‘The implications of increasing CO2 for human health are clear’
FRISCO — Those sniffly, sneezy summer days are about to get a lot worse for allergy sufferers. Some types of grass pollen and exposure to allergens could increase by more than 200 percent in the next 100 years, due to predicted rises in carbon dioxide and ozone, according to University of Massachusetts Amherst scientists, who project a significant, worldwide impact on human health.
In their study of Timothy grass, environmental health researchers tried to determinedthe interactive effects of CO2 and ozone at projected higher levels on pollen production and concentrations of a Timothy grass pollen protein that is a major human allergen. The findings are reported in the current issue of PLOS ONE.
