Advances in Environmental Research: Volume 50

This book provides readers with the latest developments in environmental research. Chapter One is an exertion providing up-to date information on mass concentration levels, sources, different types of particles associated with particulate matter (PM) and their effects on human health, climate and natural environment along with controlling methods. Chapter Two evaluates the impact of the foliar applications of seaweed extract (SWE) obtained from Ulva rigida species on salt stress tolerance in wheat plants (Triticum durum L.). Chapter Three addresses polychlorinated biphenyl (PCB) origins, uptake dinamics, biotransformation, bioaccumulation and documented impacts over these marine animals, approaching a 'state of knowledge and setting an integrated basis for future tiered studies to estimate the actual human exposure risk through seafood consumption and giving support for future conservational measures. Chapter Four uses the Delphi method, analytical hierarchy process (AHP) and fuzzy logic theory to establish a system of multi-criteria decision making (MCDM) to illustrate the influence of community resident participation on the effectiveness of sustainable green community development. Chapter Five reviews an empirical analysis on the factors influencing energy efficient residential renovations in Taiwan by using the Delphi method, analytical hierarchy process, and utility theory. Chapter Six focuses on dental caries, enamel hypoplasia and dental wear, which were observed in the populations of the Syrian lower Euphrates valley representing six cultures dated from the Early Bronze Age to the modern Islamic period. Chapter Seven discusses perfluoroalkylation of organic compounds by photoredox catalysis with organic dyes.
