不同类型畜禽粪便Zn的形态分布及冻融作用对畜禽粪便Zn活性的影响
Form Distribution of Zn in Livestock and Poultry and Influence of Freezing and Thawing on Activity of Zn in Livestock and Poultry Mature
摘要
Abstract
With the development of poultry breeding and increasing of heavy metal such as Zn additive amount in feed,heavy metals in animal manures have become the considering resource of heavy metals in soils.The active of heavy metals in animal manures is related closely to its forms and moreover may be affected by freezing and thawing through changing the properties of animal manures.Therefore,there will be of the significance to study the form distribution of heavy metals in livestock and poultry manures under no freezing and thawing and effect of freezing and thawing on activity of Zn in livestock and poultry matures by the laboratory simulation for rightly assessing the pollution effect of Zn in livestock and poultry matures.The results showed that:the contents of Zn in the manure of chicken,pig and cow were 225.07mg· kg-1,334.00 mg· kg-1 and 214.19 mg· kg-1,respectively,the order of Zn contents in the manures were pig＞chicken＞cow; according the average concentrations of each fraction in the total contents of Zn in the manures,the form distribution of Zn in the livestock and poultry manures was residual》organic》Fe-Mn oxides＞carbonate or exchangeable under no freezing and thawing.the percentage of residual combined with organic was over 90％ and the percentage of carbonate combined with exchangeable was far lesser than 10％; the contents of both of carbonate and exchangeable increased significantly after freezing and thawing manures,it indicated that freezing and thawing improved the activity of Zn in livestock and poultry manures.关键词
