Abstract:

Normal metabolism results in a net acid production of approximately 1 mmol/kg day−1. Physiological pH is regulated by excretion of this acid load (as carbon dioxide) by the kidneys and the lungs. A series of buffers in the body reduces the effects of metabolic acids on body and urine pH. For acid–base disorders to occur, there must be excessive intake (or loss) of acid (or base) or, alternatively, an inability to excrete acid. For these changes to result in a substantially abnormal pH, the various buffer systems must been overwhelmed. The pH scale is logarithmic, so relatively small changes in

Abstract:

This chapter draws up the abiotic frame for organisms set by the physical and chemical properties of a specific ecosystem. The abiotic frame is a combination of several features, including wind, turbulence, temperature and light, but also by nutrient status, pH and oxygen supply. Based on this abiotic frame, large-scale movements, as well as stratification phenomena of lakes are discussed. The importance of the surrounding land, that is, the catchment area, is stressed; specifically, how the catchment area may strongly affect the physical and chemical features of the lake or pond.

Another important property, pH, has direct effects on organisms and indirect effects via how hydrogen ions determine the chemical form of key molecules and compounds in nature.

Abstract:

Soil reaction is the amount of acids (acidity) or bases (alkalinity) present in a soil and is indicated by a term called “pH”. By definition, pH is the logarithm of the reciprocal of the hydrogen ion (H+) concentration, or When a number has a smaller superscript number with it, the number is raised to that power which is called the “logarithm.” Raising a number to a power means multiplying that number by itself the number of times indicated by the superscript. . . . Examples: 102 means 10 x 10 = 100; 103 means 10 x 10 x 10 = 1,000. The logarithm (log) is 2 for the first example and 3 for the second. . . . Logarithms are used as these are more convenient in expressing the amount of hydrogen ions present. Under neutral solutions the pH is 7.0. Any pH that is less than 7 is acid and any pH above is alkaline. When changing from a pH of 7 to a pH of 6, the H ion concentration increases ten times, and when going from a pH of 7 to a pH of 5, the H ion concentration increases 100 times because pH uses a geometric scale and not an arithmetic scale. Thus, pH changes by steps of ten times the next adjacent number. The logarithmic scale used for pH is the same type, but opposite in direction, as that used to measure earthquakes. For each larger number of earthquake, the severity increases ten times; for each smaller number of pH, the acidity increases ten times. Some plants can tolerate very low pH (4.5) and others can withstand a pH of 8.3, but the optimum range for growth of most plants and microbes is between 6 and 7. Availability of most nutrients is affected by pH changes. Charts have been constructed to show this relationship. On these charts the pH at which most nutrients are readily available is from 6 to 7. At extremes of pH, availability of nutrients to plants often is reduced considerably.

Abstract:

<em>Abstract</em>.—Historic coal mining operations throughout the United States left behind a legacy of waterways polluted by abandoned mine drainage (AMD). Streams polluted by AMD typically have low pH and high concentrations of heavy metals such as aluminum, iron, and manganese, creating toxic environments for aquatic organisms and causing many of these environments to be devoid of aquatic life. This chapter details the large-scale restoration efforts underway since 2004 in the West Branch Susquehanna River watershed in north-central Pennsylvania to remediate AMD. It provides an overview of the historical coal mining throughout the watershed and the types of restoration projects that have been completed. The importance of establishing and maintaining partnerships for large-scale restoration projects is emphasized along with a discussion on how these projects have been monitored and maintained to ensure restoration success. This chapter aims to provide guidance in the development of other large-scale restoration projects through the lessons learned over the past 15 years of restoration in the West Branch Susquehanna River watershed.

Abstract:

Due to the insufficiency of freshwater resources and to supply the drinking water populations, many desalination processes such as reverse osmosis, electrodialysis and distillation are widely used. However, these processes are of large-scale consumers of energy and confronted with various problems such as corrosion and scale formation. In most cases, scales are made of calcium carbonate CaCO3. In the present chapter, an overview on the effect of operating parameters such as temperature, pH and supersaturation on the precipitation kinetics, microstructure, and polymorphism of CaCO3 is given. Additionally, I put special emphasis on the effect of foreign ions such as magnesium, sulphate, and iron ions on CaCO3 precipitation since they are present at significant concentrations in natural waters. Also, the mechanisms by which these ions affect the crystal growth of CaCO3 were pointed out. Knowledge about these operating parameters as well as the effects of foreign ions allow elucidating the polymorphs growth during water treatment. The control of these operating parameters allows reducing scale formation during drinking water and wastewater treatment. The economic impact is of greatest importance since this favorably affects the treatment costs, increases the equipment life, and allows enhanced product water recovery.

In Southwest Louisiana, the Calcasieu Lake and surrounding water systems are the major fresh water sources to the nearby coastal wetlands and agricultural areas.

The health of the wetland vegetation is essential to the wetland losses in the area. One of the major problems related to the health of marshes is the nutrient deficiency. In addition, the surface water system is a possible source for agriculture use that requires sufficient nutrient components

In these tests, the addition of disaggregated CaCO3 to the brine/SI mixture was accompanied by a rise in the pH and a commensurate precipitation of a DETPMP_Ca complex.
