“…The analytical procedure (e.g. extraction, cleanup and quantification) for the determination of markers was based on the method described by Morais et al (2019). Initially, 30 g of sediment (freeze-dried) were extracted by ultrasonication using acetone, ethyl acetate, dichloromethane and hexane as solvents.…”

“…A growing approach applied to tracers of human activities in industrial, rural and urban areas is based on information of specific organic substances known as molecular markers or biomarkers (Lima et al , 2019; Morais et al , 2019; Santos et al , 2019). Molecular markers are compounds of natural and anthropogenic origin that provide information based on isotopic composition, chemical structure and the molecular distribution of individual or mixtures of substances.…”

“…Markers such as sterols (natural and fecal) and hormones (natural and synthetic) have been successfully applied to the study of sewage contamination in coastal sediments. The molecular marker approach is an alternative to the analysis of microorganisms, such as fecal coliforms and Escherichia coli , which are common tools for the evaluation of sewage input (Froehner et al , 2012; Abreu-Mota et al , 2014; Martins et al , 2014; Carreira et al , 2015; Venturini et al , 2015; Lima et al , 2019; Morais et al , 2019; Santos et al , 2019).…”

“…Both markers are preponderant in places subjected to human sewage release (treated and raw), water treatment plant effluent, solid residue release and runoff from animal husbandry activities (livestock, poultry, fish and shrimp farming), the management of which involves the use of drugs (antibiotics, hormones, etc.) (Froehner et al , 2012; Lapworth et al , 2012; Wang et al , 2015; Lima et al , 2019; Morais et al , 2019). Therefore, these compounds have been widely used as markers in environmental diagnostic studies (Froehner et al , 2012; Abreu-Mota et al , 2014; Carreira et al , 2015; Pimentel et al , 2016).…”

Purpose An efficient and adequate environmental monitoring plan is essential to any integrated coastal zone management (ICZM) program. The purpose of this paper is to apply an environmental diagnostic study to a coastal lagoon using anthropogenic markers as a decision support tool to aid the development of coastal environmental management policies. Design/methodology/approach Specifically, environmental status and anthropogenic sources were determined as part of a coastal environmental management plan; a study of human occupation and use was conducted to determine the predominant human activities around the lagoon; an environmental diagnostic study was conducted to determine the occurrence, levels and distribution of markers; and the results of the environmental diagnostic study were compared to indicators stipulated in Brazilian legislation. Findings Land use study revealed both urban and rural activities around the lagoon, as evidenced by the existence of residences, restaurants as well as poultry and livestock activities. The environmental diagnostic study revealed the input of human sewage (treated and raw) and runoff from animal husbandry activities. Practical implications The information produced using anthropogenic markers showed the influence of less studied rural activities, such as livestock and poultry farming, thereby providing a more reliable environmental status compared to the use of classic indicators employed in laws issued by international and Brazilian agencies. Originality/value The present results show that classic indicators used by environmental agencies are insufficient for an accurate diagnosis of coastal zones with multiple anthropogenic activities. Thus, the modernization of the environmental monitoring plan of the ICZM program is urgently needed for a more accurate assessment of coastal environments.
