“…Tetraethyl lead was used as a gasoline additive to increase the octane rating, before the EPA banned its use in gasoline in 1996 in the USA. Leaded gasoline is still used for propeller planes and some race cars [1,19]. Metallic lead is a bluish, gray-silver soft metal.…”

“…It is mostly performed on-site and is widely accepted. Microorganisms and plants use different mechanisms for bioremediation of contaminated water and soils [44,45,46]. The bioremediation process occurs through a variety of mechanisms like redox, adsorption, complexation, ion exchange, precipitation and electrostatic attraction [47].…”

“…In addition, more research is needed that integrates biotechnological approaches with extensive multidisciplinary research to improve plant tolerance and reduce toxic metal deposition in the soil [8,53]. In the agricultural field, phytoremediation, phyto-extraction, phyto-polymerization, phytostabilization, phytodegradation and rhizophilization are effectively used for the removal of heavy metals [45]. Plants also help prevent wind, rain, and groundwater runoff from carrying pollutants from the site to the surrounding areas or deeper underground [46] (Figure 1).…”

Heavy Metals - Their Environmental Impacts and Mitigation

Fast consumption, increasing energy needs, unplanned urbanization, and unconscious discharge of industrial wastes cause pollution of air, soil, food and water resources. Among these pollutants, heavy metals and metalloids are not biodegradable and accumulate in compartments such as water, soil and plants, threatening human and environmental health. Monitoring studies show that heavy metals such as arsenic, lead, mercury, cadmium, nickel, zinc, copper, chromium and trace elements are in first place according to their availability in the environment. Preventive and remedial measures should be taken to reduce the effects of heavy metals. Legal regulations, monitoring studies, the use of soluble and non-toxic compounds in environmental compartments (air, water, soil and plants) in industrial processes, heavy metal-free pesticides, appropriate wastewater treatment plants and use of renewable energy sources instead of fossil fuels are among the priority measures to reduce concentrations of heavy metals in the environment. As a bioremediation approach, removing toxic wastes from the environment by using bioaccumulatory organisms such as plants or mussels maintains its importance among studies aimed at recovery. Studies have shown that integrated methods - especially the combination of suitable plants and microorganisms - are very effective in mitigating the effect of heavy metals in the environment.

“…Outros, contudo, como o cádmio, não apresentam função biológica conhecida, causando sérios problemas devido a sua toxicidade, aliada aos fenômenos de bioacumulação (Dal'corso, 2012;Furini, 2012). A contaminação dos solos agrícolas por metais pesados é uma séria preocupação na atualidade, uma vez que estes são persistentes no solo e facilmente absorvidos e acumulados pelas plantas (Kumar et al, 2019a). O cádmio é introduzido nos solos indiretamente (deposição atmosférica) através de práticas antropogênicas como a mineração, queima de lixo e de combustíveis fósseis.…”

O cádmio é um metal pesado altamente tóxico, com nítidos efeitos nas plantas, podendo interferir em vários processos fisiológicos e causar graves aberrações de desenvolvimento. Este experimento foi realizado nos laboratórios da Universidade Federal da Fronteira Sul, campus Chapecó. O ensaio foi planejado em esquema de parcelas subdivididas no tempo, em delineamento inteiramente casualizado, com classificação cruzada e 4 repetições. Para tanto, as sementes foram divididas em 4 lotes de 16 repetições com 50 sementes e cada repetição foi semeada em substrato de papel para germinação de sementes previamente umedecido com água adicionada de diferentes concentrações de cloreto de cádmio (CdCl2), de modo que as concentrações finais de cádmio fossem 0,0; 25,0; 50,0 e 100,0 mg L-1, gerando quatro tratamentos diferentes. Os rolos de papel foram mantidos em germinadores à temperatura constante de 25ºC, com fotoperíodo constante de 24 horas, e as avaliações (plântulas normais, plântulas anormais, comprimento da raiz primária, comprimento da parte aérea e matéria seca) foram realizadas em 4 repetições de cada tratamento no quarto, quinto, sexto e sétimo dias após a semeadura. A análise de variância (teste F a 5%) foi utilizada para análise das variáveis, sendo que as comparações das médias de cada repetição foram feitas por meio do teste de comparações múltiplas de Tukey ou regressão, ambos a 95% de confiança. Nas doses testadas, o cádmio afetou severamente a germinação das sementes, o desenvolvimento das raízes e tamanho da parte aérea das plântulas e os teores de matéria seca.

“…In particular, soils in the floodplains can store matter, such as carbon, salts, or metals [1,2]. Since many floodplains are used for food production [3,4], metal contamination of soils can be detrimental to human health [5,6]. Studies on metals such as cadmium (Cd), chromium (Cr), nickel (Ni), lead (Pb) and zinc (Zn) have shown that they affect soil biota and can accumulate in plants growing in the soils, potentially entering the human food chain [7][8][9].…”

Metal contamination, especially in river floodplain soils, can have detrimental effects on human health. Much research has been conducted to describe the distribution patterns of metals and the factors involved in these patterns. However, most studies focus on the distribution of individual metals in soils, not on the co-occurrence of metals, and on a selection of metals associated with anthropogenic sources known to have especially severe effects; this had led to a lack of knowledge about many other metals with potentially harmful effects. Therefore, this study aimed to identify the multi-metal distribution patterns of 38 metals in the Sacramento River floodplain and find their controlling factors. We found 484 significant correlations between metal distributions. Less commonly studied metals, such as gallium, lanthanum, scandium, and vanadium, had more than 25 correlations each. In total, 13 individual metal patterns described the spatial distribution of 22 metals. Three multi-metal patterns were extracted, explaining 86.9% of the spatial variation of the individual patterns. The most important factors were the distance to specific streams due to emission and transport processes in their watersheds, and local soil properties. We conclude that multi-metal distribution patterns hold more information than individual metal patterns, contributing to the gathering of information about less commonly sampled metals and allowing more specific source identification.
