The Analysis Of The Mineral Water Quality Of Jinan

OBJECTIVE:Jinan has always enjoyed its laudatory title Spring City. Different to other springs, spring water in Jinan is from the southern mountains in an underground limestone layer, and thus is named as the museum of natural spring water. Furthermore, the spring water is rich in minerals, which is beneficial to immunity enhancement, disease prevention, and longevity. In this study, we collected the water samples of the four major springs, detected the minerals quality, and compared to those of Shan Country spring.Methods1. Water samplingWater samples were collected from Spouting Spring, Black Tiger Spring, Pearl Spring, and Five Dragon Pool of Jinan, and spring water of Shan Country.2. Sampling methodUse the PE plastic bucket to collect water samples when the spring water is spouting from the mouth of the spring. If the spouting spring water can not been collected from the mouth of the spring, put the PE plastic bucket under 0.3-0.5 meters of the water table. Collect two duplicate samples using the PE plastic buckets at every sampling site. Put the cap back on the bucket immediately, and give to the laboratory after attaching the label.3. Examination methodAccording to GB/T8538-2008 "Test methods for drinking natural mineral water",we analysis 16 items as PH,iron,manganese,copper,potassium,sodium,calcium,magnesium,fluoride,bicarbonate,lithium,strontium,zinc,iodide,metasilicic acid,selenium of the water sampling.4. Testing standards1. GB/T8538-2008 "Test methods for drinking natural mineral water" 2. GB5749-2006 "Drinking water health standards"ResultsA total of 16 minerals were detected, which include the GB/T8537-2008 "potable natural mineral water" limit indicators:lithium, strontium, zinc, iodide, metasilicic acid, and selenium, and other mineral projects:PH value, iron, manganese, copper, potassium, sodium, calcium, magnesium, fluoride, bicarbonate. According to GB/T8537-2008 "drinking natural mineral water", at least one of the indicators (lithium, strontium, zinc, iodide, metasilicic acid, selenium, free carbon dioxide, total dissolved solids) should be in line with the standards. (Tablel).The contents of lithium and strontium in the water of the four Jinan springs are all in line with GB/T8537-2008 "Drinking natural mineral water" standard, and the contents of lithium and strontium in Shan Country spring were also in line with the above standard, and other items were consistent with standard. The water of the four Jinan springs and Shan Country spring both meet the standard of the natural mineral water.ConclusionsThe water of the four Jinan springs and Shan Country spring have not yet affected by pollution, are both high quality natural mineral water, and contain many minerals to the required, especially strontiuium selenium are rich in content. Results show the water sample of the Shan Country spring contents more beneficial minerals than the water sample of the four Jinan springs, the mineral water of the Shan Country spring is more conducive to promote human health. The main features and creative points of this thesis are as follows:1. Collect the water samples of the four major springs, detected the minerals quality, and compared to those of Shan Country spring, from the analysis of these indicators acquire the mineral contents of the water of the four Jinan springs and Shan Country spring.2. From comparing the mineral contents of the water of the four Jinan springs to those of Shan Country spring, and from the proportion of longevity in Shan Country is higher than that in Jinan, prove the mineral water of Shan Country in promoting human health is better than that of the four major springs.
