Heavy metals testing can detect metals that are harmful in both small and large amounts, such as lead, mercury, arsenic, and cadmium which if undetected can lead to heavy metals in food products. If consumed, these chemicals can lead to a range of health problems, increasing the risk of a number of diseases and damaging vital organs, such as the kidneys, liver, and brain. Heavy metal detection methods in water and soil are the only reliable ways to determine whether there are dangerous levels of heavy metals present.

PCBs are a group of man-made organic chemicals consisting of carbon, hydrogen, and chlorine atoms. The number of chlorine atoms and their location in a PCB molecule determines many of its physical and chemical properties. PCBs have no known taste or smell, and range in consistency from an oil to a waxy solid.

Dioxins are a group of toxic chemical compounds these materials are not created intentionally but are produced as a result of human activities like the backyard burning of trash and the production of a few herbicides. Dioxins are highly toxic and can cause cancer, reproductive and developmental problems, damage to the immune system, and can interfere with hormones.

Fertilizers are a combination of potentially harmful chemicals which can be absorbed by plants and possibly enter the food chain through cereals, vegetables and can even make its way through our drinking water. Chemical fertilizers can cause problems with the heavy metals that can be found in it. These include Lead, Mercury, Cadmium, and Uranium, which can have a negative impact on the kidneys, liver, and lungs. These heavy metals are also associated with other human health hazards.
