The Investigation of the Cytotoxic Effects of Some Pesticides on Soybean (&lt;i&gt;Glycine max&lt;/i&gt; L.)

“…Many researchers also found that the diferent kinds of species used do not respond similarly to toxic chemicals [22,23]. Seed germination and plant growth bioassays are the most common techniques used to evaluate the toxicity of pesticides [24][25][26][27], heavy metals [6], allelochemicals [28], personal care products [29], compost [30], water samples taken from rivers [31], and industrial waste waters [25,32]. Diferent plant species have also been used such as cucumber and cress [33], letuce and soybean [34], red maple, sugar maple, white pine, and pink oak [35] for phytotoxicity tests.…”

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.

“…An additional set of caryopses germinated in distilled water with actively growing roots of at least 2.5 cm in length were placed on Petri dishes and exposed to 500, 1000, 2000 mg L -1 nCeO2 suspensions for 24 h. Ten root tips per each treatment, prepared according to Aksoy and Deveci (2012), were studied to evaluate possible genotoxic effects of nCeO2. According to Mattiello et al (2015), each treatment was replicated three times, for a total of about 10,000 cell observations.…”

Engineered nanomaterials and crops: physiology and growth of barley as affected by nanoscale cerium oxide

In recent years, remarkable progress has been made in developing nanotechnology. This has led to a fast-growth of commercial applications, which involve the use of a great variety of manufactured nanomaterials. Given that, soils and sediments are the ultimate sinks of engineered nanomaterials (ENMs), they can be taken up by microorganisms, nematodes, earthworms or plants, and potentially transferred to the food chain up to animals and humans. However, the reactions of the biota exposed to ENMs of different size are still not well understood. Very few studies on nanoparticles-plant interactions have been published, so far. In this paper we report the results of multiple experiments carried out to study the effects of cerium oxide nanoparticles (nCeO2) on Hordeum vulgare. The nCeO2 powder and suspension were characterised for specific surface area, z-average size, and zeta potential. Germinating caryopses and barley seedlings were exposed to an aqueous dispersion of nCeO2 at respectively 0, 500, 1000 and 2000 mg L -1 . Data on root elongation, mitotic index and cerium concentration in seedlings were collected. Plants of barley were grown to physiological maturity in soil enriched with respectively 500 and 1000 mg kg -1 of nCeO2. We reported that seed germination was not affected by the nCeO2, however, signals of genotoxicity were evidenced by mitotic index coupled with a shortage of root elongation. In the life-cycle experiment although no toxicity symptoms were detected, we demonstrated that barley growth was affected by nCeO2.
