I am very interested in this, and I have also consulted relevant materials to learn more about drinking water. At the weekend, my classmates and I went to Hunan Environmental Monitoring Center Station, visited the State Key Laboratory of Heavy Metal Pollution Detection of Environmental Protection, listened to the professional explanation of the harm of pollutants to drinking water, and observed the detection of water samples by professional technicians.
One weekend afternoon, I rushed to Hunan Library to attend a forum lecture with the theme of "Water Security in China". Just arrived at the scene, the chairman of Changsha Shuguang Environmental Protection Public Welfare Development Center praised me and said, "Liang, you are the youngest netizen to participate in this forum. Welcome to join our volunteer team. "
"You are the youngest reporter to interview this forum! Wait, you have to ask wonderful questions! " A media reporter saw my little reporter's interview card hanging on his chest and smiled and encouraged me.
At the forum, Aunt Liu Shu first introduced their volunteer team's investigation of drinking water in Changsha, Zhuzhou and Xiangtan. Volunteers worked tirelessly to collect water samples in remote villages and voluntarily tested the water quality.
Then, Dr. Lan Weiguang, an adjunct professor at the National University of Singapore, who came here travel-stained, gave everyone a vivid water safety lesson with his own research and entrepreneurship experience and Singapore's water safety story.
Dr. Lan Weiguang said humorously: "Most of the water pollution is neglected. At present, the pollution of drinking water in China mainly comes from three aspects: first, industrial pollution; Second, agricultural and aquaculture pollution, pesticides and other organic substances and waterworks chlorination will produce carcinogens; Third, garbage pollution, such as plasticizers generated by plastic garbage flowing into water bodies, will remain in tap water. "
He told us that one-third of the drinking water in Singapore comes from circulating water, and even the water for flushing toilets can become qualified drinking water after being treated.
"Can I drink water after flushing the toilet?" Everyone is very interested in this.
