“…These concentrations of Cd are far higher than those reported in Austria (0.02-0.93 mg/kg DM, Sager 2007), England and Wales (0.19-0.53 mg/kg DM, Nicholson et al 1999). Similar values were also reported in other cities or regions of China (Li et al 2010, Zhang et al 2012. Such high concentration of Cd could be due to excessive additives of mineral supplements in animal feeds in China, such as phosphate, zinc sulfate and Zn oxide, which contain high concentrations of Cd (Nong 2002, Zhong andJiang 2005).…”

Animal manure may be a primary source of cadmium (Cd) to Chinese farmlands because abnormally high values of Cd were observed in various manures. In this study, we evaluated the potential risk of Cd in soil-plant (maize and soybean) system as a result of the long-term (10 years) application of pig manure (PM). During 10 years, the loading rate of Cd through PM application ranged from 26.33-131.50 g/ha/year, while the crops removal rate of Cd was relatively small in comparison to the quantity of Cd supplied by PM application (1.03-4.36 g/ha/year). The PM application significantly increased total Cd concentration in soil. Although the Cd levels did not exceed the Chinese soil quality criteria (1.0 mg/kg dry matter (DM)), it would only take less than two years to reach this limit at high PM application rate. The same trend was also observed for the Cd concentration in maize and soybean. More seriously, Cd concentration in grain of soybean was higher than the threshold values for animal and human ingestion (0.2 mg/kg DM). Based on a mass balance calculation, we found that atmospheric deposition was also an important source of Cd in the experimental area (10.27 g/ha/year). Moreover, the application of PM enhanced the leaching loss of Cd, but they were still fairly small (0.34-0.73 g/ha/year).

“…The study was designed considering that (1) the EU limit of Cd in feed is 5 mg/kg (EC, 2005), (2) in some cases levels of Cd in feed can exceed maximum permitted limits (Li et al, 2010a), (3) the addition of elevated levels of essential elements may ameliorate the negative effects of toxic metal contamination (Nolan and Brown, 2000;Jemai et al, 2007;Jihen et al, 2008) and (4) the maximum allowed Se inclusion level in the United States is 0.3 mg/kg (Payne et al, 2005).…”

“…The maximum limit for Cd in water is 5 mg/kg (EC, 1998). International green trade barriers for agricultural products and domestic feed safety issues, combined with public awareness on the impact of Cd pollution, led to a considerable worldwide effort to reduce Cd discharge (Li et al, 2010a). Currently, Cd occurrence in food is a major issue for public health, and the panel on contaminants in the food chain of the European Food Safety Authority (EFSA) issued a statement maintaining the tolerable weekly intake at 2.5 mg per kg of BW (EFSA, 2011).…”

“…The use of mineral -E-mail: ezoidis@aua.gr premixes with high residues of Cd and application of animal manure, containing high Cd levels, as an organic fertilizer may be two routes of animal exposure (Cang et al, 2004;Liu et al, 2005). A study conducted in 14 Chinese provinces revealed that the highest Cd concentrations measured in those areas were 27.60, 31.00 and 21.92 mg/kg in pig, dairy cattle and chicken feed, respectively (Li et al, 2010a).…”

This work was part of a project designed to assess whether organic selenium (Se) can protect against the toxic effects of cadmium (Cd). A total of 300 1-day-old, as hatched, broilers were randomly distributed in four dietary treatments with five replicate pens per treatment. In T1 treatment, broilers were fed a diet with 0.3 mg/kg added Se, as Se-yeast, without added Cd; in T2, broilers were fed a diet with 0.3 mg/kg Se and 10 mg/kg Cd; in T3, broilers were fed a diet with 0.3 mg/kg Se and 100 mg/kg of Cd; and in T4 treatment broilers were fed a diet with 3 mg/kg Se and 100 mg/kg Cd. The Cd was added to diets T2, T3 and T4 as CdCl 2 . On the 4th and 6th week, two broilers per replicate pen were killed in order to obtain whole blood, liver, kidney and breast samples. Body mass, feed conversion ratio and mortality were assessed and haematological analyses were performed. Se and Cd levels in tissues were analysed by inductively coupled plasma mass spectrometry. Broilers supplemented with 0.3 mg/kg Se can tolerate low levels of Cd added to the diets, as there were no significant negative effects on the examined performance parameters, whereas addition of excess Cd led to an impairment of broilers' performance. Mortality of broilers did not differ between the four dietary treatments at any interval point or the whole period. The examined haematological parameters such as haematocrit, total blood protein concentration, and leukocytes types ranged within physiological values, revealing no negative health effects after simultaneous Cd and Se addition. The present study indicated that Se can help against the negative effects of Cd, but cannot counteract all of its negative effects.

“…There are many mathematical models to solve the problems caused by hazardous materials (hazamat). Discrete location-routing model is typical, and quite a few models solving methods have been developed [1][2][3][4][5][6][7][8][9]. Erkut [1] had an in-depth discussion on the hazamat transportation problems, especially on the risk assessment to the path, and created several models.…”
