The recent rapid growth of the battery industry has led to a rapid increase in methylene chloride emissions. Methylene chloride causes health and social problems in humans. In this study, cellulose-based activated carbon fibers (CACFs) with improved yield were prepared for the removal of methylene chloride. The concentration of ammonium phosphate in the pretreatment controlled the crosslink density of cellulose fibers and improved the yield. From the results, the specific surface area and total pore volume of cellulose-based activated carbon fibers pretreated with ammonium phosphate (AP-CACFs) were determined to be 1920-2060 m/g and 0.83-1.02 cm/g, respectively, and the total yield improved by 6.78-11.59% compared to that of CACFs (4.97%). In particular, a correlation between the textural properties of CACFs and methylene chloride adsorption/desorption behavior was obtained. This correlation can be used to develop efficient adsorbents for methylene chloride removal.

Synthetic dyes, such as methylene blue (MB), are increasingly becoming sources of water pollution and require better treatment strategies. This study describes an eco-friendly method for methylene blue degradation using green synthesized iron oxide nanoparticles form Ureibacillus chungkukjangi. This bacterium was isolated from clinical samples and identified using 16S rRNA gene amplification and sequenced using Sanger sequencing technology.

Little is known about maternal occupational exposure to hydrocarbons and offspring cancer risk. We aimed to estimate childhood cancer risk associated with maternal exposure to aliphatic/alicyclic, aromatic, and chlorinated hydrocarbons, and methylene chloride, trichloroethylene, 1,1,1-trichloroethane, and toluene. In this case-control study, all cancer cases (N = 10 442) diagnosed at less than 20 years (born 1968-2016) in Denmark were matched to 261 050 cancer-free controls (25 : 1 matching ratio).

Hance (Viburnaceae), the Korean elderberry, is widely used in herbal medicine and in the food industry. It is known to have various pharmacological effects, including antitumor, antioxidant, anti-inflammatory, and antimicrobial activities. During our search for anti- compounds from natural resources, the methanol extract of the branch significantly inhibited the growth of .
