Preface

Trace elements have always been an interesting area of research, as the human body contains a large number of trace elements that fully control enzymes and hormone production. This book examines the useful as well as harmful effects of trace elements on both humans and the environment. It includes seven chapters divided into two sections. Section 1, "Trace Elements in Biology," includes chapters on the effects of trace elements on breast cancer, respiratory diseases, tissue impairment, and iron-related diseases. Section 2, "Trace Elements in Environmental Problems" includes chapters that focus on environmental issues, such as urban particulate matter and trace elements in medicinal plants.

This book is a useful resource for students and researchers involved with human health and diseases. I hope this book provides useful information for carrying out novel research in this field.
