Chapter1: Atmospheric electrical conductivity measurements during monsoon period at a semi-urban tropical station of Northern India -- Chapter2: Temporal mount in air pollutants allied with religious fiesta: DIWALI, festival of lights -- Chapter3: Mushrooms: as biological tool in Mycoremediation for soil pollution -- Chapter4: Establishing correlation between abiotic stress and isoprene emission of selected plant species -- Chapter5:Microplastic an unsafe pathway from Aquatic Environment to Health: A Review -- Chapter6: A review on the dairy industry wastewater characteristics, its impact on environment and treatment possibilities -- Chapter7: Physico – chemical Treatment of Research Laboratory Wastewater – A Case Study -- Chapter8: Efficiency of various granular activated carbon adsorbents in the treatment of waste water generated from Research & Development Laboratory-A case study.This book consists of full research papers submitted by scientists/faculty/research scholars who attended the conference on "Earth and Environment: Pollution and Prevention" held at Amity University, Noida from January 28-30, 2014 and had their abstracts published in the conference proceedings. The selected contributions mainly address contemporary issues related to environmental contamination such as industrial wastewater characterization and treatment, microplastics, temporal mount of air pollutants, atmospheric EC, ecofriendly catalytic technology for textile waste, dairy industry, waste water treatment, industrial air pollution, and plant isoprene emissions. The eight studies in the book will be of interest to environmental pollution researchers and students, as well as scientists interested in the proceedings from the" Earth and Environment: Pollution and Prevention" meeting. .
