Which pesticide was found most commonly in the vegetable samples?
|
Chlorpyrifos |
|
Chlorpyrifos was detected in 66% of the analyzed green leafy vegetable samples |
chlorpyrifos were preferred by vegetable growers due to their lower cost compared to newer alternatives like imidacloprid . |

What percentage of the vegetable samples tested were found to contain no detectable pesticides?
|
16% |
|
16% of the collected green leafy vegetable samples were found to be negative for the selected pesticides |
The study notes that for these sixteen percent of samples where no pesticide was detected, the reason could be either that no pesticides were used or that the pesticides used were beyond the detection limit of the method. |

According to the study, why might vegetable growers prefer other pesticides over Imidacloprid (ICP)?
|
ICP is more expensive. |
|
The pesticide dealer survey clearly showed that conventional pesticides organophosphates were available at lower prices (around ten times) in comparison to that of imidacloprid. |
Despite imidacloprid being considered a good alternative for those pesticides which cause toxicity due to its lower toxicity profile , the economic factors clearly outweighed the safety benefits for local vegetable growers. |

What is the primary benefit of using hyperthermia in cancer treatment?
|
It kills cancer cells with minimal damage to normal cells. |
|
The primary benefit of using hyperthermia in cancer treatment is that elevated body temperature can damage and kill cancerous cells with minimal injury to normal cells. |
The technique offers a significant advantage because hyperthermia neglects the use of chemicals or harmful radiations while still providing effective cancer treatment. This makes it a valuable addition to conventional therapies, with the study noting that hyperthermia appears to be the fourth pillar besides surgery, radiotherapy and chemotherapy. |

|
Reaching and maintaining the required temperature in the target area. |
|
the main challenge of using hyperthermia in cancer treatment is attaining temperature above the systemic temperature 37°C in a specified target volume/area |
To reach the elevated temperature approximately 42°C at least in some parts of the body tumors require a power density of approximately 20–40 W/kg at the target region . This is significantly higher than normal basal metabolism of human which is above 1 W/kg |
