“…Micronuclei frequency also decreases in the interphase cell in the next cell cycle [36]. The micronucleus (MN) test, A. cepa and V. faba chromosome aberration test, and the T. MN tests have been recommended as the validated plant bioassays for laboratory testing and in situ monitoring of the genotoxicity of environmental mutagens [7]. Sister chromatid exchange (SCE) test can also be used to detect efects of small doses of pollutants; thus, it is adequate for initial genotoxicity evaluation tests [37].…”

“…Hence, plant bioassays are commonly used for screening and monitoring environmental chemicals with mutagenic and carcinogenic potential [5,6]. The International Program on Chemical Safety (IPCS) makes and supports research programs all around the world and develops methodologies for chemical exposure [4,7]. Many laboratories from diverse regions of the world have been sponsored by IPCS and participated in evaluating the utility of several plant bioassays for detecting the mutagenicity of environmental chemicals [8].…”

Plants are present in almost all areas of the world and can accumulate many chemical compounds present in the soil, water, and atmosphere. As these chemicals which are potentially mutagenic or carcinogenic are absorbed by the plants sharing the same environment with us, bioassays on plants can be used to detect the presence of environmental hazards. Another reason for selecting plants for assessing adverse efects of these chemicals is the ease of experimentation with plants. Evaluating the efect of a substance on basic plant characteristics such as growth, survival, or reproduction is straightforward and repeatable. Thus, various plant species are commonly utilized as indicators of adverse environmental conditions. This chapter covers the detection of environmental mutagens through plant bioassays, considering the increasing importance of biomonitoring using plants for assessing the mutagenicity of relevant chemicals and industrial waste. From this point of view, a detailed literature search was made on the subject. The genotoxic, cytotoxic, and molecular studies have been investigated and the most useful and important parts and key points of these methods were summarized. This review would be useful for scientists who are planning to conduct research on plant bioassays with diferent types of methods and chemicals.

“…Empowered institutions need to be involved with the development of the decision-support subsystem and play a crucial role in assigning responsibilities in management schemes. The interactions between experts and lay people, mediated through social workers (Figure 2), will benefit the development of improved management procedures whose effects can be monitored (Gopalan, 1999). …”

A concept of an ecosystem approach to human health improvement in Sub-Saharan Africa is presented here. Three factors mainly affect the physical condition of the human body: the abiotic environment, vector-transmitted diseases, and natural resources. Our concept relies on ecological principles embedded in a social context and identifies three sets of subsystems for study and management: human disease subsystems, natural resource subsystems, and decision-support subsystems. To control human diseases and to secure food from resource subsystems including livestock or crops, integrated preventive approaches are preferred over exclusively curative and sectorial approaches. Environmental sustainability - the basis for managing matter and water flows - contributes to a healthy human environment and constitutes the basis for social sustainability. For planning and implementation of the human health improvement scheme, participatory decision-support subsystems adapted to the local conditions need to be designed through institutional arrangements. The applicability of this scheme is demonstrated in urban and rural Ethiopia.

“…Among the bioassays developed for detection of mutagenicity, genotoxicity, cytotoxicity and clastogenicity due to environmental pollutants, plant systems have proven to be sensitive, cheap, and effective (Gopalan, 1999;Cabrera and Rodriguez, 1999a,b;Cabrera et al, 1999;Grant, 1999;Ma, 1999;Majer et al, 2005). Plant bioassays, which are mostly sensitive for the detection of genotoxicity, may provide a warning of environmental hazards in the water (Gopalan, 1999).…”

“…Plant bioassays, which are mostly sensitive for the detection of genotoxicity, may provide a warning of environmental hazards in the water (Gopalan, 1999). Plant roots are generally useful tools in biological tests, because they are the first structures to be exposed to chemical variations in the water and soil (Fiskesjö, 1988).…”

Evaluation of the cytotoxic and genotoxic potential of water from the River Paraíba do Sul, in Brazil, with the Allium cepa L. test

This work investigated the cytotoxic and genotoxic potential of water from the River Paraíba do Sul (Brazil) using Allium cepa roots. An anatomo-morphological parameter (root length), mitotic indices, and frequency of micronuclei were analysed. Eight bulbs were chosen at random for treatment for 24 to 120 hours with the River water collected in the years of 2005 and 2006 from sites in the cities of Tremembé and Aparecida (São Paulo state, Brazil). Daily measurements of the length of the roots grown from each bulb were carried out throughout the experiment. Mitotic index (MI) and frequency of micronuclei (MN) were determined for 2000 cells per root, using 3-5 root tips from other bulbs (7-10). Only in the roots treated with samples of the River water collected in 2005 in Tremembé city was there a decrease in the root length growth compared to the respective control. However, a reduction in MI values was verified for both sites analysed for that year. Considering the data involving root length growth and especially MI values, a cytotoxic potential is suggested for the water of the River Paraíba do Sul at Tremembé and Aparecida, in the year of 2005. On the other hand, since in this year the MN frequency was not affected with the river water treatments, genotoxicity is not assumed for the river water sampled at the aforementioned places.
