Lead & zinc waste tank breaks down in Cao Bang causes

The waste sludge may not only contains lead, but other heavy metals as well.

VietNamNet Bridge - The waste sludge may not only contains lead, but other heavy metals as well. Scientists have warned the problem would be very serious if the sludge reaches the environment. The lead & zinc waste tank in Pac Mieu Town of Bao Lam district in Cao Bang province unexpectedly broke down on January 5, releasing hundreds of thousands of cubic meters of water and waste sludge into the Gam River, having seriously polluted the river. Vu Ngoc Luu, chair of Bao Lam district, said late last week that the damages caused by the incident remain unclear. VnExpress quoting Pham Khang from the Nature & Environment Protection Association as saying that there is not only lead, but other heavy metals as well in the waste sludge, therefore, it would be very dangerous if the sludge is widely spread out in the environment. If the lead concentration found in the sludge is not high, people should scoop up the soil and throw it away. They should also be warned against using water … [Read more...]

Vietnamese shoppers swear by food test kits

A Vietnamese-styled market.

For more than two months now, Hanoian housewife Nguyen Thanh Thuy says a Russian-made food test kit has been an inseparable companion on shopping trips to local markets and supermarkets. Thuy said that the test kit, a device as small as a mobile phone with a pointed metal stick, helped her feel more confident shopping for toxic-free food materials, just after 15 to 20 seconds of testing. "With concerns about food hygiene and safety, I bought this device for VND4.5 million (US$200) through a website that said it can detect the toxic residues on vegetable, fruit, meat and fish. I have been using it to its utmost since then," she said. Thuy said that many circles of housewives in Ha Noi have been whispering about the test kits, many of whom are concerned about pesticides and food practices. Two popular options available from Russia have Vietnamese language settings and can detect toxicity in more than 60 types of food. Using the device is simple and only requires inserting a metal … [Read more...]

Professor invents water filtration technology

1701684-20150703060819-scitech-envir-water

VietNamNet Bridge - Associate professor Tran Hong Con from the Hanoi University of Natural Sciences is the creator of the Hanoi dirty-water map, a unique water filtration technology and the inventor of many other water-related research works. In 1996, Con was hired by his school to test water samples from a suburb in Hanoi. More than 10 out of 30 water samples were found having arsenic concentration much higher than the permitted level. He then decided to learn more about the underground water situation in Hanoi. Later, Con created a water map of Hanoi, showing the areas contaminated with arsenic. These included eight water plants in the inner city and self-dug water wells in the suburbs. Up to 30 percent of surveyed wells were found having arsenic concentration at over 0.05 mg/l, while 50 percent were over the permitted level of 0.01 mg/l. Con realized that people only filtered underground water manually to eliminate iron, while the measures they applied could not eliminate … [Read more...]

Toxins found in Hanoi tap water

People in outside provinces and cities have long envied Hanoians for the clean running water the capital city enjoys. The facts, however, suggest their feelings are misplaced.

VietNamNet Bridge - The cost of running water in Hanoi has been increasing sharply, while the quality of that water remains stubbornly low -toxin concentrations are far higher than permitted levels, while pipeline breaks are a regular occurrence. A series of water treatment plants have been built in recent years to satisfy the rapidly growing demand in the city. However, the plants, with 100 year-old filtration technology, do not help improve the water quality. Hanoians live in fear that they may one day suffer deadly diseases because of the unsafe water. … [Read more...]

Ha Noi tap water poses health risks

HA NOI (VNS) — Tap water samples collected from different plants in the capital city fail to meet the Health Ministry's hygiene standards and pose a public health hazard, according to the Ha Noi Preventive Medicine Centre. The centre says tests on samples taken from different water plants in Ha Noi since January this year show excessive levels of minerals and chemicals that can have serious consequences for residents. A sample from the Phap Van Water Plant showed the Permanganate index, which can cause dermatitis, exceeding the regulated level by 1.6 times, while that collected from the Ha Dong Water Plant exceeded the allowed level by 0.4-0.8 times. … [Read more...]

