Toxicity and genotoxicity tests were performed on root cells of Allium cepa in order to evaluate wastewater quality following an ECF cellulose bleaching process. The results revealed a toxic effect of the effluent, with inhibition of meristem growth and generally lower values of metaphase, anaphase and telophase indices at pH 10.5 than pH 7 for all effluent concentrations. The genotoxicity effect was different from the toxic effect given that the micronucleus and the chromosomal aberration tests in anaphase-telophase cells were low over all ranges of the studied effluent concentrations.Keywords: Allium cepa, toxicity, genotoxicity, ECF bleaching effluent, Kraft cellulose.Genotoxicidade e toxicidade em Allium cepa L.: avaliação da qualidade do efluente no processo de branqueamento da celulose ResumoOs testes de toxicidade e genotoxicidade foram realizados em células da raiz de Allium cepa, a fim de avaliar a qualidade do efluente na sequência de um processo de branqueamento de celulose ECF. Os resultados revelaram um efeito tóxico do efluente, com inibição de crescimento do meristema e valores geralmente baixos de metáfase, anáfase e índices de telófase, a pH 10,5 e pH 7, para todas as concentrações do efluente. O efeito de genotoxicidade foi diferente do efeito tóxico, uma vez que o micronúcleo e os testes de aberrações cromossômicas em anáfase-telófase das células foram baixos em todas as gamas de concentrações do efluente estudado.Palavras-chave: Allium cepa, toxicidade, genotoxicidade, branqueamento por sequências ECF, Kraft celulose.

“…Although some studies show that these techniques are more sensitive in identifying changes, the question is whether these changes are significant or meaningful for the organism and will translate to more relevant adverse effects. Over several years of the EEM program, a critical effect size was developed to interpret the severity of responses [70] for all the endpoints. This is important to develop for these molecular endpoints, so that agreement can be reached regarding how big of a change is needed before further monitoring or corrective action/remediation is warranted.…”

“…Temporal differences across sites may also be a result of differences in habitat conditions (discussed in Recommended parameters to measure and report) among years, highlighting the importance of site characterization. For example, even within reference sites, the coefficient of variation in female white sucker gonad size between years is generally the mean AE 2 standard deviations [70]. Using reference sites to characterize natural variability is necessary to define triggers for more intense monitoring and to discern how big a change is important, 2 required items for a successful EEM program [60].…”

Scientific reviews and studies continue to describe omics technologies as the next generation of tools for environmental monitoring, while cautioning that there are limitations and obstacles to overcome. However, omics has not yet transitioned into national environmental monitoring programs designed to assess ecosystem health. Using the example of the Canadian Environmental Effects Monitoring (EEM) program, the authors describe the steps that would be required for omics technologies to be included in such an established program. These steps include baseline collection of omics endpoints across different species and sites to generate a range of what is biologically normal within a particular ecosystem. Natural individual variability in the omes is not adequately characterized and is often not measured in the field, but is a key component to an environmental monitoring program, to determine the critical effect size or action threshold for management. Omics endpoints must develop a level of standardization, consistency, and rigor that will allow interpretation of the relevance of changes across broader scales. To date, population-level consequences of routinely measured endpoints such as reduced gonad size or intersex in fish is not entirely clear, and the significance of genome-wide molecular, proteome, or metabolic changes on organism or population health is further removed from the levels of ecological change traditionally managed. The present review is not intended to dismiss the idea that omics will play a future role in large-scale environmental monitoring studies, but rather outlines the necessary actions for its inclusion in regulatory monitoring programs focused on assessing ecosystem health.
