READING COMPREHENSION

 

The last few years have seen a debate on the toxic nature of lead-acid batteries, because of the possible harm lead can cause to the environment. However, responsible battery manufacturing companies in conjunction with the Indian

government are determined to combat the indiscriminate disposal of batteries, to safely smelt and recycle them and minimize their harmful effects on environment and health. Indian law demands, that spent batteries be recycled and reach authorized smelters. It is alarming to note that nearly 50 per cent of the Indian battery market is catered to by re-builders that reclaim lead through unsafe processes, and source their lead illegally. This could mean that about four million batteries in India are still disposed in an unsafe manner, putting our environment and our lives at great risk.

 

Is lead really that bad? Lead is one of the most pervasive and toxic of all environmental contaminants. Both acute and chronic exposure to the metal have been shown to cause metabolic, neurological and neuro-psychological disorders. The physiological effects of lead are many, lead interferes with haemoglobin production, resulting in anaemia. Children are at a greater risk of lead poisoning than adults, because they absorb about 50 per cent of lead compared to 10 per cent in adults.

 

Potential complications in proper development include decreased intelligence, impaired neurobehavioral development, and growth as well as impaired ability to maintain a steady posture. Higher levels of lead in blood can damage the central nervous system, kidneys and haematopoietic system in children. Children with blood levels of lead greater than 80 ug/ml, can fall into a coma, experience convulsions or even die. High blood levels during pregnancy are correlated with still birth, miscarriage, and central nervous system damage of the foetus.

If lead is so bad, why use it at all? Lead is 100 per cent recyclable and is a by-product of Zinc production. The automotive battery industry is the largest consumer of lead. The lead-acid couple is time tested and has numerous technological and financial advantages. Safe disposal of batteries is the key of safe living and a healthy environment. How can one do one’s bit to prevent pollution from lead?

 

First and foremost, buy batteries made only by manufacturers of repute. Apart from a good product and higher warranty, it will also fetch peace of mind. All manufacturers have battery collection centres. Always ensure the used car battery is properly recycled. So what happens once the battery goes back to the authorized centre? These centres take adequate care in handling the used batteries. The returned batteries are transported to the nearest government of India authorized smelting unit. These authorized smelters are equipped to reclaim lead from these scrap batteries in the most environmentally friendly manner. Lack of consumer awareness about the requirement of proper disposal and compliance of all the stakeholders is the bottleneck in the system.

 

Use the below information to solve questions from 6 to 10.

 

These questions are based on the following information.

Eight-persons–G,H,I,J,K,L,M,and N–are sitting in a row but not necessarily in the same order. Some of them are facing south and the remaining are facing north. No two persons sitting adjacent to each other face south.

 

◝ J sits two places away from H and they both face different directions.

◝ M sits second to the right of G.

◝ The number of persons to the right of M is one less

than the number of persons to the right of K.

◝ K sits to the immediate right of H, who faces the

same direction as I faces.

◝ I sits to the immediate left of N and one of them sits

at an end.

◝ G sits to the left of N, who sits to the left of L.

◝ K and L face the same direction which is different

from the direction which M faces.
