A new strategy is proposed for verifying if recovery factor is constant and independent of the real analyte content of samples. A signal-recovery function has been developed on the basis of measurement of spiked test samples before and after a pre-treatment step and considering, as starting point, a recent IUPAC recommendation which distinguishes between two terms--recovery factor, R, and appar...

OBJECTIVE Improper land disposal of hazardous waste can result in leaching of hazardous constituents which may contaminate ground and surface water leading to adverse impact on human health and environment consequences. The present study utilized mammalian cell culture for the genotoxicity assessment of waste and its leachate. METHODS Genotoxic potential and chemical analysis of pesticide der...

1. Study corroborates our analysis done in October-November, 2009 that the UCIL site is heavy contaminated with chlorinated benzene compounds, organochlorine pesticides, carbmate pesticides (Carbaryl and Aldicarb. It also confirms that this contamination has nothing to do with the gas accident, but is caused by UCC/UCIL dumping and disposing off waste indiscriminately on the site. All pesticide...

Trong nghiên cứu này chúng tôi đã xây dựng quy trình định lượng đồng thời 9 chất tồn dư bảo vệ thực vật trong một số loại rau quả như Difenoconazole, Hexaconazole, Emamectin benzoate, Indoxacard, Acetamiprid, Carbaryl, Ethoprophos, Dimethoat, Carbosulfan bằng phương pháp khối phổ (Mass Spectrometry-MS), tiến hành phân tích trên máy LC - MS/MS. Điều kiện gồm cột sắc ký: tốc độ dòng 0.1 mL/phút, ...
