Ebook "Environmental remediation technologies for metal-contaminated soils" presents a comprehensive and detailed description of remediation techniques for metal-contaminated soils derived from both natural processes and anthropogenic activities. Using a methodical, step-by-step presentation, the book starts by overviewing the origin of toxicants and the correlated comparative extent of contamination to the environment.

Estuary sediments contain toxic heavy metals which can pollute coastal wetlands. Ba Che river estuary is a coastal wetland with an area of 2,844 ha, which is affected by wastes in Ba Che river water and aquacultures. In this study, the accumulation of heavy metals in the Ba Che river estuary was assessed based on the enrichment factor (EF), the geo-accumulation index (Igeo), and the ecological risk index (RI).

Tomatoes and eggplants are foods that have a lot of nutritional values for humans. Applying farming methods to get good quality products such as being free of pathogenic microorganisms and free of heavy metals needs concerned. In this study, we analyzed cultivation soil and irrigation water samples around tomato and eggplant cultivating areas of farmers who used chemical fertilizers and pesticides.

Due to its rising accumulation in the food chain and ongoing presence in ecosystems, metal contamination has piqued the curiosity of experts from all over the world. Environmentally hazardous heavy metal removal is being pursued utilizing a variety of techniques, such as ion exchange and precipitation, as well as chemical oxidation or reduction, electrochemistry, and filtration.

Heavy metal pollution in soils has attracted an increasing attention around the world in past decades. The contamination of agricultural soils is often a direct or indirect consequence of anthropogenic activities. Such pollutants, particularly heavy metals which are not biologically degraded like many organic pollutants; but tending to accumulated, can endanger public health by being incorporated into the food chain.

Used lead-acid battery recycling activities in Minh Khai handicraft village, Chi Dao commune, Van Lam district, Hung Yen province, Vietnam has markedly increased the lead (Pb) content in paddy soil. Reducing the mobility of lead and lead accumulation in rice plants/plain rice are major priorities to reduce the impacts of lead in paddy soil.

Heavy metal pollution of agricultural soils resulting from wastewater irrigation has been causing major concern due to the potential risk involved. In the present study, food-crops (Chrysanthemum coronarium; Ocimum basilicum; Coriandrum sativum), irrigation water, and corresponding agricultural soil were assessed for Pb and As contamination.

The results show that different heavy metal(loid)s in the shoot tissue had different seasonal variation patterns. Seasonal shoot cutting-regrowth did not markedly affect the accumulation of various heavy metal(loid)s in the shoots. The concentration of shoot-borne heavy metal(loid)s was below the maximum tolerable level set for cattle except for Cd during spring-summer.

Due to anthropogenic activity, most vulture species are threatened. Neophron percnopterus, the Egyptian vulture, is a vulture species with a declining population. One of the most important factors threatening the species is exposure to chemicals. The second largest population of this bird species is found in Turkey. Accumulation of heavy metals for this species has not been investigated. The aim of this study was to detect and measure As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn values in the feathers of Neophron percnopterus.

Haliaeetus albicilla is a top raptor that can be used as a model for contaminants transfer in trophic chain. In this study we studied the accumulation of three contaminants on feathers from breeding individuals of white-tailed sea-eagle collected between 2012 and 2018 in the Danube Delta Biosphere Reserve and its surroundings. The concentrations of two heavy metals (chromium, cadmium) and one metalloid (arsenic) were determined by inductively coupled mass spectrometry. Chromium concentrations ranged from 0.32 to 1.33 mg/kg for juveniles and between 0.68 to 2.

In this study, the adult male B. polychresta as a model to evaluate the exposure risks in soil insects inhabiting three different agricultural locations. The HMs concentration and contamination indices within the soil and beetles from study sites were assessed. Moreover, the enzymatic changes and TPc were evaluated in the beetle tissue (gut, fat body, and testis) in these sites. Furthermore, we check the possible relationship interactions between enzyme activities; against HMs accumulation in the whole body tissue of beetles.

Heavy metals are hazardous pollutants for humans, animals and plants, when their threshold concentration exceeds. Tobacco can accumulate higher concentrations of heavy metals, and the genotypic differences of tobacco in heavy metal uptake and their growth responses have not been clearly examined. In this study, the effects of nickel (Ni) and lead (Pb) on phytoremediation capabilities were tested in four local Oriental tobacco cultivars (Basma, Akhisar, Sarıbağlar and Dibek).

Environmental toxicity from non-essential heavy metals such as cadmium (Cd), which is released from human activities and other environmental causes, is rapidly increasing. Wheat can accumulate high levels of Cd in edible tissues, which poses a major hazard to human health.

The recent release of the reference genome sequence assembly of flax, a self-pollinated crop with 15 chromosome pairs, into chromosome-scale pseudomolecules enables the characterization of gene families. The ABC transporter and HMA gene families are important in the control of cadmium (Cd) accumulation in crops.

In the present study, A.flavus and A.fumigatus isolated from pulp and paper mill sludge showed tolerance and accumulation of toxic metals from synthetic medium and paper mill effluent. Effect of heavy metal ions on fungal growth in terms of their biomass (dry weight) was determined and conformed energetic fungal growth after increasing the concentration of Pb2+ and Zn2+ point out the importance of these two fungi for bioremediation.

The major problem in peri urban areas is the poor quality of irrigation water since the waste from all sources is disposed in the rivers and other water bodies. This result in accumulation of heavy metals like Zinc Sulphate (ZnSO4), Cadmium Sulphate (CdSO4) and Copper Sulphate (CuSO4) in the water source has adverse effect on seed germination, Plant growth, and human health.
