GIS Analysis of Surface Water Chemistry Susceptibility and Response to Industrial Air Pollution in in the region. After correction for sea salt, acid-neutralizing capacity (ANC) of waters was calculated. The highest concentrations of anthropogenic non-sea sulfates were confined to the districts with high cation concentrations (Na. + K. + Ca. + Mg.) that reduced negative effects. The most vulnerab

Effects of Atmospheric Sea-Salt Deposition on Soils and Freshwaters in Northeast Scotland,ering for the soils within the catchment upstream of the sampling point. Representative soil samples from the LFH, AE, B and C horizons and on 4 different parent materials have been obtained from the surrounding catchments to validate the above results for associated soil solutions. Sampling took pl

Effect of Chronic Nitrogen Additions on Soil Nitrogen Fractions in Red Spruce Stands,l N), and NH.-N (9–13% of total N). Rates of atmospheric deposition varied greatly among the four stands. Ammonium N and amino acid N concentrations in the Oie horizon were positively related to wet N deposition, with respective r. values of 0.92 and 0.94 (n = 4, . < 0.05). These relationhips were s

An Empirical Approach for Assessing the Relationship between Nitrogen Deposition and Nitrate Leachid sites the predicted NO. concentrations closely matched measured values. At the fifth site, where most subcatchments were forested, the deposition function and DOC:DON ratios gave conflicting predictions and both methods generally underestimated measured NO.. concentrations.
