    Environmental Friendly Technologies for Remediation of Toxic Heavy Metals: Pragmatic Approaches for Environmental Management
    (Springer International Publishing, 2022-05-06T00:00:00) Sharma, Ritika; Saini, Khem Chand; Rajput, Sneh; Kumar, Mohit; Mehariya, Sanjeet; Karthikeyan, Obulisamy Parthiba; Bast, Felix
    Contamination of different environmental matrices (air, soil, and water) by toxic heavy metals is a widespread problem that disturbs the environment as an outcome of many anthropocentric practices. Heavy metals exceeding the permissible limits exert deleterious impacts on human beings, causing life-threatening health manifestations and detrimental effects on the environment. This has alarmed the dire need to explore various modern remediation techniques that can be utilized to lower excessive concentrations. Owing to their high-cost effectiveness, unsatisfactory output, environmentally unfriendly, complicated procedure, and high operational costs, these technologies failed to find any practical utility in remediation. On the other hand, plants and associated microorganisms are receiving more consideration as a means of remediating or degrading environmental pollutants. This chapter provides us insights into the various environmental friendly techniques that will improve our environment�s quality. Among which, phytoremediation is considered an effective technique which is known for its esthetic benefits and endless applicability. Furthermore, metal-resistant bacteria (plant growth-promoting rhizobacteria) are also reported to play a pivotal role in the phytoremediation and solubilization of minerals. Thus, this chapter critically reviews the phytoremediation technology and the efficient exploitation of microbes to alleviate the environmental burden of toxic heavy metals. � The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

    Evaluation of genotoxic potential of gropundwater from industrial and farmering sites on colon cancer cell lines
    (Central University of Punjab, 2014) Kaur, Rimplejeet; Kumar, Sanjeev
    Water is critical component on earth which is essential for life. There are number of reservoirs of water like surface water, groundwater etc. used for drinking, domestic as well as industrial purposes. Numerous studies have shown that water is contaminated by many pollutants like chemicals including pesticides, fertilizers, and heavy metals including arsenic, uranium, and exposure to this contaminated water may cause number of health problems including cancer. It has been found that in Punjab, specifically Malwa region's groundwater is highly contaminated by pesticides and heavy metals which may correlate to several health problems in this region. In this context, mechanisms of genotoxic potential activity of the groundwater, from thermal plant and villages Deon and Joganand, was estimated in the present study. The groundwater caused reactive oxygen species production, mitochondrial membrane depolarization, which ultimately caused cell death. Groundwater also affected the antioxidant system enzymes, so all these factors may be the cause of health problems in this region.
