This study was carried out to check the effectiveness of Calotropis procera latex for bioremediation and to compare its efficacy with Moringa oleifera leaves extract. It was observed that considerable reduction in various physicochemical and bacteriological properties of the samples took place with Calotropis procera latex. After 1 hour of treatment itself, it carried out pH reduction of 11.11%, 30.00% and 12.50%, while Moringa oleifera leaves extract carried out 0.00%, 20.00% and 0.00% reduction and after 24 hours, turbidity was reduced to 90.00%, 61.87% and 65.36% with Calotropis procera latex and 75.00%, 60.43% and 32.03% with Moringa oleifera leaves extract for Vanki river water, Textile effluent and Paper & Pulp Industrial effluent, respectively. Vanki river water showed a reduction in TSS and TDS of 2000 mg/L and 34000 mg/L with Calotropis procera latex and 3000 mg/L and 46000 mg/L, respectively with Moringa oleifera leaves extract. With Calotropis procera latex, the COD and BOD values were 544 mg/L, 608 mg/L and 800 mg/L; and 0.04 mg/L, 0.240 mg/L and 0.012 mg/L for Vanki river water, Textile effluent and Paper & Pulp Industrial effluent, respectively. When treated with Moringa oleifera leaves extract, the COD values reduced to 864 mg/L, 800 mg/L and 896 mg/L and BOD values reduced to 0.004 mg/L, 0.251 mg/L and 0.022 mg/L, respectively. The total coliform count reduced to 130 MPN/100 ml, <1.8 MPN/100 ml and 7.8 MPN/100 ml for Vanki river water, Textile effluent and Paper & Pulp Industrial effluent, respectively after treatment with Calotropis procera latex. Thus, Calotropis procera showed better results in comparison with Moringa oleifera. So, it could be considered as the best alternative to prevent pollution.

As a developing country, industrialization is rapidly growing up in Bangladesh. Most of the cases, the industrialization process don’t considering any impact on environmental body. In this study, the impact of unplanned industrialization on the surface water is the main focus. In between several resources, the water quality of the Sitalakhya River is our study area. Quality of the Sitalakhya River water is getting polluted day by day through industrial effluents and household wastewater, lube oil and oil spillage around the operation of river ports. The Sitalakhya river water quality analysis is considered between 1975 to 2018, qualitative and quantitative results for pH, DO and BOD were analyzed and also trends of these parameters were also analyzed. Day by day river water quality going far away from EQS value, which is significantly harmful to flora fauna. In this circumstance, industrial effluent and other environmental impacts from unplanned industrialization is main goal of this study. This study shows, how unplanned industrialization can damage an environmental system which is very harmful to our entire ecological cycle. If cannot control this unplanned industrialization, water body will damage and all related ecosystem will be effected.

The bacterial isolate Bacillus sp. AZ28, obtained from industrial effluent, demonstrates a great capacity to degrade various azo dyes (methyl orange (MO), magneson I (MI), novacron dark blue (NDB), and novacron red FN 3GF (NRF3)), and azo dye-containing textile effluent (TE). The degradation was evident by decolorization of dyes, and the decolorization efficiency of 84-95% was achieved within 14-72 h under optimum conditions, such as 37˚C, pH 7, inoculation size 8%, 1% glucose, and 1% beef extract. The extent of decolorization of individual dye was determined by UV–Vis spectroscopy, and products of biodegradation were analyzed by FTIR spectroscopy and TLC analyses. Chemical analysis showed that the COD and BOD values were significantly reduced after treatment. Thus, the biodegradation ability under mild conditions suggests that Bacillus sp. AZ28 has potential in textile effluent treatment. J. Bangladesh Acad. Sci. 45(1); 117-122: June 2021

The present study was undertaken to investigate the occurrence of some selected microorganisms in industrial effluents and in the river Buriganga and Karnatoli, which receive the industrial effluents directly from industries, with a view to evaluate the effect of industrial effluents on river. The total viable bacterial count (TVBC) in both tannery and textile effluents were slightly higher in dry season than those of rainy and summer. The TVBC in Buriganga River ranged from 3.4 × 105 to 9.6 × 105, 2.2 × 104 to 1.2 × 105 and 7.2 × 104 to 4.5 × 105 cfu/ml in dry, rainy and summer seasons, respectively, and the TVBC in Karnatoli River ranged from 4.9 × 105 to 5.4 ×106, 1.2 × 105 to 1.0 × 105 and 5.3 × 104 to 3.8 × 105 cfu/ml in dry, rainy and summer seasons, respectively. Pseudomonas spp. in effluents and river water were also slightly higher in dry season than that of rainy and summer seasons due to increase in water level. The total coliform and fecal coliform counts of the industrial effluents and discharge point in the river were always very high, which was >2.4 × 103cfu/100 ml in all seasons as measured by the MPN method. Salmonella, Vibrio and Staphylococcus were frequently isolated from all the sampling points throughout the year with a few exceptions. This study indicates that the water of the river Buriganga and Karnatoli is heavily contaminated with both industrial wastes and domestic sewage materials. The bacteriological state of the water of the rivers is comparable to that of the effluents. The presence of pathogenic organisms may pose health hazards to the users of the river water and also poses risks for the aquatic organisms especially fish of the water bodies.

Tramadol, a broadly in recent years, is an effective analgesic agent for the treatment of moderate to acute pain. Its metabolites are excreted by the kidney which may cause nephrotoxicity. Moringa oleifera leaves are commonly used to provide herbal and plant-derived medicinal products especially in developing nations. The present study was carried out to determine the biochemical and histopathological changes in the kidney of tramadol-treated albino mice and to evaluate the possible protective role of Moringa oleifera leaves against tramadol-induced nephrotoxicity. Twenty adult albino mice were divided into four groups. Control group (group i) received daily intraperitoneal injection of normal saline only, group ii received oral dose of Moringa oleifera leaves extract (20 mg/kg/bw) for three weeks, group iii received daily intraperitoneal dose of tramadol (0.3 mg/kg/bw) for the same period, group iv, received daily oral dose of Moringa oleifera leaves extract, (20 mg/kg/bw) three hours before injecting intraperitoneal dose of tramadol (0.3 mg/kg/bw), for the same period. Blood samples were withdrawn at the end of the experiment for kidney function tests and specimens from the kidney were processed for histological study. No significant differences in the mean values of the kidney function tests were noticed between Moringa oleifera group and control group. However, there was highly significant increase in the mean values of serum, urea and creatinine in tramadol-treated group as compared to the control group. Although tramadol + Moringa oleifera group revealed significant difference in the mean values of urea and creatinine when compared with tramadol-treated group. So, Moringa oleifera leaves extract have been shown to attenuate the renal dysfunction, improve the renal architecture, with nearly normalization of serum urea and creatinine levels which indicate improvement of renal function. In conclusion, in the light of biochemical results and histological findings, co-administration of Moringa oleifera leaves lessened the negative effects of tramadol-induced nephrotoxicity; possibly by its antioxidant action. Further investigation of these promising protective effects of Moringa oleifera leaves against tramadol-induced renal injury may have considerable impact on developing an adjunct therapy aiming to improve the therapeutic index of some nephrotoxic drugs.
