Default Vehicle pollution

I develop a cough from regularly having to ride in heavy traffic. A
Respro mask helps reduce this significantly, but is of course disgusting
to wear.

I assumed this cough was caused by diesel pollution, but now I hear that
approximately 50% of particulate vehicle pollution comes from tyre wear.

Apparently a team in London are developing a device that can reduce this
tyre pollution significantly. They use electrostatics to capture the
pollution as it is given off by the tyres.

This is why Gavin Loathsome wants to ban all gasoline cars by 2035, because it will save so much pollution.

As an aside, that is a big issue for regulated businesses with parking lots/loading docks and storm drains. Regulated business must have NPDES stormwater permits, and the general permits limit the amount of metals you can put down the drain, assuming it's draining to a navigable water way -- which most do around here. Tires slough a huge amount of zinc, among other metals. A lot of the parking lot sweeping you see around here is to catch the metals and prevent them from going down a storm drain to an outfall and into one of the rivers.

Here in Iowa our big concern for us big city folk is all the pesticides and fertilizer from farm fields that run off into the streams and eventually into the rivers where Des Moines gets its drinking water from. Of course all the rural folk scream and yell when the big capital city tries to keep the rural folk from polluting the water.

Here in Thailand there is the same problem. The government is
enforcing a ban of the use of paraquat and chlorpyrifos and has
ordered those that posses the chemicals return them to the dealer from
which they were purchased. And, of course the farmers are bitching and
shouting, but just yesterday the news had it that the U.S. government
has protested this in an official letter from the U.S. Embassy to the
Thai Prime Minister.

The Thai Minister of Health, when asked about the controversy, stated
that "the US was worried about trade. The Thai government was
concerned about the health of Thai consumers".
