Questo libro un tentativo di valutare la tossicit di alcuni pesticidi sulla sopravvivenza di due piante galleggianti. Azolla cristata e Salvinia natans. Nell'era odierna, i pesticidi e gli insetticidi finiscono per entrare negli ecosistemi acquatici, costituendo una minaccia per la sopravvivenza delle varie specie vegetali e animali che abitano questi sistemi. Questo libro servir come guida di base ai ricercatori e agli studenti per comprendere la tossicit delle sostanze chimiche pi diffuse sulla diversit e sulla sopravvivenza delle piante.

Dieses Buch ist ein Versuch, die Toxizit t bestimmter Pestizide auf das berleben von zwei frei schwimmenden Pflanzen zu bewerten. Azolla cristata und Salvinia natans. In der heutigen Zeit finden Pestizide und Insektizide ihren Weg in die aquatischen kosysteme und stellen somit eine Bedrohung f r das berleben der verschiedenen Pflanzen- und Tierarten dar, die diese Systeme bewohnen. Dieses Buch soll Forschern und Studenten als grundlegender Leitfaden f r das Verst ndnis der Toxizit t der weit verbreiteten Chemikalien auf die Pflanzenvielfalt und das berleben dienen.

Ce livre est une tentative d' valuation de la toxicit de certains pesticides sur la survie de deux plantes flottantes. Azolla cristata et Salvinia natans. De nos jours, les pesticides et les insecticides finissent par se retrouver dans les cosyst mes aquatiques, ce qui constitue une menace pour la survie des diverses esp ces v g tales et animales qui peuplent ces syst mes. Ce livre servira de guide de base aux chercheurs et aux tudiants pour comprendre la toxicit des produits chimiques largement r pandus sur la diversit et la survie des plantes.

Este livro uma tentativa de avaliar a toxicidade de certos pesticidas sobre a sobreviv ncia de duas plantas flutuantes livres. Azolla cristata e Salvinia natans. Na era actual, os pesticidas e insecticidas acabam por encontrar o seu caminho para os ecossistemas aqu ticos, representando assim uma amea a sobreviv ncia das v rias esp cies vegetais e animais que habitam estes sistemas. Este livro servir como guia b sico para os investigadores e estudantes na compreens o da toxicidade dos amplamente qu micos sobre a diversidade e sobreviv ncia das plantas.

This book is an attempt towards assessing the toxicity of certain pesticides on the survival of two free floating plants. Azolla cristata and Salvinia natans. In today's era pesticides and insecticides are ultimately finding their way into the aquatic ecosystems, hence posing a threat to the survival of the various plant and animal species inhabiting these systems. This book shall serve as basic guide to the researchers and students in understanding the toxicity of the widely chemicals on the plant diversity and survival.

Climate change and global warming resulting in unusual patterns of temperature and precipitation are widely recognized as the most significant environmental dilemma today. In this backdrop an attempt has been made to identify the trends of temperature and precipitation in Srinagar based on data from 1987-2014. The book shall serve as a useful resource for understanding the dynamics of temperature and precipitation in the era of global climate change. The book is a resource for understanding the impact of the changing climate on fragile ecosystems as well as help gain an insight into the future trends of temperature and precipitation in the temperate Himalayan ecosystems.

This book highlights the importance of ground water because knowing the groundwater level is important for several reasons, including understanding aquifer levels under static conditions and pumping conditions, determining how the levels interact with local surface water sources, and understanding how surface development has impacted the aquifer. Ground water pollution is more complicated than surface water pollution because the contaminated aquifer is very much difficult to treat and recover as compared to surface water body. This book provides an insight into the effect of change in physico-chemical parameters of water on human health. Dental fluorosis, methamoglobinaemia, Knock-Knee Syndrome are some typical diseases associated with ground water pollution. This book can be a very helpful tool for students and scholars to understand the groundwater dynamics and effect of ground water pollution on human heath described with examples and case studies.
