“…It is well known that the quantity and type of waste disposed of on the beaches are directly correlated to the number of persons in such locations [53]. Also, oceanographic characteristics such as tides, coastal currents, and upwelling systems added to the influence of socioeconomic activities may locally influence levels of hazardous substances disposed of as sewage [54]. In the present study, higher average ammonium concentrations were seen in BC (17.8 µg/L) and Neg (3.7 µg/L), suggesting coastal transport of residues from more populated zones to PNNT.…”

Since 2013, there has been an increase (>23%) in naval traffic using maritime routes and ports on the coastal fringe of Santa Marta, Colombia. Of major concern, and described by several studies, is the relationship between maritime traffic and coastal contamination. This study proposed a maritime traffic indicator considering the simultaneous effects of several relevant measurements of water quality parameters to estimate the impact of naval activity. The approach involved developing a model including the number of vessels, hull length, and permanence time in berths. In addition, water quality variables, considering climatic seasons, were used to verify association with maritime traffic and touristic activities. The high concentrations of total coliforms (TC) and dissolved/dispersed petroleum hydrocarbons in chrysene equivalents (DDPH) reported by the International Marina of Santa Marta (SM) were affected by the local anthropic activities, including tourism, naval traffic, and urban wastewater discharges. Moreover, our results suggest the occurrence of multiple chemical impacts within Tayrona National Natural Park (PNNT) affecting conservation goals. The estimation of the maritime traffic indicator proposed in this study may be an easy and more complete tool for future studies evaluating the impact of naval activities on environmental quality.

“…Os HSF possuem a propriedade de exercer efeitos no organismo, na reprodução, no crescimento dentre outras. Diante desta real ameaça que os hormônios podem conferir a organismos de diferentes ecossistemas, vários trabalhos recentes foram encontrados na literatura que reportam a presença destes CIEs em diferentes matrizes aquosas no Brasil (PINHEIRO et al, 2015;PUSCEDDU et al, 2019;TEIXEIRA et al, 2017).…”

“…The authors observed that the occurrence of estrogens in these sediments was diffuse and partially related to a domestic sewage outfall. Estrogens were also found in areas with a substantial contribution of sanitary effluent from domiciles not covered by sanitation services [14].…”

Electroanalytical Determination of Estrone in Seawater Samples Using Functionalized Multiwalled Carbon Nanotubes

et al. 2021

In this work, a glassy carbon electrode (GCE) modified with multiwalled carbon nanotubes functionalized with carboxylic groups (MWCNT−COOH) was used to determine the hormone estrone in seawater samples. Modification of the electrode was optimized using three successive 10‐μL aliquots of the MWCNT−COOH dispersion in ethanol (1 : 5 mL). The cyclic voltammetry results showed an oxidation peak at 0.59 V with characteristics of an irreversible process, pH dependent and controlled by adsorption of species. The results of square‐wave voltammetry showed that the intensities of peak currents for the MWCNT−COOH/GCE were about 2.5 times higher than for GCE. The calibration curve showed a linearity of 0.9981 and a sensitivity of 0.1521 μA/mol L−1. The limits of detection and quantification were 0.117 and 0.392 μmol L−1, respectively. The recovery obtained using seawater samples was 91%, indicating the applicability of the method in marine environments.
