text: Paris has recently set a partial driving band in there city because of record pollution levels that were being caused by automobiles. The smog in paris had become so intense and severe that they had to create a driving band to correctly limit the pollution being made. "...Paris had 147 micrograms of particulate matter (PM) per cubic meter compared with 114 in Brussels and 79.7 in London."(Source 2,17). This extremly high smog ratio and prooves the pollutin from automobiles is causing the problem because after a week with the band the smog had almost cleared fully.
