“…The phytotoxicity of different soluble textile dyes was estimated by measuring the relative changes of the aforementioned plant parameters using clover, wheat, tomato and lettuce as test plants. Similar study was conducted by REN et al (1996) who demonstrated the toxicity of polycyclic aromatic hydrocarbons (PAHs), anthracene (ANT), benzo[a]pyrene (BAP), and fluoranthene to the duckweed Lemna gibba L. and Brassica napus L. (oil seed rape) seeds. These authors used the germination efficiency, root and shoot growth, and chlorophyll content, as a measurement for toxicity.…”

The toxicity of eight textile dyes was evaluated using two bioassays namely: Ames test and seed germination test. The Ames test is widely used for the evaluation of hazardous mutagenic effect of different chemicals, as a short-term screening test for environmental impact assessment. The eight-textile dyes and Eithidium bromide dye (as positive control) were tested with five "his" Salmonella typhimurium strains: TA 100; TA 98; TA 1535; TA 1537; TA 1538. Using six concentrations of each dye (2.5 microg/ml, 4.5 microg/ml, 9 microg/ml, 13.5 microg/ml, 18 microg/ml, and 22.5 microg/ml) revealed that, most of the dyes were mutagenic for the test strains used in this study. The high concentrations of dye eliminated microbial colonies due to the high frequency of mutation causing lethal effect on the cells. In this work the phytotoxicity of different soluble textile dyes was estimated by measuring the relative changes in seed germination of four plants: clover, wheat, tomato and lettuce. The changes in shooting percentages and root length as affected by dye were also measured. Seed germination percent and shoot growth as well as root length were recorded after 6 days of exposure to different concentrations of textile dyes in irrigation water. The results show that high concentrations of dyes were more toxic to seed germination as compared with the lower concentrations. However, the low concentrations of the tested dyes adversely affected the shooting percent significantly.

Mechanical and Leaching Behavior of a Stabilized and Solidified Anthracene-Contaminated Soil

This paper presents an investigation into remediation of an anthracene-contaminated clay soil through experimental tests. Samples were prepared of uncontaminated and contaminated soil-cement with 20 and 30% cement. Unconfined compression tests (UCT) were conducted on the natural soil and soil contaminated with anthracene. In addition, similar tests were carried out on uncontaminated and contaminated soil-cement at different curing times. Leaching tests were also conducted on contaminated soil and

“…Phthalates hinder morphometric parameters, increase malondialdehyde (MDA) levels, and decrease pigment amounts in higher plants. PAHs impair photosynthetic efficiency in lichens, probably due to phosphorylation of the antenna complex and subsequent detachment from photosystem II (Kummerova et al, 2005), or they can depress plant root fresh weight after photoactivation (Ren et al, 1996). Manganese promotes chlorophyll degradation in epiphytic lichens (Hauck et al, 2003), nickel increases the susceptibility to atmospheric pollution of species like Usnea amblyoclada (Müll.…”
