But Steward T. A. Pickett, a colleague of Dr. Gregg's and Dr. Jones's at the Institute of Ecosystem Studies, said the research was significant because of the complexity of the situation, the many pollutants and effects considered, and the "very elegant and controlled way" that the action of ozone emerged from a welter of other influences.
The new rule required about half the states to reduce their emissions of sulphur dioxide, nitrogen oxide and other emissions based on projections of how many pollutants were crossing state lines, and told them how to do it.The states affected argued that this was an unfair burden.
Because many pollutants are regulated separately, designing inter-pollutant markets requires considering pre-existing regulatory constraints.
River inflows contribute many pollutants, thereby tending to induce ecological and hygienic problems (Wang et al. 2007).
