“…Using such a method, it is possible to detect aberrant anaphases, which along with the mitotic index, show the mutagenic potential of the waters examined. Besides, the test may be conducted with plans from the river, which would indicate the actual genotoxic impact for the chronically exposed organism population in the region (Lazutka et al, 2003;Reifferscheid et al, 2008).…”

ABSTRACT. Water resource degradation is one of mankind's greatest worries, as it causes direct and indirect damage to the associated biota. We initiated a water monitoring study in Pelotas Creek in 2003 in order to assess the mutagenic effect of the creek's waters. Allium cepa cells exposed to water samples and a chronically exposed macrophyte were analyzed, through evaluation of the mitotic index, mitotic anomalies, interphase anomalies, and total anomalies. Five points were chosen along the lower course of Pelotas Creek, from which water samples and floating pennywort (Hydrocotyle ranunculoides, Apiaceae) were collected in 2006 and 2007. The enteric bacterium Escherichia coli was found at all sampling points; in the physical-chemical analysis, a few variables exceeded permitted limits, pH (from 6 to 9), chloride (250 mg/L), hardness (from 10 to 200 mg CaCO 3 /L), and conductivity (100 µΩ/cm). There was an increased number of cytogenetic anomalies in exposed A. cepa cells and in the pennywort in 2006 relative to 2007, which may be explained by the increased rainfall, which was three times greater in 2007 at some stations than in 2006.

“…In the in situ assays, transferred indicator plants are used to detect genotoxins in the environment. However, they cannot reveal the actual genotoxic impact on populations chronically exposed in the field and can give false-positive results (Latuzka et al, 2003). These problems can be overcome if standard indicator species permanently growing at the monitoring site are used.…”

“…to the test grounds where they are exposed to the technogenic factors studied. Although this method is very sensitive, it also has some drawbacks (Lazutka et al , 2003). To use plants from natural populations is the best approach to the assessment and prognosis of the state of natural ecosystems.…”

Bioindication-based Estimation of Technogenic Impact on Pinus sylvestris L. Populations in the Vicinity of a Radioactive Waste Storage Facility

The spectrum and frequency of cytogenetic aberrations in the reproductive (seeds) and vegetative (foliage) organs of Scotch pine ( Pinus sylvestris L.) have been studied in the vicinity of the LSK Radon facility for radioactive waste storage and processing and in a 30-km zone around the Chernobyl Nuclear Power Plant.The results indicate that the pine populations of these regions are exposed to mutagenic factors. In contrast to the 30-km Chernobyl zone, the increased environmental mutagenicity in the vicinity of LSK Radon and in the center of the city of Sosnovyi Bor is mainly accounted for by chemical factors. The results of additional acute γ -irradiation have shown an increased radiation resistance of Scotch pine seeds from the LSK Radon and Sosnovyi Bor populations. Regression analysis demonstrated a significant increase in the cytogenetic aberration rate in plants from the experimental plots throughout the study period (1997)(1998)(1999)(2000)(2001)(2002).
