Malpe Talks About Ill Effects of Excess Fluorine in Groundwater at GGS AGM 2019

                                                  And Child Prodigy Sreenabh Agrawal Feted

The Gondwana Geological Society organised it’s AGM on Tuesday 17 December 2019. Prof D.B. Malpe of the PG Geology Department delivered a talk on “Sources and Health Effects of Groundwater Fluoride Contamination” and the child prodigy Sreenabh Agrawal, 16, a student of Std XI of CDS School, Nagpur, with his galaxy of achievements and records at this young age, was felicitated.

Dr Malpe said that the tolerable content of fluorine in water is 0.6 mg per litre, whereas the Bureau of Indian Standards suggests 1.0 mg/l  and the World Health Organisation recommends 1.5 mg/l.  In tropical countries, the consumption of water is higher and hence the threshold of 0.6 to 1.0 mg/l is acceptable. Dental fluorosis results in case of excess fluorine.  During the 1930’s excess fluorine content was detected in cattle in Nalgonda dist, and later also found in humans for the first time in India. Fluorine enters the body through ingestion, inhalation and rarely through the skin surface.  The content of fluorite, fluorapatite, cryolite, apophyllite in country rocks and also through soil and clay minerals replacing hydroxyl minerals are causative factors for groundwater fluorine contamination, Prof Malpe said.  Fluorite veins, amphibole and mica and fluoride rich hydroxyl minerals decompose and alkaline waters with pH of 7.6 to 8.6 and so also high content of total dissolved salts (TDS), aid higher fluorine content. High nitrate concentration, poor sanitation around bore wells and dug wells are also responsible factors. Dental caries, skeletal fluorosis (with fluorine at 4 to 8 mg/l of water), arthritis, stiffness of joints and rheumatism are common in the people living in such fluoride endemic areas. Poker back, with the spine becoming stiff and the person unable to bend his neck  is also reported in such areas according to Prof Malpe. Non-skeletal fluorosis includes reproductive, gastro-intestinal and other diseases reported from such areas, with fluorine contamination.  Prof Malpe and his team’s study focused on 3602 persons of which 3268 were selected for health surveys in parts of Wardha and Chandrapur dists.  The faculty of Sharad Pawar Dental College and Jawaharlal Nehru Medical College, Sawangi Meghe, Wardha, helped with their support for the case studies. The persons were divided into three age groups of (1-18), ( 19-60) and (60 plus) and were rated as suffering from low, normal, moderate and severe categories of fluorosis. The preponderance is low among the lower age groups, while dental fluorosis cases are maximum in the 60 plus age group. Males have reported 60 %, while females report 40 % of the total cases,  which is due to the fact that many females join in-laws place later in life, but are brought up in non- fluorine endemic areas. Besides, as they are engaged in hard labour the water consumption by males is higher, which affects them Prof Malpe said.  Normal kidney function is very important and impaired renal function with lower excretion, results in retention of fluorine in the body. Remedies to treat the excess fluorine content include creation of Deflourination plant (Nalgonda technique) and treatment in water buckets activated with alumina. Defluorination technique is not successful. The villagers in such areas  have been provided water buckets with alumina by the authorities. Alumina has to be replaced every one year or so, but is not regularly done. Ground water artificial recharging can help minimize fluorine content. The authorities are supplying good quality, potable water from other areas in many villages, but not all villages under the study areas are catered to.  Besides mass awareness programmes, with education of the masses is the need of the hour. If calcium and phosphorus rich diets are taken fluorine retention can be checked. Mid-day meals need to be nutritious for children, Prof Malpe said.

Child prodigy Sreenabh Agrawal , 16, had presented a research paper entitled  “‘Viyog’- grey water segregation for conservation: a green method using Typha Elephantina”, during the very recent GGS National seminar on challenges in ground and surface water resources and has now the distinction of being the youngest researcher to present a paper in all the 16  GGS national symposiums since 1993 till date. He was felicitated with a memento by Dr Anjan Chatterjee, President, GGS, for his sterling achievement. The child’s bio data runs into 27 pages with national and international level achievements and is a matter of inspiration for one and all. Sreenabh spoke on the occasion and thanked the organisers.

