“…The problem of environmental pollution from mercury (Hg) and its effect on human health is currently a global issue . Contamination of the biosphere by Hg is mainly caused by anthropogenic factors, including coal combustion, mining, cement production and chemical industry . When Hg is released into the natural environment, and in groundwater, microorganisms including bacteria are often responsible for the biotransformation of the metal leading to the formation of methylmercury (MeHg) .…”

[3][4][5] When Hg is released into the natural environment, and in groundwater, microorganisms including bacteria are often responsible for the biotransformation of the metal leading to the formation of methylmercury (MeHg). 6,7 Methylmercury and ethylmercury (EtHg) are highly hazardous forms that accumulate in freshwaters, ecosystems and food chains, leading to Hg exposure in people and other natural living organisms.…”

Mercury (Hg), a highly toxic environmental pollutant, shows harmfulness which still represents a big concern for human health, including hazards to fertility and pregnancy outcome. Research has shown that Hg could induce impairments in the reproductive function, cellular deformation of the Leydig cells and the seminiferous tubules, and testicular degeneration as well as abnormal menstrual cycles. Some studies investigated spontaneous abortion and complicated fertility outcome due to occupational Hg exposure. Moreover, there is a relation between inhaled Hg vapour and reproductive outcome. This MiniReview evaluates the hypothesis that exposure to Hg may increase the risk of reduced fertility, spontaneous abortion and congenital deficits or abnormalities.

“…2). The probability of HMs pollution in the urban soils of the mentioned closely related regions supported the idea that pollution does not clearly remain in a one region [4,31]. The HMs pollution in the different soil samples revealed some variations and suggested the natural variability and varied origins of the mentioned metals.…”

“…The main source of the soil pollution was the hazardous wastes produced by industrial activities in the study area and spread all over the region through rainfalls or winds. Wu et al [31] discovered the pollution of traffic-related metals and agricultural wastes. Geochemical approaches combined with multivariate analysis of the concentrations of HMs in the coastal areas of Montenegro demonstrated much higher Cd and Pb contents in the soil samples compared to those of the background area [24].…”

This study presents the importance of urban field soils for producing vegetable crops. This study was conducted in the three local areas of Isfahan (first region), Falavarjan (second region), and Natanz, Feridan, and Golpayegan (third region) to evaluate transfer factor (TF), contamination factor, ecological risk (Er) and potential ecological risk index (RI) which were employed to investigate the Pb, Cu, Co, Cd, and Cr pollution of the urban field soils affecting vegetable to reveal the potential hazards of HMs pollution for the first time in Isfahan city in Iran. To measure the pollution of such heavy metals (HMs) as Pb, Cu, Co, Cd, and Cr, the related soil samples were collected and their pollution and ecological risk indices were assessed. The results showed the highest pollution of Pb and Cr in the field soils of the first (127.37 and 112.65 mg kg −1) and second (6.94 and 4.61 mg kg −1) regions, respectively, which were greater than the amounts recommended by Iran's Environmental Protection Agency. The high TF of Cr (0.56 mg kg −1), Cd (0.23 mg kg −1), and Co (0.30 mg kg −1) from the soils to the tubers were found to mostly involve leafy and fruity vegetables. The highest contamination factor (PF) of Cr (12.46 mg kg −1) in the first region was in the class of very high pollution. The highest Er of Cd in first and second regions was 264.0 and 214.9 mg kg −1 , respectively, which were considered in the high-risk class. These indices revealed possible increases in potential ecological RI in the mentioned regions (up to 330.8 and 272.4 mg kg −1 , respectively), which were classified in the classes of high and moderate pollution risk. Principal component analysis indicated that the pollution of the HMs in Isfahan and Falavarjan was overlapped. Cr in PC1 and Cd and Co in PC2 had the highest distributions and impacts representing enhancing transfer factor from the soils to onions, potatoes, and basil.

“…Recently there has been growing evidence of decreased soil productivity as a result of long-term monoculture of irrigated sugarcane (Saccharum officinarum L.) combined with intensive irrigation and fertilization regimes (Umrit et al, 2014;Yin et al, 2018;Martíni et al, 2020;Ouda, 2020;Wu et al, 2020;Marin et al, 2021). Excessive tilth, irrigation, fertilization and management practices such as trash burning that diminish organic matter and nutrients and soil health have also been recognised as primary factors contributing to the yield decline in sugarcane monoculture systems (Umrit et al, 2014;Wu et al, 2020;Marin et al, 2021). With each other, these management practices give rise to dilapidation of the soil physicochemical, and microbiological properties as evidenced by less soil microbial biomass and enzymatic activity, accrual of detrimental soil organisms, increased accumulation of heavy metals, decreased amounts of SOC, lower soil CEC and pH and increased soil bulk density (Yin et al, 2018;Martíni et al, 2020).…”

Soil deterioration and yield decline are the main factors affecting the environmental sustainability of long-term irrigated sugarcane monoculture. This research was conducted to detect changes of soil physical, chemical and physicochemical quality parameters associated with intensive irrigated sugarcane monoculture with groundwater for long term. Sugarcane monoculture resulted in a severe impact on some soil physical indicators of soil quality as increased the soil bulk density and reduced soil clay content, decreased soil aggregate stability and the water content at the field capacity causing decreases in soil porosity and decline in soil fertility. Significant impacts on some soil chemical indicators of soil quality were also recorded as reduced soil organic matter content and increased soil pH and EC producing soil salinity. Fields under long-term irrigated sugarcane monoculture had low OM values ranged from 2.09 to 2.61% while areas under crop rotation had the highest OM values ranged from 2.62 to 3.39%. Fields under sugarcane monoculture system had higher pH, EC and SAR values ranged from 7.96 to 8.41, from 2.98 to 4.22 dS m -1 and from 7.75 to 11%, while fields under crop rotation system had the lowest pH, EC and SAR values ranged from 7.64 to 7.92, 1.41 to 2.42 dS m -1 and from 4.51 to 5.86%, respectively. From these results, it could be concluded that long term sugarcane monoculture has significantly deteriorated soil physical and chemical properties indicating the urgent demand for more sustainable management practices to preserve soil quality.
