B) 2, 4 and 5 only
C) 1, 3 and 5 only
D) 1, 2, 3, 4 and 5
Ans: C). 1, 3 and 5 only
Explaination :
- Drinking water in some parts of India have contaminants like Arsenic and Fluoride.
- The sources of arsenic include run off from orchards, metal smelting among others.
- The sources of Fluoride are erosion of natural deposits, discharge from fertilizers and Aluminium factories.
- The drinking water in some parts of India also contains traces of Uranium. The main source of the Uranium contamination is natural, but human factors such as groundwater-table decline and Nitrate pollution may exacerbate this problem.
- Some naturally occurring elements in drinking water are Lead, Arsenic, Mercury, Radium, Chloride, Iron and Copper compounds. Most of these are not harmful when consumed in small quantities. But when the consumption is higher than the prescribed amount, it could be harmful and sometimes even fatal.
- Water in India is contaminated with salinity, Arsenic, Fluoride, Iron, Nitrate, and heavy metals.
- Sorbitol is a sugar alcohol found in fruits and plants with diuretic, laxative and cathartic property.
- Unabsorbed Sorbitol retains water in the large intestine through osmotic pressure, thereby stimulating peristalsis of the intestine and exerting its diuretic, laxative and cathartic effect.
- Formaldehyde is a colourless, strong-smelling gas used in making building materials and many household products. Formaldehyde quickly broken down in the air – generally within hours. It dissolves easily in water, but does not last long there, either.
