TL;DR: In this article, the influence of the fuel mixture on vehicle exhaust emissions operating under the New European Driving Cycle (NEDC) and in hot operating conditions was analysed, and the authors found that the VOC speciation analysis suggests that the set of VOC present in exhausted gases is clearly fuel dependent.

TL;DR: Data indicated that exposure levels during firefighting activities were beyond limits recommended by the Occupational Exposure Standard (OES) values, with a significant increase in CO and decrease in NO in exhaled air of majority of the firefighters.

TL;DR: These are the first measurements and analysis of firefighter's individual exposure to toxic gases and particles in fire smoke experiments in Europe, and indicate that urgent measures to avoid these levels of exposure are needed.

TL;DR: In this article, the authors evaluated the exposure of students to traffic-emitted carbon monoxide (CO) in their daily walk to school, with a particular emphasis on the effect of trees and route choice.

TL;DR: In this article, the effects of low biodiesel blends in performance, fuel consumption and NO x emissions were investigated during tests carried out with a Renault Megane 1.5ci equipped with recent injection and exhaust emission control technologies.
