IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

INTRODUCTION The Monjolinho River is an urban tropical stream located in São Carlos city, central region of São Paulo State.It has been receiving both treated and untreated effluents as a result of urbanization. Generally, the main organic sources of contaminants in aquatic ecosystems are the polycyclic aromatic hydrocarbons (PAHs), and aliphatic hydrocarbons (Mozeto et al., 2014). PAHs are known for their carcinogenicity and mutagenicity, consisting of two or more benzenoid groups (Marce et al., 2000). 16PAHs have been identified by USEPA as important emerging contaminants (Magi et al., 2002) and together with n-alkanes (the aliphatic hydrocarbons) their negative impacts on the water bodies of growing metropolitan areas become worse (Kotianova et al., 2007). Based on the general concern regarding water resource and aquatic life conservation, the studies focusing on our study area are insufficient. Therefore, our investigation was based on monitoring studies of the PAHs and n-alkanes in the sediment and water of Monjolinho River and to evaluate their possible sources that cause potential impacts on sediment–water quality. Several distribution or diagnostic indexes were also calculated to deduce the nature of potential sources of these hydrocarbons (biogenic, pyrogenic, and petrogenic).
