Efectos en la salud de los microplásticos
AI summary Read the abstract
Researchers conducted a systematic review of microplastic health effects on humans, finding evidence that microplastics in water, air, and food can penetrate tissues and organs, causing cellular damage, inflammation, oxidative stress, and immune responses, and called for stricter regulatory controls and further research to quantify long-term health impacts.
El uso de plásticos se ha multiplicado durante los últimos años debido a su facilidad para poder comercializar muchos productos utilizándolos. Su principal inconveniente radica en las tasas de reciclaje y en que su degradación en el medio ambiente es muy lenta. Al descomponerse, se forman los microplásticos, cuyo principal problema se encuentra en la contaminación de la atmósfera y de los océanos, pasando a los animales que reciben su daño de manera directa y esto tiene una repercusión muy seria en la salud pública debido a su consumo. El objetivo principal de este TFG es estudiar los problemas que causan los microplásticos en la salud del ser humano debido a su consumo, exposición y su toxicidad. Como objetivos específicos del TFG, se revisará la literatura existente sobre microplásticos presentes en el agua, en el aire y en la dieta para, de esta manera, saber cómo afecta a la salud del ser humano. Para llevar a cabo este objetivo, se ha realizado una metodología de revisión sistemática. Se han encontrado estudios en los que se evidencia que los microplásticos producen alteraciones en los seres vivos. Son capaces de introducirse en tejidos y órganos, causando daño celular, inflamaciones, estrés oxidativo e incluso respuestas inmunes localizadas a estas sustancias e incluso el deterioro de funciones vitales debido a su presencia en alimentos y bebidas. Es necesario establecer un control más estricto para este tipo de contaminante, además de implementar medidas para reducir su presencia medioambiental y realizar más estudios para analizar sus daños en la salud.
