Rapid urbanization, the corresponding increase in vehicle ownership, and the continued use of solid fuels as an energy source have resulted in the deterioration of air quality in Kenya. Despite this, there is no publicly available official source of data on air pollution in the country. This article provides an overview of published studies that report the concentrations of widespread ambient pollutants, outline major themes, and identify data gaps. This review reveals that since the 1980’s particulate matter (PM) concentrations in some Nairobi locations, such as the industrial area, have been at dangerously high levels. Almost all of the studies included show that PM concentrations in Nairobi violate the World Health Organization (WHO) guidelines. Moreover, black carbon (BC) concentrations in Nairobi are among the highest in the world, indicating the need for cleaner vehicles in the city. There has been much less work done measuring the levels of gaseous pollutant concentrations in Kenya. Based on these findings, policies to reduce air pollution in Kenya and monitoring strategies to fill in the existing gaps are presented.

肯尼亚的空气污染：回顾

快速城市化、汽车保有量相应增加以及固体燃料作为能源的持续使用导致肯尼亚空气质量恶化。尽管如此，该国还没有公开的官方空气污染数据来源。本文概述了已发表的研究报告，这些研究报告了广泛存在的环境污染物的浓度、概述了主要主题并确定了数据差距。该审查表明，自 1980 年代以来，内罗毕某些地区（例如工业区）的颗粒物 (PM) 浓度一直处于危险的高水平。几乎所有纳入的研究都表明，内罗毕的 PM 浓度违反了世界卫生组织（WHO）的指导方针。此外，内罗毕的黑碳 (BC) 浓度是世界上最高的，表明城市需要更清洁的车辆。在肯尼亚，测量气态污染物浓度水平的工作要少得多。根据这些调查结果，提出了减少肯尼亚空气污染的政策以及填补现有差距的监测策略。
