Report on Dubai Conference Tour - Dr. Shamal Doifode This is the report on Conference attended by me in Dubai for the International Conference On Natural Science and Environment on 4th and 5th May 2014. Dubai is located on the southeast coast of the Persian Gulf and is one of the seven emirates that make up the country. Abu Dhabi and Dubai are the only two emirates to have veto power over critical matters of national importance in the country's legislature. The city of Dubai is located on the emirate's northern coastline and heads up the Dubai-Sharjah-Ajman metropolitan area. Today, Dubai has emerged as a global city and business hub of the Persian Gulf region. It is also a major transport hub for passengers and cargo. By the 1960s Dubai's economy was based on revenues from trade and, to a smaller extent, oil exploration concessions, but oil wasn't discovered until 1966. Oil revenue first started to flow in 1969. Dubai's oil revenue helped accelerate the early development of the city, but its reserves are limited and production levels are low: today, less than 5% of the emirates' revenue comes from oil. The emirate's Western-style model of business drives its economy with the main revenues now coming from tourism, aviation, real estate, and financial services.

Introduction Water play an important role in human life although
statistic the WHO reports that approximately 36% urban and 65% of rural Indian were without access to safe drinking water . The quality of water is of vital concern for the mankind since it is directly linked with human welfare. The present work is an attempt to measure the water quality of water sources of various site. Ground water sample were collected from 3 various sites of Malkhed Lake, from Amravati district.
Site Information Malkhed Lake: Malkhed Lake is situated at 20° 49’
0”N,77°53’0”E 23 km east to Amravati Maharashtra . Set in hilly region with good forest cover. It is near Chandur Railway town in Pohara-Malkhed reserve forest in Amravati district of Maharashtra state in India. The main water source of this lake is Kolad River. The lake is constructed for irrigation and drinking purpose and was stated to use in 1972 .
Methods of Analysis Physico-Chemical analysis is the prime consideration
to access the quality of water for its best usage say for drinking, bathing, fishing, industrial processing and so on, while for waste water either domestic or industrial to know the pollution strength and its effect on ecology. Physical Parameters : Colour, temperature turbidity , conductivity, total solid , total suspended solid , total dissolved solid , pH can be measured. Chemical Parameters: Dissolved oxygen, total alkalinity, total hardness, calcium hardness, magnesium hardness, acidity can be measure with the help of different methods.

Discussion and Conclusion Temperature is useful for biological activities .it is enhance by
higher temperature. The temperature of Malkhed Lake water of all 3 sites is same due to specific environmental conditions. The colour of water for all 3 sites is light turbid due to low level of water. The turbidity of lake water found at all 3 sites is more than permissible limit. H+ concentration expresses the intensity of the acidity and alkalinity of the water. It plays limiting role in the growth of flora and fauna of aquatic body. The pH value plays great importance because chemical and biochemical reactions in aquatic body take place at particular pH value. The pH value of all three sites of Malkhed Lake is neutral i.e. permissible range for drinking water. Conductivity of Malkhed Lake water was near about same due to total solids. It must have the cause for the electric conductivity.
Discussion and Conclusion Total dissolved solids of 1st site were found lower than other two
sites. Dissolved oxygen was found to be higher at 2nd site than other two. Total alkalinity of water is found more at 1st site than two others. The Ca and Mg salts largely combines with carbonates, sulphates, chlorides content are responsible for hardness of water. The surface water is less hard than ground water. Total hardness was found more at 3rd site while that of other two was also more than the permissible limit. The calcium hardness of 3rd site was higher than the other two but all the three readings under permissible limit.
