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...

The SDP (semidefinite programming) relaxation for general POPs (polynomial optimization problems), which was proposed as a method for computing global optimal solutions of POPs by Lasserre, has become an active research subject recently. We propose a new heuristic method exploiting the equality constraints in a given POP, and strengthen the SDP relaxation so as to achieve faster convergence to ...

BACKGROUND Research suggests that estrogenic endocrine-disrupting chemicals interfere with lactation. OBJECTIVES (1) to determine if estrogenic persistent organic pollutants (POPs) are associated with shortened lactation duration; (2) to determine whether previous breastfeeding history biases associations. METHODS AND RESULTS We measured selected organochlorines and polychlorinated biphenyl...

The behavior of cholesterol is different in mixtures with phosphatidylcholine as compared with phosphatidylserine. In (13)C cross polarization/magic angle spinning nuclear magnetic resonance spectra, resonance peaks of the vinylic carbons of cholesterol are a doublet in samples containing 0.3 or 0.5 mol fraction cholesterol with 1-palmitoyl-2-oleoyl phosphatidylserine (POPS) or in cholesterol m...

The natural reservoir for influenza A virus (IAV) is wild aquatic birds, where the virus transmits usuallywith low-pathogenicity to the hosts. However, these viruses can spillover into other animals, includingmarine mammals and humans, with devastating consequences: causing outbreaks and in some casesmass mortalities. Marine mammals, at the top of their food chains, are highly conta...

liver samples from golden jackal (canis aureus) were collected from noor in the central coastline mazandaran province. the samples of this study were killed in road accidents. levels of persistent organochlorine pollutants (pops) including polychlorinated biphenyls (pcbs), ddts and metabolites, hexachlorocyclohexanes (hchs) and metabolites, hexachlorobenzene (hcb), aldrin and dieldrin were meas...

Persistent organic pollutants (POPs) are long-lived environmental contaminants that are widely detected in humans. Elevated circulating levels of POPs have been linked to hypertension, obesity, diabetes, meta bolic syndrome, and myocardial infarction in humans. Atherosclerosis, characterized by lipid-rich plaques on the inner wall (intima) of the artery, also can lead to myocardial infarction a...

Understanding and quantifying the global dynamics and sinks of persistent organic pollutants (POPs) is important to assess their environmental impact and fate. Air-surface exchange processes, where temperature plays a central role in controlling volatilization and deposition, are of key importance in controlling global POP dynamics. The present study is an assessment of the role of oceanic biog...

The presence of toxic substances such as persistent organic pollutants (POPs) in the environment, and in organisms including humans, is a serious public health and environmental problem, even at low levels and poses a challenging scientific problem. The Stockholm Convention on POPs (SC) entered into force in 2004 and is a large international effort under the United Nations Environment Programme...
