approaches have been developed and applied over the last several decades. Currently, the joint implementation of chemical, ecological and toxicological tools is recommended for an appropriate and successful toxicity risk assessment. We chose the combination of the toxic unit approach with acute pore water tests (Vibrio fischeri, Pseudokirchneriella subcapitata and Daphnia magna) and whole-sediment exposure tests (V. fischeri, Chironomus riparius), together with invertebrate community composition (multivariate analyses) to detect short and long-term responses of the organisms in four rivers of the Iberian Peninsula. High toxicity was detected in three sites (the downstream sites of the Llobregat and the Júcar, and the most upstream site of the Ebro). We identified organophosphate insecticides and metals as the main variables responsible for this toxicity, particularly in the whole-sediment tests. In particular, chlorpyrifos was mostly responsible for the toxicity (TUs) of D. magna, coinciding with the C. riparius mortality (long-term toxicity) in the mentioned sites, and copper was the main pollutant responsible for the short-term toxicity of P. subcapitata. The combination of the different approaches allowed us to detect ecotoxicological effects in organisms and identify the main contributors to the toxicity in these multi-stressed rivers.

“…exposed to 0.8 μM to 59 μM Ni 2+ [241,242]. In L. stagnalis , soft tissue [Mg 2+ ] decreased after acute and chronic exposures to 8 μM and 0.29 μM Ni 2+ , respectively [242,243]. These observations suggest the presence of an Mg 2+ transporter similar to those found in prokaryotes.…”

Anthropogenic sources increase freshwater salinity and produce differences in constituent ions compared with natural waters. Moreover, ions differ in physiological roles and concentrations in intracellular and extracellular fluids. Four freshwater taxa groups are compared, to investigate similarities and differences in ion transport processes and what ion transport mechanisms suggest about the toxicity of these or other ions in freshwater. Although differences exist, many ion transporters are functionally similar and may belong to evolutionarily conserved protein families. For example, the Na+/H+-exchanger in teleost fish differs from the H+/2Na+ (or Ca2+)-exchanger in crustaceans. In osmoregulation, Na+ and Cl− predominate. Stenohaline freshwater animals hyperregulate until they are no longer able to maintain hypertonic extracellular Na+ and Cl− concentrations with increasing salinity and become isotonic. Toxic effects of K+ are related to ionoregulation and volume regulation. The ionic balance between intracellular and extracellular fluids is maintained by Na+/K+-adenosine triphosphatase (ATPase), but details are lacking on apical K+ transporters. Elevated H+ affects the maintenance of internal Na+ by Na+/H+ exchange; elevated HCO3− inhibits Cl− uptake. The uptake of Mg2+ occurs by the gills or intestine, but details are lacking on Mg2+ transporters. In unionid gills, SO42− is actively transported, but most epithelia are generally impermeant to SO42−. Transporters of Ca2+ maintain homeostasis of dissolved Ca2+. More integration of physiology with toxicology is needed to fully understand freshwater ion effects.
