Lithophaga Lithophaga

The edible mussel Lithophaga lithophaga is considered as one of the most important human food sources in Alexandria, Mediterranean Sea. The present study is designed to determine the seasonal bioaccumulation levels of Cd, Co and Pb in the whole soft tissues as well as different tissues of Lithophaga lithophaga. Results revealed that the seasonal bioaccumulation levels of Cd, Co and Pb in date mussel were below the permissible limits or other reported values from other regions of the Mediterranean. On the other hand, the order of metals accumulation level in different tissues was as follows: digestive gland>remaining soft tissues>gonads. The present study confirmed the role of digestive gland as a concentration center for heavy metals. Moreover, total protein content and stress protein responses of the whole soft tissues were evaluated. The total protein content was arranged in the following order: summer>autumn>spring>winter. Five novel stress proteins appeared in summer. The histological and ultrastructural studies of the digestive gland of Lithophaga lithophaga collected in summer and spring showed marked histopathological alternations.

Biomarkers Of Effect

Background. Inhalation of thermal water has been used empirically in the treatment of chronic diseases of upper and lower respiratory tract. This study investigates biomarkers of effect in exhaled breath (nitric oxide (NO)) and in exhaled breath condensate (EBC) (hydrogen peroxide (H2O2), anions, toxic heavy metals of tobacco smoke) for patients with lung diseases inhaling salt-bromide-iodine thermal water. Methods. This study enrolled two groups of patients, twenty with alveolar pulmonary diseases—pneumoconiosis—twenty-two with bronchial diseases. Patients received 12 days inhalation treatment with thermal water in Terme of Monticelli (Parma), Italy. Results. No statistically significant differences were found for NO at different flow rates in both groups of patients before and after thermal water inhalation. Also in EBC no statistically significant differences were present for H2O2 concentrations, toxic heavy metals concentrations, and anion concentrations before and after treatment. Nitrates in EBC were found to be significantly higher in patients before inhalation than in controls as well as in patients after inhalation versus controls. Conclusions. This study contributes to better quantify functional and biochemical changes in airways before and after thermal water treatment.

Heavy metal pollution was reported in commercially valuable and edible pigeon (Columba livia, Gmelin 1789) of Bangladesh. The concentrations of As, Pb, Cd, Cr, Zn, and Cu were investigated in the muscle, intestine, kidney, gizzard and liver. For this 60 C. livia were selected from five locations to assess the degree of pollution by heavy metals in pigeon. Significant differences in heavy metal concentrations were observed among different tissues, but not among the locations. The ranges of the measured concentrations (?g/g dry weight) in the tissues of C. livia were as follows: arsenic: (0.01–0.04), (0.02–0.04), (0.02–0.08), (0.02–0.04) and (0.03–0.07); lead: (0.21–0.56), (0.07–1.64), (0.62–1.97), (0.41–0.79) and (1.47–5.75); cadmium: (0.01–-0.05), (0.13–0.97), (0.53–1.85), (0.32– 0.78) and (0.22–2.41); chromium: (0.25–1.93), (1.18–5.90), (1.59–4.40), (1.15–1.65) and (1.38–8.36); zinc: (73.22–256.56), (95.62–130.75), (19.87–67.18), (108.99–124.77) and (159.80–280.76); copper: (3.44–7.64), (5.30–17.50), (8.72–16.55), (1.19–34.42) and (26.09–43.60) in the muscle, intestine, kidney, gizzard, and liver, respectively. This research showed that the liver appeared to be the main storage site of heavy metals, while the muscle had the lowest levels of the analyzed metals. The concentrations of metal in the muscles were not found to exceed the acceptable level for human consumption.

In this study, Nickel (Ni), Lead (Pb), Cadmium (Cd) and Chromium (Cr) concentrations were determined in muscle, liver, kidney, gills and gonads of Indian mackerel (Rastrelliger kanagurta) collected from Karachi fish Harbour, Karachi coast, Pakistan, during August 2006 and December 2011. Generally, the fish showed the highest level of Ni (2.26+0.89 µg g-1), Pb (1.45+0.40 µg g-1), Cd (2.07+0.75 µg g-1) and Cr (1.52+0.69 µg g-1) in the liver. The studied metals were the most abundant in the liver than the other organs of the fish. The amount of metal accumulation in fish tissues was evaluated in terms of human health. It was seen that bioaccumulations in muscle tissues of the fish caught from Karachi coast of Pakistan did not exceed the limit values.
