Exhaust Fumes and Inflammation
I woke up this morning with a sore throat, and then remembered that yesterday I had been doing some errands on my mountain bike in Dipolog city. I use my bike as the city is not designed for cars but has hundreds of motor scooters and tricycles all of which pump out fumes.
As roadways choke on traffic, all these tailpipe fumes are already implicated in heart disease, cancer and respiratory ailments—may also injure brain cells and synapses key to learning and memory.
No one knows whether regular commuters breathing heavy traffic fumes suffer any lasting brain effect. Researchers have only studied the potential impact based on where people live and where air-pollution levels are highest. Even if there were any chronic cognitive effect on drivers, it could easily be too small to measure reliably or might be swamped by other health factors such as stress, diet or exercise that affect the brain, experts say.
Recent studies show that breathing street-level fumes for just 30 minutes can intensify electrical activity in brain regions responsible for behaviour, personality and decision-making, changes that are suggestive of stress, scientists in the Netherlands recently discovered. Breathing normal city air with high levels of traffic exhaust for 90 days can change the way that genes turn on or off among the elderly; it can also leave a molecular mark on the genome of a newborn for life, separate research teams at Columbia University and Harvard University reported last year.
Maybe my sore throat is the least of my worries, it will clear up in a couple of days, but the quality of my life is suffering from something outwith my control. Yes I live in a relative traffic free gated community, but I still have to to go into the city for supplies, I might have to consider using a mask but that would make breathing harder, so then I can not ride as fast and so prolong my exposure, its a dilemma with no easy answer.
