Abstract
Cilj: Cilj istraživanja bio je ispitati mogućnost primjene reagensa malih čestica (engl. Small Particle Reagent – SPR) na staklu koje je bilo uronjeno u morsku vodu, u odnosu na protok vremena od uranjanja predmeta te utvrditi kvalitetu vizualiziranih tragova. Metode: U istraživanju su prikupljeni uzorci otiska palca desne ruke od 32 punoljetne osobe (16 muškaraca i 16 žena). Ukupno 192 uzorka, odnosno šest otisaka svake osobe, ostavljeno je na predmetnim stakalcima koji su uronjeni u plastične posude s morskom vodom. Nakon protoka vremena od 1, 2, 7, 14, 21, i 28 dana, po 32 uzorka je izvađeno iz vode i tretirano SPRom. Kvaliteta vizualiziranih tragova ocijenjena je ocjenama od 0 do 4, pri čemu su uzorci ocijenjeni s 3 i 4 označivali one pogodne za identifikaciju. Rezultati: Prvi dan od uranjanja ukupno 75 % uzorka bilo je povoljno za identifikaciju. Drugi dan od uranjanja prolaznu ocjenu dobilo je 81,3 % uzoraka, dok je sedmi dan od uranjanja taj udio pao na34 %. Nakon 28 dana uzorci pogodni za identifikaciju mogli su se vizualizirati na 25 % uzoraka. Demografski profil donora nije bio povezan s kvalitetom vizualiziranih uzoraka (P = 0.775). Zaključak: Kvaliteta vizualizacije uzoraka papilarnih linija SPR-om pada u odnosu na vrijeme koje su oni proveli u morskoj vodi. Najviše otisaka pogodnih za identifikaciju moguće je izazvati unutar prva dva dana od uranjanja uzoraka u vodu, no na određenim uzorcima to je moguće i nakon 28 dana.
Abstract (english)
Aim: To examine the possibility of applying small particle reagent (SPR) on glass immersed in seawater and assess the quality of the developed fingermarks considering the immersion time. Method: A study comprised fingermarks of the right thumb collected from 32 adult persons (16 men and 16 women). A total of 192 samples, i.e., six fingermarks from each participant, were left on microscope slides and immersed in plastic containers with seawater. Thirty-two samples were removed from the water after 1, 1, 2, 7, 14, 21, and 28 days and treated with SPR. We assessed the quality of fingermark development using scores 0 – 4, where scores 3 and 4 indicated those suitable for identification. Results: One day after immersion, 75% of the samples were adequate for identification. Two days after immersion, 81.3% samples received a passing grade, while the proportion of identifiable fingermarks dropped to 34% after seven days. After 28 days of immersion, 25% of developed fingermarks were adequate for identification. The demographic profile of the donor did not affect the quality of developed fingermarks (P = 0.775). Conclusion: The quality of developed fingermarks has dropped by increasing the immersion time.The highest proportion of developed fingermarks that are adequate for identification was obtained on the first and second days after immersion. In some samples, identifiable fingermarks could be developed up to 28 after the immersion.
