Sometimes mercury is released through emissions from manufacturing, use, or disposal activities. Mercury in the air eventually settles into water or onto land where it can be washed into water. High mercury exposure results in permanent nervous system and kidney damage. Mercury is commonly found in thermometers, manometers, barometers, gauges, valves, switched, batteries and high-intensity discharge lamps. It is also used in amalgams for dentistry, preservatives, heat transfer technology, pigments, catalysts and lubricating oils. Due to the hazards caused by high levels of mercury, we offer mercury testing in products to ensure health safety.
