Özet

Bu araştırma Afyonkarahisar'da tarım alanlarını sulamak için kullanılan atık sularda helmint kontaminasyonunun belirlenmesi amacıyla yapılmıştır. Araştırmada, insan ve hayvansal kaynaklı atıkların karıştığı akarsudan tarımsal amaçlı su kullanan 10 kırsal alan seçilmiştir. Eylül 2004-Ağustos 2005 tarihleri arasında iki haftada bir bu alanlara gidilerek toplam 240 su örneği alınmıştır. Toplanan arıtılmamış su örneklerinin 32'sinde (%26,7) helmint yumurtası tespit edilirken, arıtılmış su örneklerinde herhangi bir helmint veya gelişim formuna rastlanmamıştır (p

Abstract

This research was performed in order to examine helminth contaminated wastewaters used in agriculture in Afyonkarahisar. Ten rural areas were selected that used water for agricultural purposes from a creek contaminated with human and animal wastes. Between September 2004 and August 2005, these areas were visited once every two weeks, and a total of 240 water samples were collected. Out of untreated water samples, 32 samples (26.70%) had helminth eggs, whereas there were neither helminths nor developmental stages of helminths (p< 0.001) in treated water samples. Cestode eggs were seen in 10.00% of untreated water sam-ples and nematode eggs were seen in 16.70%. Out of the helminth eggs, 13 (40.60%) were hookworm eggs; 6 (18.75%), Taenia spp.; 5 (5.60%), Ascaris lumbricoides; 3 (9.40%), Hymenolepis diminuta; 3 (9.40%), H. nana; and 2 (6.25%), Toxocara spp. In conclu-sion; the creek was found to be contaminated by helminths originating from human and animal wastes in Afyonkarahisar. This type of water presents a risk for human and animal health and contaminated waters, therefore, should be avoided in irrigation of vegeta-bles and fruit consumed raw.
