It is suggested that this MLR-based approach, which includes the mechanistic foundation of the BLM but is also consistent with widely accepted hardness-dependent WQC in terms of development and form, may facilitate adoption of updated state-wide Cu criteria that more accurately account for the parameters influencing Cu bioavailability than current hardness-based criteria.

The present review indicates that the stilt field dataset used to establish a frequently cited chronic avian egg selenium threshold of 6 mg/kg dry weight lacks statistical robustness, suggesting that stilt embryo sensitivity to seenium is highly variable or that factors other than selenum are principally responsible for the increase in effects observed at the lower range of this dataset.
Aquatic ecological risks posed by tributyltin in united states surface waters: Pre‐1989 to 1996 data
- R. Cardwell, M. S. Brancato, J. Toll, D. DeForest, L. Tear
- Environmental Science
- 1 March 1999
Tributyltin concentrations in surface waters have declined in all regions and site types since passage of the Organotin Antifouling Paint Control Act in 1988 and no risks of acute toxicity have been suggested since 1994.
Restoration of Freshwater Intertidal Habitat Functions at Spencer Island, Everett, Washington

In November 1994 dikes were breached around Spencer Island, restoring tidal inundation and connections to the Snohomish River estuary, Washington. Approximately 23.7 ha (58.5 ac) of palustrine…
Monitoring Rehabilitation in Temperate North American Estuaries
In this chapter, we propose that monitoring rehabilitation in estuarine ecosystems by necessity requires quantifying relationships between dynamic estuarine processes and sensitive indicators of…
Multiple linear regression models for predicting chronic aluminum toxicity to freshwater aquatic organisms and developing water quality guidelines

- 1 January 2018
Overall, MLR-based models provide a viable approach for deriving Al water quality guidelines that vary as a function of DOC, pH, and hardness conditions and are a significant improvement over bioavailability corrections based on single parameters.
Assessment of Selenium Food Chain Transfer and Critical Exposure Factors for Avian Wildlife Species: Need for Site-Specific Data
Overall, bird-egg residues appear to be the best tool for assessing potential for risk to birds from selenium and the need for the WQC to be set at 2 μg/L to protect aquatic birds is questioned.
Long-term monitoring of arsenic, copper, selenium, and other elements in Great Salt Lake (Utah, USA) surface water, brine shrimp, and brine flies

- 18 February 2015
In brine shrimp, significant differences in annual mean concentrations of As, Cu, and Se were observed using both parametric and nonparametric statistical approaches, but, as for water, there did not appear to be a consistent increase or decrease in concentrations of these elements over time.
Development of Empirical Bioavailability Models for Metals

- 27 December 2019
Empirical bioavailability models often have similar predictive capabilities compared to mechanistic models and can provide a relatively simple, transparent tool for predicting the effects of TMFs on metal bioavailability to achieve desired environmental management goals.
