Lithium Pollution and Its Associated Health Risks in the Largest Lithium Extraction Industrial Area in China

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(26), P. 11637 - 11648

Published: June 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.

Nano-revolution in heavy metal removal: engineered nanomaterials for cleaner water

Frontiers in Environmental Science, Journal Year: 2024, Volume and Issue: 12

Published: May 6, 2024

Engineered nanomaterials have emerged as a promising technology for water treatment, particularly removing heavy metals. Their unique physicochemical properties enable them to adsorb large quantities of metals even at low concentrations. This review explores the efficacy various nanomaterials, including zeolites, polymers, chitosan, metal oxides, and metals, in from under different conditions. Functionalization is strategy enhance their separation, stability, adsorption capacity. Experimental parameters such pH, adsorbent dosage, temperature, contact time, ionic strength significantly influence process. In comparison, engineered show promise remediation, but several challenges exist, aggregation, mechanical strength, long-term performance, scalability. Furthermore, potential environmental health impacts require careful consideration. Future research should focus on addressing these developing sustainable nanomaterial-based remediation strategies. will involve interdisciplinary collaboration, adherence green chemistry principles, comprehensive risk assessments ensure safe effective deployment both lab large-scale levels.

Associations between seminal plasma metals/metalloids and semen quality: A cross-sectional study

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 279, P. 116472 - 116472

Published: May 17, 2024

Exposure to metals/metalloids is reported potentially influence semen quality. While most studies have focused on single metal impacts, the link between exposure multiple metals and quality has remained less explored. The study aimed investigate effects of both individual mixed metal/metalloid A total 330 men were recruited from three reproductive centers in eastern China. Seminal plasma levels 25 sperm parameters determined. We used Generalized Linear Model (GLM) Restricted Cubic Spline (RCS) assess relationships weighted quantile sum (WQS) models then applied evaluate combined effect all these metals/metalloids. observed positive associations lithium (Li), zinc (Zn), magnesium (Mg) with an increased risk below reference values for progressive motility using a logistic regression model (P < 0.05).

Studies on Low-Carbon Designed Adsorbents for Cr(Vi) and Tetracycline Removal: Insight into the Diverse Activation and Adsorption Mechanism

Published: Jan. 1, 2025

It is of great significance to identify adsorption mechanisms for designing low-carbon adsorbents treat complex pollutants. The biochar greatly influenced by its surface functional groups. Various typha biochars activated using KOH (KTBs) and ZnCl2 (ZTBs) through an integrated method exhibited different removal capabilities when treating inorganic (hexavalent chrome) organic (tetracycline) pollution. Specifically, KTBs presented a better efficiency 99.24% TC, while ZTBs superior 99.20% Cr(VI) removal. In conjunction with studies on morphologies adsorbabilities, the were thoroughly investigated XPS density theory (DFT) simulation. TC mainly hydrogen bonding π-π interactions, primarily attributed potential electrostatic attraction groups containing zinc. Based mechanism, CrO42- and/or Cr(OH)3 selectively extracted concentrated from hybrid wastewater simply controlling pH values solution. This novel approach presents new recovering secondary resources desorption processes. study offers feasible synthesizing suitable various specific targets provides effective solution emergency treatment.

Published: July 21, 2023

Azoxystrobin (AZO) is widely used to prevent and treat fungal diseases in important crops but can also impact non-target organisms, including mammals, amphibians, aquatic, soil organisms. Collembolans play roles ecosystems as decomposers, feeders, regulators of microbes. This study aimed investigate the effects AZO on Collembola Folsomia candida using a reproduction test assess biomarker responses over different time intervals (3, 5, 7, 14, 28 days). Results showed negatively affected at concentrations 50, 100, 200 mg./kg, resulting decreases 48.3%, 64.5%, 81.3%, respectively, compared control. Adult survival remained unaffected. The estimated EC50 (reproduction) artificial was 61.28 mg kg−1. Biomarker varied with concentration time. Protein glycogen increased exposure time, while lipid content initially returned control levels by day 28. Oxidative stress biomarkers (CAT, SOD, GST, TBARS) indicated induced oxidative stress, intensifying After days, MDA were significantly elevated control, suggesting antioxidant system overwhelmed which caused damage membranes. that azoxystrobin negative molecular population level species Collembola.
