Microplastics (MPs) are ubiquitous pollutants in various environmental matrices. In this study, 82 road dust samples collected from Myanmar and Taiwan between 2014 2018 were analyzed to investigate the status of MPs pollution distribution. Myanmar, mean abundances high cities, such as Nay Pyi Taw (285 pieces/kg dry weight), Mandalay (79 pieces/kg), Yangon (63 pieces/kg). Alternatively, no found...

Recent efforts worldwide have resulted in a growing database of measured concentrations of chemicals in blood and urine samples taken from the general population. However, few tools exist to assist in the interpretation of the measured values in a health risk context. Biomonitoring Equivalents (BEs) are defined as the concentration or range of concentrations of a chemical or its metabolite in a...

Phthalates are a group of multifunctional chemicals used in consumer and personal care products, plastics, and medical devices. Laboratory studies show that some phthalates are reproductive and developmental toxicants. Recently, human studies have shown measurable levels of several phthalates in most of the U.S. general population. Despite their widespread use and the consistent toxicologic dat...

BACKGROUND Phthalates are synthetic compounds with a widespread field of applications. For example, they are used as plasticizers in PVC plastics and food packaging, or are added to personal care products. Diethyl phthalate (DEP) may be used to denature alcohol, e.g., for cosmetic purposes. Public health concerns of phthalates include carcinogenic, teratogenic, hepatotoxic and endocrine effects...

This article reviews laboratory and epidemiological research into the endocrine disruptive effects of components of personal care products, namely, phthalate esters, parabens, ultraviolet (UV) filters, polycyclic musks, and antimicrobials. High doses of phthalates in utero can produce “phthalate syndrome,” demasculinizing effects in male rat offspring due to impaired testosterone ...

The pollution status and characteristics of PAEs (phthalate esters) were investigated in indoor air of offices, and PAEs of both gas-phase and particulate-phase were detected in all the samples. The concentration (sum of the gas phase and the particulate phase) was 4748.24 ng/m3, ranging between 3070.09 and 6700.14 ng/m3. Diethyl phthalate, dibutyl phthalate, and di(2-ethylhexyl) phthalate were...

Worldwide, anthropogenic contaminants emerge and enter into aquatic systems; their ubiquity in aquatic systems poses serious threats to both human health and ecological systems. As the demand for water continues to grow with population, treatment of wastewater and remediation of polluted aquatic systems are of critical concern. Ozonation and advanced oxidation processes (AOPs) are promising met...

Interest has been expressed in tracing possible sources of contamination (e.g. from human or other waste) by using compounds such as pharmaceuticals, caffeine, and sterols in waste as potential source markers. This pilot study was designed to identify and measure a limited set of compounds in aqueous environmental samples to determine possible relations between these compounds to animal and hum...

Phthalate plasticizers and heavy metals are widely recognized to be pollutants that interfere with key developmental processes such as masculinization. We investigated the release of phthalates and heavy metals in coffee brewed from coffee packed in single-serve coffee containers made from different types of materials: metal, biodegradable and plastics. We detected with GC-MS small amounts phth...
