“…The link between O&G and WQI is mostly due to the environmental and health hazards connected with these pollutants. According to Samsudin and Azid (2018), the use of WQI is a straightforward procedure that offers an appropriate assessment of water quality.…”

Oil and grease (O&G) concentrations were determined on the West Coast of Sabah to identify pollution hotspots and to understand the extent of the issue. Triplicate seawater samples were collected at twenty-five stations during the northeast (November 2020 to February 2021) and southwest (July 2021 to September 2021) monsoons. QGIS software was used to create a map model, and water quality indexes were used to provide information on the status of the marine ecosystem and marine biota preservation. O&G concentrations were significantly higher (p<0.05) in certain areas of the West Coast of Sabah, ranging from 0.05±0.03 mg/L to 39.34±1.01 mg/L. According to the Malaysian Marine Water Quality Standards, O&G concentrations in the study area were categorized into Class 3, which is directly exposed to the discharge of effluent from anthropogenic activities. Hence, ecosystems in these areas were susceptible to some degree of deterioration. This suggests a potential source of pollution that requires further investigation and remediation efforts. However, the Water Quality Index revealed that the study areas were classified into moderate, acceptable, and medium status, which were still within the acceptable limit for the conservation of marine biota. The findings underscore the need for continued research and proactive measures to minimize O&G pollution and protect ecosystems in the study area. With increased awareness of oil spills, this favorable trend is projected to endure through effective management methods and effective actions to prevent O&G pollution along the West Coast of Sabah. Oil and grease pollution have the potential to endure in the environment for extended periods, ranging from years to even decades, resulting in enduring ecological harm, and hindering the restoration of ecological systems.

“…All the reagents were added to the prepared 7 kg soil in pots (25 cm × 14 cm × 18 cm) according to the concentration of each treatment. In order to ensure sufficient nutrients for plant growth, 0.2 g of urea and 0.1 g of potassium dihydrogen phosphate were applied to every kg of soil (Samsudin et al, 2018). The soil was permitted to equilibrate for 30 d after lead and cadmium contamination.…”

To evaluate physiological changes of Japanese honeysuckle under lead and cadmium stress, pot-plant experiment was adopted to discover heavy metal Pb or Cd single stress and Pb+Cd combined stress on part of physiological parameters of. Japanese honeysuckle. The results showed that under the same treatment, as time prolonged, the content of soluble sugar and soluble protein was decreased, the activity of SOD declined, the amount of free proline and MDA increased and the activity of CAT elevated. Under Pb stress only, total Chlorophyll content rose first and dropped afterwards and POD activity increased, however, under Cd stress only and Pb+Cd stress, both THCL content and POD activity first rose and then declined. In addition, under Pb or Cd single stress and combined stress, as treatment concentration increased, the contents of soluble sugar, soluble protein, free proline and MDA increased accompanied by POD, CAT and SOD activity increased while TCHL content decreased. All these indicate that under certain range of heavy metal stress, Japanese honeysuckle can reduce metabolic disorder plant damage caused by heavy metal stress through increasing osmotic regulating substances of leaves and inducing scavenging system of active oxygen.

“…Para ello, se toma en cuenta el uso dado, la ocurrencia de procesos naturales, y las actividades antropogénicas cercanas (Vivas-Aguas & Navarrete-Ramírez, 2014). La mayoría de estos estudios se basa en la determinación de variables fisicoquímicas como oxígeno disuelto (OD), temperatura, turbidez, salinidad; determinación de las concentraciones de nitrato y fosfato, cantidad de sólidos suspendidos totales (SST), demanda bioquímica de oxígeno (DBO), presencia de hidrocarburos derivados del petróleo o de elementos tóxicos, al igual que de variables microbiológicas, como coliformes fecales (CF), Escherichia coli (E. coli) y Enteroccocus faecalis (E. faecalis) (Nguyen & Sevando, 2019;Samsudin & Azid, 2018;Tanjung et al, 2019;Vivas-Aguas & Navarrete-Ramírez, 2014).…”

Introducción: El crecimiento socioeconómico ha causado presión sobre los ecosistemas marinos, y existe poca información que pueda ser utilizada para el manejo de playas en Nicoya, Costa Rica. Objetivo: Determinar la calidad fisicoquímica y microbiológica del agua marino-costera en Nicoya, Costa Rica. Métodos: En octubre de 2021, y mayo y junio de 2022, usamos métodos estándar para evaluar las condiciones fisicoquímicas y microbiológicas del agua, en tres playas con diferentes administraciones y número de turistas. Resultados: La temperatura del agua osciló entre 26,1°C y 31,2°C, la salinidad entre 22 y 31ups, el oxígeno disuelto entre 3,6 y 7,3mg/L y los valores de hidrocarburos totales suspendidos estuvieron por debajo del límite de detección. La mayor contaminación fecal se encontró en época de lluvias, con valores máximos de 3,5x103 NMP/100mL coliformes fecales, 1,1x103 NMP/100mL Escherichia coli y 2,4x103 NMP/100mL Enteroccocus faecalis. Conclusión: Si bien la contaminación fecal fue alta durante la época de lluvias, los parámetros fisicoquímicos fueron aceptables en las tres playas.
