Assessing the amount of Pseudomonas aeruginosa and the amount of Heavy metals, Lead (Pb) and Chromium (Cr) from household water from different industrial zones of Dhaka Division (Hazaribagh and Savar)

Abstract

Water is the major natural reservoir of the atmosphere - not so much in volume as in time and contact. Water is the indispensable environment resource for human security, the driven force of engines of sustainable socioeconomic expansion. In recent days, due to presence of all types of living organisms and undesirable accumulation of heavy metals in water and their toxic impact on biological systems, the water quality is a concern of paramount prominence to ensure the health of the population around the world. The purpose of this study was to determine the quality of natural water including samples from reservoir and distribution by considering into the microbiological aspect and several physicochemical analyses. Pseudomonas aeruginosa is a bacterial species, which occurs widely in water environment capable of conferring wide range of diseases and have tendency to develop high antibiotic resistance. The magnitude of the heavy metals content of water may pose significant health risks so continuous monitoring of both chemical and biological quality of natural water sources is highly recommended. The literature cited here showed a parallel the assessment of the levels of the toxic chemicals like Lead (Pb) and Chromium (Cr) in two distinct locations, Hazaribagh and Savar, Dhaka city within the period of May2019- November 2019 along with the presence of Pseudomonas aeruginosa. Finally, the results portrayed that 20% of the samples from each area confirmed the presence of P.aeruginosa in the same sample as Lead that was present in 75% of the samples, whereas chromium was absent in all the samples.
