Pesticides are widely used in agriculture mainly to increase crop yields to cater huge supply of food products for increasing world population as well as to protect crops from pests and control insect-borne diseases. Increased use of pesticides results in contamination of the environment and the excess accumulation of pesticide residues in food products, which has always been a matter of seriou...
Background: The use of pesticides is essential to pests control in horticultural crops for the production of an adequate food supply for an increasing world population and for the control of insect-borne diseases. Therefore, pesticide residues in environment and food have a negative impact on the health of living organisms especially human. In this regard, the present study was carried out for ...
Background and purpose: Organophosphorous insecticides are chemical substances that are widely used globally against plant pests and diseases, led to an increase in farm productivity. On the other hand, their excessive use/misuse especially in the developing countries, their volatility, long-distance transports eventually results in widespread environmental contamination that creating serious a...
A total of 144 Kg of strawberry and 38 soil samples, representing two types of farming production e.g. conventional (C), organic (O), was collected from (Bilbeis and AL-Salhia, New AL-Sharqiya governorate) Egypt. Pesticides residues were determined by gas chromatography with mass selective detector (GC-MSD). This method used to determine 86 pesticide residues with a broad range of physico-chemi...
Cucumber is one of the main vegetables in Iranian food basket. A wide range of pesticides are used for crops protection during the cultivation of vegetables such as cucumber due to heavy pest infestation. Analysis of pesticide residues in food and other environmental commodities have become essential requirement for consumers, producers, and food quality control authorities. This study was aime...
BACKGROUND A wide range of pesticides is applied for crop protection in vegetable cultivation in China. Regulation of pesticide maximum residue limits (MRLs) in vegetables is established but not fully enforced. And pesticide residues in vegetables were not well monitored. This study conducted the monitoring surveys from 2011 to 2013 to investigate the pesticides in vegetables in the northwest r...
Extensive use of chemical pesticides to control pests in developed and developing countries has led to the increase in crop production and decrease in post-harvest losses, which has caused harmful effects on human health. When the amount of pesticides exceeds permissible limits, some measures should be undertaken to reduce their application. In order to control cucumber pests in greenhouse, far...
Tea is an agricultural product of the leaves, leaf buds, and internodes of various cultivars and sub-varieties of the Camellia sinensis plant, processed and vulcanized using various methods. Tea is a main beverage in Iranian food basket so should be free from toxic elements such as pesticides residue. There is no data bank on the residue of pesticides in the consumed black tea in Iran. The pres...
Raw buffalo milk samples from the agroindustrial zone in upper Egypt were analyzed for the presence of organochlorine and organophosphorus pesticides using gas chromatography-mass spectroscopy. Five organochlorine pesticides namely, alachlor, dieldrin, hexachlorobenzene, lindane and methoxychlor and three organophosphorus pesticides chlorpyrifos, malathion, and parathion-methyl were detected in...
