“…The remaining DDT metabolites were not found above limits of detection. The 4,4′-DDE and 4,4′-DDT concentrations found in the present study were much lower than those reported in venous maternal blood or cord blood serum of Shanghai and Huaihe River Basin (China; Zhang et al, 2018;Luo et al, 2016;Cao et al, 2011), Crete (Vafeiadi et al, 2014), Michalovce and Svidnik (Slovakia; Park et al, 2008), Algarve (Lopes et al, 2014), Rio Grande do Sul (Mohr et al, 2015), Menorca (Carrizo et al, 2006), Granada (Mariscal-Arcas et al, 2010), Valencia (Vizcaíno et al, 2010), Ribera d'Ebre (Sala et al, 2001) and Antwerp (Covaci et al, 2002). In contrast, they were higher than those from cohorts in Ushuaia (Bravo et al, (Bergonzi et al, 2009), the average European Union (Govarts et al, 2012) and Canadian Northwest Territories and Nunavut areas (Butler Walker et al, 2003) (Table 3).…”

“…Multiparity was associated with decreased maternal serum concentrations of o,p ′-DDT. These results are similar to other studies that have also revealed that parity is negatively associated with maternal serum concentrations of some POPs [ 23 , 30 ] due to the fact that these compounds are permeable through the placenta and are transferred to the growing foetus [ 18 , 29 , 31 , 32 , 33 ]. Thus, a negative association between p,p ′-DDT and parity is attributed to mother-to-foetus transfer of these compounds through the placenta.…”

Population exposure to persistent organic pollutants (POPs) may result in detrimental health effects, especially to pregnant women, developing foetuses and young children. We are reporting the findings of a cross-sectional study of 605 mothers in their late pregnancy, recruited between August 2020 and July 2021 in southern Malawi, and their offspring. The aim was to measure the concentrations of selected POPs in their maternal serum and indicate associations with social demographic characteristics and birth outcomes. A high level of education was the main predictor of p,p′-DDE (p = 0.008), p,p′-DDT (p < 0.001), cis-NC (p = 0.014), o,p′-DDT (p = 0.019) and o,p′-DDE (p = 0.019) concentrations in maternal serum. Multiparity was negatively associated with o,p′-DDE (p = 0.021) concentrations. Maternal age was also positively associated (p,p′-DDE (p = 0.013), o,p′-DDT (p = 0.017) and o,p′-DDE (p = 0.045) concentrations. Living in rural areas was inversely associated with high maternal serum concentrations of p,p′-DDT (p < 0.001). Gestational age was positively associated with p,p′-DDE (p = 0.031), p,p′-DDT (p = 0.010) and o,p′-DDT (p = 0.022) concentrations. Lastly, an inverse association was observed between head circumference and t-NC (p = 0.044), Oxychlordane (p = 0.01) and cis-NC (p = 0.048). These results highlight the need to continue monitoring levels of POPs among vulnerable populations in the southern hemisphere.

“…Methoxychlor is an alternative for p,p′-DDT and had been increasingly used from the 1970s (Oh, 2009) until being banned in Europe (2002) and the United States (2003) (Neves et al, 2018). However, methoxychlor can still be detected in some provinces of China, southeastern Asia, and South Africa (Luo et al, 2016;Neves et al, 2018;Zeng et al, 2018). Methoxychlor has been well studied in snow, ice core, air, freshwater, and biota bodies but rarely in seawater (Hoferkamp et al, 2010).…”

Spatial Distributions and Seasonal Changes of Current‐Use Pesticides from the North Pacific to the Arctic Oceans

et al. 2019

Distributions of eight targeted current‐use pesticides (CUPs) chloroneb, simazine, atrazine, alachlor, dacthal, chlorobenzilate, methoxychlor, and permethrin were investigated in seawater and the atmosphere in a region covering the North Pacific to the Arctic Oceans during the 7th and 8th Chinese National Arctic Research Expedition (2016 and 2017) voyages of the research vessel R/V Xuelong (Snow Dragon in English). Total CUP concentrations in seawater have prominent seasonal and latitudinal trends, with higher concentrations occurring at lower latitudes in early summer. The major contributors of the CUPs (∑8CUP) did not alter over different seasons with dominant chloroneb, alachlor, and atrazine accounting for more than 90%, but their concentrations did have marked seasonal changes. However, the compositions of the eight analyzed CUPs varied indistinctly between seasons indicating a possible combined environmental impact on these compounds rather than the effects of individual chemical properties. Three‐day backward air mass trajectories indicate that atmospheric masses from northeastern China are responsible for the high concentrations of CUPs in East China and Japan Seas, whereas those from the North Atlantic Ocean contribute to the low levels in local area. Fugacity ratios indicate potential volatilization and equilibrium of chloroneb in the Canada Basin of the Arctic Ocean and Japan Sea, respectively, and deposition of other CUPs in both regions. However, atmospheric concentrations are decoupled from those in seawater, which indicates a low exchange rate.
