Summary: Textile industries produce wastewater with harmful azo dyes that are known to be carcinogenic and mutagenic. This study evaluates the potential use of enzyme immobilized biochar for removing azo dyes from real and simulated textile effluents. The results show that the enzyme immobilized system can achieve high removal efficiency for individual azo dyes in the simulated effluent and for one dye peak in the real effluent. The presence of metabolite in the real effluent indicates the degradation of the dye. Therefore, enzyme immobilized biochar system can be used for simultaneous adsorption and degradation of toxic azo dyes from real effluents.

Summary: Graphitic carbon nitride (g-C3N4) was used as a sacrificial substructure and two-dimensional support to synthesize magnetic CoFe2O4/g-CN composite via a one-step solid combustion method. The composite exhibited excellent magnetic separation and photocatalytic degradation of reactive dyes (RDs) under UV irradiation. Radical-based degradation was confirmed as the dominant mechanism, and the degradation and mineralization pathways of RDs were proposed through LCMS/MS analysis.

Summary: Textile wastewater, containing multiple types of dyes and chemicals, was treated using attached growth bioreactors constructed with sludge, alkalophilic, and thermophilic bacterial consortia. The study showed high color removal efficiency and COD reduction by the bacterial consortia, with the thermophilic consortium achieving maximum decolorization and the alkalophilic consortium attaining maximum COD reduction. The treated dye mixture was confirmed to be non-toxic, indicating the potential of using microbial consortia for biological treatment of dyeing effluents on a larger scale.

Summary: Textile effluents from dyeing processes pose significant problems for aquatic ecosystems and human health. This research presents the optimization of a feasible and efficient treatment system that improves effluent quality and allows for water reuse. By characterizing influents and effluents, seven important parameters were identified for treatment optimization. The results showed that using combustion gases and new flocculant-coagulant reagents improved various parameters. The obtained effluent quality allowed for reuse in pre-dyeing stages without impacting the final quality of cotton fabrics. This effort has the potential to save water and supplies, as well as improve the environmental conditions of the region.

Summary: Water scarcity is a major global challenge impacting food safety, food security, and human health. This study explored the potential of using vertical flow constructed wetlands (VF-CWs) with different indigenous wetland plants to treat chromium (Cr)-contaminated water. The results showed that VF-CWs vegetated with certain wetland plants can effectively remove Cr from water, with removal rates ranging from 47% to 92%. The wetland plants also accumulated Cr, with higher concentrations found in the roots. This research provides evidence supporting the use of VF-CWs with indigenous wetland plants as a sustainable technology for treating Cr-contaminated water.

Summary: The performance of different macrophytes in floating treatment wetlands (FTWs) for the remediation of ciprofloxacin (CIP) contaminated water is investigated in this study. The FTWs have the potential to remove 30-43.58 mg L-1 CIP from water in 28 days, and also reduce the chemical oxygen demand and biochemical oxygen demand of water. Among the macrophytes, Canna indica is the most effective in removing CIP, while Typha domingensis is the least effective. This study contributes to the sustainable bioremediation of water contaminated with antibiotics.

Summary: This study investigated the distribution, speciation, hydrogeochemical behavior and environmental risks of chromium in tannery wastewater in Kasur district, Punjab, Pakistan. The concentration of chromium was higher in winter compared to summer, and exceeded the national environmental quality standard. The presence of chromium was mainly in the form of hexavalent and trivalent chromium, controlled by iron and magnesium minerals. Environmental risk assessment categorized the tannery wastewater as 'worst quality' and unsuitable for crop irrigation without treatment.

Summary: The objective of this study was to screen for aminoacidopathies in patients suspected of having inborn errors of metabolism. Abnormal amino acid profiles, particularly in glutamic acid, ornithine, and methionine levels, were found in some patients through biochemical analysis of samples. Advanced biochemical and genetic analyses confirmed these diseases and treatment could be offered to these patients, reducing the burden of intellectual disability caused by rare metabolic diseases in the target populations.
