    Artificial intelligence in heavy metals detection: Methodological and ethical challenges
    (Elsevier B.V., 2023-07-02T00:00:00) Yadav, Nidhi; Maurya, Brij Mohan; Chettri, Dewan; Pooja; Pulwani, Chirag; Jajula, Mahesh; kanda, Savleen Singh; babu, Harysh Winster Suresh; Elangovan, Ajay; Velusamy, Parthasarathy; Iyer, Mahalaxmi; Vellingiri, Balachandar
    Heavy metals (HMs) are metallic substances. They enter biotic and abiotic systems through natural and human activities. These HMs have an impact on the atmosphere, soil, and groundwater, and they also affect all living things, especially humans, when they enter the food chain. Therefore, monitoring and removing HMs from the environment and humans are crucial for maintaining HMs-based toxicity. The detection of HMs from environmental and human samples has been performed by techniques such as atomic adsorption spectrometry (AAS) and inductively coupled plasma mass spectrometry (ICP-MS). With the advancement of AI-based technology, HMs are now detected and removed from the environment and human systems. This review discusses the impact of HMs on the environment and human health, their detection and removal techniques, and the integration of recent advancements in AI-based technology for the detection and removal of HMs from environmental and human samples. � 2023 The Author(s)

    Biodegradable Plastics: New Challenges and Possibilities toward Green Sustainable Development
    (wiley, 2022-03-18T00:00:00) Kumar, Rabindra; Razdan, Sumeer
    In the past few decades, several research studies have reported the adverse impact of conventional plastics on the environment and human health. Conventional plastics contain a mixture of known and unknown harmful materials or chemicals that are unsafe for human health and pose disposal challenges as they are not degraded easily in nature. Thus, there has been a dire need to develop and introduce bio�based and biodegradable plastics as an alternative source over conventional plastic. For manufacturing and development of bio�based and biodegradable plastics, focus on the use of raw materials and chemicals which are green and clean with respect to nature are needed; which includes proteins, carbohydrates, polysaccharides, and eco�friendly constituents with environment�friendly physicochemical properties from various natural sources. In recent year, the reports of biodegradable plastics such as poly(e�caprolactone) (PCL), poly(lactic acid) (PLA), poly(3�hydroxybutyrate) (PHB), polyethylene (Bio�PE), polyhydroxyalkanoates (PHA), poly(butylene succinate) (PBS), and bamboo�based materials have come into prominence rather than conventional materials for the commercial purpose. This chapter focuses on better alternatives of natural raw materials for the manufacturing and development of biodegradable plastics, which are eco�friendly in nature and safe for human use. � 2022 John Wiley & Sons Ltd.
