| Abstract | The toxicological impacts of the increasing number of synthetic compounds present in the aquatic environment are assessed predominantly in laboratory studies where test organisms are exposed to a range of compounds. Protozoan cells are often used as bioindicators for the presence of xenobiotics. In this work, we study the cytotoxicity of three newly synthesized amidophosphonates (AP1, AP2, and AP3) on an alternative cellular model: the protist ciliate Paramecium tetraurelia. We also used an analogue marketed in Algeria for comparison: chlorpyriphos ethyl. The LC50 values were determined for these protozoa after a series of preliminary toxicity tests and used for the rest of our study: 30 μM for AP1, AP2 for 25 μM, 15 μM for AP3, and 10 μM for chlorpyriphos ethyl. The growth kinetics of the protozoa are perturbed and this is confirmed by the percentage of response, and we also demonstrated a significant decrease in GSH thus confirming the toxicity of the tested compounds. According to the results of our study, it has been proven that amidophosphonates AP1, AP2, AP3 show less cytotoxic effects than chlorpyriphos ethyl. |

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.
