Scientists at the University of Stockholm, Sweden, have discovered an aquatic moss that purifies water containing arsenic into a water that can be safely consumed.
Arsenic is a natural element that is widely stored in the local shell (soil, minerals). It may enter the air by the wind, or it may enter the water by turbulence and leaching. Human exposure to arsenic from food, water, air or burning fumes can lead to nausea and vomiting, decreased white blood cell and red blood cell production, abnormal heart rhythms, vascular damage, and "needle pain" at the end of the hands and feet.
According to a recent study published by the University of Stockholm in Sweden in the journal Environmental Pollution, scientists have discovered a species of aquatic moss known as "Warnstorfia fluitans" that grows in northern Sweden due to mining operations and is contaminated with toxic arsenic. Near the wetlands, the arsenic content in the water can be reduced to a drinkable level.
Kiruna, Sweden's northernmost city (Swedish: Kiruna) used to be a mining town. Iron ore was refining the pillar industry in the region. During World War II, a large number of iron ore were transported by train from the north of Sweden to the east coast. Support the German war. Because of the large amount of mining, the area is not only heavily fragmented, but even the wetlands and drinking water sources used to grow crops are often contaminated with arsenic, a common waste in the mining industry.
But the world's law is always a thing. The aquatic moss called Warnstorfia fluitans grows lush in northern Sweden. It is found in the laboratory by researchers at Stockholm University that these mosses can quickly absorb arsenic and eliminate up to 82 in one hour. % toxins (but none of them have been tested on site). If further experiments are carried out, the quality of the water added to the other mixture will slow down the moss filtration process, which is closer to the actual situation.

"How much arsenic we end up eating depends on how much arsenic we eat and how and where we plant it." Maria Greger, associate professor of the Department of Ecology and Plant Sciences at Stockholm University, said that based on this research, locals will This environmentally friendly approach can be used to purify water, such as the cultivation of Warnstorfia fluitans moss in streams and other high-arsenic waterways.
As for the moss, how does the moss survive after eating arsenic? The researchers found that most of the toxins bind to mossy tissue and become harmless, and that few organic organisms eat wetland moss. This mechanism may have the opportunity to help break the food chain cycle of arsenic poisoning. (TechNews)
What is Indoor PTZ Camera
PTZ: In the security monitoring application, it is the abbreviation of Pan/Tilt/Zoom, representing the pan tilt omnidirectional (up and down, left and right) movement, lens zoom and zoom control.
PTZ: In the security monitoring application, it is the abbreviation of Pan/Tilt/Zoom, representing the pan tilt omnidirectional (up and down, left and right) movement, lens zoom and zoom control.Automatic tracking is divided into three types: one is through embedded video encoder, also known as intelligent visual server; the other is PC software; the other is to directly write the tracking algorithm to DSP chip, and then design the DSP chip as a hardware circuit on the high-speed ball motherboard, and the high-speed ball is directly read. Among the three types, the third type is used most in the current market.
The intelligent vision PTZ automatic tracking and monitoring system consists of an intelligent vision server (responsible for intelligent analysis and command) and a high-speed spherical camera (responsible for tracking targets). The automatic PTZ intelligent tracking function enables the camera to automatically PTZ drive its own PTZ and zoom lens, and automatically control the PTZ camera to rotate the PTZ in all directions and zoom the lens, and perform visual oriented automatic tracking for the locked moving target, so as to ensure that the tracking target continues to appear in the center of the lens with a close-up image, so that the security personnel can see the information more clearly, It can also be used for obtaining evidence afterwards. The automatic PTZ tracking module makes up for the narrow field of vision of fixed camera monitoring, which is an essential function of a perfect security monitoring system.
The intelligent vision PTZ automatic tracking and monitoring system has the target analysis function, and is equipped with a high-resolution camera, a large magnification optical zoom lens and a high speed PTZ, which can automatically capture suspicious targets quickly and accurately. By setting the preset position intelligent vision PTZ automatic tracking monitoring system, the preset position scanning, automatic cruise and other functions can be realized, and many special requirements of intelligent monitoring can also be realized. In addition, the intelligent vision PTZ automatic tracking and monitoring system also has the advantages of beautiful appearance and strong concealment, so it is very suitable for public security intelligent monitoring applications in airports, squares, rail transit, villas, government administrative units, military regions, museums and other types of places.
The automatic PTZ tracking and monitoring system integrates optics, electronics, machinery, information processing and network, and is composed of camera, power transmission, motion control device, image analysis, recognition, compression and communication based on high-speed parallel processing. It has the functions of video camera, position control, orientation and lens preset, moving object detection, recognition and tracking, flame and smoke detection and alarm, etc. It can be widely used in buildings, banks, airports, stations, customs, transportation, power, factories and mining enterprises and other security monitoring occasions.
