Experts from Harvard T.H. Chan School of Public Health say that more should be done to limit plastic pollution around the world.<\/p>\n<p class=\"has-block-animation has-fly-in-animation\">In an Oct. 15 JAMA Insights article, <a href=\"https:\/\/hsph.harvard.edu\/profile\/shruthi-mahalingaiah\/\" rel=\"nofollow noopener\" target=\"_blank\">Shruthi Mahalingaiah<\/a>, Mark and Catherine Winkler Associate Professor of Environmental, Reproductive, and Women\u2019s Health, <a href=\"https:\/\/hsph.harvard.edu\/profile\/kari-c-nadeau\/\" rel=\"nofollow noopener\" target=\"_blank\">Kari Nadeau<\/a>, John Rock Professor of Climate and Population Studies, and <a href=\"https:\/\/hsph.harvard.edu\/profile\/david-c-christiani\/\" rel=\"nofollow noopener\" target=\"_blank\">David Christiani<\/a>, Elkan Blout Professor of Environmental Genetics, gave an overview of the extent of pollution from microplastics and their known and potential health impacts. They noted:<\/p>\n<p>Plastics production jumped from 234 million tons in 2000 to 435 million tons in 2020 and is expected to jump by another 70% by 2040;<\/p>\n<p>Plastics contain some highly toxic chemicals such as flame retardants, per- and polyfluoroalkyl substances (PFAS), and phthalates that can migrate into the environment and into human bodies;<\/p>\n<p>Microplastics have been found in many foods, beverages, drinking water sources, clothing pieces, cosmetics, and other personal care products;<\/p>\n<p>Microplastics\u2019 unique structure enables them to act as a vehicle for contaminants;<\/p>\n<p>Studies have shown that microplastic exposure can lead to damage to cells, DNA, and the immune response;<\/p>\n<p>Microplastics have been found in many human tissues, and their concentrations in tissues appear to be increasing over time; and,<\/p>\n<p>Observational studies have shown an association of microplastics with increased risk of heart attack, stroke, dementia, or early death.<\/p>\n<p class=\"has-block-animation has-fly-in-animation\">The authors noted that although there are many local and national policies aimed at limiting plastic pollution, there are few international agreements in place to do so. They wrote, \u201cInternational cooperation to limit plastic pollution and to find environmentally safe plastic alternatives is needed.\u201d<\/p>\n<p class=\"has-block-animation has-fly-in-animation\">Read the JAMA Insights article: <a href=\"https:\/\/jamanetwork.com\/journals\/jama\/fullarticle\/2839990\" target=\"_blank\" rel=\"noopener nofollow\">Microplastics and Human Health<\/a><\/p>\n<p>Learn more<\/p>\n<p class=\"has-block-animation has-fly-in-animation\"><a href=\"https:\/\/hsph.harvard.edu\/news\/microplastics-a-growing-challenge-to-health-and-the-environment\/\" rel=\"nofollow noopener\" target=\"_blank\">Microplastics a growing challenge to health and the environment<\/a> (Harvard Chan School news)<\/p>\n<p>\nLast Updated<\/p>\n<p>\nFeatured in this article\n<\/p>\n<p>\t\t\t\t\t\t<a href=\"https:\/\/hsph.harvard.edu\/profile\/shruthi-mahalingaiah\/\" class=\"wp-block-hsph-featured-people-card__link\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n\t\t\t\t\t\t\tShruthi Mahalingaiah\t\t\t\t\t\t<\/a><\/p>\n<p>\t\t\t\tMark and Catherine Winkler Associate Professor of Environmental Reproductive and Women\u00bfs Health<\/p>\n<p>\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/connects.catalyst.harvard.edu\/Profiles\/profile\/Modules\/CustomViewPersonGeneralInfo\/PhotoHandler.ashx?NodeID=1252949\" alt=\"Shruthi Mahalingaiah\" width=\"160\" height=\"160\"\/><\/p>\n<p>\t\t\t\t\t\t<a href=\"https:\/\/hsph.harvard.edu\/profile\/kari-c-nadeau\/\" class=\"wp-block-hsph-featured-people-card__link\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n\t\t\t\t\t\t\tKari C Nadeau\t\t\t\t\t\t<\/a><\/p>\n<p>\t\t\t\tJohn Rock Professor of Climate and Population Studies<\/p>\n<p>\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/connects.catalyst.harvard.edu\/Profiles\/profile\/Modules\/CustomViewPersonGeneralInfo\/PhotoHandler.ashx?NodeID=206527297\" alt=\"Kari C Nadeau\" width=\"160\" height=\"160\"\/><\/p>\n<p>Get the latest public health news<\/p>\n<p class=\"has-text-align-center has-block-animation has-fly-in-animation\">Stay connected with Harvard Chan School<\/p>\n","protected":false},"excerpt":{"rendered":"Home \/ News \/ Microplastics are everywhere and can harm human health, say experts Hide caption Show caption&hellip;\n","protected":false},"author":2,"featured_media":87265,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[273,111,139,69,147],"class_list":{"0":"post-87264","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-environment","8":"tag-environment","9":"tag-new-zealand","10":"tag-newzealand","11":"tag-nz","12":"tag-science"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/87264","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/comments?post=87264"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/87264\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media\/87265"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media?parent=87264"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/categories?post=87264"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/tags?post=87264"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