HA NOI (VNS)— A representative of Ha Noi Water Company has denied claims that water supplied by several water companies in the city has been contaminated with arsenic, a toxic chemical linked to skin cancer. Nguyen Nhu Hai, General Director of the Ha Noi Water Company, said there was no evidence to substantiate the allegations. "We examine the quality of water regularly and figures on the chemicals in the water are checked every day in all of these facilities. The level of arsenic is tested every six months," said Hai. "Thus, it can be affirmed that water supplied by branches managed by Ha Noi Water Company meets the Ministry of Health's requirements. People do not have to be worried about using the water," he added. Hai also said that water filters used improperly could filter out helpful minerals and affect the mineral compilation of the water. He made the statement after a study carried out last year by a group of Vietnamese scientists with researchers from Columbia … [Read more...]

farmers-told-to-use-new-technologies-to-treat-polluted-water-in-flood-areas-1248978-20131105113117-envir

VietNamNet Bridge - A lot of advanced technologies have been invented to help sterilize polluted water. However, Vietnamese farmers in the flood stricken areas still cannot approach the technologies. According to Dr. Tran Hong Con from the Hanoi University for Natural Sciences, a member of the Hanoi National University, in floods, sanitation works, sewers, fields and livestock farms get submerged in water, while the waste from different sources drifts with the current, which makes the water seriously polluted. Therefore, treating the polluted water to get clean water for daily use is the urgent task people have to do after the floods. In order to have clean water for daily use in case the floods strike down, people have been sterilizing polluted water with alum and Chloramine B, the method they have been applying over the last many years. At first, people pour alum into water to clean it (the sediments will settle down). After that the cleaned water will be filtered through … [Read more...]

warnings-danger-people-water-1-334400-100x100

The water monitoring results show that the underground water resources have been decreasing in many places. Meanwhile, the underground water has also got infected with ammonium and arsenic, which is a big threat to local residents who cannot access the national water supply system. According to Dr Nguyen Thi Ha from the Center of Water Resource Monitoring and Forecasting under the Ministry of Natural Resources and the Environment (MONRE), in the Northern Delta, the water levels at some monitored places, including Mai Dich, Cau Giay in Hanoi, have decreased nearly to the allowed limits. In some other areas of Hai Hau, Truc Ninh, Nam Dinh, Quynh Phu and Thai Binh, the decreased water levels are still within the safety line. However, scientists have warned that the aquifer has complicated hydrogeological conditions; therefore, it is necessary to apply necessary measures to prevent the saltwater intrusion caused by the water exploitation.

Former math majors – where are they now?

Mathematicians meet on December 20

VietNamNet Bridge - Nearly all the talented students who finished math major classes at high schools for the gifted have succeeded in their lives and business. The most successful mathematics talents (about 20-30 people) were born in the 1950s and later, after math majoring classes for the gifted were established, according to Prof Nguyen Huu Viet Hung from the Hanoi University of Natural Sciences. However, Hung said, this does not lead to a conclusion that the system of general schools for the gifted in math are needed to train successful mathematicians. Hung, a well-known mathematician, noted that the majority of successful mathematicians in the world did not come from math majoring classes for the gifted. They are citizens of countries with developed sciences such as the US, UK, France, Germany, Italy and Japan, where math majoring classes do not exist. "As they are the best, in Vietnam will surely succeed with their math studies or succeed in other fields, no matter if they … [Read more...]

Are schools for the gifted really needed?

1744529-20150911071918-edu-gifted

VietNamNet Bridge - Schools for the gifted are defined as the incubators which help grow up talented students into excellent scientists and professionals. However, in Vietnam, many students go to the schools just because they want to have better learning conditions which help them pass the entrance exams to universities. The Ministry of Education and Training (MOET) once tried to develop the system of general schools for the gifted throughout the country. However, it recently decided that there won’t be secondary schools for the gifted anymore. Analysts make common cause with the ministry, saying that the schools will put too hard pressure on small children. However, the ministry’s decision still cannot put an end to the prolonged debate about whether schools for the gifted are necessary in Vietnam. The first class for the gifted, majoring in math was established in Vietnam in 1965, put under the Hanoi University and managed by renowned scientists and educators such … [Read more...]
