This Book will be a very helpful tool to understand the Blood Lead Levels and its relation with various biochemical activities of Humans in general and children in particular. Widespread use of Pb has caused extensive environmental contamination and health problems in many parts of the world. Lead is a cumulative toxicant that affects multiple body systems, including the neurological, hematological, gastrointestinal, cardiovascular and renal systems. Acute exposures may cause gastrointestinal disturbances (anorexia, nausea, vomiting, abdominal pain), hepatic and renal damage, hypertension and neurological effects (malaise, drowsiness, encephalopathy) that may lead to convulsions and death while chronic exposure commonly causes haematological effects, such as anaemia, or neurological disturbances, including headache, irritability, lethargy, convulsions, muscle weakness, ataxia, tremors and paralysis. So with the help of practical case studies, this book is an attempt to understand various effects of BLL in the development, survival and growth of children. For young scientists, this book will be good means to understand the biochemistry of Pb in children and its detrimental effects.

This book provides a detailed information about the importance of lentic water bodies. It highlights the role played by these natural resources in maintaining the ecological balance on the surface of earth. Due to anthropogenic pressure and unsustainable development, these fragile ecosystems have become the dump sites of various toxic pollutants like chemical fertilizer residues, heavy metals, pesticides and other xenobiotic agrochemicals. This book provides a kind of awareness regarding the current status of these urban lakes and recommends some of the important strategies for their management and safeguard. This book also throughs light on the mineral status of agricultural soils in two geographically different districts of Kashmir so as to understand the change in soil quality due to unsustainable agricultural practices. This book is a useful tool for students and scholars to understand the current status of some culturally important water bodies in Himalayan range and their future perspectives.

The study is done on the basis of primary and secondary surveys and both lakes are urban with different geographical and environmental conditions, as the study and observations suggest that the condition of water and sediments of both lakes has extremely deteriorated from last two decades. Our research, observation, and readings are from only four months due to lack of time and accessibility, as our study and collection of samples are latest. This is from, January and February for Dal Lake, and March and April for Bellandur lake Bangalore. Which are giving the details of water quality of both lakes and the investigations are showing the increasing trend in pollution of both lakes. This study will be beneficial for the respective departments of both lakes whether it is LAWDA (lakes and waterways development authority) Jammu and Kashmir and LDA (lakes development authority) Bangalore Karnataka and for further future researches on both lakes these parameters will give a brief introduction on physico chemical characteristics of both lakes. Due to lack of time and infrastructure our study was limited and little but qualitative in producing information.
