The book presents a new EIA (Environmental Impact Assessment) model for Pakistan. Two important parameters i.e. urban air pollution caused by motor vehicles and wastewater effluents caused by industrial sector in the country, are the focus of this work. The strategy presented in this book will improve the EIA process and help to prevent further environmental degradation caused by developmental activities in Pakistan on all levels. The book is intended as a guide for the engineers in industry, governmental agencies and consulting engineering firms involved in the day-to-day application of EIA, and as a text for the students in courses related to environmental engineering, planning, management and EIA at undergraduate and postgraduate level.
