PM10 fine-particle levels, a key
indicator of smog, were over the limit at 11 out of 13 stations
in Rome on Thursday, environmental agency ARPA said Friday.
Car bans have been in force in the Italian capital since
Tuesday.
These have covered diesel cars even up to Euro 6 ones.
On Monday the number of stations over the limit for PM10s was
eight out of 13.
On Tuesday and Wednesday it was nine out of 13.
ARPA said the worsening was due to a lack or wind and rain
that could have swept some of the particles away.
Today's weather forecasts sees atmospheric conditions in Rome
improving form Saturday.
ARPA said PM10 levels should start returning within normal
limits from the start of next week.
On Sunday Rome will have an 'ecological' car-free day.
