“…38 Em geral, os pesticidas são estáveis em pH ácido, porém alguns compostos, por exemplo, imazalil e tiabendazol, apresentam baixos percentuais de recuperação quando em pH ácido, devido ao fato de estarem protonados e solubilizados na fase aquosa, não sendo recuperados na etapa de partição. As frutas e os vegetais apresentam um pH natural que varia entre 2,5 e 6,5.…”

“…A total of 2223 samples comprising 700 vegetables and 1523 fruits collected from general stores and wholesale shops were analysed for 100 pesticide residues of insecticides and fungicides with GC equipped with different detectors (ECD, NPD, FPD). Fresh foodstuffs from El Ejido, Almeria, Spain were collected from September 2001 to July 2002 to monitor 81 multiclass pesticides (organophosphorus, organochlorines and pyrimidine) in approximately 4000 vegetable samples by Arrebola et al (Arrebola, 2003).…”
