Teraethyl Lead and Biopurification

Teraethyl Lead (TEL)-
· TEL is an organolead compound(chemical compounds containing a chemical bond between carbon and lead). It is a toxic colorless synthetically made oily liquid and was mixed with leaded petrol in 1920s as a patented octane booster/ anti-knocking agent that allowed engine compression to be raised substantially, which helped in increasing vehicle performance or fuel economy.
· But its negative impact related to neurotoxicity (lead poisoning), damaging effect on catalytic converters and were main cause for spark plug fouling which lead to start of its phase out in 1970s
· Currently, it is still used as an additive in some grades of aviation gasoline and in some developing countries
Biopurification:
· It is the natural process of exclusion of harmful elements from human body (to maintain optimum level) that has evolved through millions of years of human evolution.
· For example: Calcium and Barium are found in tandem. While calcium is useful for us, barium is poisonous. Our body has evolved in such a way that it produces protein that effectively absorbs calcium while being almost ineffective for Barium
· According to concept of biopurification, natural concentration of harmful elements in human body should be far lower than toxic levels
· This concept of biopurification was first conceptualized by Clair patterson, a geochemist in trying to nullify Robert Kehoe's (medical scientist) claim for higher toxic natural level of lead in human body.
The recent publication of Chinese defense papers clear the air on a variety of issues, including the direction the Chinese military is planning to take. It sets out a broad framework within which expansion will take place, with a few defined focus areas. These areas are forays into high seas and overseas interests-including energy security.
A case for an Indian white paper on foreign policy may be built as follows:
1. A white paper lays down an integrated approach to foreign policy, with all variables being put in the balance. It can serve as a document which translates into actions. A foreign policy will define actions, and not actions foreign policy.
2. A piecemeal approach to foreign policy may be avoided. Rather than shaping the very basics of a particular policy over years in joint communiques and conferences (as happened with Look East Policy, now Act East policy after it remained stale for long); it is desirable to put in place a comprehensive plan.
3. A white paper also assure predictability and continuity in foreign policy. In the international arena, it is important to be consistent. The recent breakdown of talks with Pakistan over Hurriyat leaders is an example of break in foreign policy. (Or include Indian vote on Sri Lanka in UNHRC)
4. A white paper will help cover all aspects which have hitherto been on the backburner or neglected: for example, India's policy on the middle east. Rather than ad-hocism, a well thought out approach is required.
5. Lastly, a white paper will assimilate the tenets of Indian foreign policy at one place, listing down its successes and failures-or reasons for its shift, as also future strategies.
With the Indian phenomenon growing larger on the international scene, it is important that India is seen as a country with a broad plan on how to deal with emerging geopolitics in the future, rather than a nation that decides foreign policy at whim.
