Figure 1a shows that the relationship between sulfurdioxide concentrations and freedoms is nearly linear. They contribute 16 per cent of all particulate matter pollution, and 43 per cent of all sulfurdioxide. In 1993, the environmental standards for some air pollutants such as sulfurdioxide and carbon monoxide were tightened. Second, pollution levels are negatively correlated with freedom with one small exception: sulfur dioxide concentrations are about the same for countries with low and medium political freedoms. The major result is that the costs of reducing sulfurdioxide, and perhaps also dust, are likely to be substantially lower in transition countries than in the west. We find that freedoms are statistically significant for measures of pollution that directly affect human health: concentrations of sulfurdioxide, smoke, heavy particles, and fecal coliform. The natural and usually impure cinnabar was chemically separated into mercury and sulfurdioxide and then resynthesized for transportation or to produce pure cinnabar for use as a pigment. Sulfurdioxide, while harmless to healthy individuals, can induce asthma when inhaled or ingested by sensitive people.
