    • Water, Air, & Soil Pollution
    • Lead (Pb) is one of the greatly toxic heavy metals that can enter into the biological system through food chain and induce serious health impairments. Lead ion (Pb (II)) can be released in the environment through natural and anthropogenic sources. Among different types of remediation techniques, adsorption is one of the most well-accepted techniques due to its economic feasibility and versatility as well.

  11. Integrated Assessment of Cd-contaminated Paddy Soil with Application of Combined Ameliorants: A Three-Year Field Study

    • Thu, 06/24/2021 - 02:02
    • Bulletin of Environmental Contamination and Toxicology
    • Cadmium accumulation in rice is a major source of Cd exposure in humans worldwide. A three-year field experiment was conducted to investigate the ecological safety and long-term stability of biochar combined with lime or silicon fertilizer for Cd immobilization in a polluted rice paddy. The results showed that the application of combined ameliorants could reduce the Cd content in brown rice to meet the Chinese maximum permissible limit for Cd content in food products (0.2 mg/kg).

    • Wed, 06/23/2021 - 02:01
    • Bulletin of Environmental Contamination and Toxicology
    • It was observed in this work that application of Pb and B[a]P co-exposure significantly (p < 0.05) reduced Pb content in ryegrass leaves and roots. The effect of Pb dominated the change of N, P, K, Cu, and Cr content in leaves and roots of ryegrass under joint stress of Pb and B[a]P. Principal component analysis showed that the foliar spraying of 400 μmol L−1 Pb and 80 μmol L−1 B[a]P had the best effect on improving the mineral element absorption under combined pollution.

  16. Strong evidence for the continued contribution of lead deposited during the 20th century to the atmospheric environment in London of today

    • Tue, 06/22/2021 - 08:02
    • Proceedings of the National Academy of Sciences
    • Although leaded gasoline was banned at the end of the last century, lead (Pb) remains significantly enriched in airborne particles in large cities. The remobilization of historical Pb deposited in soils from atmospheric removal has been suggested as an important source providing evidence for the hypothetical long-term persistency of lead, and possibly other pollutants, in the urban environment.

    • Mon, 06/21/2021 - 02:02
    • Water, Air, & Soil Pollution
    • Today, various methods such as bioleaching are increasingly used to remove toxic and reuse useful metals from low-grade ores and tailings. Bioleaching is an ecologically based technique carried by iron or sulfur-oxidizing bacteria, which convert insoluble metal sulfide to soluble metal sulfate. The purpose of this study was to test and compare two different methods, including Flask and Column experiments, to remove Zinc, Copper, Arsenic, and Iron.

    • To reduce waste volumes and recover valuable products, char was synthesized via co-pyrolysis of rice straw (RS) with spent tires, sulfur wastes, and CO2. The inclusion of wastes and CO2 in pyrolysis of RS was hypothesized to enhance the sorption ability of char for various contaminants, including 2,4-dinitrotoluene (DNT), 2,4-dichlorophenol (DCP), lead, barium, chromate (CrO42−), and selenate (SeO42−).

    • Journal of Agricultural and Food Chemistry
    • In this study, the rhodamine 6G hydrazide (R6GH) complex was synthesized to develop an “off–on” output platform for fluorescence and visual dual-mode analysis of lead(II) (Pb2+). The prepared R6GH complex using the heat to reflux reaction of rhodamine 6G (R6G) and hydrazine hydrate was characterized through FT-IR, MS, 1H NMR, and 13C NMR and demonstrated to have good fluorescence stability and reversibility. The microenvironment for Pb2+ detection has been optimized in detail.

    • Toxicology and Industrial Health
    • Cadmium (Cd) is a heavy metal that is widely present in modern industrial production. It is a known, highly toxic environmental endocrine disruptor. Long-term exposure to Cd can cause varying degrees of damage to the liver, kidney, and reproductive system of organisms, especially the male reproductive system. This study aimed to explore the mechanism of Cd toxicity in the male reproductive system during puberty.
