Processo de estabilização de resíduos orgânicos: vermicompostagem versus compostagem
Autor: Paulo R. Dores-Silva, Maria Diva Landgraf, Maria Olímpia de O. Rezende
Publikováno v: Química Nova, Vol 36, Iss 5, Pp 640-645 (2013)
Two processes are used to stabilize organic wastes: composting and vermicomposting.There are no studies in the literature showing which process is most effective over the short term. In this study, 3 organic wastes were composted and vermicomposted f

Autor: Maria Olímpia de Oliveira Rezende, Paulo R. Dores-Silva, Jussara Aparecida de Oliveira Cotta, Maria Diva Landgraf
Publikováno v: Journal of Environmental Science and Health, Part B. 54:598-604
Polycyclic Aromatic Hydrocarbons (PAHs) are among the environmental pollutants that have very high carcinogenic and mutagenic activity. Among hundreds of different PAHs, 17 are considered priority pollutants and routinely monitored for regulatory pur

Autor: Carmen Aparecida Cardoso Maia Camargo, Maria Diva Landgraf, Marcio Antonio Ferreira Camargo, Daniel Henrique Rattis Lemos
Publikováno v: OALib. :1-13
Mining causes numerous environmental impacts; among them we have to mention the water contamination due to the residues inherent to the activity. “Morro do Niquel”, a mining site, located in southwest Minas Gerais, Brazil, has promoted an increas

Autor: Gilberto Orivaldo Chierice, Antonia Marli dos Santos, Maria Diva Landgraf, Salvador Claro Neto, Marcio Antonio Ferreira Camargo
Publikováno v: OALib. :1-12
PCBs, polychlorinated biphenyls (polychlorinated biphenyls), are the generic names given to the class of organochlorine compounds resulting from the reaction of the biphenyl group with anhydrous chlorine in the presence of a catalyst. They are toxic,
