“…At the same time, other elements, such as Te and Bi, are of several times less interest among users of 877 and 308 articles on the toxic effect of Bi and Te on the soil over the same period. The ecotoxicity of chromium in terms of biological indicators was assessed according to several works (Ahmad et al, 2021 ; Fan et al 2021a , 2021b ; Kolesnikov et al, 2009 , 2014 ). According to the data of previous studies on the toxicity of Ag and Bi, its toxic effect on ordinary chernozem was proved even at a dose of 4.4 and 8.5 mg/kg (Kolesnikov et al, 2020 ; Sudina et al, 2021 ).…”

“…In plant roots, the content of elements varied: they were 0.53 mg Ge and 8.66 mg Si in Z. mays , 0.77 mg Ge and 17.77 mg Si in P. arundinacea and 0.07 mg Ge and 2.64 mg Si in A. sativa , respectively. The content of organic matter in the soil affects the mobility of Ge and its biological properties in the soil (Moschner et al, 2020 ; Fan et al 2021a , 2021b ; Kaiser et al 2020 ). High levels of Ge atoms show low toxicity in the environment, and Ge oxides, like GeO 2 , are highly toxic (Rosenberg, 2009 ; Chen and Lin 2011 ).…”

The content of various chemical elements such as metals, metalloids, and nonmetals in the environment is associated with natural and anthropogenic sources. It is necessary to normalize the content of metals, metalloids, and nonmetals as potentially toxic elements (PTE) in the Haplic Chernozem. The soils of the Southern Russia are of high quality and fertility. However, this type of soil, like Haplic Chernozem, is subject to contamination with a wide range of PTE. The aim of the work was to rank metals, metalloids, and nonmetals by ecotoxicity in Haplic Chernozem. To assess the ecotoxicity of chernozem, data for 15 years (2005–2020) were used. Biological indicators used to assess the ecotoxicity of Haplic Chernozem: catalase activity, cellulolytic activity, number of bacteria, Azotobacter spp. abundance, to change of length of radish’s roots. Based on these biological indicators, an integral indicator of the state of Haplic Chernozem was calculated. The ecotoxicity of 23 metals (Cd, Hg, Pb, Cr, Cu, Zn, Ni, Co, Mo, Mn, Ba, Sr, Sn, V, W, Ag, Bi, Ga, Nb, Sc, Tl, Y, Yb), 5 metalloids (B, As, Ge, Sb, Te) and 2 nonmetals (F, Se) as priority pollutants. It is proposed to distinguish three hazard classes of metals, metalloids, and nonmetals to Haplic Chernozem: I class — Te, Ag, Se, Cr, Bi, Ge, Sn, Tl, Hg, Yb, W, Cd; II class — As, Co, Sc, Sb, Cu, Ni, B, Nb, Pb, Ga; III class — Sr, Y, Mo, Zn, V, Ba, Mn, F. It is advisable to use the results of the study for predictive assessment of the impact of metals, metalloids, and nonmetals on the ecological state of the soil during pollution.

“…Broccoli samples were cultivated and harvested at the Wenzhou Academy of Agricultural Sciences, located in Tengqiao town (longitude: 120.51 • E, latitude: 28.06 • N, altitude: 10 m). The planted fields featured cyanoge clay soil, a predominant soil type for triplecropping paddy fields in southern Zhejiang Province [21]. A total of 191 genotypes of broccoli, obtained through mating crosses over the past decade, were selected for this study.…”

Glucosinolates (GSLs), crucial secondary metabolites in cruciferous vegetables, hydrolyze upon consumption or mechanical damage, forming bioactive compounds with anti-cancer properties, such as glucoraphanin (GRA). Among cruciferous vegetables, broccoli stands out for its high GSL content, which varies significantly among different genotypes. This study aimed to characterize and quantify glucosinolate compounds in broccoli using LC-HRMS2 and UPLC. We identified thirteen GSLs in 191 broccoli genotypes, including seven aliphatic, five indole, and one aromatic glucosinolate. The GSL content in these genotypes ranged from 0.1705 to 5.8174 mg/g (DW). We also explored GSL diversity and content in seven developmental organs, finding high diversity and content in seedling roots and florets. Notably, genotype No. 300 had the highest GSL content (5.8174 mg/g, DW) and GRA (3.1545 mg/g, DW), along with a larger flower bulb diameter (13.4 cm) and a shorter growth stage (11 days), demonstrating its potential for breeding GRA-rich broccoli. To our knowledge, this study encompasses the largest number of broccoli genotypes to date, broadening our understanding of GSLs’ diversity and content in broccoli. These findings may provide valuable resources for future breeding or the commercial cultivation of GRA-rich broccoli.
