Beyond a One-Time Scandal: Europe’s Onging Diesel Pollution Problem
نویسنده
چکیده
More than half the European passenger fleet is diesel-powered. Although the European Union has been progressively tightening vehicle emissions for decades, new diesel cars still produce on-road nitrogen oxide emissions that far exceed the current standard. Efforts to reduce diesel emissions would likely make the cars more costly, but experts say it can—and should—be done.

A Time Dependent Pollution Routing Problem in Multi-graph
This paper considers a time dependent(the travel time is not constant throughout the day) pollution routing problem (TDPRP), which aids the decision makers in minimizing travel time, toll cost and emitted pollution cost. In complexity of urban areas most of the time one point is accessible from another with more than one edge. In contrast to previous TDPRP models, which are designed with only ...
متن کاملNear-frictionless Carbon Coatings for Use in Fuel Injectors and Pump Systems Operating with Low-sulfur Diesel Fuels
While sulfir in diesel fuels helps reduce friction and prevents wear and galling in fuel pump and injector systems, it also creates environmental pollution in the form of hazardous particulate and S02 emissions. The environmental concern is the driving force behind industry’s efforts to come up with new alternative approaches to this problem. One such approach is to replace sulfur in diesel fue...

Soil pollution by oil compounds is one of the most common environmental problems. To study the effect of four different treatments of soil diesel pollution and diesel degrading bacteria (control, diesel, one bacterium and three bacteria) on some growth and biochemical factors of two cultivars of Zea mays (704 and 640) a factorial research was undertaken in the form of a completely randomized de...

19 In 2002, Lonely Planet changed the cover of its travel guide to Hong Kong and Macau from a brightly colored temple to the Bank of China building silhouetted against a hazy sky. Inside, the guide tells visitors with respiratory conditions to consider “dangerously high levels of particulate matter and nitrogen dioxide” when planning to stay “for a prolonged period, particularly in summer” (But...
متن کاملAir pollution and thrombosis: an experimental approach.
Air pollution is associated with cardiovascular mortality. Inhaled ultrafine particles translocate into the blood. Amine-polystyrene ultrafine particles significantly enhance experimental thrombus formation in a damaged hamster vessel and shorten the closure time in the Platelet Function Analyser. Diesel exhaust particles are thrombogenic within one hour of intratracheal instillation and shorte...
