According to experts' statistics, according to the calculation that each person discharges 0.5 kg of feces and 1.5 kg of urine every day, at least 3000 tons of feces and urine are scattered on both sides of the railway every day in China. Such a huge amount of feces, because of the speeding of the train, was torn into endless fine fog particles by the wheels and powerful airflow, which spread around with the airflow. Hookworms, roundworms, tapeworms, schistosomiasis ... and hepatitis. Especially human parasitic diseases, most of them are related to feces, and most parasitic diseases are spread through feces.
At present, there are 40,000 trains in China, and each train has at least 30 toilets. There are about1.20 thousand toilets in China that need to be rebuilt urgently.
Recently, the relevant media reported a statistical data, which made the problem of direct discharge of train feces attract widespread attention again.
Song Fuxiang, an associate researcher at Jilin Beihua University, said in a letter to Pan Yue, deputy director of the State Environmental Protection Administration, that medical research shows that human and animal excreta are the transmission hosts of infectious diseases, common diseases, frequently-occurring diseases, parasitic diseases, occupational diseases and other diseases. In particular, under the action of rapid air pressure, human excrement is decomposed into extremely fine gas mist particles by high-speed trains, which are dispersed in the air and spread out, making it impossible to prevent.
According to reports, the total mileage of China Railway has reached more than 70,000 kilometers, carrying 65.438+005 million passengers every year; However, the train toilets in China are still straight. "According to the calculation that each person discharges 0.5 kg of feces and 1.5 kg of urine every day, at least 3,000 tons of feces and urine are scattered on both sides of the railway every day." During the holidays, the excrement discharged outside the train compartment has exceeded 1 10,000 tons every day.
