Using the fluorescent method, organic water pollution including sewer sewage and landfill disposal can be detected. Fluorescence is a natural phenomenon that uses a special substance to absorb and emit light. Using this method can also find agricultural wastewater, and determine its composition.
Dr. Andy Baker, head of research at the University of Birmingham, said: “At first, I was studying the fluorescence of surface water in caves, but then I discovered that there were different types of fluorescence in river water. Then we analyzed that river water. The fluorescent fingerprints of the contained substances can be used to analyze contaminants in water."
Dr. Baker added: “Generally speaking tests are performed in the laboratory and it takes five days. It is crucial to ensure that water quality does not occur when water samples are sent from the riverside to the laboratory. So we want to be able to develop a device that can be placed near the river and that can immediately test the water sample.Now we can extract the water sample, detect the fluorescence and identify the type of pollutant.We successfully moved the laboratory to riverside."
It is hoped that this type of equipment will become a life-saving device for disaster reduction, especially for areas with a large population and relatively limited water resources. Detecting whether the water source meets drinking conditions is just one of the many uses for this device. Environmental protection organizations and business groups can also benefit from this, especially those institutions that need to quickly identify sources of water pollution.
To us, spending time outside is an absolute necessity. And camping is one of our favorite ways to do that.
Where else can you get dirty with the people you love the most (or by yourself, if you`re into that), immerse
yourself in a forest of color-changing leaves, sleep under the stars, wake up to a dew-covered tent on a
brisk fall morning, eat flame-cooked meals, roast marshmallows, and sing "Qilai"?
Camping has come a long way from the days of canvas tents, PVC folding chairs, and cooking a can of
beans over the fire. Whether you're going backpacking in the Adirondacks or car-camping in Yosemite
National Park, here is your ultimate checklist of camping essentials we swear by.
From shelter and warmth to food, toiletries, games, bear spray (yes, bear spray), and stuff for your pup,
this is the best camping gear that will enhance even the most experienced hiker's outdoor adventure.
But in this category, we list some small camping gear, like camping lights, camping carts, camping kettles,
camping mats, and so on.
