Model Subject

The chronic ecotoxicological effects of Cd, Cu, Pb, Se and Zn were determined within this study. Mustard seedlings (Sinapis alba L.) were used as a model subject for the tests. The phytotoxicity was determined through the root growth inhibition and photosynthetic pigments production (chlorophyll a, b, total carotenoids). The metal accumulation in the roots and cotyledons was also determined using the AAS methods. On the basis of IC<sub>50</sub> values and their 95% confidence intervals (CI) for the root elongation of S. alba seedlings, metals can be arranged in the rank order of inhibition as follows: Cu &gt; Se &gt; Cd &gt; Zn &gt;&gt; Pb. When the photosynthetic pigments production was determined, Se demonstrated the lowest inhibitory effect on all pigment types and Pb did the highest. The accumulated amount of metals from hydroponic solution into the roots and cotyledons decreased in the order Cd &gt; Zn &gt; Se &gt; Pb &gt; Cu.

Introduction: The constant impact on the environment occasioned by pollution, indiscriminate application of agricultural chemicals, security challenges and crisis in the Niger Delta ecological area of Nigeria has caused severe damage to plants, soil organisms and humans. Aim and Methodology: In this research, onions (Allium cepa L) was exposed to varying concentrations of an atrazine-based selective herbicide Arda-force® to estimate the phyto-toxic effects on the plant species using the Organization for Economic Co-operation and Development, (OECD) protocol #208. Results: The mean effective concentration (EC50) using root growth inhibition produced indications of phyto-toxicity to the exposed species at a concentration of 0.55 ± 0.06 mg/L. Similarly, the maximum root growth inhibition efficiency relative to the control was 65% as recorded in the highest test concentration of 1.25 mg/L. Discussion: The study indicated that constant application / indiscriminate use of the herbicide Arda-force® could cause deleterious influence on these plant and vegetable species, daily consumed by humans as a rich source of anti-oxidants. Conclusion: This study concluded that atrazine-based herbicide Arda-force® used in this assessment resulted in phyto-toxic effects to Allium cepa L. At the exposed concentrations of the herbicide to non-target specie – Allium cepa L. that are integral parts of the ecosystems, the ‘‘harmless’’ status of atrazine acclaimed by the United State Environmental Protection Agency (USEPA) is still very much in doubt.
