“…However, in this population 401 concentrations of 4,4'-DDT and 4,4'-DDD were higher among multiparae than 402 primiparae women (n = 33; Tsydenova et al, 2007). In contrast, higher concentrations 403 of 4,4'-DDE and ∑DDT have been observed in primiparae than multiparae women fromwere found in primiparae than multiparae women and the differences were statistically 408 significant.…”

However, the observed increases were not uniform and in some individuals high values 59 (5100 ng/g lipid) were determined. Significant differences were found between the 60 concentrations of DDT and related compounds in breast milk according to parity, with 61 higher concentrations in primiparae than multiparae women. These differences 62 overcome the age effect in DDT accumulation between the two groups and evidence 63 that women transfer a significant proportion of their body burden of DDT and its 64 metabolites to their infants. 65 66 67 68

“…The concentrations of PCOCs were significantly and positively associated with maternal age and it can be attributed to the accumulation of PCOCs in adipose tissues. [13][14][15] However, in the case of multipara, the concentrations were not correlated with age. 14,16) Because the accumulated PCOCs are eliminated by the excretion in breast milk, the concentrations decrease with the total lactation periods.…”

Human milk is an important food source for infant because it contains a large number of nutritional substances, growth and immune factors. However, human milk may be contaminated with environmental pollutants when mothers are exposed to these pollutants. In particular, lipophilic organic pollutants are likely to accumulate in milk fat. Therefore, the determination of the organic pollutants levels in human milk is necessary to estimate the health risks of these pollutants to milk-fed infants. For this purpose, a lot of reports for the measurements of environmental pollutants in milk samples have been published. In this review, we summarized the concentrations of harmful organic environmental pollutants such as polychlorinated organic compounds (PCOCs), polybrominated compounds, perfluorinated compounds (PFCs), polycyclic aromatic hydrocarbons (PAHs) and endocrine disrupting phenols in human milk samples. Also, we described the noteworthy results of several evaluative studies such as time trend and regional difference of pollutant levels.

“…Liquid-liquid extraction (LLE) is one of the conventional methods still being used for the extraction of such pesticides from various matrices [9] [10]. Also, solid-phase extraction (SPE) [11]- [17], supercritical fluid extraction (SFE) [18], and matrix solid-phase dispersion (MSPD) [19] is the other more selective approach in this field. Generally, these methods are multistage, expensive, laborious, and consume long time as well as; in these methods, a large amount of organic solvents are applied to extract the analysts of interest [20].…”

In this study, headspace solid phase microextraction (HS-SPME) followed by gas chromatography using electron capture detection system (GC-ECD) were developed for the determination of chloraacetanilide (butachlor) and chlorpyrifos presented in biological samples. Different parameters affecting the extraction procedure were optimized including extraction time (30 minutes), extraction temperature (80˚C), sample volume (3 mL), sample pH (2), added NaCl (0.3 gram) and sample stirring rate (400 rpm). Different concentrations of 1 -100 ng/ml were applied for butachlor and a linear calibration curve was obtained. Furthermore, a similar linearity was obtained for chlorpyrifos, using a concentration range of 1 -250 ng/ml. The limit of detection (LOD) obtained for butachlor and chlorpyrifos were 0.088 and 0.53 ng/ml respectively. The optimized methods for both compounds were validated using two concentrations of 25 and 50 ng/ml in spiked urine samples. Obtained recoveries of spiked urine samples were 83.06% -99.8% with RSD of lower than 11%. Optimized technique was simple, inexpensive, solvent free and fast in comparison with other conventional methods and had compatibility with the chromatographic analytical system. This method offers low detection limits to analyze pesticides in urine samples that are very important * Corresponding author. F.
