“…There is evidence that these substances (PCBs being a case in point) can be toxic to plants, but at levels several orders of magnitude higher than found in soils irrigated with water contaminated by these chemicals (Holoubek et al 2009;Wang et al 2010;Weber and Mrozek 1979). However, these substances are of real concern from the perspective of food safety, as they may reach humans via contaminated foodstuffs of animal origin, particularly seafood (Guo et al 2009;Zhao et al 2006).…”

Future threats to agricultural food production posed by environmental degradation, climate change, and animal and plant diseases – a risk analysis in three economic and climate settings

Global food security is one of the most pressing issues for humanity, and agricultural production is critical for achieving this. The existing analyses of specific threats to agricultural food production seldom bring out the contrasts associated with different levels of economic development and different climatic zones. We therefore investigated the same biophysical threats in three modelled types of countries with different economic and climatic conditions. The threats analysed were environmental degradation, climate change and diseases and pests of animals and plants. These threats were analysed with a methodology enabling the associated risks to be compared. The timeframe was 2012-2050 and the analysis was based on three underlying assumptions for 2050: the world population will have increased to 9 billion people, there will be a larger middle class in the world and climate change will be causing more extreme weather events, higher temperatures and altered precipitation. It is suggested that the risks, presented by the biophysical threats analysed, differ among the three modelled types of countries and that climate zone, public stewardship and economic strength are major determinants of these differences. These determinants are far from evenly spread among the world's major food producers, which implies that diversification of risk monitoring and international assessment of agricultural production is critical for assuring global food security in 2050.

“…Aged activated carbon sorbed up to 10 % more than freshly spiked carbons (Oen et al 2011). Soil parameters affecting desorption of DDT were stated to be % organic matter, amount of dissolved organic carbon, surface area, % clay/silt, and pH levels (Ghazali et al 2010;Holoubek et al 2009;Oen et al 2011;Thangavadivel et al 2011). For instance, relatively low pH values (pH=5.4) were said to cause stronger hydrogen bonding when compared to neutral or alkali pH conditions (Boivin et al 2005;Thangavadivel et al 2011).…”

“…Another adverse effect on human health is that it is an endocrine disruptor and a suspected carcinogen (Fang et al 2012;Holoubek et al 2009; Thomas and Gohil 2011). Experimental studies on animals have shown that DDT and its two most frequently observed metabolites dichlorodiphenyldichloroethylene (DDE) and dichlorodiphenyldichloroethane (DDD) have neurotoxic, carcinogenic, immunotoxic, estrogenic, and reproductive effects (Ghazali et al 2010;Nadeau et al 1998; Van den Berg 2009).…”

“…Both metabolites resemble the overall structure of the parent compound, are hydrophobic, and resistant to degradation. Due to their limited solubility, soil is considered the primary sink for DDT, DDD, and DDE (Doong and Liao 2001;Holoubek et al 2009). DDT contamination that originated in waterways has sediments as the primary sink (Neamtu et al 2009).…”

1,1,1-Trichloro-2,2-bis(p-chlorophenyl)ethane(4,4'-DDT) is a pesticide well-known for its negative health and environmental effects. Despite being banned by a majority of world countries more than 30 years ago, its persistence in the environment is a continuing problem even today. The objective of the study was the investigation of sorption/desorption behavior of 4,4'-DDT in sandy loam soil. The impact of contaminant concentration and age was observed with three different experiments. The sorption percentages at the end of the short time step (8 h) were 50 and 92 %, for initial concentrations 2.26 and 5.28 mg/L, respectively. When freshly spiked soil was subjected to a conventional sorption study, 82 to 99.6 % of the initial aqueous DDT concentrations were sorbed within 24 h. When modeled with a Freundlich isotherm, the log K f was found to be 3.62. After six consecutive 24 h desorption steps, 33 to 96.6 % still remained in the soil. This was more pronounced for soils that had been aged for 60 days. After seven consecutive 24 h desorption steps of aged soil, the percent remaining sorbed to the soil were 44, 64, and 77 %, for 25, 250, and 500 mg/kg, respectively. All results show that 4,4-DDT has a tendency of sorbing to the soil rapidly and showing resistance to desorption. When comparing desorption values, aged soils were seen to desorb less than non-aged soils. This result was attributed to stronger binding to soil with increased contact time.

“…However, the anthropogenic sources of potentially toxic trace elements in agricultural soils include mining, smelting, waste disposal, urban effluent, vehicle exhausts, sewage sludge, pesticides, fertilizers application and so on (Wei and Yang 2010). In an ecological aspect, contamination may have a significant negative impact on soil as habitat for numerous soil organisms and plants (Ayodele and Oluyomi 2011;Boshoff et al 2014;Dalenberg and Driel 1990;Heikens et al 2001;Holoubek et al 2009;Kelepertzis 2014;Martínez-López et al 2014;Notten et al 2005;Weggler et al 2004;Zhang et al 2015).…”

Potentially toxic trace elements (PTEs) may be transferred to plants and consequently enter the food chain. Environmental monitoring of PTEs is important to control their concentrations in the environment and, particularly in farmland soils. The study aims at estimating the concentration of PTEs in the soil, its grass cover and collected soil invertebrates and consequently to investigate the transfer of pollutants in the soil-plant-fauna trophic chain. None of the PTEs was recorded in soil concentrations at levels exceeding the limits defined by the Regulation of the Minister of Environment. Mean concentrations of Zn, Pb, Cd, Ni, and Cu in soil were 55, 52, 44, 23, and 10 % of the permitted values, respectively. The concentrations of potentially toxic trace elements in soil samples were higher compared to their levels in grass, except for Cd which was the other way around. Higher concentration of Cd in grass than in soil may be attributable to direct deposition of metal particulates emitted from motor vehicles on grass, rather than soil along the road. As far as other metals (Pb, Ni, Cu, Zn) are concerned, concentration in soil was higher than in grass, however, lower than in the fauna. In the investigated meadow, both grass cover and the collected soil fauna accumulated cadmium in largest amounts and incorporated the studied metals in the following order:All considered elements showed greater concentrations (nearly tenfold higher for cadmium) in fauna than grasses.
