In order to determine the mineral composition of the soil from the urban area in the City of Niš, a team of researchers from the University of Niš, Faculty of Sciences and Mathematics, Department of Chemistry, have collected 15 soil samples near the city roads and analyzed them. Fourteen metals and four soil chemical characteristics were determined in the paper.
Ethane is the second most abundant component of natural gas, right after methane, and it is found deep underground and in marine gas deposits around the world. Research studies have shown that these two components—along with propane and butane—are being oxidized into carbon dioxide. Bacteria that convert methane, propane, and butane are already known, but it was unclear how ethane is degraded in the absence of oxygen, until now.
Pesticides are compounds that are used to kill pests, including insects, rodents, fungi and unwanted plants (e.g. weeds). When pesticides are used to protect crops, their residues will potentially affect and threaten human and environmental health. For that reason, they must be monitored and used safely, or even avoided, if possible.
