Phytoexclusion of heavy metals using low heavy metal accumulating cultivars: A green technology
2021, Journal of Hazardous MaterialsCitation Excerpt :For example, as shown in Table 3, the individual application of low Cd accumulating cultivars of rice and wheat could meet the required standards in safe growth areas (Chen et al., 2019a, 2019b; Liu et al., 2020). In low-risk growth areas, application of low Cd accumulating cultivars combined with one or two other measures (e.g., appropriate water regimes, liming, and foliar spraying) could reduce the Cd content further in agricultural products and meet the required standards (Guo et al., 2011; Liao et al., 2016; Long et al., 2017). In high-risk growth areas, additional application of soil amendments is essential (Wang et al., 2014a. 2014b; Chen et al., 2019a, 2019b).
Differences in absorption of cadmium and lead among fourteen sweet potato cultivars and health risk assessment
2020, Ecotoxicology and Environmental SafetyCitation Excerpt :In the past decade, these researches typically target single heavy metals, particularly Cd. Low-Cd-accumulation crop species such as rice (Oryza sativa L.) (Zhou et al., 2014; Paulelli et al., 2019), wheat (Triticum aestivum L.) (Liu et al., 2015; Kubo et al., 2016), welsh onion (Allium fistulosum L.) (Li et al., 2012, 2016), maize (Zea mays L.) (Guo et al., 2011; Wang et al., 2016a), sunflower (Helianthus annus) (Laporte et al., 2015; Zehra et al., 2020), and tomato (Solanum lycopersicum) (Hartke et al., 2013; Hussain et al., 2015) have been reported. However, soils are often contaminated with multiple heavy metals.
Effect of inorganic and organic amendments on maize biomass, heavy metals uptake and their availability in calcareous and acidic washed soil
2020, Environmental Technology and InnovationComparative efficacy of organic and inorganic amendments for cadmium and lead immobilization in contaminated soil under rice-wheat cropping system
2019, ChemosphereCitation Excerpt :DEK-1 and GSA-4 (combination of amendments) treated plots exhibited a significant increase in pH, by 0.90 and 0.85 units, respectively, at wheat harvesting. This elevation in soil pH may be in response to hydrolysis of CaCO3 into hydroxyl ions (Guo et al., 2011). Organic manure addition can improve structure and pH-buffering capacity of soil, and enhances metal retention power of soil (Zhang et al., 2016).

2018, Science of the Total EnvironmentCitation Excerpt :As industry and urbanization rapidly developed, there have been various heavy metals that could contaminate the soil through different channels and induce threats to the environment and public health either directly or indirectly (Guo et al., 2011; Zhou et al., 2016; R. Zhou et al., 2017; Y. Zhou et al., 2017; Zhu et al., 2012).
