ABSTRACT
Perfluorooctanoic acid (PFOA) and Perfluorooctane sulfonate (PFOS) are resistant to breakdown and are now considered global contaminants. However, interest in these recalcitrant compounds among scientists and legislators has grown significantly in recent years. In the present study, we analyzed the level of PFOA and PFOS contamination in surface water from the coastal regions of Tamil Nadu and West Bengal. After solid phase extraction, 49 samples were analyzed by liquid chromatography coupled with mass spectrometry (LOD ≤ 1.5 ng L-1). The PFOA and PFOS present in all samples at the highest concentration were found in the Ennore coastal region (reaching a maximum of 24.8 ng L-1 and 13.9 ng L-1 in CH-6 and CH-14 respectively). Similarly, on the West Bengal coast, concentrations of PFOA ranged from <1.5 to 14.0 ng L-1 and <1.3 to 8.2 ng g-1 in water and sediment respectively. PFOS concentrations in water and sediment ranged from <1.2 to 9.0 ng L-1 and <1.2 to 7.9 ng g-1, respectively. According to the principal component analysis, the majority of the variances (65.04 %) show a positive association, which points to industrial and domestic discharges as significant point sources of these compounds. The results from this study could be used to determine and understand the levels of PFOA and PFOS contamination along the Indian Coast as well as provide baseline information for imminent monitoring investigations. The environmental occurrences of PFOA and PFOS reported in the current study would allow policymakers to take appropriate measures to safeguard coastal ecosystems or reduce the likelihood of contamination, creating a sustainable and healthy environment.
ABSTRACT
El consumo problemático de sustancias entre los adolescentes, presenta tasas de prevalencia considerable a nivel mundial y se constituye en un problema de salud pública, indispensable de ser abordado, considerando la etapa del ciclo vital de esta población. El presente artículo tiene por objetivo, realizar un revisión del estado actual de los tratamientos indicados para los trastornos por abuso o dependencia de sustancias en adolescentes y de los resultados y evidencia que respaldan su efectividad, con el objetivo de orientar tanto a profesionales de la salud, como a los principales actores sociales que se relacionan con estos jóvenes (familiares, escuelas, centros comunitarios), en la posibilidad de optar por intervenciones que se ajusten a las necesidades específicas del joven, según su etapa evolutiva, nivel de desarrollo y su contexto natural más cercano.
Problematic substance use among adolescents presents significant rates worldwide prevalence and constitutes a public health problem, which is essential to be addressed, considering the stage of the life cycle of this population. This article aims, conduct a review of the current state of the indicated treatments for substance use disorders in adolescents, and the results and evidence supporting its effectiveness, with the aim of assisting both professionals health, as major social actors that relate to these young people (family, schools, community centers), the possibility of opting for interventions that meet the specific needs of the young, by evolutionary stage, level of development, and its closest natural context.
