“…Injury to the area exposed to H2SO4 was reported to be of the type associated with photochemical oxidants. The present experimental exposure resulted in marginal necrosis, which is different from the necrotic blotching previously reported 25 as the result of exposure to H2SO4 in droplet form. This may be due to an energy dependent translocation of sulfate ions.…”

“…In simulated acid rain experiments, Haines et al (1980) found a threshold of leaf damage for most species tested in a pH range 2.5 to 2.0 and for Pinus strobus needles at pH 1.0 to 0.5. Wood and Borrnann (1974) observed foliar tissue damage at pH 3 for misting of yellow birch seedlings: significant growth decreases occurred when acidic exposure (pH 2.3) was initiated during the germination stage. Thomas et al (1952) reported cases in which plant injury was not initially caused by concentrated H,SO, aerosol-apparently due to its high surface tension-but followed surface wetting by fog.…”

Highly concentrated, acidic stratus cloudwater was monitored as it intercepted a pine forest (Henninger Flats) 25 km northeast of Los Angeles. Observed pH values ranged from 2.06 to 3.87 for over 100 samples collected in 1982 and 1983 with a median value below pH 3. The ratio of nitrate/sulfate in cloudwater samples was between 1.5 and 2: rainwater at the same site had a ratio of approximately I. The solute deposition accompanying several light. spring rains (summing to -1 '%I of annual rainfall) was a disproportionate fraction of the annual total: H'. NO, and SO: were -20% or more. Based on a reasonable estimate of fog precipitation, deposition of sulfate, nitrate and free acidity due to intercepting stratus clouds may be of comparable magnitude as that due to the incident rainfall at Henninger Flats.Cloudwater that had deposited on local pine needles was collected. It was in general more concentrated than ambient cloudwater but with comparable acidity. Enrichment of K ' and Ca" in those samples and in throughfall is believed to be due to leaching from foliar surfaces. Injury to sensitive plant tissue has been noted in the literature when prolonged exposure to this severe kind of micro-environment has been imposed.

“…Acid rain is the term used in environmental science that represents mixing of environmental pollutants with the rain water (Wood, and Bormeann, 1994). The mixing raises the acidity of rain water by formation of acid following chemical reactions involving pollutant gases and water.…”

This study was conducted to investigate the influence of acid rain and environmental problems on the teaching of Biology in schools in the riverine communities of Akwa Ibom State -Nigeria. One hundred and eighty (180) Biology teachers were selected using the stratified sampling technique. A questionnaire titled "Acid rain and Teaching of Senior Secondary Biology" (ARTSSB) was used to collect data for testing the four null hypotheses of the study at .05 level of significance. Data analysis was done using the t-test statistics. Findings were made that the damage of buildings by acid rain, the destruction of forest by acid rain, the devastation of arable land by acid rain and the acidification of surface and domestic waters by acid rain all had a significant influence on the study of senior secondary Biology. Recommendations were made among others that: the ecology component of the Biology curriculum for secondary schools should be effectively taught; important environmental issues including acidification of environment by acid rain should be incorporated into the senior secondary curriculum and be carefully thought by teachers of Biology.
