Persistent organic pollutants (POPs) are organic compounds of natural or
anthropogenic origin that resist photolytic, chemical and biological
degradation. They are characterized by low water solubility and high
lipid solubility, resulting in bioaccumulation in fatty tissues of
living organisms. These properties of unusual high persistence and
semi-volatility, coupled with other characteristics, have resulted in
the presence of POPs all over the world, even in regions where they have
never been used. With the evidence of long-range transport of these
substances to regions, the international community has now, at several
occasions called for urgent global actions to reduce and eliminate
releases of these chemicals. Many countries have already banned or
severely restricted the production and use of the twelve POPs in recent
decades. Yet they remain a serious problem around the world. Because
these chemicals have the ability to travel long distances from their
original sources, relying on national-level action alone is ultimately a
futile effort.
This book employs a science-based approach to identify and take action
against POPs, and additionally, provides access to technical information
on POPs. The book will be an overview of the existing POP monitoring
activities and programs.
