Pain without gain

If 32% of mercury deposition in Canada comes from domestic emissions and 25% of these are from coal-fired power plants, the complete elimination of coal-fired power plants would result in an average decline of 4% in the level of mercury in fish. [...] Lutter and Mader [2001] estimated the change in scores on various tests used in the studies of the Faroe Islands and New Zealand based on the regression coefficients reported in the studies. [...] In contrast to the results of the Faroe Islands and New Zealand studies, a study of mothers and children in the Seychelles suggests that mercury exposures similar to levels in the Faroe Islands and New Zealand, and much higher than occur in Canada or other western countries, have no effect on health. [...] Third, although the mercury levels in the Seychellois and the Faroese are simi- lar, the whale blubber eaten by the Faroese has about five times the mercury per unit mass as the fish eaten by the Seychellois. [...] The IMO selects suppliers in order of increasing prices and the price at which the supply is sufficient to cover demand is paid to all the successful suppliers.
