Why Diesel Particulates Cause Cardiovascular Disease

Monday, June 9th, 2008

Particulates in diesel exhaust are a substantial cause of the negative health effects traced to air pollution, above all in traffic environments. Diesel exhaust contains a number of extremely tiny particles about 1/10,000 mm in diameter, with chemical compounds bound to the surface that have been suggested to lie behind the ability of these particles to cause harmful health effects.

Individuals with lung or heart disease are especially vulnerable and are impacted most negatively during periods with high levels of air pollution. In his dissertation, Håkan Törnqvist studied the effects of diesel exhaust on healthy individuals and respective patient groups with chronic obstructive lung disease (COL) and coronary disease with atherosclerosis in the coronary artery.

The aim of the studies in the dissertation was to use controlled exposure studies to try to elucidate the mechanisms that explain why diesel exhaust particulates in polluted air cause increased morbidity in both lung and heart diseases. The studies were carried out in an exposure chamber, where the individuals were exposed for one hour to, respectively, diesel exhaust with a particulate concentration of about 300 µg/m3 and filtered air. The two exposures were in random order, so the individuals served as their own controls.

Cost of diesel hurting carriers

Wednesday, May 7th, 2008

The high cost of diesel has put Atlantic Canada’s trucking industry between a rock and a hard place. Industry executive Shane Esson more aptly describes it as being in survival mode.

Skyrocketing diesel prices have put several Atlantic companies in a precarious financial position and any short-term relief is not on the horizon.

Diesel prices have increased as much as 50 per cent in the past year and trucking companies are paying in excess of $20,000 a year more per truck for fuel over last year.

“There are a lot of carriers who are right now operating at a loss,” says Mr. Esson, general manager of Keltic Transportation of Moncton. And if there are any companies making money, it’s very minimal, he says.

Bio-diesel tractors from TAFE

Saturday, April 26th, 2008

Tractors and Farm Equipment (TAFE) on Friday said its entire sub 100 HP range of Massey Ferguson tractors, but one, has been made compatible for use with bio diesel.

“These tractors can use the current five per cent blend of regular diesel with diesel produced by esterising vegetable
oils obtained from corn, jatropha, rape seed etc,” TAFE said in a statement.

Fuel shortage forces UN to halt food handouts in Gaza

Thursday, April 24th, 2008

The UN is to halt food handouts for up to 800,000 Palestinians from today because of a severe fuel shortage in Gaza brought on by an Israeli economic blockade.

John Ging, the director of operations in Gaza for the UN Relief and Works Agency, which supports Palestinian refugees, said there had been a “totally inadequate” supply of fuel from Israel to Gaza for 10 months until it was finally halted two weeks ago. “The devastating humanitarian impact is entirely predictable,” he said.

China replaces petrol, diesel oil with bio-ethanol fuel in 10 localities

Tuesday, April 1st, 2008

South China’s Guangxi Zhuang Autonomous Region became the 10th Chinese locality to have replaced gasoline and diesel oil with bio-ethanol fuel on Tuesday out of environmental and energy efficiency concerns.

Petrol stations in all the 14 cities of Guangxi began to sell bio-ethanol fuel on Tuesday and in two weeks, traditional petrol and diesel oil will be phased out, said Fu Jian, an official in charge of transport with the regional government.

Fu said about 350,000 motor vehicles and more than 3 million motorbikes will have their tanks cleaned up for the fuel change.
