(MPs), perchlorate (ClO4-), which are the representatives of different diverse
regions across the globe starting from Southeast Asia, East Asia to South Asia. In
the first chapter, the authors have critically evaluated and analyzed the anthropogenic biomarkers in Asian groundwater based on 23 studies conducted in six
countries (China, India, Japan, Korea, Singapore and Vietnam) to report the
community level toxic effects of such biomarkers under different climatic conditions. The second chapter emphasizes the importance of different fundamental/
advanced biomolecular techniques (affinity- based chromatography) for the analysis
of emerging contaminants in wastewater and the environment. This chapter highlights the importance of different binding agents such as antibodies, molecularly
imprinted polymers, and chiral stationary phases with the bioanalytical derivatives
like macrocyclic antibiotics, proteins and polysaccharide to have more insight on
biological separation events. Chapters in this part provide an overview of various
natural attenuation processes for CECs, with specific attention to aqueous photochemistry of pharmaceuticals, evaluated using laboratory-scale and on-site observations. Collectively, this part highlights natural attenuation for specific classes of
pharmaceuticals and focused on the governing mechanisms -underlying such
attenuation processes based on studies conducted worldwide. This part is also
helpful in characterizing the various physico-chemical processes through which
MPs enter into the river ecosystems and the fate of the plastic particles in aquatic
environments. Moreover, the eco-toxicological effect of MPs towards the aquatic
biota, their detection techniques and possible risk management have also been
discussed to establish their abundance and to develop possible mitigation strategies
to reduce human health hazard. The authors of the fifth chapter have summarized
water quality analysis on a total of 1262 groundwater wells distributed all over the
country (Sri Lanka) for the determination18 water quality parameters using multivariate statistical analysis techniques. Cluster analysis was used to classify the
groundwater wells based on their quality. The purpose of the study is to increase the
viability of water recourse management and protection in Sri Lanka by providing
statistical analysis result for the entire country. This part also depicts the combined
biological/physico-chemical processes such as natural biodegradation, phytoremediation, bioreactor, chemical reduction, adsorption, membrane filtration, ion
exchange, electrochemical reduction etc. for the adsorptive removal of ClO 4- by
iron nanoparticles, catalytic reactors etc. Among physical, chemical and biological
ClO 4- removal methods, biological treatment is considered as the cheapest and
eco-friendly technology. The final chapter of this part elucidates carcinogenic and
human health properties of emerging contaminants such as nanoparticle and
specific PPCPs. Arsenic, radon, hazardous waste, agricultural chemical, fluoride,
etc. are discussed in detail focussing on their role in various types of cancer such as
lungs, breast, kidney, bladder, liver etc. These kinds of critical discussions are
needed to find economical ways to treat contaminated wastewater in order to reduce
risk of cancer.
The eleven chapters in the second part reflect the multifaceted application of
biological processes (bioreactor, anammox etc.), abiotic degradation (photo catalysis, ozonation, etc.), natural removal (constructed wetland), and granular sludge
