Overall project
Heavy metal contaminants in water pose serious health problems; the lungs, liver, kidneys, blood, digestive system, and the nervous system are all affected by contamination. The Agency for Toxic Substances and Disease registry released a Priority List of Hazardous Substances (ASTDR). Heavy metals accounted for almost half of the top 10 substances; therefore, we have constructed a set of sensors that detects heavy metal contaminants in water. Our sensors provide an inexpensive, simple, and visual test for Arsenic (the number one substance from ASTDR’s list), Lead (number two), and Cadmium (number seven). One sensor paired a promoter responsive to both Cadmium and Arsenic with GFP as a reporter. Another was created for the detection of Lead and a third sensor was specific to cadmium. Use of the detector could potentially save lives around the world through early detection of the contamination.
The kit will include all necessary components for running the test and then decontaminating the resulting growth to prevent release of the engineered bacteria into the environment. We will include a very simple mechanism for killing or denaturing the bacteria in our detector kit – bleach. Bleach is highly effective at killing bacteria and is readily available to the average person.
