Five varieties of rice ( Oryza sativa L.) of varying salinity resistance were grown in non-saline and in saline conditions, with and without a repeated exposure to ozone at a concentration of 83 nmol mol −1 giving an AOT40 (cumulative exposure above 40 nmol mol −1 ) of 3600 nmol mol −1 h....
Rooted cuttings of clonal Sitka spruce ( Picea sitchensis (Bong.) Carr.) were grown from April to October in 1 m long tubes sunk into the ground inside open top chambers. The same experiment was repeated in each of two consecutive years using a different clone of Sitka spruce each year. Air was...
The effects of prolonged simulated acid rain on the biochemistry of Scots pine needles were studied in Finnish Lapland. Pine trees were exposed by spraying the foliage and soil with either clean water or simulated acid rain (SAR; both sulphuric and nitric acids) over the period 1985–1991. The...
Wild rodents (Mus domesticus) were collected in three areas in Rome exposed to different traffic flows to ascertain a possible correlation between genetic damage and heavy metal concentration. The concentration of lead, cadmium and zinc were determined in liver, kidney and bones and two...
Experiments were conducted to examine the effects of the anti-ozonant ethylenediurea (EDU) and chronic ozone (O 3 ) exposure on leaf physiology and senescence in an O 3 -sensitive potato cultivar ( Solanum tuberosum L. cv. Norland). A dose-response experiment showed that an EDU concentration of...
Spatial and temporal distribution of methylmercury (MeHg) was determined in surficial sediments collected from a river-reservoir system impacted by Hg-contaminated mine wastes. Despite the fact that total mercury concentrations (Hg T ) in surface sediments of the Carson River system were in the...
The objectives of this study are to characterize different PAH-pools (soil horizons, microsites influenced by stem flow, aggregate core and surface fractions, particle size fractions) in soils affected by depositions. Three forest soils affected by the emissions of an aluminium plant near...
Atmospheric PCBs were monitored around a site of stored used capacitors in a suburb of Bangkok, Thailand, from October 1991 to November 1992. Higher concentrations (820 ng/m 3 on average) were observed near by the storage area compared to those at 5 m leeward side (570 ng/m 3 ) while the...
