Journal ArticleDOI
Mechanisms of metal sorption by biochars: Biochar characteristics and modifications
Hong-Bo Li,Xiaoling Dong,Evandro B. da Silva,Letuzia M. de Oliveira,Yanshan Chen,Lena Q. Ma,Lena Q. Ma +6 more
TL;DR: This review summarizes the characteristics of biochar (e.g., surface area, porosity, pH, surface charge, functional groups, and mineral components) and main mechanisms governing sorption of As, Cr, Cd, Pb, and Hg by biochar and includes competitive sorption mechanisms of co-existing metals.
Journal ArticleDOI
Effects of arsenate, chromate, and sulfate on arsenic and chromium uptake and translocation by arsenic hyperaccumulator Pteris vittata L.
Letuzia M. de Oliveira,Lena Q. Ma,Lena Q. Ma,Jorge A.G. Santos,Luiz Roberto Guimarães Guilherme,Jason T. Lessl +5 more
TL;DR: It is demonstrated that As and Cr inhibited each other in uptake and translocation by PV but sulfate enhanced As andCr uptake and translation by PV, and addition of sulfate increased uptake and translator of As by 26-28% and Cr by 1.63 fold.
Journal ArticleDOI
PAHs in urban soils of two Florida cities: Background concentrations, distribution, and sources.
Yungen Liu,Peng Gao,Jing Su,Evandro B. da Silva,Letuzia M. de Oliveira,Timothy G. Townsend,Ping Xiang,Lena Q. Ma,Lena Q. Ma +8 more
TL;DR: The results showed that soils were dominated by high molecular weight PAHs in both cities, mainly from pyrogenic sources including vehicle emissions, and biomass and coal combustion and based on ArcGIS mapping, PAH concentrations in soils near business districts and high traffic roads were higher.
Journal ArticleDOI
Metal concentrations in traditional and herbal teas and their potential risks to human health.
Letuzia M. de Oliveira,Suchismita Das,Evandro B. da Silva,Peng Gao,Julia Gress,Yungen Liu,Lena Q. Ma,Lena Q. Ma +7 more
TL;DR: The data showed that it is important to consider metal intake from tea consumptions, especially for Cr and Al in heavy tea drinkers.
Journal ArticleDOI
Antioxidant enzymes responses in shoots of arsenic hyperaccumulator, Isatis cappadocica Desv., under interaction of arsenate and phosphate
TL;DR: High arsenate treatment could cause an increasing oxidative stress, which can be scavenged by the antioxidant enzyme, and high phosphate treatments had a positive effect on GR activity, which may be due to regulation of glutathione biosynthesis within the plants.
