| Abstract | This paper describes a rapid pesticide residues detection method for vegetable samples or water samples based on a mini-colorimeter. The sensors responding signal and condition circuit of the mini-colorimeter are composed of emitting diodes, photodiode receivers and integrated circuit amplifiers. Single chip microprocessor is the core of the system. The concentration(PPM) of pesticides is displayed by 4 nixietubes. A neural network mathematic model is established to calculate the residual concentration of the pesticides. The neural network weigh matrixes are trained with supervised samples of 0ߝ6 PPM omethoate and Chlorsalicylamide. The pesticide residues are detected for greengrocery samples. Using this meter, it takes one minute to measure the organophosphates pesticide residues in a greengrocery sample or Chlorsalicylamide in water sample. This meter can be used in other pesticides detection with the help of suitable chromogenic agents. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
