Objetivo TO INVESTIGATE THE INTERACTION BETWEEN OZONE AND VARIOUS FORMS OF ACID DEPOSITION ON AGRICULTURAL AND TREE SPECIES. : PLANTS WILL BE EXPOSED IN A CHAMBER WITHIN A CONTROLLED ENVIRONMENT CABINET UNDER CONTROLLED LIGHT, TEMPERATURE AND HUMIDITY CONDITIONS, TO A RANGE OF RAINS, AEROSOLS MIST OR FOGS OF VARYING DROPLET SIZE AND CHEMICAL COMPOSITION THE EXPOSURE CONDITIONS WILL BE CHOSEN TO REPRESENT REALISTIC CONDITIONS, SIMILAR TO THOSE WHICH OCCURRED IN THE PAST YEARS IN UK AND OTHER EUROPEAN COUNTRIES, SPECIALLY AS REGARDS TO CONCURRENT RECORDS OF OZONE CONCENTRATIONS AND OF THE PH, THE SULPHATE AND THE NITRATE CONTENTS OF PRECIPITATION. TWO SERIES OF EXPERIMENTS WILL BE CARRIED OUT. SHORT TERM EXPERIMENTS, USING AGRICULTURAL AND HORTICULTURAL SPECIES, WILL EXAMINE THE NATURE OF THE INTERACTION BETWEEN OZONE AND ACID PRECIPITATION UNDER DIFFERENT CONDITIONS. THE EFFECTS OF FACTORS SUCH AS OZONE CONCENTRATION, THE CHEMICAL COMPOSITION AND PHYSICAL FORM OF THE PRECIPITATION, AND THE TIMING OF EXPOSURES ON PLANT RESPONSES, MEASURED AS VISIBLE INJURY, GROWTH RATE, WILL BE DETERMINED. THE SECOND SERIES OF EXPERIMENTS WILL INVOLVE A NUMBER OF IMPORTANT BRITISH TREE SPECIES EXPOSED TO RELATIVELY LOW LEVELS OF OZONE AND ACID PRECIPITATION OVER THE COURSE OF A GROWING SEASON. ONLY A LIMITED NUMBER OF EXPERIMENTAL TREATMENTS, IDENTIFIED ON THE BASIS OF THE FIRST SERIES OF EXPERIMENTS AS BEING OF PARTICULAR INTEREST, WILL BE ACHIEVED FOR A LONGER PERIOD OF TIME.
