Analysis of Metal in Wastewater Collected from Three Pharmaceutical Industries Located in Tongi Area of Gazipur District

Abstract

Wastewater qualities of three pharmaceutical industries were determined during July 2005 to January 2006. Alkaline earth metals including calcium (Ca) and magnesium (Mg) of wastewater ranged 41.79-54.5mgL-1 and 10.5996-32.2926 mgL-1, respectively. Alkali metals including potassium (K) and sodium (Na) of wastewater ranged 3.44-18.98 mgL-1 and 67.57- 128.71 mgL-1, respectively. Transition metal iron (Fe) ranged 1.02-2.13 mgL-1. On an average metals including zinc (Zn), lead (Pb), nickel (Ni) and cadmium (Cd) were in trace amount i.e. 84.32 μ gL-1, 11.59 μ gL-1, 4.96 μ gL-1 and 0.1047 μ gL-1, respectively in the wastewater. Copper (Cu) was undetected in wastewater. The average amount of iron of site N, magnesium of site S and potassium of site B of wastewater were higher than that of the standard of Department of Environment (DoE) of Bangladesh. Key words: Metals; Pharmaceutical wastewater; DoE standards. DOI: 10.3329/bjsir.v45i3.6538Bangladesh J. Sci. Ind. Res. 45(3), 277-282, 2010

Sources, factors, mechanisms and possible solutions to pollutants in marine ecosystems

“…Incorrect drug disposal is particularly important as a cause of pollution by pharmaceuticals (Daughton and Ternes, 1999;Hirsch et al, 1999;Jones et al, 2001;EMEA, 2006;Fent et al, 2006;Islam et al, 2010). It is in this context that a popular initiative by Chinese pharmaceutical manufacturers (the so-called '100 tablets in a bottle') comes into play as a case study of what should be avoided.…”

“…There is more limited regulation concerning the environmental impact of pharmaceuticals, and of effluents released from pharmaceutical industries in China, India, Bangladesh, and other developing countries (EMEA, 2006;Islam et al, 2010).…”
