Impact of Water Pollution & Perspective Techniques to Mitigate It
AI summary Read the abstract
This review covers the major sources of water pollution, including agricultural runoff, industrial waste, and microplastic contamination, and their effects on aquatic life and human health. Researchers evaluated modern treatment technologies like membrane bioreactors and advanced filtration that offer improvements over conventional methods. The study highlights the need for more efficient, eco-friendly, and cost-effective water treatment approaches.
Surface water pollution has a major role in degrading the water bodies in all aspects, including physical, chemical, and biological. An increase in usage of chemical fertilizers, pesticides, disposal of harmful waste chemicals from industries, and dumping of different inorganic waste ultimately increases the level of chemicals in the water bodies, thus resulting in greater damage to the aquatic life. Plastic waste, especially microplastic pollution, is also one of the major concerns for marine pollution. When dissolved in water, this microplastic releases harmful toxic chemicals that are lethal to flora and fauna. There are many drawbacks of these conventional treatment techniques, including high cost, space requirement, power usage, time-consuming method, and non-specific for certain pollutants, which will decrease the efficiency rate. The release of chemicals and heavy metals like cadmium, lead, and mercury accumulates in the waterbodies and affects not only aquatic life but also human health and the environment. To overcome this problem, various advanced techniques like activated sludge, rapid sand filtering, membrane bioreactor, etc., are used to remove the pollutants from the water bodies. This review focuses on the modern techniques that are found to be more efficient, eco-friendly, consume less energy, and are more reliable.

The Occurrence of Micropollutants in the Aquatic Environment and Technologies for Their Removal
AI summary Read the abstract
This review summarizes the growing problem of micropollutants in water, including microplastics, pharmaceuticals, and industrial chemicals, and evaluates advanced treatment methods to remove them. The research is important for human health because conventional water treatment plants cannot effectively filter out these contaminants, meaning people may be regularly exposed through tap water.

Microplastics in Urban Runoff and Wastewater: Sources, Transport, and Advanced Removal Technologies
AI summary Read the abstract
This research review found that tiny plastic particles called microplastics are getting into our water systems through city runoff and sewage, coming from sources like car tire wear, synthetic clothing, and construction materials. While current water treatment plants can remove many of these plastic particles, a significant amount still escapes into rivers, lakes, and other water bodies that could eventually reach our drinking water. The study highlights that we need better water treatment technology and monitoring to protect our water supply from this growing plastic pollution problem.
