The effects of acidic deposition on Alberta agriculture : a review /

“…Most researchers have reported additive or synergistic effects (Tingey et al 1971b; Bull and Mansfield 1974;Hill et al 1974;Masaru et al 1976;Ashenden and Mansfield 1978;Ashenden 1979;Ashenden and Williams 1980;Irving et al . 1982;and Reinert and Sanders 1982), and a few have observed antagonistic effects (Thompson et al 1980;Reinert and Sanders 1982;and Whitmore and Freer-Smith 1982).…”

The Effect of Coal Utilization Emissions on Natural and Man-managed Terrestrial and Freshwater Ecosystems

Even in the presence of an abundant water supply permitting maximum stomatal opening there was generally a very high level of tolerance to both pollutants.…”

Synergistic effect on field-grown soybeans from combinations of sulfur dioxide and nitrogen dioxide

“…A number of researchers have reported nonaclditive (synergistic or antagonistic) responses of plants to combinations of air pollutants (Tingey et al 1971;White et al 1974;Ashenden and Williams 1980;Thompson et al 1980;EIkiey and Ormrod 1981). Most of these studies utilized exposures of high concentration and frequency in controlled environments.…”
