Persistent Organic Chemicals In The Environment. Volume 1244 Dec 2016

Persistent Organic Chemicals In The Environment. Volume 1244

Bommanna Loganathan

Topics covered in Volume 2 include lessons learned from three decades monitoring contaminants in Pacific Basin wildlife samples from the USA’s Marine Environmental Specimen Bank (Chapter 1); spatial and temporal trends of brominated flame retardants (Chapter 2), PCBs, pesticides, and dioxins/furans, in the environment and biota in the USA, Colombia (Chapter 3), China (Chapter 4), Korea (Chapter 5), and Japan (Chapter 6 and Chapter 7); emission of emerging pharmaceutical contaminants in the USA (Chapter 8) and Vietnam (Chapter 10); and possible application of bio-analytical assays in the biological impact assessment of persistent organic pollutants in Mangrove sediments in Southeast Asia …


Persistent Organic Chemicals In The Pacific Basin Countries: An Overview, Bommanna Loganathan 8093044 Dec 2016

Persistent Organic Chemicals In The Pacific Basin Countries: An Overview, Bommanna Loganathan 8093044

Bommanna Loganathan

The Pacific Basin is a unique geographical region representing tropical, temperate and polar zones. This region is home to 2/3 of world’s population and consists of rapidly growing economies (countries) and highly developed countries. The Pacific Basin countries have had a history of use of persistent organic chemicals (POCs) at varying proportions during the last five decades. Due to diverse climatic and socio-economic conditions, the environment and biota in different countries in this basin have varying degrees of environmental contamination and effects on wildlife and humans. In this chapter, the historical background of POCs including, discovery, production, use,
regulations/restrictions imposed, …


Organohalogen Contaminants In Sediment And Fish Samples From Riverine And Estuarine Waters Of Savannah, Georgia, Usa, Dylan Benningfield, Joseph P. Richardson, Bommanna G. Loganathan, Kenneth S. Sajwan Dec 2016

Organohalogen Contaminants In Sediment And Fish Samples From Riverine And Estuarine Waters Of Savannah, Georgia, Usa, Dylan Benningfield, Joseph P. Richardson, Bommanna G. Loganathan, Kenneth S. Sajwan

Classical and emerging persistent organic pollutants are of great concern due their negative effects on the environment, wildlife and human health. Estuaries and coastal marine environments are considered the most sensitive areas to the accumulation of these pollutants. The objective of this study was to understand the contamination status of classical and emerging pollutants in the rivers and estuarine waters of Savannah, Georgia. PCB congeners, chlorinated pesticides and PBDEs were analyzed in sediment and various fish species samples collected from the Vernon River, and other estuarine/brackish waters in the region. Standard analytical procedures were followed to determine the concentrations of …


E-Waste And Associated Environmental Contamination In The Asia/Pacific Region (Part 2): A Case Study Of Dioxins And Furans In E-Waste Recycling/Dump Sites In India, Paromita Chakraborty, Sakthivel Selvaraj, Masafumi Nakamura, Balasubramanian Prithiviraj, Shunkei Ko, Bommanna G. Loganathan Dec 2016

Hazardous persistent organic pollutants including polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) associated with informal electronic waste (e-waste) recycling process is an emerging environmental problem in India. Hence we took the first attempt to measure the toxic equivalents (TEQ) of dioxins and furans in surface soil and passive air samples collected from informal e-waste recycling facilities and open dumpsites in India by using Chemically Activated Luciferase Expression (CALUX) bioassay. CALUX TEQs for PCDD/Fs was measured in the informal e-waste recycling sites engaged in crude process of extracting precious metals and compared with the CALUX TEQs from the open dumpsites from three major …

An increasing demand for electronic equipment and the rapid growth of the electronic industry has resulted in the production of large amounts of electronic waste (e-waste), including obsolete computers, cellular phones, televisions etc. Transboundary movement of disposed e-waste in developing countries for recycling and extraction of precious metals in crude manner is of severe environmental and human health concern. In spite of a global ban through the Basel Convention, during the past two decades several countries in the Asia Pacific region are involved in recycling e-waste scrap mostly by informal or crude methods. China, India and Pakistan were major importers …


Environmental Emission Of Pharmaceuticals From Wastewater Treatment Plants In The Usa, Bikram Subedi, Bommanna Loganathan 8093044 Nov 2016

Environmental Emission Of Pharmaceuticals From Wastewater Treatment Plants In The Usa, Bikram Subedi, Bommanna Loganathan 8093044

The residual drugs, drug bioconjugates, and their metabolites, mostly from human and veterinary usage, are routinely flushed down the drain, and enter wastewater treatment plants (WWTP). Increasing population, excessive use of allopathic medicine, continual introduction of novel drugs, and existing inefficient wastewater treatment processes result in the discharge of large volumes of pharmaceuticals and their metabolites from the WWTPs into the environment. The effluent from the WWTPs globally contaminate ~25% of rivers and the lakes. Pharmaceuticals in the environment, as contaminants of emerging concerns, behave as pseudo-persistent despite their relatively short environmental half-lives in the environment. Therefore, residual levels of …
