This research was focused on the eco-friendly treatment of deep-sea mining tailings in the sea areas and mainly dealt with evaluating the optimal conditions by comparing aluminum sulfate (AS), which had been proven recently to have an effect as a heavy metal extractant, with ethylenediaminetetraacetic acid (EDTA) in terms of environmental and economic feasibility.

Bioaccessibility of lead (Pb) and cadmium (Cd) was conducted in soil samples collected from a dirt road that connects a former Pb and zinc (Zn) beneficiation and smelting plant in the city of Adrianópolis (Paraná state, southern Brazil). Samples were taken in three sites (beneficiation plant, slag deposit, and near Adrianópolis downtown).

As a carbon-negative emission technology, biochar has attracted extensive attention for application in fields for soil improvement and pollution control. The interactions between biochar and soil cadmium via the coupling of physical and chemical processes with extensive application and the correlation between the speciation of soil heavy metals and bioavailability are current research hotspots.

The environment has undergone significant change because of technological advancement. Industries are releasing pollutants directly into the environment. Water pollution is a growing issue for humanity. Methods for managing wastewater generated by biological and industrial wastes are being developed. Textile industries are risking the health of living beings by contaminating water with dyes. Azo dyes are the major constituent of wastewater from textile industries.

Heavy metal pollution is one of the ever-increasing environmental issues that has aroused wide public concern.

Soil Pb extractability and critical Pb levels in soils were examined for three leafy vegetables grown in artificially Pb-contaminated soils at different Pb concentrations in a greenhouse experiment. Soil Pb extractability was quantified using eight extractants, and the Pb concentration was determined in two different parts of the leafy vegetables (edible parts and roots).

The residues of pharmaceutical compounds such as nonsteroidal anti-inflammatory drugs in aquatic environments are a matter of global concern because they may pose deleterious risks to human health and ecosystems. In this study, a novel composite was prepared by grafting ionic liquid hypercrosslinked polymer onto the surface of the melamine sponge skeleton. The resultant hypercrosslinked polymer@sponge was characterized using SEM, BET, FT-IR, TG-DSC, XPS, and a zeta potential analyzer.

Heavy metal accumulation in soil and water is one of major problems. The existence of large amounts of heavy metals in agricultural soils has impacted the food security significantly and, by extension, the human health. Recognition and as a new approach, the use of natural zeolite in soils can be very effective in polluted area.

With the large-scale use of plastic products in daily life and the progress of industrial production, it has had a serious impact on the soil environment. To identify the effect of heavy metal and microplastics on the development of plants, we examined the changes of physiological and biochemical indexes of Brassica chinensis var. chinensis under different concentrations of heavy metal cadmium and polyethylene stress with a pot experiment.

Aim of this work was to synthesize mercapto-modified attapulgite (ATP-SH) and explore the effectiveness and mechanism of ATP-SH on the remediation of Cd-contaminated soil. The ATP-SH was applied to the remediation of cadmium contaminated soil with a concentration of 5.48 mg/kg through pot rice experiment. The changes of soil physicochemical properties, Cd content in rice and straw, available Cd, and different speciation of Cd in soil were studied after the addition of ATP-SH.

This study evaluated the seasonal and spatial variations in the presence of Giardia and Cryptosporidium in rural drinking water supply systems of different municipalities of Antioquia. The municipalities evaluated were Envigado, Caldas, Sabaneta, La Estrella, Itagüi, Bello, Barbosa, Copacabana, and Girardota, located in the department of Antioquia, Colombia.

Long-term monitoring is required to assess the current state and trend of water quality in anthropogenic-influenced estuarine systems. In this study, we evaluated 1581 samples from a 27-year time series (1990–2016) of physicochemical parameters, microbiological, and heavy metals in the surface waters of the Santa Cruz estuarine channel, Brazil.

Arsenic (As) is very common pollutant of the environment categorized as class-I human carcinogen. Rice crop is inherently efficient at accumulating As that is also triggered by conventional cropping methods (flooded conditions).

Cd(II) pollution in water will cause serious threats to the environment and human health. The general remediation protocol for Cd(II) pollution by hydroxide (Ca(OH)2 or NaOH) is still faced with filtering difficulties and high effluent pH.

Enhanced phytoextraction of metals using amendments and hyperaccumulator plants is a promising alternative to expensive traditional remediation techniques. The present study comprehensively investigated the effects of six amendments on both mobility and phytoextraction of Cd and the feasibility of integrating amendment with Ramie as a hyperaccumulator plant on Cd-contaminated soil remediation.

During the last decade, alkali-activated aluminosilicates (fly ash, metakaolin, or blast furnace slag) or geopolymers have been investigated for their ability to immobilize wastes containing highly soluble oxyanionic metals of chromium (Cr), arsenic (As), and antimony (Sb). Effective stabilization of these metal anions was perceived as a challenging issue since they are not liable for precipitation or balancing the negatively charged Al tetrahedra of geopolymer.

Cadmium (Cd) contamination threatens the safety of rice and seriously endangers human health. In plot and field experiments, the effect of combined silicon (Si) and calcium (Ca) application on Cd toxicity and accumulation by rice was investigated in low and moderately Cd-contaminated paddy soils. Two types of Si fertilizers, limestone, and novel composite soil amendment (Si + Ca) were soil-applied before rice planting.

Saline-alkali is one of the important environmental factors affecting oil-contaminated soil.

Microbially induced carbonate precipitation (MICP), a type of urease-based biomineralization, has been a well-researched technique in recent years for heavy metal immobilization; however, the efficiency of the process remains in question. Poly(amino acids) are known to enhance enzymatic activity.

Metal(oid)s contamination in agricultural soils can create adverse environmental conditions and pose human health risks. The present study was conducted to assess metal(oid)s contents, source identification, and ecological and health risks due to metal(oid)s contamination in BISIC industrial region soils of Tangail district Bangladesh.

The integrated management of water resources is a requirement for environmental preservation and economic development, with the removal of nutrients being one of the main drawbacks.

Arsenic (As) is a soil contaminant with important interactions with the soil microbial community. Upon contamination, soil microbes can display metabolic changes, which can be measured through the profiling of their potential for the oxidation of organic substrates. The present study aimed to evaluate the microbial metabolic profile in soil samples containing different forms of inorganic As (AsIII and AsV) in a 360-day experiment.

Solanum nigrum (S. nigrum), a newly discovered Cd-hyperaccumulator, has attracted the attention of many scholars. The present experiment was aimed to explore the difference of Cd accumulation ability among different S. nigrum genotypes and reveal the underlying mechanism. Three different genotypes of S.

Due to high mercury and arsenic toxicity, post-mining Hg-As-contaminated sites can cause varied and complex environmental and health problems. The aim of the study was to demonstrate the significance of the health risk assessment tool for remediation of post-mining soil contaminated with Hg and As.

Water is a vital resource to every living thing on the earth. Once the water is contaminated (physically, chemically, biologically, or radiologically), it brought negative impacts to the living thing. This paper provides a brief review of the characterization of biological pollutants in drinking water and their effects on human health.
