<div style="text-align: justify;">
<span style="font-family: Times, Times New Roman, serif;"><span style="background-color: #e06666;">La marea roja de Florida</span> es causada por un alga microscópica llamada Karenia brevis, o K. brevis, (que se muestra aquí) que produce una toxina que puede afectar el sistema nervioso central de los peces, aves, mamíferos y otros animales, y también causa irritación respiratoria. en humanos.</span></div>
<div style="text-align: justify;">
<span style="font-family: Times, Times New Roman, serif;">• En concentraciones altas (llamadas floraciones), el organismo puede decolorar el agua -a veces roja, verde claro o oscura o marrón.</span></div>
<div style="text-align: justify;">
<span style="font-family: Times, Times New Roman, serif;">• Los efectos en la salud humana incluyen casos de intoxicación humana por intoxicación neurotóxica por mariscos (NSP) e impactos en la función respiratoria humana.</span></div>
<div style="text-align: justify;">
<span style="font-family: Times, Times New Roman, serif;">• Los impactos ambientales incluyen muertes masivas de peces, mamíferos marinos, tortugas marinas y mortalidad de aves marinas, e impactos en las comunidades bentónicas, incluidos los pastos marinos y la extinción de comunidades de coral.</span></div>
<div style="text-align: justify;">
<span style="font-family: Times, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Times, Times New Roman, serif;"><span style="background-color: #e06666;">Florida Red Tide</span> is caused by a microscopic alga called Karenia brevis, or K. brevis, (pictured here) which produces a toxin that can affect the central nervous system of fish, birds, mammals, and other animals, as well as cause respiratory irritation in humans.</span></div>
<div style="text-align: justify;">
<span style="font-family: Times, Times New Roman, serif;">•At high concentrations (called blooms), the organism may discolor the water –sometimes red, light or dark green, or brown.</span></div>
<div style="text-align: justify;">
<span style="font-family: Times, Times New Roman, serif;">•Human health effects include cases of human intoxication from neurotoxic shellfish poisoning (NSP) and impacts on human respiratory function.</span></div>
<div style="text-align: justify;">
<span style="font-family: Times, Times New Roman, serif;">•Environmental impacts include massive fish kills, marine mammal, sea turtle and sea bird mortalities, and impacts on benthic communities including sea grass and coral community die-offs.</span></div>
<div style="text-align: justify;">
<span style="font-family: Times, Times New Roman, serif;">•Harmful Algal Blooms (or HABs) such as #redtide occur worldwide. However, K. brevis is found almost exclusively in the Gulf of Mexico but has been found on the east coast of Florida and off the coast of North Carolina.</span></div>
<div style="text-align: justify;">
<span style="font-family: Times, Times New Roman, serif;">•Red tide was first officially recorded in Florida in 1844, but reports along the Florida Gulf Coast by Spanish explorers date back as far as the 1500s.</span></div>
<div style="text-align: justify;">
<span style="font-family: Times, Times New Roman, serif;">• Red Tide Blooms can last days, weeks, or months and can also change daily due to wind conditions. Onshore winds normally bring it near the shore whereas offshore winds drive it out to sea.</span></div>
<div style="text-align: justify;">
<span style="font-family: Times, Times New Roman, serif;">•No single factor causes a red tide bloom. It needs Biology (the organisms), Chemistry (appropriate conditions and nutrients for growth), Physics (concentrating and transport mechanisms). Tests are being conducted to see if coastal nutrients enhance or prolong blooms, however there are no conclusive results as of yet.</span></div>

<span style="font-size: large;">En los gifs se puede ver el momento en que se agregó el peróxido de hidrógeno a la / mezcla de cobre y sulfato de luminol / sodio / hidróxido de potasio-tiocianato. El peróxido oxida el cobre luminol espontáneamente lo que emite una luz azul brillante. Después de eso, la concentración del cobre cae de nuevo a casi de 0, por lo tanto no se emite luz. Por el momento, la concentración de cobre aumenta de nuevo lo que significa la emisión de luz y comienza de nuevo, esto se llama oscilación</span></div>

~ <span style="background-color: white; font-family: Courier New, Courier, monospace; line-height: 19.5px;"><span style="font-size: large;">El ácido nítrico (HNO</span><span style="font-size: x-small;">3</span><span style="font-size: large;">) es un es un líquido viscoso, corrosivo y tóxico que puede ocasionar graves quemaduras en los seres vivos. Se utiliza para fabricar explosivos cómo la nitroglicerina y trinitrotolueno (TNT), así como fertilizantes como el nitrato de amonio. Tiene usos adicionales en metalurgia y en refinado, ya que reacciona con la mayoría de los metales y en la síntesis química. Cuando se mezcla con el ácido clorhídrico forma el agua regia, un raro reactivo capaz de disolver el oro y el platino. El ácido nítrico también es un componente de la lluvia ácida.</span></span></div>

<span style="background-color: white; font-family: Courier New, Courier, monospace; font-size: large; line-height: 19.5px;">El ácido nítrico puro es un líquido viscoso, incoloro e inodoro. A menudo, distintas impurezas lo colorean de amarillo-marrón. A temperatura ambiente libera humos rojos o amarillos. El ácido nítrico concentrado tiñe la piel humana de amarillo al contacto, debido a una reacción con la cisteína presente en la queratina de la piel. El ácido nítrico es un agente oxidante potente. sus reacciones con compuestos como los cianuros, carburos, y polvos metálicos pueden ser explosivas. </span></div>
