Els filtres qu\u00edmics o org\u00e0nics<\/strong> absorbeixen les radiacions solars i, gr\u00e0cies a reaccions fotoqu\u00edmiques, les modifiquen per a minimitzar l’efecte perjudicial sobre la nostra pell.<\/p>\n\n\n\n Els filtres f\u00edsics o minerals<\/strong>, en canvi, tenen subst\u00e0ncies que reflecteixen la llum solar i actuen com a pantalla protectora. S\u00f3n els idonis per a persones amb pell sensible i nadons.<\/p>\n\n\n\n Una de les propietats m\u00e9s ben valorades \u00e9s que siguin resistents a l’aigua. Malgrat aix\u00f2, una part s’allibera al mar quan ens banyem. La quantitat de crema solar que queda a l’aigua augmenta en les zones amb m\u00e9s aflu\u00e8ncia de turistes, on milers de persones es banyen i en deixen les restes.<\/p>\n\n\n\n D’aquest fet sorgeix un problema, ja que alguns dels components qu\u00edmics que porten les cremes solars tenen efectes nocius pels ecosistemes marins, especialment pels coralls i tots els organismes aqu\u00e0tics que en depenen.<\/p>\n\n\n\n Alguns components qu\u00edmics inclosos en les cremes solars que s’ha demostrat que s\u00f3n perjudicials per al medi ambient s\u00f3n l’oxibenzona, l’octinoxat, l’octocril\u00e8, l’\u00e0cid aminobenzoic, l’enzacam\u00e8, l’octisalat, l’homosalat i l’avobenzona.<\/p>\n\n\n\n Alguns llocs tur\u00edstics, com Hawaii i la Riviera Maya, estan en proc\u00e9s de prohibir la venda de qualsevol crema solar que contingui oxibenzona o octinoxat en la seva composici\u00f3 per lluitar contra aquesta contaminaci\u00f3 qu\u00edmica.<\/p>\n\n\n\n Una alternativa per afavorir la conservaci\u00f3 del medi mar\u00ed sense deixar de protegir-nos contra el sol s\u00f3n les cremes solars biodegradables<\/strong>. Contenen filtres f\u00edsics, en la majoria de casos \u00f2xid de titani o \u00f2xid de zinc, no tenen en la seva composici\u00f3 cap dels productes qu\u00edmics citats anteriorment i nom\u00e9s inclouen productes biodegradables.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" L\u2019estiu ja ha arribat i protegir-nos de la radiaci\u00f3 solar \u00e9s molt important per la salut de la nostra pell. <\/p>\n","protected":false},"author":1,"featured_media":62,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":"","footnotes":""},"categories":[20],"tags":[72,24,25,124,134,91],"class_list":["post-5503","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-actualitat-medi-ambient","tag-aigua","tag-contaminacio","tag-ecoconsells","tag-ods12","tag-ods14","tag-turisme-sostenible"],"author_meta":{"display_name":"OSSMA","author_link":"https:\/\/www.ub.edu\/ossma\/en\/author\/ossmau1"},"featured_img":"https:\/\/www.ub.edu\/ossma\/wp-content\/uploads\/2016\/02\/ecoconsells.jpg","coauthors":[],"tax_additional":{"categories":{"linked":["Medi Ambient<\/a>"],"unlinked":["Medi Ambient<\/span>"]},"tags":{"linked":["aigua<\/a>","contaminacio<\/a>","ecoconsells<\/a>","ods12<\/a>","ods14<\/a>","turisme sostenible<\/a>"],"unlinked":["aigua<\/span>","contaminacio<\/span>","ecoconsells<\/span>","ods12<\/span>","ods14<\/span>","turisme sostenible<\/span>"]}},"comment_count":"2","relative_dates":{"created":"Posted 8 years ago","modified":"Updated 3 years ago"},"absolute_dates":{"created":"Posted on 27\/06\/2018","modified":"Updated on 14\/03\/2023"},"absolute_dates_time":{"created":"Posted on 27\/06\/2018 8:50","modified":"Updated on 14\/03\/2023 6:59"},"featured_img_caption":"","series_order":"","_links":{"self":[{"href":"https:\/\/www.ub.edu\/ossma\/en\/wp-json\/wp\/v2\/posts\/5503","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ub.edu\/ossma\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.ub.edu\/ossma\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.ub.edu\/ossma\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ub.edu\/ossma\/en\/wp-json\/wp\/v2\/comments?post=5503"}],"version-history":[{"count":8,"href":"https:\/\/www.ub.edu\/ossma\/en\/wp-json\/wp\/v2\/posts\/5503\/revisions"}],"predecessor-version":[{"id":46200,"href":"https:\/\/www.ub.edu\/ossma\/en\/wp-json\/wp\/v2\/posts\/5503\/revisions\/46200"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.ub.edu\/ossma\/en\/wp-json\/wp\/v2\/media\/62"}],"wp:attachment":[{"href":"https:\/\/www.ub.edu\/ossma\/en\/wp-json\/wp\/v2\/media?parent=5503"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.ub.edu\/ossma\/en\/wp-json\/wp\/v2\/categories?post=5503"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.ub.edu\/ossma\/en\/wp-json\/wp\/v2\/tags?post=5503"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"Platja](\"https:\/\/www.ub.edu\/ossma\/wp-content\/uploads\/2019\/04\/platja.jpg\")
