“…Currently, China is evolving its soil contamination policy and is in the process of introducing a more riskbased strategy, one that encompasses a more-cost-effective approach to environmental regulation (Economy and Lieberthal 2007;Luo et al 2009). While, generating suitable management options for heavily contaminated paddy rice soils requires the consideration of technical feasibility and the costs of redevelopment actions.…”

“…Moreover, even if crop cultivation on the most contaminated soils is prohibited, there is still the potential issue of As, Cd, and Pb laden leachates, resulting from theses soils. In UK, a variety of economic and legal incentives are offered to encourage the cleanup and reuse of contaminated sites where there is little prospect of development (Luo et al 2009). Similar schemes are being developed and already a considerable amount of mine-impacted land has been taken out of crop production in the most severely affected regions in Hunan.…”

Purpose Hunan province is well-known for its extensive base-metal extraction and smelting industries. However, the legacies of excavation operations, transportation, and selective smelting activities within Hunan have resulted in the generation of large quantities of mine wastes, which will become the sources of metal contamination in the environment. Thus, there is an increasingly important health issue underlying the study of arable land pollution and transfer of As, Cd, and Pb in the paddy soil-rice system. Materials and methods Paddy soils collected from miningand smelting-impacted areas in Hunan province and rice seed (Oryza sativa L. cv Jia Hua-1) were used for pot experiments under greenhouse conditions. One 30-day-old seedling was transplanted into one pot containing 5.0 kg pretreated soil. At harvest, rice grains and shoots were washed with distilled water to remove surface soil, and oven-dried at 65°C for 96 h until a constant weight was reached. Roots were washed carefully with distilled water for the next process of extracting iron plaque using dithionite-citrate-bicarbonate solution. Total concentrations of As, Cd, and Pb in soil and rice plant tissues were measured by inductively coupled plasma mass spectrometer.Results and discussion Total concentrations of As, Cd, and Pb in the soils collected from 12 mining-and smeltingimpacted areas in Hunan province were much higher than Hunan background values and exceeded the maximum concentration limit for soils set by the Ministry of Environmental Protection. The yields of rice grain from Pb/Zn mining and smelting sites were negatively correlated to overall pollution scores. Distributions of As, Cd, and Pb in rice plant followed: root >> shoot > husk > whole grain. About 30.1-88.1% of As, 11.2-43.5% of Cd, and 14.0-33.9% of Pb were accumulated in iron plaque on root surfaces. Conclusions High concentrations of As, Cd, and Pb are observed in paddy soils from mining-and smeltingimpacted areas in Hunan province, indicating those paddy soils suffer serious combined heavy metal contamination. In particular, Cd is the dominant contaminant followed by As and Pb in paddy soils from most locations. The distributions of As, Cd, and Pb in rice tissue were: root >> shoot > husk > whole grain. Concentrations of Pb in all whole grain and of As and Cd in 50% of whole grain samples exceeded Chinese Hygienic Standard values for food.

“…96/05 of 05/08/1996 is commendable in ushering in a new regulatory policy framework for environmental management in Cameroon, it is very limited in relation to dealing with land contamination, particularly historic contamination and the redevelopment of land which has been affected by historical or existing contamination. Generally, where there is a lack of statutory guidance for the assessment of contaminated land, soil environmental impact assessment is not mandatory for development projects and neither is risk assessment a prerequisite for planning approval (Luo et al, 2009). In such circumstances, as is the case with Cameroon, the investigation and assessment of contaminated land is not considered a significant priority for small and large scale development projects.…”

“…Examples in the context of the Bonaberi Industrial Zone include source characterisation, modelling fate and transport processes along the pathway and the potential effects on the pathways (DEFRA and EA, 2004;Luo et al, 2009). Typically, in Cameroon, efforts at source characterisation have often been limited to assessing bacteriological parameters including bacterial densities, coliform count and streptococcal count which are pathogenic to humans (Akoachere et al, 2008).…”

“…It has been said that the most significant driver of the regeneration of contaminated sites in the UK is the development process, especially for brownfeld sites (Luo et al, 2009). This is likely to be the case in relatively small, but densely populated countries with a high demand for housing provision.…”
