“…However, the high concentration of HMs in PBR is also of great concern. Excessive HM concentrations have been widely reported in animal manures (Cang et al 2004;Li and Chen 2005;Li et al 2007;Kuligowski et al 2008). In this study, high concentrations of As, Cd, Cu and Zn were also found in pig manures (Table 1).…”

“…To shorten the duration of breeding and to control diseases, HMs are usually given to livestock and poultry as feed additives (Nicholson et al 1999;Dach and Starmans 2005;Li et al 2007). HMs ingested by animals are mostly excreted with feces and urine, such as 92-96% of zinc (Zn), and 72-80% of copper (Cu).…”

“…Cu and Zn are the most widely used HMs for pig diets as feed additives. Accordingly, high concentrations of Cu and Zn in pig manure and agricultural soils have been reported in areas with intensive pig production (Cang et al 2004;Mishima et al 2005;Ogiyama et al 2005Ogiyama et al , 2006Li et al 2007;Zieliń ska et al 2009). For example, Cu concentrations were reported to be 6.86-395.19 mg kg À1 in pig feed sampled from Beijing and Fuxin cities (Li et al 2007), and 1726.3 mg kg À1 in pig manure sampled from Jiangsu province (Cang et al 2004); also similarly high concentrations of Cu and Zn in pig feed and manure have been reported in some other countries (Nicholson et al 1999).…”

However, with the popularization of biogas projects, less and less animal manure is used directly as a fertilizer for crops and vegetables, while PBR is replacing animal manure used as fertilizer.…”

Pig-biogas residue is widely used as organic fertilizer for rice (Oryza sativa L.) in China. To evaluate the risk of heavy metal contamination in paddy soil and rice grains caused by long-term pig-biogas residue fertilization, this study was conducted in paddy fields which had been fertilized continuously with pig-biogas residue for 8 years. We found that pig-biogas residues contained high concentrations of arsenic (As), cadmium (Cd), copper (Cu) and zinc (Zn). As a result, the concentrations of these four metals in paddy soils and rice grains sampled from biogas residue fertilized fields were significantly higher than those from control fields. In addition, in biogas residue fertilized fields, the concentrations of these four metals rapidly increased in the tillage layer compared with those in deep soil layers, and biological availability was significantly higher than in control fields. Moreover, we found that the accumulation of these four metals in paddy soils and rice grains increased in the second year compared with the first year. To reduce heavy metal accumulation in rice grains, we screened for rice genotype among 20 local rice genotypes. We found obvious genotypic differences in grains' accumulation of heavy metals, and identified some rice genotypes which had low accumulation of multiple heavy metals. These low-accumulating genotypes predicate the possibility to reduce heavy metal accumulation in rice grains grown in pig-biogas residue fertilized fields.

“…Until now, China has had no standards for the reasonable use of Cu and Zn 495 additives in concentrated animal production. As a result of this, Cu and Zn additives are commonly oversupplied in animal feeding stuffs in China (Li et al 2007, Xiong et al 2010). Hence, it was important to establish the regulations of the use of additives permitted in pig feed for reducing the Zn and Cu contents in pig manure.…”

Fertilization of crops with pig manure is a common practice throughout the world. Nevertheless, due to the relatively high copper (Cu) and zinc (Zn) contents in pig manure, continuous application of pig manure could have negative effects on soil and plant. The study aimed at the impacts of long-term applying different pig manure rates (equivalently 0, 100, 250 and 500 kg total N/ha/year from 2002 to 2008 and 0, 10, 25 and 50 t fresh weight/ha/year from 2009 to 2011, respectively) on Cu and Zn accumulation in soil and plant. During the 10 years of the experiment, a total of 2.04 to 10.20 kg/ha/year for Cu, 3.15 to 15.73 kg/ha/year for Zn were applied to the soil. Results from this study showed that long-term pig manure application resulted in serious accumulation of Cu and Zn in soil, total Cu and Zn concentrations increased by 204% and 107% at high application rates, respectively. Although topsoil Cu and Zn concentrations were below concentrations considered phytotoxic to crops, according to current Chinese legislation, it would take only less time than 16 and 27 years of high application rates to reach the allowable limits. Our result also suggested that Cu and Zn leaching occurred in the tested soil. The Cu and Zn concentrations in stalks and grains were not affected by the application of pig manure, and these values were lower than the threshold values for animal and human ingestion.
