This article presents a systematic literature review (SLR) aimed at identifying existing studies, prevailing methodological approaches, and regional gaps in the academic investigation of ELMs. A total of 12 articles were analyzed, with findings indicating a strong concentration of research in Asian countries, mainly employing quantitative and technical methodologies. These studies focus primarily on environmental impacts and logistical improvements but lack broader analyses incorporating regulatory, institutional, and behavioral dimensions. The review also highlights a critical absence of research in America Latina and Africa, regions where the motorcycle fleet is rapidly expanding. This gap underscores the urgent need for context-specific studies that address solid waste management challenges, predict future waste generation, and explore opportunities for urban mining and circular economy strategies.

The adsorption behavior of NaP zeolite is examined in both single-ion and competitive adsorption systems, considering variables like pH, contact time, ion concentration, and adsorbent dosage. The results indicate that NaP zeolite is highly effective in removing Cr(VI) under acidic conditions, while it efficiently adsorbs Cd(II) and Pb(II) in neutral to alkaline environments. In competitive systems, ion interactions are influenced by properties such as speciation, hydrated radius, and hydration enthalpy.

This study investigated the pre-monsoon water quality and water quality index (WQI) of Markanda and Ghaggar rivers, focusing on the physico-chemical analysis and the environmental impact of drain water mixing into the river. Samples of water were drawn from upstream and downstream, and from points where drains were mixed into the river. The findings indicate severe water degradation in the drains and downstream areas. High biological oxygen demand (BOD) (190 mg/L) and chemical oxygen demand (COD) (640 mg/L) indicate very high loads of organic pollution. Increased total dissolved solids (TDS) (3682 mg/L) and total suspended solids (TSS) indicate higher salinity, which is less suitable for irrigation and drinking purposes.

The chloride levels also exceeded the permissible limit, indicating anthropogenic effects. The upstream water quality ranged from fair to excellent, with physico-chemical parameters within acceptable limits for aquatic life and agricultural use. The downstream values of WQI ranged from poor to very poor after the drain water mixing. The Gibbs diagram used to perform hydrochemical analysis indicates that the anthropogenic activity is the leading contributor to the control of water chemistry and not the natural geochemical processes.
