The goal of this study was to assess the phytoremediation potential of transgenic Indian mustard plants. The increase in metal accumulation as a result of these genetic engineering approaches is typically two-to-threefold more metal per plant, which potentially enhances phytoremediation efficiency by the same factor. The significance of this finding is that it is the first to demonstrate an enhanced capability of transgenic plants to phytoextract environmental soil containing a mixture of metals.

This article explores the potential of RFID (radio frequency identification device) for improving the current waste and resource management system in Switzerland. It presents the following three possible options for utilizing RFID tags to support waste management processes:

Toxic effects of chromium on pure culture of Salmonella paratyphi-B and Shigella flexneri isolated from sewage effluent were studied.

THE management of huge and growing quantities of electronic waste may emerge as one of the more important environmental problems of developing countries in the near future.

Toxic water released from several yarn dyeing and processing mills in Belkuchi upazila of Sirajganj district is polluting the local environment, causing untold suffering to thousands of people and posing serious health hazard. Influential people set up the mills in an unplanned way without any treatment plant and drainage system, by managing some unscrupulous officials of the relevant sections, said local residents. Over 100 yarn dyeing and processing mills at different villages including Tamai, Shohagpur, Garamashi, Chala, Chandangati and Mukundagati have no treatment plant and they were set up without permission from the authorities concerned, locals said. Eleven of the mills owned by Aziz Sarker, Hiron Munshi, Labu Shaikh, Anwar Hossain, Badol Khan, Abdul Kader, Hiron Sarker, Babu Salam, Rejaul Karim, Khokon and Abdul Motin at Tamai village are posing most serious threats, they said. Toxic chemicals like sulphuric acid, acetic acid, hydrogen-per oxides, caustic soda, bleaching powder, silicate, glace and colours are used in these mills to treat the thread or cottons. After releasing from the mills, the untreated water is mixed with ponds and marshes in the area and creates serious health hazards. An acute crisis of pure and clean drinking water is prevailing in the area as toxic wastes from the mills are mixed with the under ground water, turning water from the tube-wells yellowish. Many people are being affected with skin diseases, diarrhoea, dysentery, eye infection and nausea due to use of the water. Mukti Khatun, 35, wife of Golam Kibria of Tamai village, said she has been suffering from skin diseases for the last few years. Her seven-year-old child has been affected with gastric disease by drinking the toxic water, she quoted doctors as saying. The toxic water has damaged fertility of hundreds of acres of croplands and fishes of ponds and marshes in the area. Many fruit bearing trees in the area have died while taking of the toxic wastes from drinking the water also caused the death of domestic animals and fowls including cows, goats, ducks, hens, villagers said. Many houses made of corrugated iron sheets in the area became rusty and got damaged within a short time due to the vapour and toxic waste of the mills. The atmosphere in and around of the mills has become seriously dirty and unhygienic, as the water remains stagnant in absence of proper drainage system. Azam Khan, Dulal Mollah, Mohsin Pramanik, Fazlur Rahman and Zamal Uddin of Tamai village said several times they went to Belkuchi upazila Sanitary Inspector Mohammad Ali Jinnah to discuss with him about the ways to get rid of the problem but he ignored them. They also submitted petitions to the deputy commissioner in Sirajganj, UNO in Belkuchi, director of Department of Environment (DoE) in Bogra, Rab and Army to take initiative for saving the environment, but to no effect. Even a case was lodged with Belkuchi Police Station in this connection against the mills owners. The complainants said Director of DoE Bogra office Mosharraf Hossain misbehaved with them and threatened to get them arrested by police, if they further demand proper action against the mills owners. Contacted over phone three times, Mosharraf Hossain declined to make any comment saying that there was network problem and he was busy. Aziz Sarker, owner of SI process mill, said, no one of authorities concerned ever asked him to stop the mill or set up a treatment plant since its establishment. Belkuchi Upazila Nirbahi Officer Khairul Alam Sheikh said he has written to the authorities concerned suggesting setting up of necessary treatment plants in the area.

The objective of these guidelines is to provide guidance for identification of various sources of waste electrical and electronic equipments (e-waste) and prescribed procedures for handling e-waste in an environmentally sound manner. These Guidelines are reference document for the management, handling and disposal of e-wastes.

A seven year remediation program for the hazardous waste treatment site situated at the Ramat Hovav Industrial Zone in Israel begins.

The electrical and electronic waste (e-waste) is one of the fastest growing waste streams in the world. The increasing

Bangalore figures prominently in the world map for its contribution in Information Technology (IT). This phenomental growth over the past decade, has given rise to the generation of lot of electronic waste. E-waste thus generated contains many recoverable metals and non metals along with hazardous wastes and their improper disposal may cause environmental problems.

Aqueous wastes containing thiocyanate (SCN) are frequently encountered from variety of industrial processes. If improperly managed, these wastes can cause reversible or irreversible impact on the soil and water environment. In the process of developing a microbial technology for the SCN removal from aqueous waste, heterotrophic bacterial consortium's capable of degrading the SCN compound were isolated by an enrichment culture technique from activated sludge and garden soil.
