INVESTIGATION ON THE NATURE AND PROVENANCE OF PAH FOUND IN SEDIMENTS OF THE SOLIMÕES RIVER AND SOME ASSOCIATED LAKES
Autor: Tereza C. S. de Oliveira, Arthur de L Scofield, Luana M. Silva, Alcinei P. Lopes, Angela de L. R. Wagener
Publikováno v: Química Nova, Vol 46, Iss 6, Pp 573-581 (2023)
The present work aimed at evaluating indicators of hydrocarbon sources to sediments from the Solimões River region, in the central Amazon. The 16PAH, the alkylated homologs and molecular markers were investigated. The entire series of alkylated PAH

CARBON ISOTOPIC COMPOSITION OF LEAF WAX n-ALKANES OF MANGROVE PLANTS DISTRIBUTED ALONG A LATITUDINAL GRADIENT IN BRAZIL
Autor: Arthur de L. Scofield, Angela de Luca Rebello Wagener, Lilian Almeida, Mário Luiz Gomes Soares, Milena Ceccopieri, Renato S. Carreira, Cláudia Hamacher, Cassia O. Farias
Publikováno v: 30th International Meeting on Organic Geochemistry (IMOG 2021).
Summary Here we present baseline data of δ¹³C of n-alkanes (δ¹³Cn-alkanes) from leaf waxes of mangrove trees – Avicennia schaueriana, Rhizophora mangle and Laguncularia racemosa – distributed along a latitudinal gradient in Brazil. The obje
