Abstract:Little attention has been paid to the effects of soil mineralogy on remediation efficiency of sewage sludge. To fill this gap, we applied limed sewage sludge to Pb‐contaminated soil samples of an Oxisol rich in hematite (309 g kg−1) and gibbsite (322 g kg−1) and to an Inceptisol rich in kaolinite (683 g kg−1). Soil samples were collected from B horizon, being both of them acid, clayey, and poor in organic matter. Soil samples were incubated for 40 days and evaluated for Pb after fractioning. Limed sewage sludg… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
