Rice samples were collected from main grain producing areas of Jiangxi Province for testing the concentration of DDTs using GC-ECD. The result shows that the concentration ranges from not detected to 0.1474 mg/Kg, the total detection rate is as large as 75.41% and the highest detection rate among four metabolites appeared in p,p'-DDE and the total, exceeding standard rate by 19.67% totally. In view...
Axial and ventral muscle from 10 each species of freshwater and marine fish purchased from markets in Hong Kong were analyzed for dichlorodiphenyltrichloroethane (total DDTs including DDE, DDD and DDT) and polycyclic aromatic hydrocarbons (PAHs). Among the 10 freshwater fish species, rice field eel (Monopterus albus) showed significantly higher levels of DDTs in both ventral (125ng/g wet wt) and axial...
