“…This reduced sulfur content diesel fuel is known as ultra-low sulfur diesel (ULSD, S<15 ppm) fuel [13]. Thus, lower sulfur diesel fuels reduce emissions of sulfur compounds (a cause of acid rain) and a major reason for reducing sulfur levels is to avoid poisoning of catalysts responsible for reducing these exhaust emissions species [14].…”

The jojoba plant (Simmondsia chinensis L.) produces seeds that contain around 50 to 60 wt.% of inedible long-chain wax esters that are suitable as a potential feedstock for biodiesel (BD) production. Jojoba oil methyl esters (JME) were prepared from acid-catalyzed pretreated jojoba oil in order to evaluate important fuel properties of jojoba-based BD, including kinematic viscosity, cloud point (CP), pour point (PP), cold filter plugging point (CFPP), acid value (AV), oxidative stability, and lubricity. A comparison was made with soybean oil methyl esters (SME) and relevant BD fuel standards such as ASTM D6751 and EN 14214. JME was characterized using Fourier transform infrared spectroscopy and 1 H and 13 C nuclear magnetic resonance. The CP, PP, and CFPP of JME were −13°C, −16°C, and −14°C, respectively, which were superior to SME. The kinematic viscosity (40°C) of JME was 6.67 mm 2 /s, which was higher than observed for SME. Blends (B5 and B20) of JME in ultra-low sulfur diesel fuel (ULSD) were also evaluated for the aforementioned fuel properties and compared to an analogous set of blends of SME in ULSD and relevant petro diesel fuel standards such as ASTM D975 and D7467. JME blends in ULSD displayed improved low-temperature properties in comparison to neat ULSD and blends of SME in ULSD. In summary, jojoba oil has potential as an alternative, nonfood feedstock for BD production.

“…3(C)). S is attributed to the emission from diesel and heavy fuel oil combustion (Tan et al, 2009) whereas Br is attributed to both biomass burning (Cicerone, 1994) and exhaust emissions (Maenhaut and Akilimali, 1987). In Kenya, the diesel fuel for both vehicular and industrial consumption contains 5000 parts per million of sulphur (UNEP, 2014).…”

Information from elemental and mass composition of size-fractionated airborne particle matter (PM) provides insightful knowledge about their impact on human health, meteorology and climate. To attain insight into the nature of sizefractionated PM from a typical African city, samples were collected from an urban background site in Nairobi, Kenya, during the months of August and September in 2007. PM samples ranging in size from 0.06 to 16 µm aerodynamic diameter were collected on pre-weighed polycarbonate filters with 0.4 µm pore size using a nine-stage cascade impactor. Particles less than 0.06 µm were collected on a backup filter. A total of 170 samples were collected and analysed for trace elements using the Proton Induced X-Ray Emission (PIXE) technique. The analysis showed that Si, Fe and S dominated in all size ranges and displayed unimodal mass-size distribution whereas K, Cu, Zn and Pb, depicted bimodal mass-size distribution highlighting the multiplicity of their sources. To estimate human exposure to PM, deposition fractions of both the coarse and fine PM in the human respiratory system were calculated. The deposited concentration was found to be highest in the head airways region compared to the tracheobronchial and pulmonary regions.
