Background. Exposure to cadmium (Cd) is a global public health concern. The primary Cd exposure pathways are inhalation and ingestion. Globally, Cd production and consumption has increased, along with nickel-cadmium battery production, alloys, anticorrosive coatings, pigments, polyvinyl chloride stabilizers, semiconductors for solar cells, etc. After the end use of these elements, improper management may cause Cd pollution in different spheres of the environment and living organisms that eventually lead to adverse effects on human health. Objectives. The aim of the present study is to demonstrate the sources and routes of Cd that enter different environmental spheres, their concentrations, and describe associated human health impacts in Bangladesh. Methods. The present study searched a total of 304 peer-reviewed articles in the National Center for Biotechnology Information database, Science Direct, Web of Science, Springer Link, BanglaJOL, and university libraries and ultimately selected 71 articles. Afterwards, the relevant findings on Cd exposure through inhalation and diet and age-based impacts (i.e., adults, women, children and infants) in Bangladesh were combined. Finally, the results were processed with a cross-tabulation technique. Results. The present study found that Cd concentration in the local diet and river water is within the World Health Organization and Bangladesh Standard Testing Institute guidelines. Discussion. The concentration of Cd in sediments is comparatively higher than in river water in Bangladesh. Cadmium has been found in samples of foods, including leafy and non-leafy vegetables collected from different places in Bangladesh and may ultimately enter the human body via dietary intake of these foods. Consequently, individuals may be exposed to Cd and may be suffering from long-term adverse health effects. Conclusions. The comparison of concentrations in this study with national and international standards will assist with the formulation of effective pollution mitigation measures in Bangladesh.

Microbiological health risks due to environmental pollution are major concerning issue in all over the world. In Bangladesh, almost all the major water bodies (lake/khal) particularly in the urban or semi-urban area have been suffering severely pollutions. Therefore if we manage to safe our surface water in and around the city, we can reduce the demand of ground water for the city dwellers by the proper use of these lakes and ponds. This study was conducted to evaluate the microbial condition of Hatirjheel water located in Dhaka City. The microbial analysis was performed to trace the presence of bacterial and other pathogens. In 5 samples, total viable bacteria and fungi were found up to 2.0×106 cfu/ml and 3.4×102 cfu/ml, respectively. Specific pathogens such as Klebsiella spp. (3.0×102 cfu/ml), Salmonella spp. (2.0×102 cfu/ml), Pseudomonas spp. (8.3×102 cfu/ml) and Vibrio spp. (6.0×102 cfu/ml.) were also isolated. The findings of the study revealed that the water of Hatirjheel might not safe for human health and also indicated that this water may vulnerable for diarrhea, dysentery, typhoid fever, shigellosis, salmonellosis, parasitic worm infection, hemolytic uremina syndrome etc. water-borne diseases. The poor water quality suggesting contamination of the lake water by domestic and industrial wastes and other anthropogenic activities. So it is important to control the pollution for proper use of this water in various household purposes.Stamford Journal of Microbiology, Vol.6(1) 2016: 30-33
