“…With the rapid development of industrialization and urbanization, elevated heavy metal contents in built-up lands have been found in many coastal areas around the world [51,52]. However, in this study, the concentrations and pollution levels of heavy metal in built-up areas (LUI-5) were generally lower than those of cultivated and aquaculture lands.…”

Heavy metal pollution in soils and sediments is becoming a matter of wide concern, this study was carried out in Dawa County of the Liaohe River Delta, with the aim of exploring the impacts of land use levels on heavy metal contamination of soil and sediment. A total of 129 soil samples were collected in different land use intensities (LUI). Soil metals (Fe, Mn, Cd, Cr, Cu, Ni, Pb and Zn) and soil salinity, pH, soil organic carbon (SOC), nitrate nitrogen (NO 3 − -N), available phosphorus (AP) and grain sizes were analyzed. Correlation analysis indicated that SOC and grain size played important roles in affecting the heavy metal distribution. The factor analysis results indicated that heavy metal contamination was most probably caused by industrial and agricultural wastewater discharges, domestic sewage discharge and atmospheric deposition. Using ANOVA, it found that human activities significantly changed soil physic-chemical properties through soil erosion, leaching and fertilizer application, further affecting the behaviors of heavy metals in the soil and sediments. The anthropogenic factors could lead to potential environmental risk, as indicated by the Geo-accumulation index (I geo ) results of heavy metals. Overall, the heavy metals generally had approached or even exceeded moderately polluted (0 < I geo < 1, 1 < I geo < 2), but the Pb and Cu pollution level was low (I geo < 0), and the Cd pollution level was moderately or strongly polluted (2 < I geo < 3, 3 < I geo < 4) in the five land use levels. This study will provide valuable information for appropriately determining how land should be used in future reclamation areas, as well as for the sustainable management of estuarine areas around the world.

“…The EFs of the determined PHEs in halophyte land, tideland, and forestland were generally classified as low concentrations group, and that in cropland and aquaculture land were classified as high concentrations group. Similarly, Sowan et al [26] reported that the PHEs contamination in municipality areas, industrial zones, and dockyard were more serious, while shrimp farming and traditional land uses such as salt marshes, paddy fields, orchards, and mangrove forests showed low levels of metals in Pattani Bay. These conclusions proved the intensity of human activity further influenced the soil PHEs enrichment [7,54].…”

“…Soil environmental status of the study area was generally in good condition due to the average concentrations of all PHEs lower than the environmental quality standard for soils in China (Table 3). However, the maximum concentration of some PHEs was close to or exceeded the limits of first grade (As and Pb) and second grade (Cr) of the environmental quality standard, which might be affected by reclamation activities, specifically manifested in the changes of land-use intensity and soil properties [24,26,45]. The traditional evolution pathway of land use in the reclaimed coastal areas in eastern China was mudflat→halophyte land→aquaculture land→arable land→construction land [51], which showed that the land-use intensity gradually increased with the increase of human activity interference.…”

Coastal tidelands are important ecological habitat resources and valuable resources for agricultural land reclamation. Enrichment of potentially harmful elements (PHEs) in soil caused by anthropogenic activity is an important factor implicated in the ecological deterioration of soil in China. A total of 54 soil sample sites were selected from a 30-year reclaimed tideland and an adjoining coastal wetland. Descriptive and multivariate statistical analyses were performed to describe the enrichment, source, health risk status of eight PHEs (As, Co, Cr, Cu, Mn, Ni, Pb, and Zn) after long-term reclamation. Results indicated that after 30 years of reclamation, most soil PHEs are slightly enriched, whereas no serious threat of environmental pollution was observed. In the reclamation area, the enrichment of PHEs in the aquaculture land, industrial land, and cropland was relatively high compared with other land use types, such as tideland and halophyte land. The source analysis divided the PHEs into five categories: (1) Cu; (2) Co and Mn; (3) Cr; (4) As and Pb; (5) Zn and Ni. Cu was completely derived from natural parent materials and other elements were governed by both weathering of parent rock and human activities, including agricultural activities, industrial production, and transportation emissions. The health risk assessment showed that the soil PHEs potentially had no non-carcinogenic risk to the public, but there was an acceptable probability to have cancer due to Cr and As. Meanwhile, children are more susceptible to harm from the PHEs in soil than adults. According to the economic and social development situation in the coastal region, it is necessary to pay attention to the environmental threats of PHEs enrichment.

“…Since trace element contamination in marine sediment is caused by various human activities, the relationship between land use and metal accumulation has also been studied. Sowana et al [ 38 ] reported that Pb levels were higher in residential, industrial, and dockyard areas, and lower in shrimp farms, agricultural land, and mangrove forests. The major sources of Pb in the study area were both natural and anthropogenic.…”

This review summarizes the findings from studies of trace element levels in marine sediment and organisms in the Gulf of Thailand. Spatial and temporal variations in trace element concentrations were observed. Although trace element contamination levels were low, the increased urbanization and agricultural and industrial activities may adversely affect ecosystems and human health. The periodic monitoring of marine environments is recommended in order to minimize human health risks from the consumption of contaminated marine organisms.
