“…The contents of each cartridge were transferred to a 2-mL vial and added to 1000 μL of dichloromethane at − 20 °C. The flasks were capped with septum caps, placed in an ultrasonic bath for 20 min, and then allowed to rest for 1 h (Correa et al, 2012 ; Corrêa and Arbilla, 2007 , 2006 ; Daemme, 2016a ; Daemme, 2016b ; Garcia et al, 2013 ; Macedo et al, 2017 ; Martins et al, 2016 , 2007 ).…”

“…The temperatures of the ion trap, manifold, and transfer line were 150 °C, 40 °C, and 180 °C, respectively. The MS detector monitored ions from 72 to 79, 89 to 93, 101 to 107, and 119 to 121 (m/z) (Correa et al, 2012 ; Corrêa and Arbilla, 2007 , 2006 ; Daemme, 2016a ; Daemme, 2016b ; Garcia et al, 2013 ; Macedo et al, 2017 ; Martins et al, 2016 , 2007 ). The calibration was performed with a standard BTEX solution (Supelco EPA TO-1 Mix 1A) by external standardisation with concentrations of 0.10, 0.20, 0.50, 1.00, 2.00, and 4.00 ng mL −1 , as an acceptance criterion of the analytical curve determination coefficients higher than 0.99.…”

This study assessed the emissions of gaseous pollutants and particle size distributed water-soluble organics (WSO) from a diesel vehicle fuelled with ultralow sulphur diesel (B0) and 10 (B10), 20 (B20), and 30% (B30) biodiesel blends in a chassis dynamometer tested under transient mode. Particulate emission sampling was carried out in an ultraviolet (UV) test chamber using a 10-stage impactor. Samples were grouped into three size fractions and analysed by gas chromatography-mass spectrometry. Increasing the biofuel ratio up to 30% in the fuel reduced WSO emissions by 20.9% in comparison with conventional diesel. Organic acids accounted for 82–89% of WSO in all tested fuels. Dicarboxylic acids were the most abundant compound class, followed by hydroxy, aromatic, and linear alkanoic acids. Correlations between compounds demonstrated that adding biodiesel to diesel fuel reduces the emissions of nitrogen oxides (NOx), benzene, toluene, ethylbenzene and xylenes (BTEX), methane (CH4), total and nonmethane hydrocarbons (THC and NMHC), and dicarboxylic and hydroxy acids, but increases emissions of carbon dioxide (CO2) and alkanoic and aromatic acids. Emissions of dicarboxylic and hydroxy acids were strongly correlated with the biodiesel content. WSO emissions of coarse and fine (1.0–10 μm) particles decreased with the increasing biofuel content in fuel blend. The total share of ultrafine (0.18–1.0 μm) and nanoparticles (< 0.18 μm) increased in WSOs emissions from B20 and B30 blends, when compared with petrodiesel. The biodiesel content also affected the chemical profile of WSO size fractions.

Intensive urbanization processes, an increase in the number of urban population and transport have led to an increase in the technogenic load on the environment, in particular on the atmospheric air. Among a significant number of sources of environmental pollution, roads and vehicles pose a significant threat. Motor vehicles cause irreparable harm to human health and the environment. Regular assessment of the quality of atmospheric air in residential areas of cities with heavy traffic to establish the level of potential risk to public health is an urgent task. The study purpose is the social consequences of transport emissions; determination of the anthropogenic load on the air and of the indicator of public health risk from the vehicle exhaust impact. The study was carried out on the example of the residential and the most loaded transport area of Poltava (Ukraine). The study demonstrates that the overwhelming majority of the urban population lives in areas where health risk indicators exceed permissible norms. Since the elderly, children and students are most often present on the street and near houses, they are at the greatest risk. The same applies to vehicle drivers who are often idle in "traffic jams". In turn, such high levels of air pollution pose even greater risks to public health, in particular to the development of respiratory diseases. In the study of the peculiarities of Ukrainian legislation in this area, it was established that the mechanism for collecting information about the quality of the environment, however, there is no requirement to inform the population about it.

“…The use of motorcycles as a form of transportation increases daily in developing countries like Nigeria. Motorcycles are preferred to small cars in such countries because of low maintenance, low fuel consumption, ease of parking and affordability, which outweighs the disadvantages such as bad traffic accidents, high cost of insurance and interfering rain [8]. Tricycle in Nigeria today is majorly used for commercial purposes because it is affordable and quick means of transportation.…”

The emissions of carbon monoxide, carbon dioxide, and hydrocarbon from four stroke-powered motorcars and two stroke-powered motorcycles and tricycles in Southwest Nigeria were examined using an automotive 4-gas analyer. Results show that tricycles produced more hydrocarbon and carbon monoxide emissions than motorcycles, while motorcycles emitted more of these pollutants than the gasoline fueled motor cars. (The gasoline fueled motorcars produced lowest hydrocarbon and carbon monoxide while the tricycles produced the highest hydrocarbon and carbon monoxide emissions). On the contrary, motor cars had the highest mean value of carbon dioxide followed by the motorcycles, while tricycles had the least. This could be attributed to the presence of the catalytic converters in some of the motor cars oxidizing carbon monoxide to carbon dioxide. The mean values of hydrocarbon, carbon monoxide and carbon dioxide emissions from motorcars are 630ppm, 10200ppm and 59900ppm. This is much higher than the NESREA (National Environmental standards and Regulations Enforcement Agency) standards as well as Euro II and Euro III (European standards) for vehicular emission. The mean values for hydrocarbon, carbon monoxide and carbon dioxide emissions from motorcycles and tricycles are (2150ppm, 21530ppm and 31200ppm) and (2820ppm, 24880ppm and 38710ppm) respectively. These results do not comply with Nigeria and European emission standards for hydrocarbon, and carbon monoxide. Tricycles and motorcycles account for higher concentrations of hydrocarbon and carbon monoxide pollutants from mobile sources, while they emit carbon dioxide minimally.
