Kuhn) kontinente guztietan, Antartikan izan ezik, dagoen landare-espezie kosmopolita da, eta munduko landare ugarienetakoa dela esaten da. Izaera oportunista eta inbaditzailea du, eta sarri ugaritzen da utzitako, moztu berri edo erretako eremuetan. Ohikoa da zuhaiztietan, baso-bazterretan, berriki soilduta zuhaitz eremuetan eta atzeraka doazen nekazaritza-lurretan.<\/span>\u00a0<\/span><\/p>\n

Iratze arrunta oso ezaguna da bere propietate toxiko eta kartzinogenikoengatik, eta animaliengan modu naturalean minbizia eragiteko gai den landare bakarrenetakoa da. XIX. Mendeaz geroztik dokumentatu izan dira ganaduan izan dituen eragin toxikoak. Ondorioz, iratzea MOE\/IARCen zerrendan sartu da, gizakientzat agian kartzinogenoa izan daitekeen elikadura-osagai gisa. Bere toxinei buruzko ikerketa sakonak 1983an ptakilosidoa (PTA) bere toxina nagusi bezala identifikatzera eraman zuen, nahiz eta ezegonkorra izan.<\/span>\u00a0<\/span><\/p>\n

PTA oso disolbagarria da uretan, eta lixibiatu egin daiteke lurzoruaren goiko horizontetik gainazaleko eta lurpeko uretarantz. Gizakiak edateko uraren bidez izan dezakeen esposizioa dela eta, PTA azaleratzen ari den kutsatzailetzat hartzen da (Skrbic et al., 2020). Hidrolizatu egiten da B pterosina (PtB) eratzeko, konposatu hidrofobikoagoa eta ez-toxikotzat jotzen dena (Yamada et al., 2007). PtB agertzeak PTA egon dela adierazten du, eta iratzeko landare-materialean, lurrean eta uretako hidrolisi-produktu gisa aurki daiteke.<\/span>\u00a0<\/span><\/p>\n

Berriki, Irlanda, Italia eta Danimarka bezalako herrialdeetan PTAk sortutako giza kontsumorako uren kutsadurarekiko kezka areagotu egin da (O\u2019Driscoll et al., 2016; Rasmussen et al., 2003; Zaccone et al., 2014). Gaur egun, Europar Batasunean ez dago edateko uraren PTA mailei buruzko erregulaziorik. LIFE URBASOk demostrazio arroetako ur gordinaren PTA eta PtB mailak monitorizatzen ditu bi astetik behin, oinarri-oinarrizko mailak ezagutu asmoz.<\/span>\u00a0<\/span>[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_empty_space][vc_single_image image=”5015″ img_size=”full” qode_css_animation=””][vc_empty_space][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern”][vc_column][vc_empty_space][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”full_width” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern”][vc_column][vc_separator type=”normal”][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"