Dr P.B. Sarolkar, Secretary, conducted the proceedings. Dr Samaya Humane presented the Treasurer’s report, and Prof A.M. Varade as Organising Secretary, gave an account of the just concluded national seminar. Seated on the dais were Dr P.B.Sarolkar, Dr Anjan Chatterjee, Prof A.M. Pophare, HoD, PG Geology Department. The vote of thanks was proposed by S.N. Girhe, ex Sr Chemist, GSI. 

Dr P.K. Jain, Chief Mineral Economist, Indian Bureau of Mines, Nagpur, delivered the Foundation lecture on the Mining Scenario in India at the 37^th AGM of the Gondwana Geological Society, at the Conference Hall, Directorate of Geology and Mining hqs., Govt of Maharashtra, Nagpur  on 12.10.2018 .

India’s mining sector has been undergoing a progressive change with paradigm shifts in mining laws and policies, since the past few years. It provides direct employment to 4.88 lakh people (2015-16) of which 0.78 lakh are in the metallic, 0.29 lakh in the non-metallic and 3.81 lakh in the fuel (coal and energy sectors), apart from the millions of jobs it creates indirectly. The per capita consumption of minerals is 61 Kg in urban and 10 Kg in the rural sector. The world average per capita consumption is 256 Kg. India is the world’s third largest producer of steel. The annual production of steel is 102 million tonnes and we aim to reach 300 million tonnes by 2030. Uninterrupted raw material supply is essential for sustained growth. In 2016, India’s mining sector contributed Rs 308,200 crores to the economy. To enable the mining sector increase its contribution to the nation’s GDP from 2.5 % as of now to the targeted 4 %, we need to augment our mineral resources, enhance innovation and technological upgradation, create better infrastructure and human resources and provide speedy mineral concessions.  It is important to also develop technology to extract valuable by-products which we are not able to at present. Gallium, used in semiconductors is a valuable by-product of aluminium ore bauxite and  is not optimally extracted in India. India has imported Rs 738,788 crores worth of minerals and metals during 2015-16, whereas our export earnings were only Rs 170,946 crores during 2015-16 .

The fuel minerals have a greater share in production, whereas metallic and non metallic minerals have a lesser share, value wise. Chhattisgarh, Jharkhand, Odisha and Rajasthan lead  in mineral production in the country. In world resources rankings, we are among the top ten countries in respect of coal, iron ore, manganese, aluminium ore, chromium , zinc and magnesium ore.  The expenditure in mineral exploration by India is US $ 17 per square km , whereas it is $ 124 and $ 118 in respect of Australia and Canada. This needs to be increased substantially. Of India’s entire Obvious Geological Potential (OGP) area of 0.57 million sq. km, identified by GSI, only 10% has been explored and mining is taking place in 1.5 – 2% of this area.

The reform measures needed are more transparency, effective solutions to social problems and tribal issues, addressing infrastructure development of mining areas and achieving uniformity in the lease period which is now fixed at 50 years. The scope for deep seated mining and offshore mining are tremendous, which are expected to meet our future requirements.

Five star rating for mining companies has become compulsory, which ensures their compliance with environmental, safety and labour friendly laws. Illegal mining is firmly dealt with in the new Mines and Minerals (Development and Regulation) Act of 2015 (MMDR Act). This Act also provides security of tenure, grant of prospecting and mining licences, transferability of lease  and foreign direct investment (FDI)  in the mining and exploration sectors.

The MMDR Act 2015 has created transparency in grant of leases through auctions. The auctioned blocks have generated Rs 220,000 crores of revenue, of which Rs 181,000 crores has been collected. The new National Mineral Exploration Trust Fund (NMET) collected on the basis of this Act is now valued Rs 1400 crores, that is expected to be used for exploration purposes. The District Mineral Funds generated Rs 21,000 crores through the cess, that has enriched mining districts and are to be used for the respective district’s welfare.

The minor mineral list has been enhanced to include 31 minerals, that has made it easier for state governments to issue mining lease licences. The export duty on iron ore has been reduced from 10 and 30 % to 0 % for ores with less than 58 % iron content.

A new national mineral policy is under finalization which is expected to have special courts to try mining offences and impose penalties.

Industrial growth and GDP are linked to the mining sector’s growth. Land acquisition is still a grey area and the FDI inflows obtained are low and not as per the expectations.

The mining sector has witnessed major reforms during the last five years and more is expected in the coming years.
