Toxic element exposure increases risk of neurodevelopmental disorders. However, hair element profiles of well-nourished urban resident children were largely unknown. We identified prevalence and the contributing factors of high hair aluminum (Al), arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) levels in 111 Thai children (aged 3-7 years old). Most participants were well-nourished with high socioeconomic status. Since ROC curve of hair element data showed inadequate sensitivity for cutoff set-up, US reference hair levels were used to categorize high and low level groups...

Electronic cigarettes (ECs) are essentially nicotine delivery devices that mimic the appearance of a conventional cigarette (CC). Lately, they have been marketed as tools for quitting smoking. Even though they are promoted as safe alternatives to CC, they are not devoid of hazardous components. Literature reveals that the EC aerosols and e-liquids are a potential source of elements that induce and promote development of chronic conditions. These include trace metals which are leached from their core assembly...

Heavy metals have harmful effects on health of both ecosystems and organisms to their accumulation ability. Copper (Cu) is an essential element for organism survival, but EPA considers Cu as a priority pollutant. On the other hand, boron has well-defined biological effects in living organisms including cytoprotection and genoprotection, although borax (BX) metabolism is poorly described in fish. Moreover, the effects of boron supplementation against Cu-induced hematotoxicity and DNA damage in aquatic organisms are still undetermined...
