Three eco-friendly and cost-effective analytical methods were developed and optimized for quantitative analysis of some veterinary drug residues in production wastewater samples.

The present study investigates a synergistic adsorption/photodegradation technique catalyzed by a pectin/chitosan/zinc oxide (Pec/CS/ZnO) nanocomposite for the removal of carbamazepine (CBZ) in aqueous solutions under direct sunlight.

Organochlorine insecticides residues (α-HCH, β-HCH, Lindane, HCB, Aldrin, Heptachlor, Chlordane, total DDT, Endrin and Methoxychlor) were analyzed in 75 samples of raw milk, sour cream and cooking buttercollected from Beni-Suef Governorate-using gas chromatography with electron capture detector (GC-ECD). The results indicated that all the examined samples were accepted except three butter samples showed residue levels exceeded the Maximum Residues Levels (MRLs).
