EVALUATION OF THE RELATIONSHIP BETWEEN TOTAL PESTICIDE LEVELS AND GREENHOUSE PROPERTIES AND PESTICIDE LEVELS IN GREENHOUSE AGRICULTURAL SOIL

Öz

Organochlorine Pesticides (OCPs) are persistent in nature and tend to accumulate in the soil. It has started to attract attention in recent years due to its negative effects on the environment and human health. In greenhouse cultivation, which is the first point where OCPs join the food chain, it is extremely important to determine their levels. In this study, OCP levels were measured in 24 plastic and 24 glass-covered greenhouses and correlated with greenhouse properties data obtained from the questionnaire applied to greenhouse owners. The mean value of total OCP (Σ17OCP) measured in all greenhouses was calculated as 21.34 ng/g. When the samples taken in greenhouses in two different seasons, summer and winter, were examined, Σ17OCP Summer: 12.99 ng/g, while Σ17OCP winter: 33.86 ng/g. The highest Σ17OCP level was 181.10 ng/g and the lowest Σ17OCP level was 3.31 ng/g. As a result of the comparison of the total OCP levels with the amount of pesticides used in the greenhouses and the ventilation, the direct effect of the spraying and ventilation criteria on the total OCP level was determined. It is recommended to provide necessary training for more conscious use of pesticides and to increase the amount of ventilation, especially in winter.

SERA ZİRAİ TOPRAĞINDA TOPLAM PESTİSİT SEVİYELERİ VE SERA ÖZELLİKLERİ İLE PESTİSİT SEVİYELERİ ARASINDAKİ İLİŞKİNİN DEĞERLENDİRİLMESİ

Öz

Organoklorlu Pestisit(OCP)’ler doğada kalıcı özelliktedir ve toprakta birikme eğilimi gösterir. Çevreye ve insan sağlığına olan olumsuz etkilerinden dolayı son yıllarda dikkat çekmeye başlamıştır. OCP’lerin besin zincirine katıldığı ilk nokta olan sera yetiştiriciliğinde, seviyelerinin tespit edilmesi son derece önem arz etmektedir. Bu çalışmada 24 Plastik, 24 cam kaplı serada OCP seviyeleri ölçülmüş ve sera sahiplerine uygulanan anketten elde edilen sera özellikleri verileri ile ilişkilendirilmiştir. Bütün seralarda ölçülen toplam OCP (Σ17OCP) ortalama değeri 21,34 ng/g olarak hesaplanmıştır. Seralarda yaz ve kış olmak üzere iki farklı mevsimde alınan örnekler incelendiğinde Σ17OCP Yaz: 12,99 ng/g iken Σ17OCP kış: 33.86 ng/g ölçülmüştür. En yüksek Σ17OCP seviyesi 181,10 ng/g ve en düşük Σ17OCP seviyesi 3,31 ng/g olarak ölçülmüştür. Toplam OCP seviyeleri ile seralarda kullanılan ilaç miktarları, havalandırmanın kıyaslanması sonucunda ilaçlama ve havalandırma kriterlerinin toplam OCP seviyesine doğrudan etkisi tespit edilmiştir. Bu sebeple, ilaç kullanım miktarları konusunda daha bilinçli kullanım için gerekli eğitimlerin verilmesi ve özellikle kış mevsimde, havalandırma miktarının arttırılması önerilmektedir.
