Different exposure profile of heavy metal and health risk between residents near a Pb-Zn mine and a Mn mine in Huayuan county, South China

Heavy metal contamination of environmental media in mining area is a global major concern because of its potential threat for human health through food chain. However, the comparison of exposure level and health risk is scarce among people living in the vicinity of mining area with different pollution source. In this study, the concentrations of [read more]

Profiles, variability, and predictors of urinary benzotriazoles and benzothiazoles in pregnant women from Wuhan, China

Benzotriazoles (BTRs) and benzthiazoles (BTHs) are emerging contaminants with high production volume worldwide, which exhibit potential health risk to human. To date, little is known about the exposure of BTRs and BTHs (BTs) on human, especially in the context of pregnancy. In the present study, the authors aimed to characterise the exposure profiles, temporal variability, [read more]

Overview of known plastic packaging-associated chemicals and their hazards

Global plastics production has reached 380 million metric tons in 2015, with around 40% used for packaging. Plastic packaging is diverse and made of multiple polymers and numerous additives, along with other components, such as adhesives or coatings. Further, packaging can contain residues from substances used during manufacturing, such as solvents, along with non-intentionally added [read more]

Domestic Exposures to Polycyclic Aromatic Hydrocarbons in a Houston, Texas, Environmental Justice Neighbourhood

Polycyclic aromatic hydrocarbons (PAHs) are a class of >100 chemicals that naturally occur in coal tar, crude oil, and gasoline and can be manufactured as part of dyes, plastics, and pesticides. PAHs are complex environmental toxicants and exposure to them have been linked to adverse health outcomes including cancer, as well as diseases of the [read more]

Outdoor air pollution pregnancy exposures are associated with behavioural problems in China’s pre-schoolers

There are mounting evidences indicated that maternal exposure to outdoor air pollutants in pregnancy affects children’s neural development, but the researches on children’s behavioural difficulties are seldom. In the present study, the authors explored the association between maternal exposure to outdoor air pollution during different trimesters of pregnancy and the prevalence of behavioural difficulties among [read more]

Surgical smoke: still an underestimated health hazard in the operating theatre

Smoke generated from electrocautery dissection contains irritating and/or carcinogenic components. The aim of this study was to investigate the effectiveness of a mobile smoke evacuation system (SES) in protecting surgical personnel from these hazardous fumes. Standardised cuts with an electrocautery device were performed on fresh porcine tissue, and the generated surgical fume was analysed with [read more]

Monitoring early cell damage in physicians who are occupationally exposed to inhalational anaesthetics

Worldwide, millions of professionals who work in operating rooms are occupationally exposed to inhalational anaesthetics. Thus, the potential health effects of the continuous exposure to inhalational anaesthetics on individuals in the operating room remain a subject of debate. Human biomonitoring is a potentially useful tool for assessing the health of exposed professionals. No report has [read more]

Occupational manganese exposure, reproductive hormones, and semen quality in male workers: A cross-sectional study

It has been found that exposure to manganese (Mn) could induce reproductive dysfunction, but its occupational risk in male workers is unclear. This study aims to assess the association of occupational Mn exposure with reproductive hormones and semen quality in a cross-sectional study. Urinary Mn, semen quality, and reproductive hormones were explored in 84 male [read more]

The reproducibility of urinary ions in manganese exposed workers

Manganese (Mn) is found in environmental and occupational settings, and can cause cognitive and motor impairment. Existing Mn exposure studies have not reached consensus on a valid and reproducible biomarker for Mn exposure. Previously, global metabolomics data was generated from urine collected in October 2014 using mass spectrometry (MS). Nine ions were found to be [read more]

Colorimetric Detection of Carcinogenic Alkylating Fumigants on Nylon-6 Nanofibrous Membrane. Part I: Investigation of 4-( p-Nitrobenzyl) Pyridine as A “New” Sensing Agent with Ultra-High Sensitivity.

Alkylating fumigants are widely used in agricultural production for the control of soil-borne pests, but the acute toxicity and carcinogenicity of these chemicals pose a health threat to farm workers as well as residents. A nanofibrous membrane-based colorimetric sensor relying on the nucleophilic substitution reaction of 4-(p-nitrobenzyl) pyridine (NBP) is introduced for the convenient and [read more]
