The need for capacity building and first results for the Stockholm Convention Global Monitoring Plan
The Stockholm Convention on Persistent Organic Pollutants (POPs) established an effectiveness evaluation to assess the efficiency of measures taken by Parties under the Convention. Among these measures, a Global Monitoring Plan requires countries to analyze core matrices for POPs. To assist countries in setting up networks for these core matrices and to generate high-quality, comparable results...
It is not a point of debate that the Stockholm Convention for the prevention of further accumulation of persistent organic pollutants (POPs) should be ratified and implemented by all countries. However, in their article, Schafer and Kegley present an unbalanced "worst case scenario". Approximately 20% of the food supply of the US is contaminated with POPs at extremely low levels; these levels a...
Many international efforts have been spent to eliminate and/or reduce the emissions and discharges of a wide range of pollutants that have persisted in the environment as well as living organisms [1]. These pollutants are known as a persistent organic pollutants (POPs). Contamination from POPs is a pervasive global problem that urgently demands a global solution [2]. These chemicals include org...
BACKGROUND The incidence of the insulin resistance syndrome has increased at an alarming rate worldwide, creating a serious challenge to public health care in the 21st century. Recently, epidemiological studies have associated the prevalence of type 2 diabetes with elevated body burdens of persistent organic pollutants (POPs). However, experimental evidence demonstrating a causal link between P...
BACKGROUND Fish are a source of persistent organic pollutants (POPs) in the human diet. Although species, trophic level, and means of production are typically considered in predicting fish pollutant load, and thus recommendations of consumption, capture location is usually not accounted for. OBJECTIVES Yellowfin tuna (Thunnus albacares) are harvested from across the world's oceans and are wid...
Chlorinated organic compounds, prevalent contaminants found in the geo-environment, pose an ecological risk even at trace concentrations. More volatile chlorinated compounds such as VOCs (volatile organic compounds) have been detected in urban areas and industrial zones because of the use of these compounds as components of industrial solvents and both raw and intermediate synthetic products. C...
During the past two decades, the rapid development of the Pearl River delta leads to substantial accumulation of various toxic organic compounds. This study aims to give a preliminary characterization of the existing state of contamination in this region and to provide insight into the possible fate of persistent organic pollutants (POPs) in this estuary. The available data on POPs in water, ri...
Worldwide there is concern about the continuing release of persistent organic pollutants (POPs) into the environment. In this study we review the application of mosses as biomonitors of atmospheric deposition of POPs. Examples in the literature show that mosses are suitable organisms to monitor spatial patterns and temporal trends of atmospheric concentrations or deposition of POPs. These examp...
Studies suggest that environmental exposure to persistent organic pollutants (POPs) may be an emerging risk factor for ischemic heart disease, including acute myocardial infarction (AMI). However, some studies indicate that exposure to POPs may also be a risk factor for hypertension, a well-established risk factor for AMI. To investigate effect of POPs on the environmental burden of cardiovascu...
OBJECTIVE Polychlorinated biphenyls (PCBs) and polychlorinated dibenzofurans (PCDFs) are important and persistent organic pollutants (POPs) in humans. Recent cross-sectional studies have detected increased concentrations of serum POPs in diabetic patients. We aimed to examine the association between previous high exposures to PCBs and PCDFs and the cumulative incidence of type 2 diabetes and hy...
