background: given the increasing importance of suspended particles and reporting weather conditions in the amount of ultraviolet radiation in many countries, in this study, the data of the maximum amounts of pollution by suspended particles with the size of 10, 2.5 and1 microns (pm10, pm2.5, pm1) which were reported in 1-hour time-series and global ultraviolet index (uvi) were used to predict t...

The in vitro antibacterial activity of ginger (Zingiber officinale) essential oil (GEO) was tested against five Gram-negative and Gram-positive fish pathgenic bacteria isolated from farmed olive flounder (Paralichthys olivaceus) in Korea. According to the results of disk diffusion, minimum inhibitory and minimum bactericidal concentration (MIC and MBC) tests, GEO was active against most of the ...

Mangroves acted as sinks of terrestrial pollutants, but the occurrence and contamination rare earth elements (REEs) in urban mangroves lacked systematic evaluation. In rapidly developing Shenzhen, China, four typical were selected to determine REEs mangroves, including Baguang mangrove (BGM) Futian (FTM) featured with ecological preserve central business district, respectively; Xixiang (XXM) Sh...

Activity concentrations of radionuclides (238U, 226Ra, 232Th, and 40K) in the sediments eight sampling stations heavy metal (Cr, Co, Ni, Cu, Zn, As, Cd, Pb) two long cores from Nansha Sea area were obtained by high-purity germanium spectroscopy inductively coupled plasma atomic emission spectrometry. In a correlation analysis between metals, 232Th was positively correlated with As Pb. 238U demo...
