Description Zinc occurs in small amounts in almost all igneous rocks. Zinc imparts an undesirable astringent taste to water. Tests indicate that 5% of a population could distinguish between zinc-free water and water containing zinc at a level of 4mg/litre (as zinc sulfate)*. Water containing zinc at concentrations above the range 3–5 mg/litre also tends to appear opalescent and develops a greasy film when boiled and has an undesirable astringent taste. In natural surface waters, the concentration of zinc is usually below 10 μg/litre, and in ground waters, 10–40 μg/litre*. In tapwater, the zinc concentration can be much higher as a result of the leaching of zinc from piping and fittings*. Drinking-water usually makes a negligible contribution to zinc intake unless high concentrations of zinc occur as a result of corrosion of pipings and fittings. Under certain circumstances, tapwater can provide up to 10% of the daily intake*. (*source: zinc in Drinking Water, Background document for development of WHO Guidelines for Drinking Water Quality) Benefits of testing for Zinc: A certain amount of zinc is required, but an excessive amount can lead to zinc poisoning. Symptoms can include fever, nausea, vomiting, stomach cramps and diarrhoea, sometimes accompanied by bleeding and abdominal cramps. Increased daily dosage above the recommended dietary allowance has also resulted in copper deficiencies and the impairment of various immune responses. A daily dietary requirement of zinc of 0.3mg/kg of body weight and a provisional maximum tolerable daily intake (PMTDI) of 1.0 mg/kg of body weight (35) has been proposed. The daily requirement for adult humans is 15–22 mg/day*. Ideal to test zinc ions in a reasonable clear solution. It is a self-test which can be done in the comfort of the home and it gives results in minutes. The colour result of the solution after the test can be measured against a calibrated colour strip provided on the box containing the kit. The kit is therefore a very simple, easy to use, fast and economical check for the presence of Zinc in the body, food, water, or anything in the environment. For the body, use first morning urine. For other materials prepare the specimen solution with the material. The procedure to prepare this solution can be obtained by contacting us. This multi-purpose test kit tests not only the presence or absence of zinc but also gives an indication of the amount in parts per million (ppm) in water, the body and a wide range of materials. Suitable for: urine, water; to test the substances which are not in solution, preparation can be made to convert them into solution for testing, this includes dust, dirt, paint, rice, milk, food, dishes, glasses It is recommended to use saliva only if the user wishes to test for manganese or other metals that may be leaking from any amalgam dental fillings. Otherwise, to test for heavy metals in the body, the user should use urine as the sample solution to be tested.
