Title: Criteria of evaluation of anthropogenic changes and calculation of the anthropogenic component of the dissolved load of rivers

Abstract

Considerable amounts of chlorine and sodium enter river waters during exploration and operation of oil and gas fields due to lifting highly mineralized formation waters to the surface (the Volga-Ural gas and oil region). Urban and agricultural wastewaters are sources of entry for the components of a salt composition. Magnesium and sulfate ions are considerably inferior to chlorine and sodium with respect to the intensity of involvement in technogenic geochemical flows. Criteria of anthropogenic eutrophication at an early state, methods of separating natural and anthropogenic components of the biogenic runoff (nitrogen and phosphorus compounds) of rivers, and methods of their quantitative calculation have been developed. The results of the calculations for all ions are given. The anthropogenic component of the dissolved load successfully increased. Total dissolved load of the Volga reaches 22%.

  • Botanical monitoring is a subsystem of biosphere monitoring and a permanent service for tracking the condition and level of anthropogenic changes in vegetation, primarily at sites of particularly intense economic exploitation. The need for monitoring is established in this paper, in connection with its increasing alteration under human influence. The theoretical and methodological principles of botanical monitoring, the estimation of the level of vegetation degradation, and the prognosis for anthropogenic transformation are described. The authors conclude that there is an urgent need both for botanical monitoring and for the training of those capable of monitoring the condition of our plantmore » cover.« less
  • The fixation of atmospheric N{sub 2} by industrial and agricultural activities has risen dramatically in recent decades, leading to large increases in N inputs to terrestrial and aquatic ecosystems, particularly across much of the U.S. and Europe. We pooled the watersheds draining into the North Atlantic Ocean into 14 major basins, and compiled available data to estimate river N fluxes to the coast, atmospheric N deposition, application of N fertilizers, leguminous crop N fixation, and the net movement of N in food and feed for each of the 14 basins. We also used data on river N from relatively undisturbedmore » regions along with modeled values for pre-industrial N deposition to estimate pre-industrial river N fluxes from each watershed basin. Our analysis suggests that river N fluxes in most North American and European basins have increased 5-20 fold since pre-industrial times, and shows that they are highly correlated with the sum of all anthropogenic N inputs to the basin. Finally, despite the substantially elevated river values, only about 20-25% of total anthropogenic N atmospheric, terrestrial and groundwater sinks.« less
  • The concentration and {sup 18}O:{sup 16}O ratio of dissolved oxygen were measured for 23 rivers and lakes of the Amazon Basin during 1988, 1990, and 1991. With only two exceptions, the rivers and lakes had dissolved oxygen concentrations that were at 20-90% of atmospheric saturation levels. The {delta}{sup 18}O of the dissolved oxygen ranged from 15 to 30% (vs. SMOW). The {delta}{sup 18}O for the lakes were the lowest at 15-23%. {delta}{sup 18}O < 24.2{per_thousand} (the atmospheric equilibrium value) are the result of photosynthetic oxygen input. The {delta}{sup 18}O of the rivers, in contrast, ranged from 24 to 30{per_thousand} >more » 24.2{per_thousand} resulted from respiration. Despite this clear difference between the {delta}{sup 18}O for rivers and lakes, these water bodies had similar levels of oxygen undersaturation. The {delta}{sup 18}O and dissolved oxygen concentrations are used to determine the ratio of community respiration (R) to gross photosynthesis (P) rates. R:P varied between {approximately}1 and 1.5 for lakes and between 1.5 and 4 for rivers. For all rivers and lakes, the measured {delta}{sup 18}O indicated the presence of photosynthetically produced oxygen, with the highest proportion occurring in lakes. The {delta}{sup 18}O of dissolved oxygen is a unique tracer of photosynthetic oxygen and provides, through a determination of R:P, a means of quantifying the heterotrophic state of freshwaters. 29 refs., 8 figs., 4 tabs.« less
  • The quality of the U.S. Army corps of Engineers` (Corps) total dissolved gas (TDG) data base for the 1995 spring spill season was reviewed to determine the value of this information if real-time management decisions regarding river operations. We concluded that problems in transmitting, archiving, correcting and interpreting the records constitute significant sources of data anomalies that affect the accuracy and reliability of information necessary to manage spill and TDG in the Columbia and Snake rivers. The data base that was reviewed covers 25 selected Columbia and Snake river stations, and includes real-time TDG data needed to regulate spill operationsmore » to maintain gas levels within state water quality standards and to monitor effects on fish and aquatic life during the salmon migration season. A wide range of anomalies (daily averages missing or in error or based on incomplete records) was detected in more than one-third (37 percent) of the Corps` gas data base. Extreme anomalies (daily averages including errors and discontinuities for more than eight hours in a day) were found in 16 percent of the data base. The Fish Passage Center, also reviewed the Corps` data and reported an overall 33 percent incidence of anomalous days. Despite arriving at similar findings about the Corps` data base, we detected a 28 percent discrepancy in the type of data anomalies between our analyses. 14 refs., 1 fig., 4 tabs.« less
