Hydrogeochemistry of rivers and lakes
This chapter has three principal objectives: (1) to summarize the present chemical composition of North American surface waters and point out any discernible trends with time; (2) to review chemical and biochemical principles and processes that control natural water composition, and the ways in which these may be involved in attaining the particular chemical compositions and trends that we can obs

Origin of solutes in saline lakes and springs on the Southern High Plains of Texas and New Mexico
Analysis of hydraulic heads, calculation of pore volume flushing, and analysis of solute and isotopic chemistry strongly suggest that the solutes originate from the concentration by evaporation of runoff and potable shallow ground water that discharges from the High Plains aquifer. Chloride/bromide solute ratios, which are thought to be unaffected by mineral precipitation or sorption, average 160

An expert system for prediction of aquatic toxicity of contaminants
The National Fisheries Research Center-Great Lakes has developed an interactive computer program in muLISP that runs on an IBM-compatible microcomputer and uses a linear solvation energy relationship (LSER) to predict acute toxicity to four representative aquatic species from the detailed structure of an organic molecule. Using the SMILES formalism for a chemical structure, the expert system ident
