Ready-Made Garments (RMG) is the biggest sector in Bangladesh where a large amount of waste streams or effluents is produced. The presence of heavy metals in industrial waste water is one of the main causes of water and soil pollution in Bangladesh. The present research was carried out on eight garments industries of Gazipur region that are using Effluent Treatment Plant (ETP) for the waste water management. In this investigation the heavy metal (Cd, Pb, Hg, Ni, As, Cr, Cu, Zn, Mn, Sb and Co) contents in the 24 samples of different garment industry's inlet water and waste water (before and after treatment) were determined. In most of the cases the Cd, Pb, Hg, Ni, As, Cr, Sb and Co content are not too high in the waste water and can be reduce to tolerable range with the ETP, whereas the textile manufacturing process discharge huge amount of Cu, Zn and Mn to the waste water and these metals content in the waste water even after treatment are beyond the tolerable range.
The concentrations of heavy metals were determined in tannery and textile effluents and water of adjacent rivers (Buriganga and Karnatoli, Dhaka) from September 2006 to August 2007 at three different locations. Concentrations of Zn, As, Cd, Pb, Ni, Cr and Cu of tannery effluents seasonally varied from 7.65-14.82, 0.45-1.07, 0.25-1.91, 2.89-4.03, 4.02-9.5, 1256-2173.13 Pg/L and BDL respectively. In textile effluents Zn, As, Cd, Pb, Ni, Cr and Cu concentrations were seasonally varied from 14.26-39.86, 4.5-6.6, 0.23-0.65, 0.96-3.89, 3.5-6.83, 1.16-3.85 and 11.6-39.23 Pg/L respectively. The variation in concentration of heavy metals was due to the use of different raw materials and variation of production level. The concentrations of Zn, As, Cd, Pb, Ni, Cr and Cu of Buriganga River water seasonally and spatially varied from 5.2-62.07, 1.76-3.53, 0.11-2.37, 1.18-8.59, 1.15-6.44, 9.45-293.08 Pg/L and BDL respectively whereas in Karnatoli River the concentrations of Zn, As, Cd, Pb, Ni, Cr and Cu were seasonally and spatially varied from 0.62-68.47, 0.56-1.91,0.13-1.53, 0.53-6.8, 4.2-8.2, 2.75-7.0 and 8.6-48.14Pg/L respectively. Lowest concentrations of heavy metals were observed during rainy season which might be due to the dilution effect of rainfall whereas the highest concentration of these metals were found during dry season as industrial effluents are less diluted due to recede water in the river in this season. Some of the heavy metals concentrations are higher than the recommended value, which suggest that the Buriganga and Karnatoli River are to a certain extent heavy metal polluted river.
Pollution is an important problem in human and aquatic life that leads to a miserable condition. There are many kinds of pollution but textile industry is mainly by the release of wastewater containing dyes and chemicals, coming out from wet processing like de-sizing, scouring, bleaching, mercerizing, dyeing, printing and finishing. In present investigation, the physico-chemical analysis and heavy metals concentration are pH, TDS, TSS, BOD5, COD, Total alkalinity, sodium, sulfate, phosphate, chloride, chromium, cadmium, copper, iron, nickel, lead and zinc were found within the permissible limits. Concentrations of all these metal ions in the effluent were above the recommended NEQS. The effluent samples were evaluated to ascertain the efficiency of industries wastewater treatment process. Conventional methods were employed for determination of physico-chemical parameters while; heavy metals in the textile effluent sample were analyzed using an Atomic Absorption Spectrophotometer (AAS).
The present study was conducted to assess the contamination of heavy metals in the industrial waste waters collected from Dhaka city, Bangladesh. Three different types of industries (tannery, dye chemical and textiles) have been considered as the major sources of untreated effluents. Metals were analyzed using inductively coupled plasma mass spectrometer (ICP-MS) and compared with different international standard values. The ranges of Cr, Ni, Cu, As, Cd and Pb

Dispersion of heavy metals in textile effluent and pond environment in Panipat industrial area
Environment Conservation Journal
The Panipat region is well known textile industrial zone of Northern India and have a large number of dye houses and textile processes units. The dyeing house industries uses a large volume of water for wet dip coloring process and draine most of the waste water as effluent. The effluent containing composite mixture of different pollutant in terms of heavy metals. Metal accumulation in sediments provides a record of the spatial and temporal history of pollution from surface water to ground water. The dispersion of heavy metals from textile effluents to adjoining pond system ultimately affect quality of water. The present study revealed that pond sediment found highly polluted regarding heavy metals load. Transfer factor for Fe, Mn, Ni and Pb was found very high in pond through open effluent drainage system.

Environmental problems of the textiles industries are mainly cause by the discharge of wastewater coming from the dyeing and finishing processes containing the heavy metals. This study assessed the heavy metals concentrations in the surface water body of neighboring Funtua and Zaria textile industry and effluent water collected from Funtua textile industry using atomic absorption spectrometer (AAS). The concentrations of heavy metals like Lead (Pb), Cadmium (Cd), Iron (Fe), Zinc (Zn) and Coppernicium (Cn) were assessed and the concentrations of each of the metals varies in the samples collected and analyzed with the following values: Funtua water samples Fe 0.0025 mg/l lower part and 1.63 mg/l upper part, Zn 0.51 mg/l lower part and 1.02 mg/l upper part, Pb 0.007 mg/l lower part and 0.61 mg/l upper part, Cd 0.01 mg/l lower part and 0.016 upper part, Cn was not detected (ND), for effluent Fe 3.61 mg/l and 2.61 mg/l, Pb 2.66 mg/l and 2.69 mg, Cd 0.99 mg/l and 1.06 mg/l, Zn 2.26 mg/l and 2.99 mg/l, Cn ND also and for Zaria water samples Fe 0.96 mg/l lower part and 2.15 mg/l upper part, Zn 1.07 mg/l lower part and 1,74 mg/l upper part, Pb 0.36 mg/l lower part and 1.02 mg/l upper part, Cd 0.41 mg/l lower part and 0.66 mg/l upper part and Cn ND also. Fe and Pb showed concentrations higher than limits set by the NSDWQ and WHO while Zn and Cd showed concentrations below limits set by NSDWQ and WHO. The river neighboring Zaria textile happened to be more polluted than the one neighboring Funtua textile industry. It was concluded that the effluent samples of textile industries discharge causes pollution to the water bodies and serious problem for living being and ecological environment. Therefore, the effluent water to be discharged by these industries must be adequately treated before discharge.

The textile industry consumes large quantities of water that causes serious problems for aquatic organisms and human accordingly. This study aimed to verify the pollution caused from textile industry wastewater by determination of the concentration of some heavy metals (Co and Cd), COD and BOD. Three samples of sewage (cotton washing stage (S.No1), fabric dyeing (S.No2), fabric printing(S.No3)) were collected and analyzed by Atomic Absorption Spectrometer (AAS) to determine the concentration of cadmium(Cd) and cobalt(Co), then, BOD and COD also were determined. The results show that the concentration of Cd in the dyeing and printing stage (0.031-0.014) ppm is high compared with the permissible limit of (WHO). The concentrations of Co in the three samples were higher than the permissible limit. COD, BOD presented also higher than the permissible limit in the two last samples (3690.0, 2630.0-2120.0, 1926.50) respectively. These results show that wastewater of textile industry pollutes the environment and causes harms for aquatics and human. The study recommends that the wastewater of textile industry must be treated before it flowed to the Nile water.
