Degradation dynamics and dissipation kinetics of an imidazole fungicide (Prochloraz) in aqueous medium of varying pHLaboratory degradation studies were performed in water at pH 4.0, 7.0 and 9.2 using Prochloraz (450 EC) formulation at the concentration of 1.0 (T1) and 2.0 (T2) μg/mL. Water samples collected on 0 (2 h), 3, 7, 15, 30, 45, 60 and 90 days after treatments were processed for residue analysis of Prochloraz by HPLC-UV detector. In 60 days, dissipation was 89.1-90.5% at pH 4.0, 84.1-88.2% at pH 7.0, and 92.4-93.8% at pH 9.2 in both treatments. The results indicate that at pH 7.0 the degradation of Prochloraz was much slower as compared to other two. Between pH 4.0 and 9.2 the degradation of compound is little faster at pH 9.2. The half-life periods observed were 18.35 and 19.17 days at pH 4.0, 22.6 and 25.1 days at pH 7.0 and 15.8 and 16.6 days at pH 9.2 at T1and T2doses respectively.

Various prevalence studies onLeptospirain animals and humans, as well as environmental samples, had been conducted worldwide, including Malaysia. However, limited studies have been documented on the presence of pathogenic, intermediate, and saprophyticLeptospirain selected animals and environments. This study was therefore conducted to detectLeptospiraspp. in rats, soil, and water from urban areas of Sarawak using the polymerase chain reaction (PCR) method. A total of 107 rats, 292 soil samples, and 324 water samples were collected from April 2014 to February 2015. PathogenicLeptospirawas present in 5.6% (6/107) of rats, 11.6% (34/292) of soil samples, and 1.9% (6/324) of water samples. IntermediateLeptospirawas present in 2.7% (8/292) of soil samples and 1.9% (6/324) of water samples. SaprophyticLeptospirawas present in 10.3% (11/107) of rats, 1.4% (4/292) of soil samples, and 0.3% (1/324) of water samples. From this study, 76Leptospiraspp. were isolated. Based on DNA sequencing, the dominantLeptospiraspp. circulating in urban areas of Sarawak are pathogenicLeptospira noguchii, intermediateLeptospira wolffiiserovar Khorat, and saprophyticLeptospira meyeri, respectively. Overall, this study provided important surveillance data on the prevalence ofLeptospiraspp. from rats and the environment, with dominant local serovars in urban areas of Sarawak.
