A rationale on why the application would be effective in reducing mortality and injuries from hazardous events has also been proved statistically.
Download Edit. Sporadic monitoring, amalgamated with the paucity of well-grounded and inexpensive testing devices has created a need for the citizens to address the issue themselves. Impelled by promising results from a survey, FoodAlytics, a portable, economical and non-contact formalin detection system has been developed using locally sourced COTS components. Integrated with our own android application and bundled with the Grove VOC HCHO gas sensor, a recent innovation, our system has been able to detect up to 50 ppm of formalin.
Polynomial regression, linear regression and the Levenberg-Marquardt algorithm, three supervised machine learning algorithms have been incorporated in our system to accurately predict the correct concentration of formalin at all temperatures. By applying logistic regression and support vector machines, our system is also able to correctly classify between artificially added and naturally formed formalin.
The widespread adulteration of fresh fruits, vegetables and fish with harmful concentrations of formalin has become a severe issue in Bangladesh due to the health hazards associated with it [1][2]. Excessive concentrations of formalin has been found in almost all fruits available in the local market, thanks to lack of sufficient monitoring and raids [3].
Analogous to this issue, the authors decided to conduct a survey on random subjects in and around Dhaka city to find out what our citizens think should be the impeccable solution to this problem. Figure 1 shows partial results of the survey.
