In this study, the genotoxic and cytotoxic potential of lambda-cyhalothrin (LCT), a synthetic pyrethroid insecticide, was investigated in Wistar rat bone-marrow cells, using the structural chromosomal aberration (SCA) and micronucleus (MN) test systems. LCT was administrated to adult female albino rats as repeated i.p. doses of 6.12, 3.06, 0.8 mg/kg BW for 13 days at 48 h intervals. Mitomycin C (MMC) was used as a positive control (2 mg/kg BW). All the doses of LCT increased the number of structural chromosomal aberrations and the frequency of micronucleated erythrocytes, compared with the control group. It was also observed that LCT caused a significant decrease in the number of polychromatic erythrocytes. Our results demonstrate that LCT has a clastogenic/genotoxic potential as measured by the bone marrow SCA and MN tests in Wistar rats.

Domoic acid (DA) is a neurotoxicant produced by Pseudo-nitzschia from diatomeae. Although the neurotoxic and genotoxic effects of DA have been well documented, the number of in vivo studies regarding the oxidative stress inducing effects of DA is quite limited. In this study, in vivo toxic effects of DA were investigated on fish Oreochromis niloticus (Fam: Cichlidae), using oxidative stress biomarkers. Fish were exposed to three different concentrations (1, 5 and 10 microg/g body weight) of DA via intraperitoneal injections and the tissues were sampled at 24, 48 and 72 h post-treatment. Changes in the level of lipid peroxidation, and activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and glutathione reductase (GRd) were evaluated in liver and gill tissues. Our results revealed dose and time dependent increases in the oxidative stress parameters. It was also observed that the toxic effects were more pronounced in liver than in gill tissue.

Textile mill effluent is an important pollution factor because of its organic and inorganic substances content. In this study, toxic effects of textile mill effluent on fish Oreochromis niloticus were investigated by using antioxidant enzymes and lipid peroxidation (LPO) responses. Superoxide dismutase (SOD), catalase (CAT) enzyme activities and lipid peroxidation by means of thiobarbituric reactive substances (TBARS) level were measured in liver and gill tissues of fish. The fish were exposed to non-lethal concentrations (0.1%, 1% and 10%) of textile mill effluent for 15, 30 and 45 days. In control group, fish were left in aquariums containing tap water without chlorine. As a result, the activities of SOD, CAT enzymes and level of TBARS in the liver and gill increased in 15, 30 and 45 days after 1% and 10% doses application.

In this chapter we evaluate the data of 18 Organochlorine pesticides (OCPs) found in breast milk samples from 44 mothers in the Taurus Mountains in Turkey. In this approach the association of concentration levels in breast milk samples with the two confounding factors: smoking habit and habit of taking medication is the goal. For all data evaluation approaches, we applied the Hasse diagram technique and its software package, namely the PyHasse software. Special emphasis was laid on the software features “similarity” and “Local Partial Order Model” to draw further conclusions out of the data. The data analyses resulted in differences between the smoking women and those who did not smoke as well as between the medication and non-medication breast milk samples. Little differences were found comparing hormone taking mothers and mothers taking other medication.
