Esponjas de cozinha liberam microplásticos na lavagem diária de louça

Um estudo da Universidade de Bonn mostra que esponjas de cozinha liberam microplásticos durante o uso regular. As emissões variam de acordo com o tipo de esponja, mas o consumo de água é o principal fator do impacto ambiental na lavagem de louça à mão.

Os pesquisadores testaram três tipos de esponjas em residências na Alemanha e na América do Norte, bem como em um dispositivo de laboratório chamado SpongeBot. Todas as esponjas perderam material, liberando entre 0,68 gramas e 4,21 gramas de microplásticos por pessoa a cada ano. Esponjas com menor teor de plástico liberaram menos partículas.

Researchers at the University of Vienna have determined that land releases more than 20 times as many microplastic particles into the atmosphere as the oceans, challenging prior assumptions. Their study, published in Nature, used global measurements to correct overestimated emission models. The findings highlight land as the dominant source, though uncertainties persist.

Researchers have found unexpectedly high levels of methylsiloxanes, a class of silicone compounds, present in air samples from cities, rural areas, and forests around the world. The study links much of the pollution to vehicle emissions from engine oil additives. Experts warn that daily human inhalation of these substances may exceed exposure to other known pollutants like PFAS.
