Environmental Science & Technology, Год журнала: 2024, Номер 58(26), С. 11637 - 11648

Опубликована: Июнь 1, 2024

Lithium (Li) is an important resource that drives sustainable mobility and renewable energy. Its demand projected to continue increase in the coming decades. However, risk of Li pollution has also emerged as a global concern. Here, we investigated characteristics, sources, exposure levels, associated health risks Jinjiang River basin, largest area for Li2CO3 production China. Our results revealed dominant role extraction activities river, with over 95% dissolved downstream river water being emitted from this source. Moreover, concentration aquatic plants (i.e., hyacinth) animals fish) significantly increased upstream areas, indicating significant local ecosystems. More importantly, our study found residents were suffering potential chronic noncarcinogenic primarily consuming contaminated vegetables. We characteristics elements present ores (e.g., Rb, Cs, Ni, F–). By uncovering remarkable impact on content ecosystems first time, emphasizes importance evaluating Li-related industrial activities, including mining, extraction, recovery.

Evaluation of the lithium resource in the Smackover Formation brines of southern Arkansas using machine learning

Science Advances, Год журнала: 2024, Номер 10(39)

Опубликована: Сен. 27, 2024

Global demand for lithium, the primary component of lithium-ion batteries, greatly exceeds known supplies, and this imbalance is expected to increase as world transitions away from fossil fuel energy sources. High concentrations lithium in brines have been observed Smackover Formation southern Arkansas (>400 milligrams per liter). We used published newly collected brine concentration data train a random forest machine-learning model using geologic, geochemical, temperature explanatory variables create map predicted across Arkansas. Using these maps with reservoir parameters geologic information, we calculated that there are 5.1 19 million tons Arkansas, which represents 35 136% current US resource estimate. Based on calculations, 2022, 5000 dissolved were brought surface within waste streams oil, gas, bromine industries.

Lithium is a naturally occurring element in drinking water and commonly used as mood-stabilizing medication. Although clinical studies have reported associations between receiving lithium treatment reduced cancer risk among patients with bipolar disorder, to our knowledge, the association environmental exposure has never been studied general population.

Lithium Removal From Drinking Water

AWWA Water Science, Год журнала: 2025, Номер 7(1)

Опубликована: Янв. 1, 2025

ABSTRACT Lithium (Li) is listed on the U.S. Environmental Protection Agency's fifth Contaminant Candidate List (CCL 5), and its occurrence in drinking water being quantified under Unregulated Monitoring Rule (UCMR5). Little information available removal from water. The current study evaluated 19 historical pilot‐ full‐scale studies conducted sampling at 13 treatment plants. 32 sites included 3 surface 29 groundwater sources, 8 process categories. Conventional treatment, adsorptive media, biological aerobic manganese filters were not effective removing Li. Cation exchange sometimes achieved Li removal, but removals inconsistent. Lime softening often removed 11%–54% Li, treated typically was > 10 μg/L. RO 90% of although finished concentrations depended blending rates. This fills a critical gap evaluating treatability through existing infrastructure.

The European Union (EU) lags in lithium (Li) production despite having substantial resources pegmatites and rare-metal granites. To address this, the Commission has encouraged Li mining Europe. However, there is limited information about potential environmental human-health impacts associated with from these lithologies. In this study, we assess mobility, solid-phase speciation, vitro bioaccessibility of metal(loid)s by combining a series leaching tests mineralogical analyses on Li-rich ore process samples. Despite relatively high concentrations such as As, Cr, Ni, Zn, laboratory simulating weathering under conditions reveal generally low mobility for most metal(loid)s, much lower than reference thresholds. Lithium, which no threshold values are currently available, exhibits higher (up to ca. 62 mg/kg toxicity characteristic procedure) due greater alterability minerals. Spatially-resolved pH-dependent that primarily hosted sulfides (arsenopyrite, chalcopyrite, sphalerite) chromite. Detailed situ investigations using LA-ICP-MS demonstrate presence traces common silicates (biotite, muscovite) fluorapatite, underscoring complexity metal(loid) speciation materials. oral moderate (< 35 %). Inverse geochemical modeling indicates results dissolution phosphates containing amounts at pH (0.5-2). gastric also stems minerals contents. Non-carcinogenic carcinogenic risk assessments corrected indicate health risks. given knowledge (eco)toxicity, implementing best practices tailing managements warranted limit human exposure.
