Over the period of five years, no significant worsening of the Oder River water quality has been observed with respect to the total organic carbon content, however, an increase in the concentrations of specific organic contaminants from the PFAS group was observed. An intense seasonal algae growth was found in spring and late summer, and the number of algae has increased with time. Diatoms are the most abundant algae type. Water from the Oder River contains large amounts of biogens (nitrates and phosphates), which promote microorganism growth in water.<\/p>\n","protected":false},"featured_media":0,"parent":0,"menu_order":0,"template":"","meta":[],"tags":[3994,3992,3991,3993],"tematyka":[591],"class_list":["post-20906","artykul","type-artykul","status-publish","hentry","tag-algae","tag-micropollutants","tag-oder-river","tag-perfluoroalkyl-acids","tematyka-environmental-protection","has-post-title","has-post-date","has-post-category","has-post-tag","has-post-comment","has-post-author",""],"ptb_metabox":{"ptb_artykul_text_1":["MA\u0141GORZATA WOLSKA","HALINA URBA\u0143SKA-KOZ\u0141OWSKA"],"ptb_artykul_text_2":"10.36119\/15.2023.12.22","ptb_artykul_numer_miesi_cznika":"12\/2023 Instal p.129-133","ptb_artykul_info_autor":"Ma\u0142gorzata Wolska DSc., prof of WUST https:\/\/orcid.org\/ 0000-0003-3627-4778,\r\nHalina Urba\u0144ska-Koz\u0142owska MSc., Eng., https:\/\/orcid.org\/ 0000-0001-9137-6510 \u2013 Wroclaw University of Science and Technology, Faculty of Environmental Engineering, Wybrze\u017ce Wyspia\u0144skiego 27, 50-370 Wroc\u0142aw, Poland, e-mail: halina.urbanska@mpwik.wroc.pl Corresponding author: Ma\u0142gorzata Wolska e-mail: malgorzata.wolska@pwr.edu.pl","ptb_artykul_orcid":["0000-0003-3627-4778","0000-0001-9137-6510"]},"ptb_taxonomy":{"post_tag":[{"term_id":3994,"name":"algae","slug":"algae","term_group":0,"term_taxonomy_id":3994,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3992,"name":"micropollutants","slug":"micropollutants","term_group":0,"term_taxonomy_id":3992,"taxonomy":"post_tag","description":"","parent":0,"count":4,"filter":"raw"},{"term_id":3991,"name":"Oder River","slug":"oder-river","term_group":0,"term_taxonomy_id":3991,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3993,"name":"perfluoroalkyl acids","slug":"perfluoroalkyl-acids","term_group":0,"term_taxonomy_id":3993,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"}],"tematyka":[{"term_id":591,"name":"Environmental Protection","slug":"environmental-protection","term_group":0,"term_taxonomy_id":591,"taxonomy":"tematyka","description":"","parent":0,"count":16,"filter":"raw"}]},"ptb_featured_image":null,"builder_content":" Read more <\/a>","_links":{"self":[{"href":"https:\/\/informacjainstal.com.pl\/en\/wp-json\/wp\/v2\/artykul\/20906","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/informacjainstal.com.pl\/en\/wp-json\/wp\/v2\/artykul"}],"about":[{"href":"https:\/\/informacjainstal.com.pl\/en\/wp-json\/wp\/v2\/types\/artykul"}],"wp:attachment":[{"href":"https:\/\/informacjainstal.com.pl\/en\/wp-json\/wp\/v2\/media?parent=20906"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/informacjainstal.com.pl\/en\/wp-json\/wp\/v2\/tags?post=20906"},{"taxonomy":"tematyka","embeddable":true,"href":"https:\/\/informacjainstal.com.pl\/en\/wp-json\/wp\/v2\/tematyka?post=20906"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
