“…In any case, it should be noted that these comparisons are not totally reliable since in these papers a different number of compounds were included, with 15 analytes in the works of Hong Kong and China and 50 individual PAHs in the work of Texas. However, if we compare only the values of the most toxic PAHs (PAH7) with those reported in the literature, we found that levels of this study were much lower than those described in China (Yu et al 2011;Guo et al 2012;Song et al 2013) and Hong Kong (Tsang et al 2011).…”

“…Many POPs come from the production and use of organochlorine compounds, such as organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs). Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants containing two or more fused benzene rings that are produced during the incomplete combustion of organic matter and during human or industrial activities (Guo et al 2012). Because of their efficient metabolization, strictly speaking, PAHs cannot be considered as POPs, but due to their high prevalence in the environment and their lipophilicity, PAHs are usually considered as POPs (Lammel et al 2013).…”

Several studies have shown that pet dogs and cats, since they share the habitat with people, could be good sentinels for human exposure to environmental pollutants. However, some publications have suggested that dogs could efficiently metabolize and eliminate some persistent organic pollutants (POPs), which are accumulated by humans throughout life. For this reason, the role of domestic dogs as sentinels could not be appropriate, at least for certain contaminants. To test this hypothesis, we designed this study in which we determined plasma levels of 56 POPs (11 organochlorine pesticides [OCPs], 18 polychlorinated biphenyls [PCBs] and 27 polycyclic aromatic hydrocarbons) in the plasma of 87 dogs and 100 people from the same area (the Canary Islands, Spain). We detected most of these contaminants in the plasma of both species, although the frequencies of detection, concentrations and profiles were very different from each other, especially for ∑OCPs and ∑PCBs. In light of these results, we can conclude that, although they share the environment, sources of exposure to these pollutants and/or the metabolic capabilities do not seem to be comparable between the two species, so that the dog does not seem to be a good sentinel for human exposure to these contaminants.

“…Our previous studies demonstrated that heavy metals and organic pollutants from e-waste were associated with stillbirth, premature delivery, and anencephaly, and the neonatal Apgar score, height, and weight were lower than those of children from the reference area [29][30][31][32][33]. Growth hormones, such as placental insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP-3) from an e-waste-exposed area, were higher than those from the reference group.…”

The adverse effects of electronic waste (e-waste) on the human body have stirred up concern in recent years. China is one of the countries that confront serious pollution and human exposure of e-waste, and the majority of the population is exposed to potentially hazardous substances that are derived from informal e-waste recycling processes. This study reviews recent reports on human exposure to e-waste in China, with particular focus on exposure routes (e.g., inhalation and ingestion) and several toxicities of human (e.g., endocrine system, respiratory system, reproductive system, developmental toxicity, neurotoxicity, and genetic toxicity). Pieces of evidence that associate e-waste exposure with human health effects in China are assessed. The role of toxic heavy metals (e.g., lead, cadmium, chromium, mercury, and nickel) and organic pollutants (e.g., polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyl (PCBs), polycyclic aromatic hydrocarbons (PAHs), polybrominated biphenyls (PBBs), polyhalogenated aromatic hydrocarbons (PHAHs), bisphenol A (BPA)) on human health is also briefly discussed.

“…It is a rice-growing countryside and its industry has been dominated by e-waste recycling since the early 1980s. Eighty percent of families in Guiyu are engaged with individual recycling workshops, with nearly 160,000 workers involved in recycling activities but without protective measures Wu et al, 2010;Liu et al, 2011;Wu et al, 2011;Guo et al, 2012;Wu et al, 2012). The area has a sub-tropical climate, with an annual average temperature of 21.5°C, relative humidity of 80% and mean annual rainfall of 1721 mm (Deng et al, 2006;Wong et al, 2007b).…”

In this study, we characterized the concentration of heavy metals in PM 2.5 in the community with e-waste dismantling, Guiyu, China and assessed potential public health risk associated with heavy metal composition of PM 2.5 for local residents. Daily samples of PM 2.5 were collected with Harvard Impactors on the roof of 3-story buildings from March 2012-April 2013 in Guiyu (n = 133) and seasonal samples were collected in a reference site, Haojiang (n = 33). The concentrations of PM 2.5 mass and heavy metals were analyzed gravimetrically and by graphite furnace atomic absorption spectrometry, respectively. The geometric mean concentrations of PM 2.5 , Pb and Cd in Guiyu were higher than in the reference area (PM 2.5 : 49.9 µg m -3 vs. 37.6 , p < 0.01; Pb: 160 ng m -3 vs. 69 ng m vs. 16 ng m -3 , p > 0.05). The metal concentrations in PM 2.5 from Guiyu were also higher when compared to other Asian cities. We observed higher heavy metal concentrations during winter and spring than summer and fall. Human health risk assessment showed that the total potential cancer risk for both adults and children are higher than the safe acceptable range recommended by the US EPA. Furthermore, the carcinogenic and non-carcinogenic elements in PM 2.5 pose higher public health risk to children than adults. The results indicate that air pollution emitted from informal e-waste recycling activities might be affecting the health of local residents, especially children.
