Overview Current and future development of mineral resources requires an evaluation of environmental risks. One challenge in assessing those risks is that drainage from mineralized environments contains multiple metals, each with a unique toxicity to a particular aquatic organism. However, current water quality criteria and risk assessment methods are based on the toxicity of individual metals rather than mixtures of several metals. Hence, new approaches and tools are needed to define the toxicity (or risk) of complex dissolved metal mixtures to aquatic organisms and to aid in the development of new generations of geoenvironmental models for mineral resources and water quality criteria for dissolved metal mixtures. Predicting health impacts of metal mixtures to aquatic biota is an area of current interest to national and international metal industries and regulating agencies.
Nickel and cobalt, two elements found in drainage from platinum group element (PGE) deposits, are of particular interest because the mechanisms by which they cause toxicity are not well known. Previous work developed approaches for predicting the toxicity of metal mixtures to a variety of aquatic organisms (Balistrieri and Mebane, 2014; Balistrieri et al., 2015; Schmidt et al., 2010). In that work, water and biological data from the, biotic ligand models that predict accumulation of multiple metals on organisms, toxicity functions that relate multiple metal accumulation to biological response, and Monte Carlo simulations to predict the probability of health impacts to invertebrates from polymetallic vein and porphyry deposits with various types of hydrothermal alteration was used. This project extends that work by developing similar probability curves for multiple organisms exposed to potentially toxic dissolved metals (cobalt, copper, nickel, and zinc) derived from PGE deposits. Approach Development of probability curves of health impacts to aquatic life from dissolved metal mixtures derived from PGE deposits requires data on the toxicity of cobalt, copper, nickel, and zinc to aquatic organisms and comprehensive water data from areas draining PGE deposits.
