“…Heavy metals, nitrites and organic pollutants in contaminated water and soil could increase the potential risk of cancers (Montesano and Hall, 2001;Hansen et al, 2003;Galiani et al, 2005;Wild et al, 2006;He, 2013). It is reported that contaminated water and food could even increase the morbidity and mortality of cancers, especially digestive cancers (Baudouin et al, 2002;Boffetta, 2006;Beaumont et al, 2008;El-Tawil, 2010;Gallagher et al, 2010;Ebenstein, 2012;Gao et al, 2012;Sun et al, 2014;Zhang et al, 2014;Zhao et al, 2014).…”

Impacts of Soil and Water Pollution on Food Safety and Health Risks in China AbstractEnvironmental pollution and food safety are two of the most important issues of our time. Soil and water pollution, in particular, have historically impacted on food safety which represents an important threat to human health. Nowhere has that situation been more complex and challenging than in China, where a combination of pollution and an increasing food safety risk have affected a large part of the population. Water scarcity, pesticide over-application, and chemical pollutants are considered to be the most important factors impacting on food safety in China. Inadequate quantity and quality of surface water resources in China have led to the long-term use of waste-water irrigation to fulfill the water requirements for agricultural production. In some regions this has caused serious agricultural land and food pollution, especially for heavy metals. It is important, therefore, that issues threatening food safety such as combined pesticide residues and heavy metal pollution are addressed to reduce risks to human health. The increasing negative effects on food safety from water and soil pollution have put more people at risk of carcinogenic diseases, potentially contributing to 'cancer villages' which appear to correlate strongly with the main food producing areas. Currently in China, food safety policies are not integrated with soil and water pollution management policies. Here, a comprehensive map of both soil and water pollution threats to food safety in China is presented and integrated policies addressing soil and water pollution for achieving food safety are suggested to provide a holistic approach.

“…As groundwater N mainly originates from soil leaching, high groundwater N concentration is often observed in areas dominated by agriculture (Di & Cameron, 2002;Gao et al, 2012). The Taihu Lake region (TLR) is one of the most intensive agricultural regions and the most economically developed areas in China (Zhu & Chen, 2002).…”

To evaluate the risk of nitrate (NO3−‐N) in groundwater, it is necessary to know the denitrification capacity. In this study, observations were carried out for 2 years to investigate the groundwater denitrification capacity below three arable land systems in eastern China. Denitrification capacity was assessed by measuring the concentration and distribution patterns of nitrous oxide (N2O) and dinitrogen (N2) in groundwater. The results revealed that groundwater denitrification activity was high and consumed 76%, 83%, and 65% of the NO3−‐N in the vineyard (VY), vegetable field (VF), and paddy field (PF), respectively. The high denitrification activity might be attributed to the strong reducing conditions, with high dissolved carbon concentrations in groundwater, which promotes denitrification. During the sampling period, we observed high dinitrogen (excess N2) accumulation in groundwater, which exceeded the total reactive nitrogen (N) in the deep layer. The large amount of excess N2 observed in VY and VF indicated that considerable N was stored as gaseous N2 in groundwater and should not be ignored when balancing N budgets in aquifers where denitrification is high.

“…The use of herbaceous legumes as green manure and as a source of elite biofertiliser strains for plant growth promotion can be regarded as sustainable agriculture. The use of inorganic fertilisers has been associated with greenhouse gas emission and pollution of underground water resources, particularly nitrate pollution (Gao et al, 2012). Polycultures using legumes are known to reduce pest population pressure on crops, thereby reducing the use of chemical pesticides (Amoako-Atta et al, 1983).…”

Diversity of wild herbaceous legumes in Southern Africa, their associated root nodule bacteria, and insect pests. In: Climate change and adaptive land management in southern Africa -assessments, changes, challenges, and solutions (ed. by Revermann, R., Krewenka, K.M., Schmiedel, U., Olwoch, J.M., Helmschrot, J. & Jürgens, N.) Abstract: Climate change models predict that most parts of southern Africa including Botswana and Namibia will experience severe water stress and temperature increases as a result of climate change. Wild drought-tolerant nitrogen-fi xing plants with heat-tolerant bacterial symbionts might be a source for mitigation, nutrient-rich grazing grounds, and soil fertility. Herbaceous legumes may be developed into forage plants that are resilient to climate change eff ects. Therefore, the purpose of the study was to assess the diversity of wild herbaceous legumes in the north-western and eastern parts of Botswana, northern parts of Namibia, and Northern Cape of South Africa. They were assessed for nodulation and insect damage, root nodule bacteria were isolated, and some were identifi ed and authenticated on their homologous hosts. In Namibia, rhizosphere bacteria were isolated and characterised. For the fi rst time, it was shown that a wide range of wild legumes in the study area were nodulated.
