Landfilling is one of the indispensable parts of solid waste management in various countries. Solid waste disposed of in landfill sites provides nutrients for the proliferation of pathogenic microbes which are aerosolized into the atmosphere due to the local meteorology and various waste disposal activities. Bioaerosols released from landfill sites can create health issues for employees and adjoining public. The present study offers an overview of the microbial diversity reported in the air samples collected from various landfill sites worldwide. This paper also discusses other aspects, including effect of meteorological conditions on the bioaerosol concentrations, sampling techniques, bioaerosol exposure and potential health impacts. Analysis of literature concluded that landfill air is dominated by microbial dust or various pathogenic microbes like Enterobacteriaceae, Staphylococcus aureus, Clostridium perfringens, Acinetobacter calcoaceticus and Aspergillus fumigatus. The bioaerosols present in the landfill environment are of respirable sizes and can penetrate deep into lower respiratory systems and trigger respiratory symptoms and chronic pulmonary diseases. Most studies reported higher bioaerosol concentrations in spring and summer as higher temperature and relative humidity provide a favourable environment for survival and multiplication of microbes. Landfill workers involved in solid waste disposal activities are at the highest risk of exposure to these bioaerosols due to their proximity to solid waste and as they practise minimum personal safety and hygiene measures during working hours. Workers are recommended to use personal protective equipment and practise hygiene to reduce the impact of occupational exposure to bioaerosols.

填埋是各国固体废物管理不可缺少的组成部分之一。在垃圾填埋场处置的固体废物为病原微生物的增殖提供了养分，这些病原微生物由于当地气象和各种废物处理活动而气溶胶化到大气中。从垃圾填埋场释放的生物气溶胶会给员工和邻近的公众带来健康问题。本研究概述了从全球各个垃圾填埋场收集的空气样本中报告的微生物多样性。本文还讨论了其他方面，包括气象条件对生物气溶胶浓度的影响、采样技术、生物气溶胶暴露和潜在的健康影响。肠杆菌科,金黄色葡萄球菌,产气荚膜梭菌,醋酸钙不动杆菌和烟曲霉. 垃圾填埋场环境中存在的生物气溶胶具有可吸入的大小，可以深入下呼吸系统并引发呼吸道症状和慢性肺部疾病。大多数研究报告了春季和夏季较高的生物气溶胶浓度，因为较高的温度和相对湿度为微生物的生存和繁殖提供了有利的环境。参与固体废物处理活动的垃圾填埋场工人接触这些生物气溶胶的风险最高，因为他们靠近固体废物，而且他们在工作时间采取最低限度的个人安全和卫生措施。建议工人使用个人防护设备并保持卫生，以减少职业接触生物气溶胶的影响。
