“…In New Zealand pastures, an average value of Pb is reported in grass (10.6 mg / kg) with a range of 4.4 to 26.8 mg / kg [27]; observing that the toxicity of Pb causes a decrease in the percentage of germination, growth, dry biomass of roots and shoots, alteration of mineral nutrition, reduction in cell division and inhibition of photosynthesis [43,57].…”

Lead concentration on surface soil (0-20 cm), root and aerial part of natural and cultivated pastures were evaluated, in the rainy season (March 2018), collected in 20 sites of a rural community located 20 km from the La Oroya metallurgical complex , which has been emitting to the environment particulate material with heavy metals since 1922. Lead concentration was determined by flame atomic absorption spectrometry. The data was statistically processed in SPSS 23. Lead levels in the soil, root and aerial part of the cultivated pastures were 224.75 ± 39.41, 169.13 + 58.79 and 20.73 ± 2.52 mg / kg (p <0.01). In natural pastures values were 210.87a ± 40.37, 184.36b + 52.66 and 19.47c ± 3.12 mg / kg (p <0.01). There are no differences between cultivated and natural pastures. Lead transfer factor from soil to root of cultivated and natural pastures was 0.75 and 0.87. Lead transfer factor value from soil to aerial part of cultivated and natural pastures was 0.092 in both. High lead content in soil and aerial part of the pastures used as food for high Andean cattle is a public health problem; livestock products produced in these soils would not be fit for human consumption.

“…The discharge of heavy metals into the environment without any prior treatment is diminishing the water quality to frightening levels, thereby posing its lethal effect on to the living organisms (Martin, Turnbull, Rissmann, & Rieger, 2017). Heavy metals tend to accumulate and concentrate in the living tissues through the food chain, imposing its adverse impact on human health (Etesami, 2018).…”

In this study, a comparative evaluation of floating and submerged macrophytes was performed. Azolla filiculoides (free floating) and Hydrilla verticillata (submerged) aquatic macrophytes were utilized for arsenic, copper, chromium and lead removal from the respective metallic ion solutions. Batch experiments were performed initially with optimization of different physical parameters viz., pH, initial heavy metal concentration, biosorbent dosage, contact time, temperature and agitation speed. Submerged (Hydrilla verticillata) had depicted better removal efficiency in comparison to the floating macrophyte (Azolla filiculoides). Field emission scanning electron microscopy equipped with energy dispersive spectroscopy and Fourier transform infrared spectroscopy analysis was performed for the characterization of the metal loaded biosorbents. Biosorption of the respective heavy metal was clearly depicted in the FESEM-EDX spectrum, although not much change in the morphology of the biosorbents were examined. FTIR spectra of the biosorbents obtained after the experiments confirmed the involvement of C-H bend, -CH 2 -(C=O), N-H, -C-O, R 2 -C= bending and -C-C=O on the biomass. Furthermore, the biosorbent regeneration followed by heavy metal biosorption confirmed the reusability of the prepared biosorbent for at least two consecutive cycles without much significant change in the heavy metal biosorption capacity.

“…Heavy metal contamination is a major concern, because it can lead, for example, to their bioaccumulation in the food chain, which affects human health (Peralta-Videa et al 2009 ), to an inhibition of biodegradation of organic contaminants (Maslin and Maier 2000 ; Alloway 2013 ), to groundwater contamination (Mulligan et al 2001 ), and to reduction of land and food quality (McLaughlin et al 2000 ; Kabata-Pendias 2004 ; Gardea-Torresdey et al 2005 ; Martin et al 2017 ). According to Cicek et al ( 2012 ), pollution from roadways and automobiles is now considered to be one of the largest sources of heavy metals.…”

The purpose of the study was to evaluate the effect of distance from a road on lead and cadmium content in grass species near an expressway and to assess bioaccumulation of these elements by morphological parts of the plants. The material for the research was the following grass species in their flowering stage: Dactylis glomerata, Arrenatherum elatius, and Alopecurus pratensis. Plant samples were collected along the international E30 road, the ring-road of Siedlce, in May 2015. A 9-km road section was examined with samples collected on both sides, covering a stretch of 700 m, at the following distances from the edge of the road: 1, 5, 10, and 15 m. Five samples of each plant species and at each distance from the road were collected. Lead and cadmium concentration was determined with the AAS method. The largest amounts of Pb were absorbed by A. pratensis L. (3.843 mg kg−1DM), while the lowest by A. elatius L. (2.523 mg kg−1DM). Of the above plants, the highest amount of Cd (0.286 mg kg−1DM) was accumulated by D. glomerata L. Underground parts of the grass species accumulated greater amounts of Pb and Cd than aboveground parts. It indicates that considerable amounts of heavy metals released by expressway vehicles contaminated the soil. The highest content of Pb and Cd was found in the grass growing at a distance of 5 m from the edge of the roadway, and this applies both to underground and aboveground parts.
