Preface

Endocrine-disrupting chemicals (EDCs) represent a heterogeneous group of exogenous chemicals that interfere with the action of hormones. Their number has markedly increased over the past 60 years. EDCs may be significant components of the environmental origin of several medical conditions. The coronavirus disease 2019 (COVID-19) pandemic has affected human health around the world. Several endocrine and metabolic systems can be impacted by COVID-19. This book examines the impacts of EDCs and the COVID-19 pandemic on human health, including endocrine and metabolic consequences.

The book contains six chapters by authors from France, India, Spain, and the United States. I would like to thank all of them. I would also like to thank the great assistance of Ms. Romina Rovan at IntechOpen who supervised this book project.
