The northern aplomado falcon (Falco femoralis septentrionalis) disappeared from south Texas in the 1940s. Due to great success in the release of captive-reared aplomado falcons in south Texas, there are currently more than 40 established nesting pairs in the region. Addled eggs from aplomado falcons nesting in northern Chihuahua and south Texas were analyzed to determine organochlorine (OC) and...

Surface water and sediment samples collected from Jukskei River in South Africa, were subjected to different extraction techniques, liquid-liquid (LLE), solid-phase extraction (SPE), activated carbon extraction (ACE) and soxhlet extraction (SE) for sediment. The samples were extracted with dichloromethane, cleaned in a silica gel column and the extracts quantified using a Varian 3800 GC-ECD. Th...

Dichlorodiphenyltrichloroethane (DDT) is a pesticide that was commonly used for decades worldwide. The use of DDT banned in the 1970s and 1980s Europe because its high toxicity persistence environment, bioaccumulation living organisms biomagnification through food webs. However, monitoring using both invasive non-invasive methods has routinely reported occurrence metabolites such as dichlorodip...

We highlight shortcomings of the dynamical dark energy (DDE) paradigm. For parametric models with an equation state, $w(z)={w}_{0}+{w}_{a}f(z)$, for a given function redshift $f(z)$, we show that errors in ${w}_{a}$ are sensitive to $f(z)$: if $f(z)$ increases quickly $z$, then smaller, and vice versa. As result, DDE suffer from degree arbitrariness, focusing too much on one model runs risk may...

Studies conduc ted by o thers have revealed that 1 ,1 -d ich lo ro2 ,2 -b i s (p -ch lo ropheny l )e thy lene (DDE), a proximal metabol i te of d ich lo rod ipheny l t r i ch lo roe thane (DDT), is a st rong hepatocel lu lar ca rc inogen in mice. Since hamsters appear to be resistant to tumor induct ion by DDT, we wanted to invest igate whe the r DDE has any neoplast ic ef fect in this species....

In-utero exposure to endocrine-disrupting compounds, including dichlorodiphenyltrichloroethane (DDT) and its metabolite dichlorodiphenylethylene (DDE), has been hypothesized to increase the risk of obesity later in life. We examined the associations of maternal serum concentrations of DDT and DDE during pregnancy with body mass index, obesity, waist circumference, and percentage of body fat in ...

We examined plasma dichlorodiphenyldichloroethene (DDE) and total polychlorinated biphenyl (PCB) levels in relation to breast cancer in a population-based, case-control study of African-American women (292 cases and 270 controls) and white women (456 cases and 389 controls) in North Carolina. Adjusted odds ratios (ORs) for breast cancer comparing the highest to lowest third of DDE were 1.41 [95...

The organochlorines, dichloro-diphenyl-trichloroethane and polychlorinated biphenyl (PCB) are pervasive environmental contaminants. Results from previous studies have been conflicting regarding the relationship between the internal dose of these organochlorine residues and breast cancer risk. To determine whether these compounds are present in breast cyst fluids and whether cyst fluid and plasm...

The present study was designed to evaluate associations between developmental defects of enamel (DDE) in the primary dentition and aspects related to mothers and preschoolers in the city of Diamantina, Brazil. A case-control study was carried out involving children aged three to five years. The case group was composed of 104 children with at least one dental surface affected by DDE. The control...
