At schools, we don't just need to
think about buses idling. Every morning and afternoon there are many
parents picking up or dropping off their children, sitting around
with their engines idling.
In the morning, idling is not
usually as much of a problem, as during the afternoon. This is due
to the parents or caregivers just dropping the children off and then
moving on. In the afternoon however, some parents arrive 10-15
minutes before school is out and sit with their engines idling.
Depending upon the size and layout
of the school, parent idling can become a serious problem. The
larger the school, the more parents and caregivers are likely to
arrive to pick up children. Some schools are arranged in a way that
cars may be lined up close to the exits so that students walk
straight into the fumes. In other schools, due to the number of
students being picked up, some vehicles may be blocked in for a
period, and sit with engines idling.
Cars and SUVs release a number of
air pollutants into the air that are detrimental to health. These
sulfur oxides (SOx),
oxides (NOx), volatile organic compounds (VOCs),
monoxide (CO) and
such as mercury. Besides direct effects on respiratory and
cardiovascular health, some of these chemicals also combine in the
atmosphere to produce
acid rain and
ground-level ozone or smog.
Why People Idle
There are many reasons why people
idle their vehicles, such as to listen to the radio, convenience,
parked illegally, or to keep the heat/a.c. on. Another reason is because
people often do not know the facts about idling, such as,
10 seconds of idling uses more fuel than
turning off the engine and restarting it.
