MCQ-> In the following questions, you have a brief passage with 5 questions. Read the passage carefully and choose the best answer to each question out of the four alternatives.The problem of water pollution by pesticides can be understood only in context, as part of the whole to which it belongs – the pollution of the total environment of mankind. The pollution entering our waterways comes from many sources, radioactive wastes from reactors, laboratories, and hospitals; fallout from nuclear explosions; doemstic wastes from cities and towns; chemical wastes from factories. To these is added a new kid of fallout – the chemcial sprays applied to crop lands and gardens, forests and fields. Many of the chemical agents in this alarming melange initiate and augment the harmful effects of radiation, and within the groups of chemicals themselves there are sinister and little – understood interactions, transformations, and summations of effect. Ever since the chemists began to manufacture substances that nature never invented, the problem of water purification have become complex and the danger to users of water has increased. As we have seen, the production of these synthetic chemicals in large volume began in the 1940’s. It has now reached such proportion that an appalling deluge of chemical pollution is daily poured into the nation’s waterways. When inextricably mixed with domestic and other wastes discharged into the same water, these chemicals sometiems defy detection by the methods in ordinary use by purification plants. Most of them are so complex that they cannot be identified. In rivers, a really incredible variety of pollutants combine to produce deposits that sanitary engineers can only despairingly refer to as “gunk”.All the following words mean ‘chemicals’ except

MCQ-> Read the following passage to answer the given questions based on it. Some words/ phrases are printed in ‘’bold’’ to help you locate them while answering some of the questions.The e-waste (Management of Handling) Rules, 2011 notified by the Ministry of Environment and Forests, have the potential to turn a growing problem into a developmental opportunity. With almost half-a-year to go before the rules take effect, there is enough time to create necessary infrastructure for collection, dismantling, and recycling of electronic waste. The focus must be on sincere and efficient implementation.Only decisive action can reduce the pollution and health costs associated with India’s hazardous waste recycling industry. If India can achieve a transformation, it will be creating a whole new employment sector that provides good wages and working conditions for tens of thousands. The legacy response of the States to even the basic law on urban waste , the Municipal Solid Wastes (Management and Handling) Rules, has been one of the indifference many cities continue to simply burn the garbage or dump it in lakes. With the emphasis now on segregation of waste at source and recovery of materials, it should be feasible to implement ‘’both sets of rules’’ efficiently. A welcome feature of the new e-waste rule is emphasis on extended producer responsibility. In, other words, producers must take responsibility for the disposal of end-of-life products. For this provision to work, they must ensure that consumers who sell scrap get some form of financial incentive. The e-waste rules, which derive from those pertaining to hazardous waste, are scheduled to come into force on May 1, 2012. Sounds as they are, the task of scientifically disposing a few hundred, thousand tonnes of trash electronics annually depends heavily on a system of oversight by State Pollution Control Boards (PCBs). Unfortunately, most PCBs remain unaccountable and often lack the resources for active enforcement. It must be pointed out that, although agencies handling e-waste must obtain environmental ‘’clearances’’ and be authorised and registered by the PCBs even under the Hazardous Wastes (Management, Handling and Transboundary Movements) Rules, 2008, there has been little practical impact. Over 95 per cent of electronic waste is collected and recycled by the informal sector. The way forward is for the PCBs to be made accountable for enforcement of the e-waste rules, and the levy of penalties under environmental laws. Clearly, the first order priority is to create a system that will absorb the 80000-strong workforce in the informal sector into the proposed scheme for scientific recycling. Facilities must be created to upgrade the skills of these workers through training and their occupational health must be ensured. Recycling of e-waste is one of the biggest challenges today. In such a time, when globalization and information technology are growing at a pace which could only be imagined few years back, e-waste and its hazards have become more prominent over a period of time and should be given immediate attention.What according to the passage is important now for e-waste management?
