“…Many recent studies have shown that, people are more at risk of occupational exposure to ambient air pollutants than other means, 2 3 6 18–21 and evidences have also shown that urban city transit operation (eg, commercial motorcycling and taxi driving) are examples of such occupations that expose workers to unusual large amount of outdoor ambient air pollutants. 22 The work entails conveying passengers to and from their different destinations within and even to the outskirts of the city for commercial gains.…”

ObjectivesTo assess the respiratory health effect of city ambient air pollutants on transit and non-transit workers and compare such effects by transportation mode, occupational exposure and sociodemographic characteristics of participants.DesignCross-sectional, randomised survey.SettingA two primary healthcare centre survey in 2009/2010 in Uyo metropolis, South-South Nigeria.ParticipantsOf the 245 male participants recruited, 168 (50 taxi drivers, 60 motorcyclists and 58 civil servants) met the inclusion criteria. These include age 18–35 years, a male transit worker or civil servant who had worked within Uyo metropolis for at least a year prior to the study, and had no history of respiratory disorders/impairment or any other debilitating illness.Main outcome measureThe adjusted ORs for respiratory function impairment (force vital capacity (FVC) and/or FEV1<80% predicted or FEV1/FVC<70% predicted) using Global Initiative for Chronic Obstructive Lung Diseases (GOLD) and National Institute for Health and Clinical Excellence (NICE) criteria were calculated. In order to investigate specific occupation-dependent respiratory function impairment, a comparison was made between the ORs for respiratory impairment in the three occupations. Adjustments were made for some demographic variables such as age, BMI, area of residence, etc.ResultsExposure to ambient air pollution by occupation and transportation mode was independently associated with respiratory functions impairment and incident respiratory symptoms among participants. Motorcyclists had the highest effect, with adjusted OR 3.10, 95% CI 0.402 to 16.207 for FVC<80% predicted and OR 1.71, 95% CI 0.61 to 4.76 for FEV1/FVC<70% predicted using GOLD and NICE criteria. In addition, uneducated, currently smoking transit workers who had worked for more than 1 year, with three trips per day and more than 1 h transit time per trip were significantly associated with higher odds for respiratory function impairment at p<0.001, respectively.ConclusionsFindings of this study lend weights to the existing literature on the adverse respiratory health effect of ambient air pollution on city transit workers globally. The role of other confounders acting synergistically to cause a more deleterious effect is obvious. In all, the effect depends on the mode and duration of exposure.

“…Hair has been increasingly used as a monitor for many elements and has been proposed for assessing environmental exposure, nutritional status, and for diagnosis of disease [1][2][3][4][5]. Hair has many advantages for assessment over the more traditional kinds of medical objects such as blood and urine because of ease of collection, transport, and storage.…”

The effect of age and gender on minor and trace element contents in the scalp hair of 80 relatively healthy 15- to 55-year-old women and men was investigated. Contents or upper limit of contents of 37 chemical elements in the scalp hair were determined by instrumental neutron activation analysis. Mean values (M +/- SEpsilonMu) for the mass fraction of Ag, Au, Ba, Br, Ca, Ce, Cl, Co, Cr, Eu, Fe, Hf, Hg, I, K, La, Lu, Mg, Mn, Na, Rb, Sb, Sc, Se, Sm, Sr, Th, and Zn (milligrams per kilogram of dry hair) were 0.191 +/- 0.018, 0.0102 +/- 0.0014, 6.33 +/- 0.68, 3.59 +/- 0.26, 1320 +/- 110, 0.369 +/- 0.055, 1245 +/- 133, 0.0707 +/- 0.0054, 2.78 +/- 0.22, 0.0082 +/- 0.0021, 88.2 +/- 6.7, 0.040 +/- 0.012, 0.145 +/- 0.009, 6.93 +/- 1.05, 146 +/- 14, 0.238 +/- 0.025, 0.0030 +/- 0.0007, 163 +/- 17, 2.29 +/- 0.30, 344 +/- 31, 0.65 +/- 0.10, 0.062 +/- 0.005, 0.0100 +/- 0.0012, 0.248 +/- 0.008, 0.0090 +/- 0.0010, 45.7 +/- 3.5, 0.0168 +/- 0.0019, and 154 +/- 3, respectively.

“…Ozone is also a principal pollutant in many urban areas. In most West African cities such as Nigeria, as well as other major cities of the advanced world, outdoor ambient air pollution has been identified as a major threat to human health [3,4,5,6,7,8,9]. Poor ambient air quality is capable of negatively altering the average life span of individuals, communities or even nations that are constantly exposed to it.…”

Ambient air pollution is a global concern. It accounts for an estimated 4.2 million deaths yearly as a result of its ability to cause stroke, lung cancer, heart disease and chronic respiratory diseases. It has also been estimated that about 91 percent of the world's population lives in places, mostly urban centres, where air quality levels exceed World Health Organization (WHO) limits. Fortunately, efforts are regularly made in most developed countries to monitor and reduce the level of air pollution and ameliorate its negative consequences. Unfortunately, the case is not the same in most developing countries of which Nigeria is a member, as air pollution status is rarely monitored religiously. This study geospatially assessed ambient air quality footprints vis-à -vis urban land uses in Calabar Metropolis, Nigeria. Data on emission level of CO, NO 2 , SO 2 , H 2 S, and SPM 2.5 were collected for 6 months in both dry and wet seasons in the year 2020, using Crowcon Gasman, while point coordinates were collected using Garmin GPSMap 60CSx device. Geographic Information Systems (GIS) infrastructure was deployed to generate the ambient air quality maps for the metropolis. Descriptive and parametric analytical techniques were also deployed, based on the objectives of the study. From findings, F-ratio is significant for both season and land use for all the tested parameters (F-ratio for season is F(1,3224)=574.516, at p<0.05, while for land use, F(3,3224)=429.946, at p<0.05). The interaction between seasons and land use (season * land use) for all the parameters is also significant. It was concluded that there is a significant variation in air quality (CO, NO 2, SO 2, H 2 S, and SPM 2.5 ) in Calabar Metropolis in relation to either land use types or seasons of the year. It was therefore recommended that there should be protection of residential land uses to avoid encroachment by incompatible uses that cause pollution.
