Abstract
The study was conducted to analyze the amount of residue of six commonly used pesticides (e.g. chlorpyriphos, quinalphos, diazinon, acephate, dimethoate and fenitrothion) in vegetables viz., hyacinth bean and eggplant samples collected from local market of nine different locations viz. Cumilla, Bogura, Rangpur, Rajshahi, Khagrachari, Cox’s bazaar, Barishal, Jamalpur and Dhaka for the comparison between the detected residue level with maximum residue limit (MRL) set by European Union. Among 36 analyzed samples of hyacinth bean six samples (16.67%) were contaminated with chlorpyriphos (0.082 mg/kg) and dimethoate residue (0.192 mg/kg - 0.961 mg/kg), all of them were above maximum residue limit. Out of 36 analyzed samples of eggplant 3 samples (8.33%) were contaminated with quinalphos (0.081mg/kg) and dimethoate residue (0.032 mg/kg - 0.217 mg/kg) which were above MRL. Most of the samples contained with dimethoate residue in both the vegetables. The presence of pesticide residue exceeding MRL in vegetables is harmful to human and other living organisms. Analyzed samples of Cumilla, Bogura, Rangpur and Rajshahi showed pesticide residue (i.e. dimethoate, chlorpyriphos and quinalphos) over MRL but the samples of other five locations like Cox’s bazar, Khagrachari, Barishal, Jamalpur and Dhaka did not show any detectable residue which might safe for consumption.

The analytical results of both the vegetable samples for the detection of pesticide residue have been summarized in Tables 1 and 2
A total of 36 analyzed samples of hyacinth bean collected from local market of nine different locations viz. Jessore, Cumilla, Norsingdi, Bogura, khagrachari, cox’s bazaar, Mymensingh, Rangpur, Dinajpur, Ishurdi, Gazipur and Dhaka revealed that 16.67% samples were contaminated with dimethoate and chlorpyriphos residue
Summary
To grow more agricultural production the use of agrochemicals is increasing rate at present. More intensive vegetable production is the common reliance of most vegetable producers on heavy application of pesticide (Hossain et al, 2000). Among the vegetables i.e. hyacinth bean and eggplant grown in Bangladesh, are nutritious, valuable and very popular to consumers. It has been reported that in eggplant and hyacinth bean the attack of insect pests are severe and farmers sprayed pesticides quite frequently even every day The improvement of the food production technology and the demands of the new markets for better products both in quality and quantity have been made among others with intensive uses of pesticides for productivity warranty (Trevisan et al, 2004). Very little references are available on the presence of pesticides in vegetables in Bangladesh (Khatoon et al, 2004; Ahmed et al, 2013).
