    Abstract This paper deals with the environmental impact of effluents released by denim garment washing factories in Bangladesh. Both untreated and treated effluent samples were collected from five denim washing factories identified as representative cases and were subjected to chemical testing as a part of the case study. The results were compared against the acceptable limits of parameters-chemical oxygen demand (COD), dissolved oxygen (DO), biochemical oxygen demand (BOD), total dissolved solids (TDS), total suspended solids (TSS), the potential of hydrogen (pH) and color. Findings show that COD and BOD values are well within the acceptable limit in all of the factories studied but only 20% of the factories could achieve acceptable DO levels. Around 40–60% of the studied washing factories showed evidence of improved filtration systems for TDS and TSS values, but only 40% of factories produced clear wastewater. 60% of the factories met an acceptable pH level of 6–8 before releasing their effluent to the environment. The study reveals the technical limitations of effluent treatment practices of the denim garment washing factories in Bangladesh. The findings will appeal to all stakeholders, including academics and researchers, to give serious attention to reducing environmental impact of industrial garment washing process. They will help industry practitioners with more comprehensive information to take strategic action in making denim garment washing factories in Bangladesh more sustainable.

    Abstract We herein report the optimization and application of silver cationization (Ag+) in combination with laser desorption ionization (LDI) ultrahigh-resolution mass spectrometry (UHR-MS) to determine the structures of the sulfur-containing compounds present in heavy crude oil. A number of sulfur-containing model compounds were used to optimize the positive-ion mode LDI-MS conditions in the presence of a silver-complexing agent. Under the optimized LDI conditions, sulfur-rich heavy oil fractions were treated with the silver salt, where Ag+ coordinated with the sulfur atoms to speciate the sulfur species. The obtained results suggested that benzothiophenic, naphtheno-non-aromatic sulfides, and non-aromatic thiols were the major components present in the analyzed oil sample. Graphical abstract
