Short-Term Effects of Wildfire Ash on Water Quality Parameters: A Laboratory Approach.

Bull Environ Contam Toxicol 2021 Apr 8. Epub 2021 Apr 8.

Centro Universitário de Brasília (UniCEUB), SEPN 707/907, Asa Norte, Brasília, Federal District (DF), 70790-075, Brazil.

Climate change coupled with inappropriate burning practices has increased large-scale wildfires in Brazilian tropical savannahs (Cerrado). Considering that the effects of ash from wildfires on water parameters are scarcely known in tropical savannahs, this study investigated the chemical changes caused by ash in the soft water, commonly used for bioassays. To this end, ash samples were collected immediately following a fire in a Cerrado area (Federal District, Brazil) and put into water (1:10 ash:soft-water m/v) to check physical parameters under laboratory conditions.

COVID-19 Pandemic on Fire: Evolved Propensities for Nocturnal Activities as a Liability Against Epidemiological Control.

Front Psychol 2021 22;12:646711. Epub 2021 Mar 22.

Department of Experimental Psychology, Institute of Psychology, University of São Paulo, São Paulo, Brazil.

Humans have been using fire for hundreds of millennia, creating an ancestral expansion toward the nocturnal niche. The new adaptive challenges faced at night were recurrent enough to amplify existing psychological variation in our species. Night-time is dangerous and mysterious, so it selects for individuals with higher tendencies for paranoia, risk-taking, and sociability (because of security in numbers). Read More

Are Ionic Liquids Suitable for Suppressing Coal Spontaneous Combustion?

ACS Omega 2021 Mar 4;6(10):6681-6690. Epub 2021 Mar 4.

Laboratory of Gas and Fire Control for Coal Mines (China University of Mining and Technology), Ministry of Education, Xuzhou 221116, China.

Due to the reported fact that the active functional groups in coal can be dissolved and destroyed by ionic liquids, it is expected that the spontaneous combustion of coal can be affected from a thermodynamic perspective. However, ionic liquids with different thermal stabilities have distinct influences on coal combustion. Here, the thermal stability of long-flame coal in the presence of five pure ionic liquids ([Bmim][BF], [Bmim][Ac], [Bmim][NO], [Hoemim][BF], and [Pmim][BF]) was analyzed by thermogravimetric analysis, and the flammability of the raw coal, pure ionic liquids, and coal-IL mixtures (mass ratio of 1:1) were tested using a cone calorimeter according to the indexes of the time to ignition (TTI), mass loss rate (MLR), heat release rate (HRR), total heat release rate (THR), specific extinction area (SEA), and CO production.

Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), Paseo Sierra de Atapuerca 3, 09002, Burgos, Spain. Electronic address:

During the mid-Middle Pleistocene MIS 14 to MIS 11, humans spread through Western Europe from the Mediterranean peninsulas to the sub-Arctic region, and they did so not only during the warm periods but also during the glacial stages. In doing so, they were exposed to harsh environmental conditions, including low or extremely low temperatures. Here we review the distribution of archeological assemblages in Western Europe from MIS 14 to MIS 11 and obtain estimates of the climatic conditions at those localities. Read More

Role Of Intravenous Iron Over Nonsurgical Transfusions In Major Burns.

Ann Burns Fire Disasters 2020 Dec;33(4):299-303

Hospital Universitario Virgen del Rocío, Seville, Spain.

Anemia is a frequent condition in burn patients due to a mixture of blood loss and chronic inflammation. Transfusions increase the probability of serious infections and reduce overall survival, especially when unrelated to perioperative blood loss. Once the surgical phase in burn patients is completed, the role of parenteral iron administration in the reduction of subsequent transfusions is not well established. Read More

Graphene nanoplatelets and reduced graphene oxide elevate the microalgal cytotoxicity of nano-zirconium oxide.

Chemosphere 2021 Feb 20;276:130015. Epub 2021 Feb 20.

Institute of Environmental Sciences (CML), Leiden University, PO Box 9518, 2300 RA, Leiden, the Netherlands; National Institute of Public Health and the Environment (RIVM), Center for the Safety of Substances and Products, PO Box 1, 3720 BA, Bilthoven, the Netherlands.

Novel products often have a multitude of nanomaterials embedded; likewise within many products graphite-based products are decorated with nano-zirconium oxide (nZrO) because graphene is an ultrahigh conductive material whereas nZrO is for instance fire-retardant. As a consequence, the pristine/isolated nanoparticle has unique beneficial properties but it is no longer the only compound that needs to be considered in risk assessment. Data on joint toxicological implications are particularly important for the hazard assessment of multicomponent nanomaterials. Read More
