Large quantities of microplastics are thought to be emitted freshwater environments via wastewater treatment plants (WWTPs). To evaluate the occurrence in Korean WWTPs, a nationwide study was conducted for first time 50 representative WWTPs with large capacities. Grab sampling and laboratory filtration were used influents, whereas situ using custom-made device effluents. The filtrates pretreated wet peroxidation density separation prior identification dissection microscope Fourier-transform...
A prediction model for estimating the ecotoxicity of water-accommodated fraction (WAF) and water-soluble (WSF) heavy crude oil is proposed. Iranian (IHC), one major components Hebei Spirit spill in Korea 2007, was used as a preparation WAF WSF. Luminescence inhibition Vibrio fischeri chosen test evaluating baseline toxicity aromatic hydrocarbons IHC. The measured concentration each chemical species WSF agreed well with predicted soluble calculated using Raoult's law from amount This...
Due to high usage of tetracycline antibiotics, concerns have been raised about their environmental fate. In this study, potential changes in the pseudo-first-order hydrolysis rate constants for three tetracyclines, (TC), oxytetracycline (OTC) and chlortetracycline (CTC), were evaluated by measuring batch column leaching experiments. The first-order measured at pH 5, 7, 9 using tests. values highest 7 all tetracyclines (0.0030 ± 0.0004, 0.0042 0.0001, 0.0323 0.0003 h−1 TC, OTC, CTC,...
Exposure assessment for three major active ingredients used humidifier disinfectants, polyhexamethylene guanidine (PHMG), oligo(2-(2-ethoxy)ethoxyethyl guanidinium chloride (PGH), and 5-chloro-2-methylisothiazol-3(2H)-one/2-methylisothiazol-3(2H)-one (CMIT/MIT) mixture, was conducted in a bedroom using an air sampler refined risk assessment. The experimental site selected to reflect consumer exposure conditions. Aerosols formed by were sampled during 8 hr at 7.5 L/min. Absorbed PHMG PGH the...
Worldwide, regulations of chemicals require short-term toxicity data for evaluating hazards and risks the chemicals. Current requirements on registration are primarily based tonnage do not yet consider properties For example, ecotoxicity required with production volume greater than 1 or 10 ton/y according to REACH, without considering chemical properties. Highly hydrophobic characterized by low water solubility slow bioconcentration kinetics, which may hamper interpretation experiments. In...
