Sources and Accumulation Risk of Heavy Metal in Major Animal manure

引用

Animal Husbandry and Feed Science 2016年第6期8卷 318-322,326页

作者： Shi Yanping Huang Jinfa Ni Xiongwei Xie Jianping Ren Jiajia Jiaxing Workstation of Soil and Fertilizer Jiaxing 314050 China

Feed and corresponding manure samples were collected from 27 scale pig farms and 7 scale chicken farms in Jiaxing City, Zhejiang Province, and their heavy metal contents were analyzed. The weighted average values of Cr, Cu, Zn, Pb and As in pig feed were 4.6, 123.4,370.7, 0. 69 and 6.9 mg/kg, respectively. However, referred to Safe Use Specification of Feed Additives and MOA Announcement No. 1224, the exceeding standards rates of Cr, Cu, Zn, Pb and As in pig feed were 5.36%, 62.5%, 19.64%, 3.57% and 37.5%, respectively. The sequences of heavy metal content in pig feed successively were piglet 〉 growing pig 〉 big pig 〉 sow, but the exceeding standard rates of heavy metal in feed were big pig 〉 sow 〉 growing pig 〉 piglet, and the exceeding standard rate of big pig feed was more than 95%. The exceeding standard rates of Cu, Zn and As in chicken feed were 46.7%, 11.1% and 33.3% respectively. Based on Organic Fertilizer （ NY525 -2012 ） and Sludge Agricultural Pollution Control Standard （ GIM284-84）, Cu, Zn and As in pig manure and chicken manure exceeded the standard; the exceeding standard rates of pig manure were 71.9%, 78.9% and 42.1%, while that of chicken manure were 12.5%, 25.0% and 44.4%, respectively. The exceeding standard rates of Cu and Zn in piglet manure reached 100%. There were very significant positive correlations in Cu, Zn and As between pig feed and corresponding manure, or Hg, Cu and As between chicken feed and corresponding manure, and the correlation eoeffi 2 cients r were greater than 0.8. Besides, the correlation coefflclent r of Pb between pig feed and corresponding manure was above 0.6. Continuous and high intensity of livestock manure application significantly promoted the accumulation of heavy metal in farmland soil, but the effects on heavy metal accumulation in rice was not significant.
