Poto keindahan dunia dari mata lensa kamera - June 10, 2015 at 01:54AM


Photo by @GerdLudwig. The surface of the large open-air Ivanhoe Reservoir in Los Angeles is completely covered with over three million black plastic balls, which help deflect UV rays. In 2007, high levels of bromate - a carcinogen formed when bromide and chlorine react with sunlight - were found in its water which prompted officials to look for affordable ways of shading the reservoir. A biologist suggested so-called “bird-balls”, commonly used by airports to prevent birds from congregating in wet areas alongside runways. The balls, which cost 40 cents each, are made of polyethylene, with carbon coating. The city recently continued with the program, covering the LA Reservoir as well. @thephotosociety @natgeocreative @theimagereview #Ivanhoe #reservoir #LosAngeles #California #preservation #chemicals #boat #carcinogen #environment #bromate
