The rapid expansion of both the global economy and human population has led to a shortage water resources suitable for direct consumption. As result, remediation will inexorably become primary focus on scale. Microalgae can be grown in various types wastewaters (WW). They have high potential remove contaminants from effluents industries urban areas. This review focuses recent advances WW through microalgae cultivation. Attention already been paid microalgae-based wastewater treatment (WWT) due its low energy requirements, strong ability thrive under diverse environmental conditions, transform nutrients into high-value compounds. It turned out that WWT is an economical sustainable solution. Moreover, different toxins are removed by biosorption, bioaccumulation, biodegradation processes. Examples agricultural runoffs textile pharmaceutical industrial effluents. mitigate carbon dioxide make use micronutrients present paper highlights application pollutants commonly mechanisms, simultaneous resource recovery, efficient co-culturing systems along with bottlenecks prospects.

Toxicity of Heavy Metals and Recent Advances in Their Removal: A Review

Toxics, Journal Year: 2023, Volume and Issue: 11(7), P. 580 - 580

Published: July 3, 2023

Natural and anthropogenic sources of metals in the ecosystem are perpetually increasing; consequently, heavy metal (HM) accumulation has become a major environmental concern. Human exposure to HMs increased dramatically due industrial activities 20th century. Mercury, arsenic lead, chrome, cadmium have been most prevalent that caused human toxicity. Poisonings can be acute or chronic following via water, air, food. The bioaccumulation these results variety toxic effects on various tissues organs. Comparing mechanisms action reveals induce toxicity similar pathways, including production reactive oxygen species, inactivation enzymes, oxidative stress. conventional techniques employed for elimination deemed inadequate when HM concentration is less than 100 mg/L. In addition, methods exhibit certain limitations, secondary pollutants, high demand energy chemicals, reduced cost-effectiveness. As result, employment microbial bioremediation purpose detoxification emerged as viable solution, given microorganisms, fungi bacteria, superior biosorption bio-accumulation capabilities. This review deals with uptake associated HMs, will increase our knowledge their body organs, leading better management poisoning. aims enhance comprehension offer judicious selection remediation technology HMs. Microbial-based solutions sustainable could potentially crucial cost-effective reducing

Use of dyes as well colorants in industrial processes has extensively increased. Effluents from various industries such textile, paint, food, etc. are reported to have a diverse range colorants. The effluents these often released into natural water bodies, causing serious and environmental pollution, which humans other species constantly exposed. Continued changes climate also affected availability for people around the world. Thus, advanced treatments removal harmful contaminants municipal wastewater becoming increasingly important. Removal can be done variety ways, including physical, chemical, biological treatments. These technologies, however, differ terms efficiency, cost, effect. There many technological economic challenges treatment methods currently available. search most suitable strategy successful degradation or is an urgent requirement. Previously published research suggests that use enzymes dye more effective compared traditional techniques. Nanoparticles, with their exceptional physicochemical features, potential tackle problem purification less energy-intensive way. However, extensive standardization would necessity different nanoparticles. Therefore, intense nanoparticle-based technologies may provide much needed solution remediation wastewater.
