“…In terms of plant species and morphological characteristics, some universal regulars for uptake effect of THMs are also represented in Table . In previous reports, the BCF values of Cd were calculated in root vegetables as 0.570, in leaf vegetables as 0.010–3.100, and in non‐leaf vegetables as 0.029–0.160 . Apparently, the BCFs of Cd were high in root vegetables, followed by leafy and then non‐leaf vegetables .…”

BACKGROUND Toxic heavy metals (THMs) cause severe environmental hazards and threaten human health through various consumption of food stuff. However, little is known of THMs in chestnuts. In this study, the risk assessment and prediction of THMs [lead (Pb), arsenic (As), chromium (Cr), cadmium (Cd) and mercury (Hg)] in chestnuts and growth soils from China were investigated. RESULTS The main detected THMs in chestnuts and growth soils were As and Cd. The total pollution levels of the five THMs (Nemerow pollution indexes, NPIs) were 0.062 and 1.06, respectively. The dietary risks for children were higher than those of adults, especially short‐term non‐carcinogenic risk. The main combined risks from the relationships between THMs were Pb‐Cr (r = 0.85, P < 0.01) in chestnuts and Pb‐As (r = 0.59, P < 0.01) in growth soils. The risk source was found to be the uptake effect of THMs from soil to chestnut, with the highest bioaccumulation factors (BCFs) of Cd (0.254). Several comprehensive risk models were established with the highest coefficient of determination (R2) of 0.79. In addition, the main contribution rates of different soil parameters to comprehensive risk of THMs uptake were 49.8% (Cd), 23.4% (pH), 13.8% (Cr) and 13.0% (organic carbon). CONCLUSION The total pollution levels of THMs fell outside of the safety domain in growth soils. Furthermore, more attention needs to be paid to Cd pollution owing to its low environment background value and high accumulation ability. Three main soil parameters (Cr content, pH, organic carbon) played important roles in the formations and accumulations of THMs in chestnuts. © 2019 Society of Chemical Industry

“…The above described facts suggest that intensive agriculture that greenhouses undergo favored the accumulation and availability of HM in soils, which has been previously described by Gil et al (2004), cropping and management practices. Li et al (2017) found that greenhouse cultivation greatly enhanced the bioconcentration of most metals from soil to plant roots.…”

“…Soil is one of the most important reservoirs of HMs and one of the principal routes of metals uptake in crops. High‐intensity cropping can increase the HM concentration in soil and water, which could affect the content of HM in plants (Li, Shi, Jin, Wu, & Sheng, ; Zhang et al, ). It can potentially affect human health; metals such as Pb and Cd can enter soil via the food chain, exceed normal limits, and have harmful effects (Roy & McDonald, ).…”

Assessing soil contamination and temporal trends of heavy metal contents in greenhouses on semiarid land

et al. 2018

Information about the behavior and temporal evolution of heavy metals in agricultural soils is limited, particularly about greenhouse soils on semiarid lands, indeed it nonexistent. Western Almería (Southern Spain) is a semiarid land where some 30,000 ha are occupied by greenhouses with high productivity. As these greenhouses are fundamental to the socioeconomic development of this area, they should be maintained and well conserved. However, there are indications that long‐term intensive agriculture with considerable agrochemicals use can deteriorate soil quality, which in turn, would reduce productivity and food quality. This study was conducted to investigate soil contamination and the temporal trends of heavy metal concentrations in greenhouse soils of western Almería. Contamination level, availability, and sources of metals were evaluated by the extractable fraction percentage, by indices zinc equivalent, geoaccumulation, enrichment factor and pollution load, and by a correlation analysis between soil properties and metal contents. The results showed that the total contents of Cd, Cu, Ni, and Pb, and the available concentration of Cd, Cu, Pb, and Zn, were significantly higher than background levels. Temporal patterns indicated that these elements accumulate in greenhouse soils. After more than 20 years of intensive agriculture, the available concentration of elements, and contamination, had clearly increased.

“…Some heavy metal absorptions of cucumber and tomato were determined with an experiment carried out under greenhouse and open field conditions (Li et al, 2017). It has been revealed that Cu, Zn, Fe, Mn, Pb and Cd concentrations are higher in the tissues of cucumber and tomato that grew in greenhouse conditions.…”

In this study, the effects of the increasing doses of vermicompost implementation [0 % (VC1), 3 % (VC2), 5 % (VC3), 7 % (VC4)] on some heavy metal contents of cucumber (Cucumis sativus L.) have been investigated. With the increasing doses of vermicompost implementation, Cr, Co, Cd, Ni and Pb contents of cucumber decreased. While the Cr content of cucumber is 65.94 mg/kg with the implementation of VC1 (control) dose, it decreases to 20.58 mg/kg with VC4 dose. The plant's Co, Cd, Ni and Pb contents decreases with the increasing doses of vermicompost implementation, as well, VC1-VC4 doses of vermicompost are determined for Co, Cd, Ni and also Pb as 7.66-2.09, 1.05-0.71, 47.93-14.57 and also 15.68-5.01 mg/kg respectively. These results revealed that vermicompost can be used as a fertilization program to protect the plant's quality and to eliminate its heavy metal contents. On the other hand, the use of organic fertilizers such as vermicompost should be extended for the maintenance of soil productivity.
