摘要:
摘要 采用“非浸没培养皿法”(nonflooded petri dish method)培养, 对李坑垃圾填埋场垃圾渗滤液淋灌的土壤中的原生动物群落进行了分析.实验发现4属4种纤毛虫:膨胀肾形虫(Colpoda inflata)、有肋薄咽虫(Leptopharynx costatus)、莫式拟肾形虫(Paracolpoda maupasi)、恼斜板虫(Plagiocampa difficils).随淋灌中垃圾渗滤液浓度的上升, 出现的纤毛虫种类呈递减趋势, 从定量实验的结果来看, 即使是较低浓度的垃圾渗滤液, 也对土壤原生动物群落造成了较大的伤害.25%浓度 的垃圾渗滤液淋灌的土样中, 原生动物数量仅为CK组的30%;超过50% 浓度的渗滤液稀释液淋灌土样,则仅为CK组的10%左右.数据表明污染物本身并没有被降解,而是全部(或至少大部分)转移到了受渗滤液影响的土壤中, 从而导致土壤中的原生动物群落的结构无论是从数量上还是从种类上均遭到相当大的破坏. 表4 参15
Abstract:
Abstract The protozoan communities in soil samples irrigated with the leachate from Likeng landfill in Guangzhou were studied using nonflooded petri dish method. Four species of ciliates belong to four different genera: Colpoda inflata, Leptopharynx costatus, Paracolpoda maupasi and Plagiocampa difficils. The species number decreased as increasing of landfill leachate concentration. It was showed that landfill leachate, even in low concentration, could largely harm soil protozoan. Only 30% abundance of control remained in the sample irrigated with 25% landfill leachate solution. Only 10% number of control remained in the sample irrigated with landfill leachate solution that was higher than 50%. The pollutants were not degraded, but (at least most of them) transferred into the soil that was polluted by landfill leachate, which demolished the structure of soil protozoan communities.
