“…As expected, the concentrations of p,p′-DDE found in delivering women from São Paulo State are lower than those found in Mexican and South African delivering women residing in areas where DDT is used to control malaria vector. In contrast, the levels of p,p′-DDE were found to be much higher in delivering women in our study if compared with recent similar studies performed in Vietnam and elsewhere Röllin et al, 2009;Waliszewski et al, 2000).…”

“…Levels of PCB congeners found in the current study are comparable to those measured in the general population in other non-industrialised developing countries such as Tanzania and India, but lower than those recently reported from Guinea-Bissau and from industrialised countries in the North (Anda et al, 2008;Linderholm et al, 2010;Todaka et al, 2010;Weiss et al, 2006). Interestingly, PCB levels in Brazilian delivering women were higher than those recently reported in the plasma of delivering women in South Africa and Vietnam Röllin et al, 2009). They were however lower than those reported by Van Oostdam et al (2004) in comparable populations residing in Canada, the Netherland and Spain.…”

2012Levels of selected persistent organic pollutants in blood from delivering women in seven selected areas of Sao Paulo State, Brazil ENVIRONMENT INTERNATIONAL, OXFORD, v. 40, Persistent organic pollutants (POPs) present in the living environment are thought to have detrimental health effects on the population, with pregnant women and the developing foetus being at highest risk. We report on the levels of selected POPs in maternal blood of 155 delivering women residing in seven regions within the São Paulo State, Brazil. The following selected POPs were measured in the maternal whole blood: 12 polychlorinated biphenyls (PCBs) congeners (IUPAC Nos. 99, 101, 118, 138, 153, 156, 163, 170, 180, 183, 187, 194); dichlordiphenyltrichloroethane p,p′-DDT, diphenyldichloroethylene p,p′-DDE and other pesticides such as hexachlorocyclohexanes (α-HCH, β-HCH, γ-HCH), hexachlorobenzene (HCB), chlordane derivatives cis-chlordane, transchlordane, oxy-chlordane, cis-nonachlor and trans-nonachlor. Statistical comparisons between regions were performed only on compounds having concentrations above LOD in 70% of the samples. PCB118 congener was found to be highest in the industrial site (mean 4.97 ng/g lipids); PCB138 congener concentration was highest in the Urban 3 site (mean 4.27 ng/g lipids) and congener PCB153 was highest in the industrial and Urban 3 sites with mean concentration of 7.2 ng/g lipids and 5.89 ng/g lipids respectively. Large differences in levels of p,p′-DDE between regions were observed with the Urban 3 and industrial sites having the highest concentrations of 645 ng/g lipids and 417 ng/g lipids, respectively; β-HCH was found to be highest in the Rural 1 site; the γ-HCH in Rural 1 and industrial; the HCB in the Rural 1 and industrial sites and oxy-chlordane and t-NC in the Rural 2 sites. An association between levels of some contaminants and maternal age and parity was also found.

Organochlorine pesticides for whatever length of time that been extensively utilized as a part of farming and in public health as highly effective pest control agents.They are lipophelic and have drawn out a half-existences of years to decades; thus, they amass in human fat tessues and a can bring about endless poisonous quality after long term exposure.To detect and measure the concentrations of organochlorine pesticides, (Dieldrin and Heptachlor) in serum and fatty tissue samples and studies their correlation with lipids in order to reveal the need. for human monitoring.The study was conducted on 50 samples of blood and fatty tissues to determine their lipid concentrations and detect metabolites of organochlorine pesticides and asses their1correlations using HPLC.The study observed that there were raised serum concentrations of lipids which were positively corresponded with lifted serum convergences of Dieldrin and Heptachlor pesticides.Mean serum concentrations of triglycerides was inside "normal" range while mean serum of aggregate cholesterol was hoisted above ordinary range. Rate of grouping of lipid to serum Dieldrin was higher than that of Heptachlor in living subjects.

“…The Arctic Monitoring and Assessment Programme (AMAP) started in 1991 and currently all Arctic countries are members, namely: Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and USA [9–12]. Countries located in tropical and southern areas have joined more recently, including South Africa [8,13], Brazil [6,14], Vietnam [15] and Australia [16,17]. The extent of human exposure, as measured by biological contaminant concentrations, has not been adequately investigated in South America.…”

Several ongoing international multidisciplinary projects have examined linkages between environmental chemicals and health. In contrast to Arctic regions, information for the Southern Hemisphere is scarce. Because of the inherent practice of pesticide utilisation and mismanagement, food security is potentially threatened. The most vulnerable period in human life occurs during pregnancy and early childhood, thus a focus on the body burdens of PTS in pregnant or delivering women is warranted. The current study was designed to investigate health risks related to exposure to PTS and food security in two regions of Argentina (Ushuaia and Salta). Our aims were to quantify concentrations of organic and inorganic toxins in serum or whole blood of delivering women and to collect pertinent dietary and medical information. The overall study design, the basic demographic features and essential clinical chemistry findings are described in the current paper. The socioeconomic differences between the two study areas were evident. On average, the women in Ushuaia were 4 years older than those in Salta (28.8 vs. 24.7 years). Respectively, the proportion of current smokers was 4.5 vs. 9.6%; and Salta had a higher birth rate, with 15.6% being para four or more. Saltanean women reported longer breastfeeding periods. Caesarean sections were more frequent in Ushuaia, with 43% of Caesarean deliveries compared with only 6% in Salta. Employment was high in both communities. Recognised environmental pollution sources in the vicinity of participant dwellings were widespread in Salta (56.1%) compared to Ushuaia (9%). The use of pesticides for insect control in homes was most common in Salta (80%). There is an urgent need for a comprehensive assessment of exposures in areas of the Southern Hemisphere. Our data set and the planned publications of observed concentrations of inorganic and organic environmental contaminants in both mothers and their newborns will contribute to this objective.
