“…Once produced, these chemicals remain in our ecosystem for several years and continue to exert their harmful effect on human health in the form of diseases like cancer, birth defects, and neurological and immunological disorders (El-Shahawi et al 2010 ). Certain POPs are associated with immunodeficiency in infants, while a few others are substantial risk factors for breast cancer (Toms et al 2016 ; Mouly and Toms 2016 ). Brain development in infants may get affected due to exposure to POPs, as it has been shown that children exposed to POPs during infancy scored comparatively lower in intelligence and concentration measurements (Tran and Miyake 2017 ).…”

Air pollution is a serious threat to our health and has become one of the major causes of many diseases including cardiovascular disease, respiratory disease, and cancer. The association between air pollution and various diseases has long been a topic of research interest. However, it remains unclear how air pollution actually impacts health by modulating several important cellular functions. Recently, some evidence has emerged about air pollution-induced epigenetic changes, which are linked with the etiology of various human diseases. Among several epigenetic modifications, DNA methylation represents the most prominent epigenetic alteration underlying the air pollution-induced pathogenic mechanism. Several other types of epigenetic changes, such as histone modifications, miRNA, and non-coding RNA expression, have also been found to have been linked with air pollution. Hypersensitivity pneumonitis (HP), one of the most prevalent forms of interstitial lung diseases (ILDs), is triggered by the inhalation of certain organic and inorganic substances. HP is characterized by inflammation in the tissues around the lungs’ airways and may lead to irreversible lung scarring over time. This review, in addition to other diseases, attempts to understand whether certain pollutants influence HP development through such epigenetic modifications.

“…While comparisons must be made with caution due to small sample sizes and different geographical locations, this does indicate a 10 fold decrease for BDE-47 in household dust which may influence exposure via indoor environments. Assessment of PBDEs in baby foods in Australia in 2015 suggests a decrease in concentration from a previous time point of 2004 but again, comparisons must be made with caution due to small sample sizes (Toms et al 2016). Children born in the most recent time periods appear to have lower environmental exposures than those born early in the monitoring period.…”

In Australia, systematic biomonitoring of persistent organic pollutants (POPs) in pooled serum samples stratified by age and sex has occurred every two years between 2002/03 and 2012/13. Multiple regression modeling on log10-transformed serum pool concentrations of BDEs 47, 99, 100 and 153 and on the sum of these (ΣPBDE) was conducted to examine trends by sex and time since baseline, stratified by age group. Temporal trends were age- and congener-specific, with the largest changes per year of observation in the 0-4 year old group, with β (SE) = -0.098 (0.013) for logBDE47; -0.119 (0.012) for logBDE99; -0.084 (0.014) for logBDE100, and -0.053 (0.013) for logBDE153, all p < 0.001. Adults over age 16 showed much smaller decreasing temporal trends for BDE47 and BDE99, no significant changes in BDE100, and, for the oldest age groups, slight increases in BDE153. As a result, ΣPBDE concentrations were stable over the entire time period in adults older than 16. Concentrations of each BDE in pools from females aged 31-60 were significantly lower compared to males. Relative proportions of BDE47 declined, while BDE153 accounted for a greater share of ΣPBDE over time. Whereas previously we saw a large elevation in the youngest age groups compared to older children and adults, this is no longer the case. This may be due to a decline in infant and toddler exposures in the indoor environment as use of PBDEs in consumer products has been phased out, suggesting temporal changes in the relative sources of exposure for young children in Australia.

“…Among the 41 targeted compounds, 19 compounds were detected in at least one of the 46 samples (LOQ; 0.005 to 0.02 ng/g-w.w.) (Table 2, Table S2). HCB was most frequently detected (78%), followed by p,p'-DDE (65%), and TC (57%) ( Some reports have discussed the dietary intakes of organohalogenated compounds in baby food from the US and China (Liu et al, 2014), Australia (Toms et al, 2016), Korea (Jeong et al, 2014a;Jeong et al, 2014b) and Spain (Lorán et al, 2010). These studies were not based on 24-h duplicate-diet, but rather on an individual ingredient or commercial-, homemade-baby food.…”
