“…The concentrations of dissolved metals in the water samples were determined with a GFAAS, VARIAN SpectrAA220 atomic absorption spectrometer, injecting directly the sample into the detection system with flame atomic absorption spectroscopy (FAAS). Graphite furnace analysis (GFAAS) was used for samples with readings below the limit of detection for FAAS (Páez-Osuna et al, 2015). Pb and Cd were not detected with GFAAS even after concentration of 1 L sample on NH4OH-pretreated Chelex 100 columns and elution with 40 mL of HNO3 (2 M).…”

The aim of this work was to determine the amounts of copper, zinc, cadmium and lead which enter the tanks of the maternity section of a Mexican commercial hatchery, and those that are discharged to the environment. The most important inputs of Cu were chemicals for water treatment and disease prevention, feeds and the metal dissolved in influent water. Suspended solids and feeds were the two most important inputs of Zn, and feeds and chemicals were the main sources of Pb and Cd. Most metal concentrations may be considered safe for shrimp culture, but the concentrations of Cd of three formulated diets were close or above safe levels. The annual 2013 output of this hatchery was approximately 1.3x109 post-larvae, and the estimated metals discharged to the environment by the maternity section were 351 g of Cu, 1,190 g of Zn and 1.35 and 0.02 g of Pb and Cd, respectively. The amounts of Pb and Cd are equivalent to those of the fertilizers spread on between 0.5 and 1.5 ha of the agricultural land of Sinaloa State.

During January 2013, a mining spill occurred in the Santa Maria mining region, releasing around 300,000 m3 of tailings on Los Remedios river, which was transported through the San Lorenzo river and finally to El Comedero (EC) dam. Twenty months later, we examined the concentrations of Hg and Se in the muscle, liver, gills, and guts of three fish species (Cyprinus carpio, Oreochromis aureus, Micropterus salmoides) captured in the EC dam to assess the performance of the cleaning operations. A high Se concentration in the liver of all species (carp, 1.2 ± 0.4; tilapia, 3.9 ± 2.1; bass, 3.5 ± 1.1 µg g−1 ww) was consistently observed, while this behavior was only found in the blue tilapia for Hg (0.15 ± 0.11 µg g−1 ww). Tilapia (benthic-detritivorous) exhibited the highest Se concentrations compared to the carp (omnivore) and the largemouth bass (piscivore). In contrast, the largemouth bass had the highest Hg levels in the muscle compared with the other fishes. Such differences could be related to the different metabolism and feeding habits among species. Compared to a tilapia study carried out three months after the mine spill during a mortality event, a decrease was evident in the liver for Se and Hg by 7.2 and 4.7 times, respectively. This reveals that cleaning operations were more efficient for Se and less for Hg, and that a prolonged period was required for the partial recovery of the element levels in fish from sites impacted by mining. Considering the Mexican consumption scenarios for each fish species, it could be concluded that there will be no non-cancer risk by exposure to Hg or Se.

“…Large companies store the mine tailings behind dammed impoundments, often termed as tailing ponds or tailing dams (Kossoff et al 2014). Unfortunately, the frequency of dam failures is high resulting in both economic and environmental issues (Páez-Osuna et al 2015, Schoenberger 2016, Jain and Das 2017.…”

The present study describes the incorporation of mine tailings from the silver mine La Guitarra in the manufacture of lightweight prefabricated panels (LPPs). Tailings have concentrations of heavy metals below the maximum permissible levels according to Mexican regulations. Their acidity potential (AP) of 2.22 kg of CaCO3 per tailings ton, along with their lack of neutralization potential (NP), indicates a possibility for the generation of acid mine drainage (AMD). It was reported that concrete could be employed to prevent AMD, thus we proposed to stabilize mine tailings with different concrete ratios and employ these mixtures to fabricate concrete panels. To obtain lightweight panels, a foaming agent was added to the tailings/concrete mixture. Then, a fiberglass mesh was employed to reinforce the final structure. The resulting LPPs (dimensions: 254 × 139.7 × 12.7 mm) showed a flexural strength of 5.80 ± 0.06 MPa, bulk density of 712 ± 104 kg/m 3 , thermal conductivity of 0.159 ± 0.004 W/m K, mass water absorption of 59 ± 10 %, and net neutralization potential (NNP = NP/AP) > 1.2. According to Mexican regulations, these LPPs are not potential generators of AMD.Palabras clave: reuso de jal de mina, concreto celular, concreto reforzado con fibra. RESUMENEl presente estudio describe la incorporación de jales mineros de la mina de plata La Guitarra en la fabricación de paneles prefabricados ligeros (PPL). Estos jales tienen concentraciones de metales pesados inferiores al límite máximo permisible de acuerdo con la normatividad mexicana. Sin embargo, su potencial de acidez (PA) de 2.22 kg de CaCO3 por tonelada de jal, aunado a la ausencia de potencial de neutralización (PN), indica que pueden generar drenaje ácido. Se ha informado que el concreto se puede utilizar para prevenir la generación de drenaje ácido, por lo que se propuso estabilizar los jales mineros con diferentes proporciones de concreto y emplear estas mezclas para fabricar paneles de concreto. Para obtener paneles ligeros se añadió un agente espumante a la mezcla de jales/concreto y se utilizó una malla de fibra de vidrio para reforzar la estructura final. Los PPL resultantes (dimensiones: 254 × 139.7 × 12.7 mm)
