National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow closer to the canal during rainy season. Present investigations have enabled identifying four possible sites from where Gomti river could be fed with the Sarda river water. This storage of additional water of Sarda river in Sarda Sagar and subsequently its diversion into the Gomti river would have a two fold benefit. The large scale inundation caused by over spilling of Sarda river banks could be mitigated to a certain extent, and more importantly this excess ‘waste’ water of Sarda river could be meaningfully utilized to save the life of the ‘little sister’ Gomti river. Similar exercise of possibility of diverting, the excess water of Garra/Deoha river into the upper reaches of Sai river have also been studied. The continuous chain of abandoned river channels in the area between Garra/Deoha river and Sai river, could again be activated through dredging and used as a conduit to carry the Garra river water into Sai river. The re-activation of these ‘dying’ smaller rivers would be a first step towards attempting to salvage the entire network of river systems in the Ganga basin. PROLIFICATION OF ARSENIC IN GROUND-WATER OF DISTRICT BAREILLY, U.P. - CASE STUDY M.A. Faruqi and K. Khan Central Water Analysis Laboratory, U.P.Jal Nigam, Lucknow – 226001 It is a well known fact that the consumption of arsenic contaminated water leads to chronic health effects. Signs of chronic arsenic-ailments include dermal lesions, peripheral neuropathy, skin cancer etc. The presence of Arsenic in ground-water has been reported from many parts of the world particularly in the Bengal Delta and Bangladesh, China, Vietnam and Nepal. In 1976 Arsenic contamination was reported from some states of Northern India including U P. In 1984 groundwater Arsenic contamination was discovered in lower Ganga Plain of West Bengal, in 2001 groundwater Arsenic contamination in the terai area of Nepal came to notice. In June 2002 Chakraborti et al. discovered Arsenic contamination in Bihar in middle Ganga plain and at the same time apprehended contamination in U.P. lying in middle and upper Ganga plain. Arsenic contamination was detected in U.P. in 2003 by the team from Jadavpur University in three Blocks of Ballia district. In 22 villages, Arsenic was found at concentrations of 50 ppb or higher. The highest concentration reported was 1000 ppb. In 5 villages case of Arsenicosis was detected and skin lesions typical of Arsenicosis were found in 53 of the 307 people screened. Bareilly district borders Pilibhit and Shahjahanpur on east and Rampur on west, Udham Singh Nagar in north, Budaon in south. It is a level terrain watered by many 44
National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow streams. The river Sarda or Gogra forms the eastern boundary of the district, next is Ramganga and Deoha, the Gomti also passes through the district. Bareilly district was selected for this survey on the basis of its central location and as a part of terai region of U.P. On random basis this survey was conducted in 176 villages of 9 Blocks of the district and water samples from 2532 nos. of India Mark II hand-pumps were analysed using the standard method of Arsenic analysis. The outcome of the survey in detail is given in this deliberation block-wise. Though, the situation of Arsenic proliferation in groundwater of Bareilly is not alarming but the study gives a ground for an early pondering over it before it goes beyond our control. AIR POLLUTION DUE TO PARTICULATE MATTER (PM) AND HUMAN HEALTH S.C. Barman Environmental Monitoring Division, CSIR-Indian Institute of Toxicology Research, Mahatma Gandhi Marg, Lucknow 226 001 Epidemiological studies suggest that air pollution due to Particulate Matter (PM) is one of the major concerns because human health is at risk and a large number of people are exposed to it in urban and industrial areas. PM, an ambient air criteria pollutant, has size ranging from nanometer to 10 μm and can be aspirated into the lung airways. Smaller PM cause severe adverse effects on health. PM is a complex mixture of chemical agents of different shapes and sizes. Recent studies reveal that the effect of PM on human health will depend on the chemical composition of PM, besides its number and mass concentration. At present PM standard in ambient air is limited to the mass concentration within two specified size ranges PM 2.5 (< 2.5 μm) and PM 10 (< 10 μm,). At elevated levels at both size ranges, mortality and morbidity of humans have been reported. The routine air monitoring data on components of the PM mass is essential for epidemiological studies which may identify the chemical constituents of PM which cause health effects and also the source. This paper reviews the recent studies on air pollution due to PM and implementation of regulatory standard. 45
