Address the issues raised by the reviewer 23 Typically, more than one insecticide is applied to a field to protect plants from pests. This multi-residue method provides an accurate and sensitive solution to simultaneously detect various pesticides in agricultural products. - nonsense; the application does not detect anything. It may remove/ destroy/ address the various pests. Please clarify. 28 The retention time ranged from 3.71 to 27.65 min. 30 the range 0.00315 to 0.05 <mu>g/mL and 0.01 to 0.165 <mu>g/mL, respectively, both of which are 31 Recoveries of chlorpyrifos in sweetcorn and soil ranged between 85% and 106%, whereas the 34 this method may be suitable for detecting pesticide residues in 54 trace amounts, can result in serious adverse effects on health (…). 56 Therefore, it is necessary to develop programs for monitoring pesticide 57 These programs could help determine the magnitude of the contamination problem and aid in identifying a method to solve the problem. 67 regulated to ensure residues in food are below levels considered safe for human 73 2011). However, it is particularly harmful toward humans and non-target organisms (…). - non-target organisms, such as? 74 Chlorpyrifos has been detected in surface water (…) … 79 Sweet corn (…), a vegetable or fruit, … - decide which it is 107 Various pesticide standards (in acetone) were prepared in the range 0.00625 to 2 <mu>g/mL. 110 Sweet corn samples (ca. 400 g) were blended thoroughly to obtain a 111 Samples (20 g) were placed in a 250 mL 115 the combined extracts were transferred to a separation funnel, and the aqueous phase 129 an HP 6890 series II with an autosampler 7683 series (Agilent, CITY, COUNTRY). 136 Nitrogen-phosphorous detection (NPD) was used at 280 ºC with hydrogen (3 mL/ min) and synthetic air (60 mL/ min). Representative chromatograms were … 139 Blank sweet corn was the control - explain in this context 139 … fortified sweet corn samples at 0.1, 0.5 and 1 <mu>g/g were analysed. - not fortified but spiked and with what? 140 Blank soil was a control, and fortified soil samples at the same concentrations were also analysed. - same issue although not relevant to Food Chemistry etc. etc. 225 using a variety of detection method, such as nitrogen-phosphorus detection (…) (…), … 235 Studies have shown that different solvents, such as n-hexane, petroleum ether dichloromethane, acetonitrile, and acetone or ethyl acetate can be used to extract pesticide residues from fruits and vegetables (all references here). 240 pesticides from fruits and vegetables because its polar, and less volatile and thermally labile. 242 acetate, and the retention times of the pesticides are shown in Table 1. |
