Bu çalışmada Giresun ilinde farklı oto yıkama merkezlerinin atik su içeriğindeki kadmiyum (Cd), arsenik (As), kurşun (Pb), nikel (Ni) ve krom (Cr) metalleri indüktif eşleşmiş plazma kütle spektrometresi (ICP-MS) ile tayin edilmiştir. Bu amaçla, belirlenen istasyonlardan toplanan su numuneleri, 0,45 µm membran filtreden süzülmüş ve tayin öncesinde asitlendirilerek metal içerikleri analiz edilmiştir. Elde edilen veriler Dünya Sağlık Örgütü (WHO), Amerika Birleşik Devletleri Çevre Koruma Ajansı (EPA) ve Türk Standartları Enstitüsü’nün içme ve kullanım sularında metal içerikleri için belirlenen sınır değerler kullanılarak tartışılmıştır. Analiz edilen atık su numuneleri için metal konsantrasyonları; As (15,2±0,3 µg L-1), Pb (26,9±0,4 µg L-1), Ni (31,5±1,1 µg L-1) ve Cr (9,8±0,4 µg L-1) olarak tespit edilmiştir. Ölçümlerin doğruluğu, numune matriksine ekleme/geri kazanım yöntemi kullanılarak belirlenmiştir. Elde edilen geri kazanım değerleri %88-108 arasında bulunmuştur.
