OBJECTIVE Recent epidemiological studies have shown that background exposure to persistent organic pollutants (POPs)--xenobiotics accumulated in adipose tissue--is strongly associated with type 2 diabetes. Hyperglycemia is the cause of long-term complications of diabetes as well as diabetes itself, and POPs are well-known neurotoxicants. This study was performed to explore whether POPs are asso...

Persistent organochlorine residues in the environment are a threat to ecological health of aquatic organisms and pose risk both animals human consumers. Organochlorine pesticides were determined water sediments collected during wet dry season from selected riverine earthen fish pond sites high altitude catchment areas within Kuja River (Kenya) between August 2016–May, 2017. Analysis DDT metabol...

Organic pesticides were developed during and after World War II to displaced inorganic and metal organic substances such as sulfur, arsenic, sodium fluoride and boric acid, which used by society for thousands of year. Some of these pesticides were OCPs which are organic compounds that contain chlorine. These OCPs were preferred because of their effective against the target pests even if only sm...

BACKGROUND Endometriosis is considered an estrogen-dependent disease. Persistent environmental chemicals that exhibit hormonal properties, such as organochlorine pesticides (OCPs), may affect endometriosis risk. OBJECTIVE We investigated endometriosis risk in relation to environmental exposure to OCPs. METHODS We conducted the present analyses using data from the Women's Risk of Endometrios...

BACKGROUND Few human studies have evaluated the impact of childhood exposure to organochlorine pesticides (OCP) on pubertal development. OBJECTIVE We evaluated associations of serum OCP concentrations [hexachlorobenzene (HCB), β-hexachlorocyclohexane (βHCH), and p,p-dichlorodiphenyldichloroethylene (p,p´-DDE)] with age at attainment of sexual maturity among boys. METHODS From 2003 through 2...

Abstract The major nesting sites for the endangered green turtle ( Chelonia mydas ) are in Campeche, Mexico: Carmen, Isla Aguada, and Sabancuy. Although they a natural reserve, these threatened by agricultural activities oil extraction. This study aimed to determine presence concentration of organochlorine pesticides (OCPs) polycyclic aromatic hydrocarbons (PAHs) plasma eggs assess antioxidant ...

High mountains may play significant roles in the global transport of persistent organic pollutants (POPs). This work aims to investigate the levels, patterns and distribution of semi-volatile organochlorine pollutants and to improve the understanding of the long-range atmospheric transport and fate of contaminants on the Tibetan Plateau. A total of 60 fish samples were collected from eight lake...

Organochlorine pesticides have been used in Mexico in malaria control programs and against ectoparasites. The objective of this study was to compare the levels of organochlorine pesticides: HCB, α-β-γ-HCH, pp'-DDE, op'-DDT and pp'-DDT in adipose tissue of female inhabitants from three Mexican states: Veracruz, Puebla and Tabasco. Data analyses indicated higher β-HCH levels in Puebla inhabitants...

The residue levels of 16 US EPA priority polycyclic aromatic hydrocarbons (PAHs) and 16 selected organochlorine pesticides (OCPs) in rice and rice hull collected from a typical e-waste recycling area in southeast China were investigated from 2005 to 2007. PAHs and OCPs also were measured in ten mollusk species (soft tissues) collected in an adjacent bay in 2007. Individual PAHs were frequently ...
