Thanks to industrial revolution, the nature is no more what it originally was. The air no longer remains fresh while dumping of industrial waste in water bodies keep on haunting us. Indiscriminate use of fertilizers and pesticides have already intoxicated the soil. So, there is an immediate need of proper and timely health hazard detection to protects ourselves from various forms of pollutants present in air, water, soil and in immediate microenvironment. Thanks again to the advances in technology, various testing methodologies have been developed to aid in detection of such pollutants, for instance, Lead test kits helps in detecting lead contamination from various lead-based paints, tap water, colorful ceramic dishes, lead-painted toys, soil and airborne lead particles. Anyhow, did you know that lead poisoning may results in limiting a child's ability to learn,as a child's IQ can drop 3 points for every 10 micrograms per deciliter of lead in their blood! Radon, on the other hand is a radioactive gaseous element formed by the disintegration of radium which occurs naturally especially in areas over granite and considered as one of the major causes of lung cancer.No wonder, we have radon test kits too which can test both, radon in gas and radon in water. Similarly, Asbestos, a fibrous amphibole; used for making fireproof articles, inhaling which can cause asbestosis or lung cancer, can also be detected by various asbestos testing kits which are often based on polarized light microscopy (PLM).
