Effect of storm type on rainwater composition in southeastern North Carolina

Stimulation of phytoplankton production in coastal waters by natural rainfall inputs: Nutritional and trophic implications

“…Paerl 1986, Willey et al 1988) and in other regions of North America (Likens et al 1972, NADP 1987, Underwood et al 1989. The studies by Willey and Paerl (1986), Willey et al (1988) and Underwood et al (1989) showed a similar relationship between pH and [NO3] and, additionally, described a strong relationship between pH and sulfate enrichment in precipitation. The relationship between pH, [NO;-], and sulfate attests to the general importance of nitric (HNO3) and sulfuric acids (H2804) as key components of acid precipitation falling in this coastal region, as well as other regions of eastern North America.…”

“…Precipitation downwind of urban and industrial centers, known to be sources of enhanced atmospheric nitrogen emissions (Likens et al 1972, Galloway et al 1984, represents an appreciable source of growth stimulating nutrients (Paerl 1985, Duce 1986. Previous surveys have shown the mid-Atlantic region to be a frequent recipient of nitrogen-enriched precipitation (NADP 1987, Weathers et al 1988, Willey et al 1988. The importance of atmospheric deposition as a nitrogen source is expected to increase substantially as we enter the next century.…”

Effect of Disc Filtration with and without Addition of Flocculent on Nano- and Micro-Particles and Their Associated Polycyclic Aromatic Hydrocarbons in Stormwater

“…Table 1 shows an overview of the physical parameters measured for each sample. The pH of rainwater is normally found to be in the range of 4.0-4.9, with the lowest pH found under summer thunderstorms (e.g., [28]). The pH of the total deposition collected in campaign 1 (autumn) was found to be 3.5, while the deposition collected in campaign 2 (spring/summer) had a pH of 6.2.…”

Sources of Pollution in Rooftop Rainwater Harvesting Systems and Their Control

“…Numerous other studies (Bridgman, 1992;Bucheli et al, 1998a;Bucheli et al, 1998b;Förster, 1998Förster, , 1999Garnaud et al, 1999;Loye-Pilot and Morelli, 1988;Willey et al, 1988;Zhong et al, 2001) have also demonstrated relationships between concentrations of chemical contaminants and proximity to contaminant sources (emissions), weather patterns, and atmospheric transport and deposition. Aerobiological studies, reviewed by Lighthart (2000) and Jones and Harrison (2004), have repeatedly demonstrated the effect of seasonal and meteorological influences on atmospheric concentrations of bacteria and fungal spores.…”
