These ions have little or no short-term effects, but toxic ions (lead arsenic, cadmium, nitrate, and others) may also be dissolved in the water. Even the best water purification systems on the market require monitoring for TDS to ensure the filters and membranes are effectively r...
Load reductions of 40% required a range of 8-50 years of data depending on analyte, while FWMC reductions of 40% required 3-10 years of total phosphorus (TP) data, 5-25 years for soluble reactive phosphorus (SRP), and 2-6 years for nitrate (NO 3). We examined relationships among ...
Since the mid 1990?s nitrate concentrations in some of the supply wells are above the Maximum Allowable Concentration (MAC) of 10mg-N/L. The source ... Haslauer,P Claus - 《Spectrochimica Acta Part A Molecular & Biomolecular Spectroscopy》 被引量: 18发表: 2005年 [Hygienic basis for the ...
Wintering of dairy cows on high yielding forage crops is a key contributor towards total farm nitrate leaching loses. High stocking density's, and subsequent excretion of nitrogen- loaded urine, onto bare, saturated soils results in high nitrate leaching rates. Incorporation of standoff facilities ...
