Plastic is one of the most abundant pollutants in environment. As a result natural physical processes, large plastic waste degraded into microsized particles (<5 mm) called microplastics. Because their size, abundance, and durability, microplastics are widely distributed environment, contaminating food water intended for human consumption. The extent microplastic contamination body still unclear because there few studies concerning specimens and, studies, data were collected from city...

Abstract Red mud is an industrial waste generated from the alumina production process which has increased every year. This hazardous because it a high pH and contains heavy metals, one of scandium (Sc). Scandium rare metal that widely used in various industries, so economic value. Phytomining innovative technology utilizes plants to extract metals contaminated soil or waste. research aims determine ability Chrysopogon zizanioides absorb red using domestic sludge as planting medium...

Abstract Red mud, a by-product of the Bayer process in aluminum production, contains significant quantities heavy metals, including scandium. However, its high alkalinity limits bioavailability these metals for plant uptake. This study aims to enhance scandium availability red mud by modifying pH and electrical conductivity (EC) through addition cow dung manure, thereby improving uptake plants. samples were treated with 10% manure mixture reduce EC. Changes pH, EC, availability, monitored...
