“…This is supported by other studies suggesting that a drop in pH may cause greater availability of metals in soils (Salomons et al 1987). In addition, SOM has been reported to be an important soil component for controlling the availability of heavy metals (Kong et al 2014), acting as a major sink for trace metals due to its strong complexing capacity for metallic contaminants (Gao et al 2013). Thus, the organic matter extracted from fossil oil by reapers and groundwater input from nearby fish ponds may be responsible for their higher availability in reclamation habitat as well.…”

Owing to accelerating reclamation activities in the coastal wetland reserves, it is of great importance to analyze the effects of wetland reclamation on heavy metal pollution in these areas. Soil samples were collected from reclamation and natural habitats in Yancheng National Nature Reserve for Coastal Rare Birds in Jiangsu, China to investigate the effects of reclamation on the total amounts, availability, and vertical distribution of seven elemental heavy-metal pollutants. In general, the total amount and availability each element were relatively low in the two habitats and were classified as Bno pollution^. Reclamation was found to significantly increase the total amount of As, Cu, and Zn as well as the pollution degrees of As, Cr, and Zn. The availability of Cu, Pb, Cd, and Cr can also be significantly affected by reclamation. Furthermore, surface-accumulation patterns of the total amounts of these heavy metals could be observed in both habitats, and the availabilities of these elements were higher in deeper soils. Reclamation also had significant impacts on the vertical distribution of Cu, Pb, Cd, and Zn. It is essential to properly monitor nearby aquacultural activities, freshwater irrigation, and traffic pollution during plant harvest to alleviate the negative effects of these human activities.

“…Their low CVs (< 20%) further imply a limited influence from agricultural activities. Similarly, Cd, Cu, and Zn accumulations in greenhouse soils also exist in the Wuwei District and Yellow River Irrigation Region in northwest China [4,34]. However, compared with other regions in China, the mean Cd concentration in the Shouguang greenhouse soils was relatively low, only higher than those in the Nanjing and Wuqing Districts, while Cu and Zn concentrations were higher, except for the Zn in Nanjing and Yunnan (Table 3).…”

The intense management practices in greenhouse production may lead to heavy metal (HM) accumulations in soils. To determine the accumulation characteristics of HM and to evaluate possible HM sources in greenhouse soils, thirty typical greenhouse soil samples were collected in Shouguang District, Shandong Province, China. The results indicate that the Cd, Cu, and Zn concentrations are, respectively, 164.8%, 78.6%, and 123.9% higher than their background values. In the study area, Cd exhibits certain characteristics, such as wide variations in the proportion of its exchangeable form and the highest mobility factor and geo-accumulation index, which are indicative of its high bioavailability and environmental risk. In addition, there is a significant positive correlation between pairs of Cd, P, soil organic carbon, and cultivation age. Combined with principal component analysis, the results indicate the clear effects that agricultural activities have on Cd, Cu, and Zn accumulation. However, Cr, Ni, and Pb have a significant correlation with soil Fe and Al (hydr)-oxides, which indicates that these metals mainly originate from parent materials. This research indicated that long-term intensive fertilization (especially the application of chemical fertilizers and livestock manure) leads to Cd, Cu, and Zn accumulation in greenhouse soils in Shouguang. And the time required to reach the maximum permeable limit in agricultural soils for Cd, Cu, and Zn is 23, 51, and 42 years, respectively, based on their current increasing rates.

“…Also, the mean cadmium concentration in the vegetable soils was 2.8 times higher than in the wheat-maize rotations. Kong et al (2014) reported accumulation of Cd, Cu, Pb and Zn on the top layer of poly-tunnel greenhouse soil due to over application of fertilisers. Natural radionuclides are another source of soil pollutants which are transferred in phosphatic fertilisers during its manufacture process.…”

Agricultural activities are responsible for the deterioration of essential ecosystem services like clean water, air and soil. This literature review has identified a multitude of sources for water quality deterioration and emphasised on agricultural pollution due to excessive use of nutrients particularly nitrogen fertilisers. Through this paper, it has also been attempted to identify the upstream cause of fertiliser-linked water quality degradation issue by the cross-sectoral study of the various drivers of fertiliser use intensity. The synthesis of cause and effect has resulted in broader and deeper understanding of the scope of nutrient management at farm level. The paper advocates embracing an integrated water resource management practice as an instrument to manage provisioning and supporting ecosystem services. The review emphasises to focus on the synergistic effect of various factors consisting of socio-economic, personal, institutional and agro-ecological factors to mitigate the nutrient pollution problem as well as the resilience of natural resources. The understanding of farmer fertiliser use pattern can be pivotal in meeting the challenge of sustainable agro-ecosystems by decreasing the trade-offs and maximising the synergies between various factors.
