“…Jonathan et al. () studied the GI of heavy metals in beach sediments near Santa Rosalía copper mine, reporting that the metal concentrations ranged between strongly polluted to extremely polluted quantities. The enrichment of metals has been directly related to the historical mining and ore processing activities in this region.…”

Rapid industrialization has led to an extraordinary increase in environmental pollution in Arak, Iran. This study classified the distribution of iron (Fe), manganese (Mn), lead (Pb) and cadmium (Cd) in sediments and soils of Mighan Playa (Iran) and analysed the pollution sources using geostatistical methods. Samples were taken from 250 points and the data analysed by means of SPSS, GS+ and ArcGIS. The soils were moderate to considerable polluted with Pb and high to very high polluted with Cd.

“…El elemento mayormente enriquecido en Santa Rosalía, de acuerdo al presente estudio, fue el Cu, el cual rebasa un FEN de 50, con concentraciones elevadas en sitios de esta zona de estudio reportadas previamente por otros autores (Shumilin et al, 2000(Shumilin et al, , 2005(Shumilin et al, , 2011(Shumilin et al, , 2012(Shumilin et al, , 2013Rodríguez-Figueroa 2009;Jonathan et al 2016).

“…La zona de Santa Rosalía presenta áreas contaminadas por desechos mineros (Shumillin et al 2011(Shumillin et al , 2012(Shumillin et al , 2013Jonathan et al 2016), independientemente de que existan asentamientos humanos normales. En uno de los estudios, Shumillin et al (2012) determinaron que las concentraciones de Pb (46.7 mg kg -1 ± 218 mg kg -1 ), Cu (3,390 ± 804 mg kg -1 ) y Zn (1,916 ± 749 mg kg -1 ) en la mayoría de las muestras de sedimentos fueron superiores al efecto de rango medio (ERM), lo que indica un impacto antropogénico extenso por actividades mineras de cobre en sedimentos de playa, y por lo tanto un alto riesgo toxicológico para la biota marina residente del área.…”

Vargas RESUMENAntecedentes. Existe un reciente interés por el estudio de diatomeas bentónicas marinas (DBM) y su respuesta a contaminación por elementos potencialmente tóxicos (EPT), principalmente metales que pueden impactar la composición de especies, alterar los parámetros de las asociaciones, y ocasionar deformaciones de las frústulas de diatomeas. Objetivo. Explorar qué cambios en las asociaciones de DBM podrían representar una respuesta a contaminación por EPT en ambientes marinos, usando de referencia la estructura típica de sus asociaciones, incluyendo florística, riqueza, diversidad y dominancia, así como frecuencia de frústulas deformes. Métodos. Se tomaron muestras de roca y sedimento en mayo 2015 y enero 2016 en Santa Rosalía, BCS, una playa contaminada con desechos mineros. Resultados. Se apoyó parcialmente la hipótesis propuesta, i.e., se registró entre 1 y 7.6% de valvas deformes por sitio; esta frecuencia de frústulas deformes sugiere impacto de contaminación por EPT en el área. Se registraron valores de diversidad de H´ entre 1.1 a 4.3, los cuales están dentro de los intervalos típicos de diversidad para sitios no contaminados, a pesar de que concentraciones de EPT como Cu 3760 mg kg -1 , Zn 2294 mg kg -1 , Ni 401 mg kg -1 , Pb 216 mg kg -1 , registradas en el área sobrepasan los valores de efecto de rango medio, indicando que un 50% de la biota presente sería afectada. Conclusiones. Las elevadas abundancias de ciertos taxa sugieren su capacidad de tolerar PTE, mientras que aquellos que mostraron deformaciones de sus frústulas podrían considerarse taxa sensibles.

“…Table T1). The questions were also designed based on previous experiences of metal enrichment/pollution in water, sediments, and fish for nearly two decades by the "Earth System Science Research Group" on monitoring of tourist beach quality and microplastics (recently) (Retama et al 2016a, b;Vetrimurugan et al 2020) in different countries around the globe through the "Vision 2030" beach quality project (Colombia: Gutiérrez-Mosquera et al 2018;India: Krishnakumar et al 2014;Jonathan et al 2004;Jayaprakash et al 2015Jayaprakash et al , 2016Mondal et al 2020;Santhiya et al 2011Santhiya et al , 2016Malaysia: Nagarajan et al 2013;Mexico: Retama et al 2016a, b;Jonathan et al 2011Jonathan et al , 2015Jonathan et al , 2016Jonathan et al , 2019South Africa: Vetrimurugan et al 2016, 2019. All the prognostic research questions towards post pandemic effects were provided dichotomously with "yes" or "no" to accurately estimate the realistic future intuitions, while the interrogations on existing pandemic knowledge were based on several oncoming assessments on environmental reclamations.…”

The continuous endemic of the new SARS-CoV-2 virus brought a halt to the world's activities from February 2020. Our study intends to gauge public perceptions on the consequences of post-pandemic changes on the marine environment, particularly as they are related to tourist beach amenities. Totally, 16 nations' knowledge and views on various environmental viewpoints over the effects of epidemic were gathered through public polls live on social media during social confinement in 2020. The results indicate that around 85% of respondents were most concerned about the alarming sights of widespread plastic trash and the increase of dangerous biomedical wastes through wastewater in the marine ecosystem. The outcomes of this study will undoubtedly aid in the establishment of a management strategy and for future studies on the consequences of any epidemic on the beaches.
