Abstract Clean air is important for human health and well-being, air pollution has increased in many parts
worldwide and thus posing a significant threat people’s health. In Kenya, the traffic police officers who constantly
un covered stand on road junctions continuously expose themselves to motor vehicle emissions, greatly risking their
health. This study collected qualitative data and quantitative data analysed police person’s perceptions of the health
impact of motor vehicle emissions on traffic police in Nairobi, Kenya. The respondents were sampled from among
the traffic police officers who normally control traffic in Nairobi CBD. Pretested questionnaires were used to collect
data. The study showed that police officers were aware of the effects that the motor vehicle air pollution could have
on their health. About 98.1% of respondents indicated that they are affected by motor vehicle pollution. On average,
about 30% of the police officers are off duty due to sickness while 82.2% had been greatly affected by exposure to
motor vehicle pollution. 58.9% new cases of the health effects related to motor vehicle emission constant though
majority did not take any measures. They obtained this knowledge and experience from their colleagues suffering
from respiratory diseases; reporting frequent occurrence of health problems thought to arise acquaintance to motor
vehicle emissions. The study accomplishes that there is an association between the amounts spent manning traffic
and contact to high levels of pollution. The traffic officers have associated illnesses such as respiratory problems,
asthma, cancer and other diseases that are pollution related to the high emissions of motor vehicle pollution in the
Central business district.

1. Introduction
Dominant part of the present vehicles utilize inward
combustion engines that consume gas or other petroleum
products; and disregard to supplant worn or deteriorated
segments by Motorists which result in poor engine
performance, higher fuel utilization, motor harm and
excess emissions [1,2]. During combustion, various
vaporous materials and pollutions are produced. These
ignition side-effects are discharged into the environment
as fumes gasses. Among the gasses stand nitrogen oxides,
carbon monoxide, sulfur dioxide, lead and particulate
matters that contaminate the atmosphere. It has been
affirmed that, in creating nations of the world, vehicular
development has been to a great extent unchecked by
natural managing bodies making large amounts of
contamination [3]. One of the main worries of air
contamination is the unfavorable wellbeing it has on
wellbeing. Confirmation focuses to air contamination that
shoots from transport as an essential supporter of ill health.
In Kenya, every person is eligible to a clean and healthy
atmosphere and he or she is indebted to enhance it. The
entitlement to a clean and healthy environment includes
the access by persons in Kenya to the various public
elements or segments of the environment for recreational,
educational, health, spiritual and cultural purposes [4].
World Health Organization battles that perfect air is a
fundamental necessity for human wellbeing and prosperity
despite the fact that air contamination keeps on representing a
noteworthy risk to wellbeing around the world. As
indicated by their appraisal of the weight of ailment
because of air contamination, more than two million
unexpected losses happening every year can be ascribed to
the impacts of urban open air and indoor air contamination
caused by the consuming of petroleum products [5]. The
greater part of these ailment troubles, specifically respiratory
complexities, are borne by the populaces of creating
nations Kenya included [5], currently urban air pollution
is increasing.
The traffic police department’ mandate ensure that
drivers on the road comply with the traffic Act and related
subsidiary legislations. A majority of the traffic police
staff have to spend much of their time on the roads while
on duty. In these circumstances therefore, they are
exposed to particulate matter and exhaust gases emitted by
the vehicles on the road. This situation is worsened during
peak hours when the traffic is heavy and more pollutants
are released into the ambient air. This may affect their
