Water pollution is one of the current global *** many countries are suffering from this problem specifically most South Asian and Southeast Asian countries,and Bangladesh is one of those countries that are suffering from water ***,the city of Bangladesh,Dhaka is one of the most densely populated cities in the world and overpopulation is showing a negative impact on the water quality *** of the rivers are very polluted around Dhaka city because of anthropogenic *** study focused on buriganga river pollution and its impact on public *** study intended to find out the major cause of buriganga river pollution and the health status of the community living beside the buriganga *** the study identified all the common diseases which people are suffering from around the buriganga river *** the study compared the results with other southeast Asian countries so that it can make the relationship and can make it easier to understand the current situation of water pollution on public health in East Asia and Southeast Asia *** the research work,it was noticed that the buriganga river is very polluted due to human *** transportation system,fishing,and waste canals from industries become the primary reasons behind buriganga’s current *** irresponsibility of both the environmental department and civil society is the major factor in buriganga river *** hygienic level was also not in a good condition because so many wastes like plastic materials and other daily use materials were thrown out into the ***’s why public health conditions around the buriganga river become vulnerable *** policies have to be implemented from the right perspective and the institutions have to be strong enough to handle all the issues regarding the buriganga River.

Encroachment of the buriganga River in Bangladesh

A survey on different aspects of buriganga River encroachment was conducted in a 300 meter long encroached part of the river located in Dhaka, Bangladesh. A total of 100 respondents were surveyed and three Focus Group Discussions (FGDs) were arranged prior to the semi-structured questionnaire survey. It was observed that almost all of the respondents migrated to the study area. The majority of the respondents had better business opportunity (69.23%) as the cause of encroachment. Significant portions of the respondents occupying the encroached area were found to be landless (36.84%), small businessmen (31.58%) and people with political affluence (26.32%). Major portions (23.33%) of the encroached land were used for industrial development as well as housing and developmental projects. Negative health impact (40%) was found to be the main adverse effect of encroachment of the river. Other adverse effects included economic loss through obliteration of fisheries (35.71%), scarcity of clean water (32.14%), reduction of aesthetic value of the surroundings (25%) etc. For the protection of the river, the majority of the respondents opted for relocation of the industries (46.15%) and enforcement of strict rules and regulations (38.46%).

This research investigated the water qualities and distribution of heavy metals concentration in rain, river, ground and supply waters, providing a baseline in Dhaka Urban, Bangladesh, against which future changes can be assessed. The water sample was collected in the Dhaka central zone, from a site located in the center of the Bengal Delta plain between 23䓨'N - 23䓶'N latitude and 90䓔'E - 90䓟'E longitude which is affected by environmental pollution for high traffic, industrialization and because of its rapid urbanization. The water samples were analyzed for heavy metals by Inductively Coupled Plasma Mass-Spectrometry (ICP-MS), major ions by Ion-Chromatography (IC), water tracer (δ18O and δD) by Mass-Spectrometry (MS), following the standard techniques. Elevated EC and chloride (Cl-) are the markers of wastewater, providing an indication of impacts in the buriganga River water. The relative concentrations of major ions were presented in the form of Piper and Stiff Diagram. The color maps were constructed to present ions distribution over the areas. The stream reaches directly in buriganga River from leather industries which may reflect the naturally low dissolved oxygen (DO) 0.3 - 3.5 (mg/L), where aquatic life can’t survive. Uranium contents U238 (0.1 - 2.7 μg/L) are not exceeding the WHO guideline level of 30 μg·L-1. Significant portion of Cs133 (0.05 - 0.32 μg/L), Se (0.03 - 0.12 μg/L), B (50 - 2986 μg/L) and Cr (0.55 - 18.59 μg/L), could be increased in buriganga River areas by the effect of local sources like leather industry. Zn (10 - 1466 μg/L) in the Dhaka Rain and Pb (4 - 6 μg/L) in Dhaka Water occur mainly in industrial and the high traffic areas, respectively. The isotopic (δ18O/δD) distributions have been evaluated for understanding of contaminant sources in groundwater and wastewater recharge from buriganga River to adjacent depleted groundwater system. The results indicate that the magnitude of pollution problem depends on th
