Past\u0101v divu veidu da\u013ci\u0146as. Da\u013ci\u0146as, kuru diametrs ir liel\u0101ks par 10 \u00b5m un kuras ir redzamas ar neapbru\u0146otu aci, jo \u012bpa\u0161i saulain\u0101s dien\u0101s, un da\u013ci\u0146as, kas ir maz\u0101kas par PM 10 un ac\u012bm nav redzamas.

Iepriek\u0161 redzamaj\u0101 diagramm\u0101 par\u0101d\u012bts da\u013ci\u0146u iek\u013c\u016b\u0161anas l\u012bmenis organism\u0101 atkar\u012bb\u0101 no to diametra.

Dabiski, ka organisms, pateicoties plau\u0161u skropsti\u0146\u0101m, var izvad\u012bt putek\u013cus. T\u0101s izspie\u017e da\u013ci\u0146as t\u0101l\u0101k uz gremo\u0161anas traktu un izvada t\u0101s gremo\u0161anas proces\u0101. Tom\u0113r da\u017eas iedz\u012bvot\u0101ju grupas ir jut\u012bg\u0101kas. Piem\u0113ram, sm\u0113\u0137\u0113t\u0101jiem ir iev\u0113rojami maz\u0101k plau\u0161u skropstu, t\u0101p\u0113c da\u013ci\u0146u izvad\u012b\u0161ana aiz\u0146em ilg\u0101ku laiku. Astmati\u0137i ir jut\u012bg\u0101ki pret gaisa pies\u0101r\u0146ojumu… <\/p>\n\n

Viens no svar\u012bg\u0101kajiem da\u013ci\u0146u toksicit\u0101tes faktoriem ir biopersistence – laiks, kas nepiecie\u0161ams, lai organisms izvad\u012btu putek\u013cus.<\/p>\n\n

V\u0113l viens faktors ir PM 1. \u0160\u012bs da\u013ci\u0146as ir tik s\u012bkas, ka t\u0101s izk\u013c\u016bst cauri plau\u0161u alveol\u0101m un non\u0101k tie\u0161i asinsrit\u0113. Tas \u012bpa\u0161i attiecas uz cigare\u0161u d\u016bmiem, v\u012brusiem, pestic\u012bdiem u. c. <\/p>\n\n

Visas da\u013ci\u0146as nogulsn\u0113jas. Ta\u010du \u012bpa\u0161i smalku da\u013ci\u0146u gad\u012bjum\u0101 var paiet vair\u0101kas dienas, pirms t\u0101s nogulsn\u0113jas zem\u0113. <\/p>\n\n

Nok\u013c\u016b\u0161anas \u0101trumu nosaka putek\u013cu masa un bl\u012bvums. Jo maz\u0101ka masa, jo ilg\u0101k tie nogulsn\u0113jas un jo jut\u012bg\u0101ki pret gaisa pl\u016bsm\u0101m. <\/p>\n\n

T\u0101tad teor\u0113tiski, ja m\u0113s grib\u0113tu pagaid\u012bt, kam\u0113r nos\u0113\u017eas visi putek\u013ci, mums b\u016btu piln\u012bb\u0101 j\u0101p\u0101rtrauc darbs uz 15 dien\u0101m.
