Consumer products are significant contributors to indoor volatile organic compound (VOC) emissions, with oil‐based wood stains, commonly used in do‐it‐yourself (DIY) projects, being particularly notable sources. This study was aimed at evaluating personal exposure to VOCs during DIY application of oil‐based wood stains by integrating passive sampling, dermal exposure assessment, and urinary biomonitoring. Twenty‐two volunteers wore a validated expanded polytetrafluoroethylene passive sampler (eP

Objectives:The purpose of this study is to provide basic data for the development of a rapid and easy to measure alternative indicator for estimating the number of cyanobacteria cells in the field.Methods:Phycocyanin, algal cell number, and water quality items were measured at the left, middle, and right points of Maery Bridge near the Mulgeum and Maery algae monitoring network located downstream of the Nakdong River. The phycocyanin concentration(PC) was measured in the field using the LISST-HA

Heavy metals can be intentionally or unintentionally introduced into plastic food utensils, containers, and packaging (PFUCP) as additives or contaminants, which can be ingested with food by humans. Here, seven-heavy metals (lead, cadmium, nickel, chromium, antimony, copper, and manganese) with toxicity concerns were selected, and risk assessment was done by establishing their migration from 137 PFUCP products made of 16 materials distributed in Korea. Migration of heavy metals was examined by a
