The Journal Impact Quartile of Science of the Total Environment is Q1. The k values (or t1/2 values) for the loss of 60Co and 134Cs from water and their uptake and loss from biota can be used to establish parameter values for assessment models. A continuous gas geochemistry programme was started at Furnas volcano in October 2001 with the installation of a permanent soil CO2 efflux station that has coupled meteorological sensors to measure barometric pressure, rain, air and soil temperature, air humidity, soil water content and wind speed and direction. With the exception of one study of chemical plant workers that reported an excess of stomach cancer, all the suggested associations of increased cancer risks and dioxin exposures are from studies of herbicide applicators. A similar test was performed in another degassing area, Mosteiros village, located on the flank of Sete Cidades volcano (S. Miguel Island), showing the same kind of relation between indoor CO2 concentrations and barometric pressure. The toxicokinetics were studied in 9 male, healthy volunteers exposed to solvent vapours in an exposure chamber for 2 h during a work load of 50 W. The subjects were exposed to 11 mg/m3 of 1,2,4-TMB on two occasions; during exposure to 1,2,4-TMB vapour alone and during exposure to 300 mg/m3 of white spirit. Fatty degeneration was observed in the livers of all PCB-fed fish. For low level 129I/127I ratios, characteristic of environmental samples (10(-12) to 10(-7)), RNAA or SMA that includes important radiochemical preparation steps are used. The results show that more than 80% of the PCP-derived 13[C] remained in the upper layer of the soil column. The (129)I deposition fluence measured for Lake Baikal is attributed predominantly to releases from the former Soviet reprocessing facilities Chelyabinsk, Tomsk and Krasnoyarsk, while the (129)I deposition fluxes deduced for all other lakes are attributed to releases from the European reprocessing activities at Sellafield, Marcoule and La Hague.We analyzed the concentration of 129I in the water of 26 rivers covering most of the runoff from Sweden, with the aim of assessing current contamination levels, distribution patterns and potential sources in freshwater systems of northern Europe. Maximum 134Cs concentrations in forage fish were higher following hypolimnetic addition than epilimnetic addition. ... COVID-19: Impact by and on the Environment. ... Impact Factor.

F is the fraction of ingested activity that is excreted in milk plus urine, and u/m is the ratio between the transfer rates to urine and milk, respectively. Almost all samples were contaminated by 1,4-dioxane. We invite researchers and data scientists focused on Coronavirus vaccine, drug, clinical and other related research, to freely access these Elsevier solutions for your work. Indoor CO2 air concentration measurements at the floor level reached values as higher as 20.8 vol.% during stormy weather periods. year, scholars review current metrics to improve upon them and sometimes come up with new ones. Impact Factor … After the accident the mean 137Cs-concentration in reindeer meat from the 1986-87 slaughtering period was 720 Bq/kg fresh weight and in 1987-88, 630 Bq/kg fresh weight.Assessing the transfer of pentachlorophenol through soil columns using (13)[C]isotopeThe transfer of organic pollutants was studied through soil columns using 13[C]-labelled pentachlorophenol (PCP) as a model compound. First results confirm a higher winter contamination (11.67 vs. 2.79 micrograms/m3) and a higher contamination at the urban site, compared to rural and remote sites. Heavy metal deposition was collected monthly in Warren Spring Laboratory type inverted frisbees.
