• Abstract:

  Objective: To carry out a study on environmental toxicity by means of ecotoxicological tests of toothpastes containing hydroxyapatite, in order to verify whether there are harmful effects caused by the interaction of the contaminating chemical agent with organisms.

  Methodology: The HA toothpastes used in this study contain similar formulas, the difference being that cream A was calcined at 900ºC and contains 10% HA, cream B at 600ºC and contains 10% HA and cream C was not calcined and contains only 5% HA. Statistical analysis of variance was used to check the influence of the concentrations on the organisms Daphnia magna and Euruca sativa.

  Relevance: there is little research on pollutants present in toothpastes and the work provides subsidies for public managers to seek compliance with the New Legal Framework for Sanitation of 2020. 

  Results: with the help of ANOVA analysis, it was found that in the acute tests with Euruca sativa there were abnormal effects on the test organism and it was found that what affects root growth is the type of toothpaste and not the concentration of HA. In the acute test with Daphnia magna, it was found that what affects mortality is the concentration and not the type of toothpaste. As for the chronic toxicity on the organisms, a reduction of around 68.18% in the average fecundity in relation to the control can be observed for the FGC 900-10% cream, 67.08% for the FGC 600-10% cream and 71.65% for the FGH - 5% cream. The organism Daphnia magna proved to be more sensitive than the organism Euruca sativa.   

  Social contributions: the work shows the impact of toothpaste on water quality parameters, so it is hoped that a large part of the population will soon be served by sewage networks and treatment plants with state-of-the-art technologies, so that all chemical compounds can be treated before they are discharged, reducing the harmful effects on the environment and so that we can have healthier bodies of water.
