TLDR
The South-East Queensland (SEQ) region is one of the fastest growing areas in Australia as mentioned in this paper and this rapid growth and the accompanying increase in vehicle kilometres travelled has brought demand for management methods to deal with air pollution.Abstract:

A survey on the effects of vehicle emissions on human health in Nigeria.
TL;DR: The effects of vehicular emissions on human health, vegetations, and environments were investigated in three locations of Lagos, Nigeria while a fourth location was used as a control since it has low levels of pollution.

Seasonal variability of carbon monoxide (CO) in the ambient environment of Imo State, Nigeria
TL;DR: In this paper, the air quality of four areas in Imo State with a total of twenty two locations were monitored for a period six months with respect to CO level using Gasman air monitor (Crowcon Instruments Ltd, England), and the results obtained showed significant variation of the air pollutant in the morning, afternoon and evening including within the twenty four weeks, and between dry and wet seasons, and the mean values of CO in the dry season are in the order Egbema > Okigwe > Owerri > Orlu, while the order for the mean CO

Uncertainties and Errors in Predicting Vehicle Exhaust Emissions using Traffic Flow Models
TL;DR: In this paper, the authors developed a data-driven methodological framework to probabilistic average speed-based emission predictions using two widely deployed macroscopic traffic flow models, the Cell Transmission Model (CTM) and METANET, a discretised second-order Payne type model.
Assessment of vehicular emissions and health impacts in Jos, Plateau State
Johnson Alfred,Amos Hyeladi +1 more
TL;DR: In this article, the authors used the pearson product moment coefficient correlation statistical technique to test the hopothesis that there is a significant relationship between vehicle increase, high exposure to vehicle emissions and increase in air pollution related diseases.

Economic valuation of air quality in Kenya
TL;DR: In this paper, the authors employed stated preferences to estimate the economic value of air quality in Kenya through motorized emission reductions in the city of Nairobi, and employed the discrete choice experiments (DCEs) to analyze the implicit prices that motor vehicle owners would be willing to pay towards specific motorised emission reduction attributes.

Engines and nanoparticles: a review
TL;DR: In this article, a new HEI study showed that some low-emission diesel engines emit much higher concentrations of nanoparticles than older designs and other low-EMission designs, which has raised questions about whether nanoparticle (number based) emission standards should be imposed.
Journal ArticleDOI
Is Daily Mortality Associated Specifically with Fine Particles
TL;DR: The data suggest that increased daily mortality is specifically associated with particle mass constituents found in the aerodynamic diameter size range under 2.5 urn, that is, with combustion-related particles.

Submicrometer and Supermicrometer Particulate Emission from Spark Ignition Vehicles
TL;DR: In this article, the authors used the Scanning Mobility Particle Sizer (SMPS) and APS (APS) to determine the particle number concentration and size distribution for 11 gasoline powered and 2 liquefied petroleum (LPG) powered passenger vehicles.

TL;DR: One hundred and three in-use vehicles, identified as high hydrocarbon and/or carbon monoxide emitters by remote sensing and roadside visual, underhood checks during a 1995 South Coast Air Quality Management District program, were tested on the IM240 cycle using a transportable dynamometer as mentioned in this paper.
