“…Excretion from humans and other animals is considered the major source of natural estrogens (Froehner et al , 2012; Adeel et al , 2017). Natural and synthetic hormones were identified and quantified at all sampling sites and, although there is no diagnostic ratio for hormones yet, their occurrence or absence could be used to diagnose the status of natural and manmade environments (Lapworth et al , 2012; Adeel et al , 2017; Lima et al , 2019; Santos et al , 2019).…”

“…The synthetic hormones EE2 and DES are widely used in oral contraceptives and are the result of excretion by organisms (De PaivaPessoa et al , 2012). Despite the scarcity of data, there is increasing evidence that synthetic estrogens are also associated with runoff from animal husbandry activities, the management of which involves the use of drugs, especially those linked to an increase body weight during the fattening phase and sexual reversal (Lapworth et al , 2012; Costa Junior et al , 2014; Wang et al , 2015; Liu et al , 2017; Santos et al , 2019). Thus, this class is indicative both urban and rural activities and each classification originated a different product with its respective interpolated values (Figures 3 and 7).…”

“…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).…”

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.

“…Flu, Phe, and Ant mainly derived from activities on petroleum raw materials, such as the volatilization and leakage of petroleum products [54]. This could be due to anthropogenic activities such as ship repairing and oil spills from ships in transport [55]. Thus, PC2 was assigned as a source from petroleum.…”

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants in sediments and pose a serious risk for freshwater ecosystems. In this study, sediment samples from 24 sites were collected from the cyanobacterial bloom-occurring, macrophyte-growing lake bay and adjoining river of Taihu Lake. Here, the concentration levels, sources, and risk assessment of 16 priority PAHs in the surface sediments from typical algae, macrophyte lake bay and adjoining river of Taihu Lake, were investigated, and the results were compared with those of previous studies. The total PAH (ΣPAH) concentrations ranged from 4900 to 16,800 ng·g−1 in sediments of the Taihu Lake bay and from 5736.2 to 69,362.8 ng·g−1 in sediments of the adjoining river. The level of PAHs in riverine sediments was significantly higher than those of the Taihu Lake bay, and that of the Dongshan River was significantly higher than that of the Mashan River, while there was no significant difference in the concentrations of PAHs between the cyanobacterial bloom-occurring and macrophyte-growing lake zone. The results indicated petroleum contamination was dominated in the cyanobacterial bloom-occurring, macrophyte-growing lake bay, while PAHs of the riverine sediments derived from petroleum contamination and the combined combustion including wood, coal combustion, and petroleum combustion according to the identification by the molecular diagnostic ratio and principal component analysis (PCA). Sediment risk assessment based on sediment quality guidelines (SQGs) suggested that partial regions of the Taihu Lake bay were subjected to the potential ecological risk of the 3-ring and 5-ring PAHs, and there existed negative effects related to naphthalene pollutant in all survey regions. The adjoining riverine sediments showed a high ecological risk.
