不同形态微塑料对粪源重金属在土壤中迁移的影响
Effect of Different Forms of Microplastic Fibers on Migration of Heavy Metals from Manure in Soil
摘要
Abstract
In order to study the effects of different forms of Microplastics(MP)on the migration of heavy metals from livestock and poultry manure in soil,different forms of Polypropylene(PP)were se-lected as raw materials for Microplastics,and layer hen's manure was taken as the manure source model.Two kinds of micro-plastic fragments with different sizes and two kinds of micro-plastic fibers with differ-ent diameters were added into the experimental soil with the proportion of 1％and 10％respectively.The results showed that different forms of microplastics had different effects on the migration of different heav-y metals.The microplastics in soil inhibited the migration of Cu,and the smaller the form,the stronger the inhibition.The optimal absorption effect of Cu was observed in small fragmented plastics.Additional-ly,the microplastic in soil accelerated the migration of Zn and Cd,but exerted little impact on the migration of Pb.The soil electrical conductivity was slowed down under the influence of fibrous microplastics.关键词
