Summary: This article questions the fiscal advantage of diesel fuel in Portugal based on economic and environmental reasons. The study shows that diesel consumption in Portugal is insensitive to price changes and instead heavily dependent on economic growth due to its predominant use in commercial sectors. Therefore, higher taxes on diesel may not effectively moderate demand and could hinder firms' competitiveness. To protect the environment, alternative policy options such as environmental standards and incentives for electric mobility should be explored.

Summary: This study used a high-speed camera and a thermal camera to observe the evolution of fuel droplet diameter, flame structure, and maximum flame temperature over time. Traditional fuels (diesel and gasoline) and new generation fuels (triethyl borate and trimethyl borate) were investigated. It was found that diesel and gasoline fuel droplets have a large non-luminous region in the flame structure, unlike triethyl borate and trimethyl borate fuels. The time-dependent variation of the droplet diameter generally followed the D2-law. The flame formed by trimethyl borate had the highest temperature and the shortest burning time.

Summary: The study showed that particulates emitted from gasoline/diesel dual-fuel combustion were easier to oxidize and had higher volatile organic fraction compared to diesel particles. It was also found that particles at lower engine speed exhibited higher oxidation reactivity and volatile organic fraction. The nanostructure of dual-fuel soot contributed to its increased oxidative reactivity, with a more amorphous nature being a key factor.

Summary: The diesel-powered transportation sector is a major producer of environmental pollution in the form of diesel exhaust particles (DEP) which can affect the health and survival of pollinators. Researchers exposed Bombus terrestris to different concentrations of DEP and found that chronic oral exposure to high doses of DEP resulted in increased mortality. However, acute oral exposure showed no dose-dependent effects on survival or fat body content of the bees. These findings highlight the potential harmful effects of high levels of DEP on insect pollinators.

Summary: This study investigates the particulate emission and soot characterization of particles from a six-cylinder common-rail direct injection (CRDI), turbocharged diesel engine. The effects of different engine loads and dioctyl phthalate (DOP) fuel blends on particulate emissions and soot structure were examined. The results show that the particle number and mass concentrations are higher for DOP fuel blends compared to neat diesel. The soot structure of DOP fuel blends is more compact and exhibits shorter and curved fringes compared to diesel. The oxidation reactivity of soot particles is reduced in DOP fuel blends.

Summary: This study investigates the light absorption, potential sources, and health risks of black carbon (BC) and brown carbon (BrC) during the prescribed burning season in Brisbane. It was found that fossil-fuel combustion contributes more to the total BC, while biomass burning has the potential to form more secondary BrC. Air masses from southern and northern Brisbane were identified as potential pollution sources dominated by biomass burning and traffic emissions. The health risks based on equivalent numbers of passively smoked cigarettes increased during periods with elevated BC emissions, likely from prescribed burns.

Summary: Exposure to particulate matter (PM) has been linked to negative health effects in numerous epidemiological studies. It is known that the harmful effects of particles cannot be explained solely by particle mass, as their chemical composition and reactivity are not always reflected by mass loadings. The oxidative potential (OP) of aerosol particles shows promise as an indicator of their potential toxicity. Source apportionment (SA) studies of PM are increasingly used to develop strategies and regulations for improving air quality, but less attention has been given to SA investigations of OP. This review summarizes previous research on SA of atmospheric PM OP and provides guidelines for future studies.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
