“…For example, the sharp increase in hardness between JC6 and JC7 (256 ± 1 to 1018 ± 8 mg CaCO 3 /L) clearly illustrates the effect of lime addition coming from the Copper Cliff Creek input, and JC1 hardness value of 1010 ± 13 mg CaCO 3 /L reflects mining activities from the Garson mine. Observed values for natural hardness in the region are around 50 mg/L, or below [45]. A comparable value was obtained at our site VR considered as a reference (relative to mining pressure).…”

Freshwater Diatoms as Indicators of Combined Long-Term Mining and Urban Stressors in Junction Creek (Ontario, Canada)

Sudbury (Ontario, Canada) has a long mining history that has left the region with a distinctive legacy of environmental impacts. Several actions have been undertaken since the 1970s to rehabilitate this deteriorated environment, in both terrestrial and aquatic ecosystems. Despite a marked increase in environmental health, we show that the Junction Creek system remains under multiple stressors from present and past mining operations, and from urban-related pressures such as municipal wastewater treatment plants, golf courses and stormwater runoff. Water samples have elevated metal concentrations, with values reaching up to 1 mg·L −1 Ni, 40 µg·L −1 Zn, and 0.5 µg·L −1 Cd. The responses of diatoms to stressors were observed at the assemblage level (metal tolerant species, nutrient-loving species), and at the individual level through the presence of teratologies (abnormal diatom frustules). The cumulative criterion unit (CCU) approach was used as a proxy for metal toxicity to aquatic life and suggested elevated potential for toxicity at certain sites. Diatom teratologies were significantly less frequent at sites with CCU values <1, suggesting "background" metal concentrations as compared to sites with higher CCU values. The highest percentages of teratologies were observed at sites presenting multiple types of environmental pressures.

“…In the study by Bubach et al (2015), Se concentrations in the liver of rainbow trout (Oncorhynchus mykiss) were doubled at certain areas, whereas at the same time K, Zn, and Fe did not show significant differences among differently contaminated areas. Increased Se accumulation was also previously reported in several studies in the liver of metal exposed fathead minnows (Pimephales promelas) (Rozon-Ramilo et al, 2011;Ouellet et al, 2013). Various authors have reported different bioaccumulation trends for essential metals at comparable exposure levels (Rozon-Ramilo et al, 2011;Liu et al, 2012;Ouellet et al, 2013), and thus some other factors, and not only the exposure level, probably can influence bioavailability and accumulation of essential metals in fish organs, such as fish species (i.e.…”

“…1 The dusts may be toxic since they may also be contaminated with various toxic metals. For this reason, the prevalence and severity of occupational diseases in the mining industry depends on the ores mined, the contaminants present and also on the levels and duration of exposure and coexisting illnesses in the exposed population and their environmental conditions and lifestyles.…”

“…2 Moreover, the unclaimed ore and spent processing chemicals, known as tailings, 3,4 are discharged into waste streams, which may be an additional source of exposure if not properly contained. 1 Due to policy and legislative reform the techniques for mining in South Africa have improved to include sophisticated ventilation and chemical extraction of minerals from low-grade ores. However, mining in South Africa has the legacy of silica exposure, silicosis and tuberculosis, which contribute substantially to mortality and morbidity of miners.…”

Hazards identified and the need for health risk assessment in the South African mining industry

et al. 2015

Although mining plays a prominent role in the economy of South Africa, it is associated with many chemical hazards. Exposure to dust from mining can lead to many pathological effects depending on mineralogical composition, size, shape and levels and duration of exposure. Mining and processing of minerals also result in occupational exposure to toxic substances such as platinum, chromium, vanadium, manganese, mercury, cyanide and diesel particulate. South Africa has set occupational exposure limits (OELs) for some hazards, but mine workers are still at a risk. Since the hazard posed by a mineral depends on its physiochemical properties, it is recommended that South Africa should not simply adopt OELs from other countries but rather set her own standards based on local toxicity studies. The limits should take into account the issue of mixtures to which workers could be exposed as well as the health status of the workers. The mining industry is also a source of contamination of the environment, due inter alia to the large areas of tailings dams and dumps left behind. Therefore, there is need to develop guidelines for safe land-uses of contaminated lands after mine closure.
