Abstract/ Executive Summary:

An investigation was made to ascertain heavy metals’ concentration in effluent samples collected from different textile and garments industries located in Bhaluka industrial area, Mymensingh, Bangladesh during August to November, 2013. Atomic Absorption Spectrometer (AAS) was used to evaluate the concentration of Zinc (Zn), Copper (Cu), Nickel (Ni), Cadmium (Cd), Chromium (Cr) and Lead (Pb) in the samples. The study revealed that heavy metals were present in variable amounts, where concentrations of Cu (0.0405 ppm) and Pb (0.0003 ppm) were found lower than the recommended level for industrial wastewater. Among the present trace metals, the highest concentration (0.2-1.0 ppm) was found in Zn. Although the concentration was suitable for irrigation, it was unsafe for aquaculture. Besides, all of the wastewater samples possessed no Cr, Cd and Ni, which indicated no possibility of contamination by these metals. However, comparing the findings of this study with the safe limits for industrial wastewater, it was concluded that the wastewater of the whole study area except that of some sampling sites could be used for irrigation and aquaculture.

Commodity: Heavy metal

Objectives:

The present study was undertaken to assess heavy metal concentrations of wastewater dumping sites in Bhaluka industrial area, Mymensingh, Bangladesh.

Methodology:

Study Area: Textile and garments industries, situated in Habirbari union of Bhaluka Upazila, "Mymensingh district" located approximately within latitude at 24.3750ºN and longitude at 90.3778°E were selected to evaluate heavy metal concentration in effluents. Sample collection The industrial effluent samples (E1-E12) were collected during September 2013 from effluent discharging drains originated from six different industries’ outlets. The sampling points (S1-S12) were designed in relation to industries. Samples were preserved for laboratory analysis maintaining with proper direction. Analytical procedures: determination of heavy metals Determination of different heavy metals viz. Zn, Cu, Ni, Cd, Cr and Pb in water samples was done by an Atomic Absorption Spectrophotometer (AAS) (Varian Spectra AA55B, Australia) as suggested by APHA19. A standard line was prepared by plotting the absorbance reading on Y-axis versus the concentration of each standard solution of metal on X-axis. The concentration of metal was calculated by putting AAS reading on the standard line. Data analysis Descriptive statistical parameters were calculated with SPSS software package and Microsoft Office Excel. Various descriptive statistical measures such as range, number, percentage, mean, standard deviation (SD), etc were used for categorization and describing the variables.

Achievement/Findings:

On the basis of the results of the experiment, it can be stated that the level of heavy metal contamination in collected wastewaters from textile and garments industries was generally low and showed an acceptable limit. The objectionable appearance of canal water could be attributed to the discharge of untreated industrial wastewaters. Though some of the chemical elements were beneficial for agriculture and aquaculture up to a certain limit, it might be potentially detrimental beyond that
