Most climate related hazards in Bangladesh are linked to water. The vulnerable poor—the poorest and most marginalized communities living remote villages along Bangladesh’s coastal zone that change impacts who possess low adaptive capacity affected by lack of access safe water sources. Many poor households depend on small isolated wetlands (ponds) for daily drinking needs other domestic requirements, including cooking, bathing washing. Similarly, the livelihoods many these also ponds due...

Groundwater provides the largest source of usable water storage in Bangladesh. samples have been analyzed for Fe, Mn, Zn, Ni, Cr, Cu, Cd, Pb, and Co using atomic absorption spectrophotometer to evaluate heavy metal distribution contamination level at southeastern coastal area Heavy metals are range Fe (490–4710 µg/L), Mn (13–1970 Zn (70–550 Ni (42–255 Cr (25–133 Cu (34–95 Cd (7–26 Pb (0–20 (43–141 µg/L). The mean concentration exceeded Bangladesh standards drinking water. Application Pearson...

Abstract On-site radon concentration has been measured in soil gas and ground water using AlphaGUARD PQ2000 PRO (Saphymo, Germany) monitor at the west coastal area of Bangladesh. The samples is range 1.41 ± 0.29 to 3.2 0.59 Bq/l with mean value 2.33 0.50 Bq/l, which lies within safe limit recommended by UNSCEAR (2008). total annual effective dose estimated due ranges from 3.85 8.74 μSv/y 6.37 μSv/y, lower than set WHO (2004) EU (1998). In samples, three different depths (0, 20 40 cm) each...
