The present study was included to estimate the Concentration and distribution of selected Heavy elements Cadmium, Lead, Nickel and Zinc from water, sediment and two species of plant ( Phragmites australis and Ceratophyllim demersum). Also same physical characteristic of this river in water , samples were collected of three stations in Al-Gharraf River in order to investigates the possibility of pollution in this area with these elements .three station (Al-Fajr districts , Qal'at Sukkar districts and Al-Rifa'I districts) were chosen to execute this study during the period from May 2018 until February 2019. And the high temperature was recorded (13 ٥C in winter to 30 ٥C in summer), pH (7.44 to 7.8) and Turbidity (2.41 to 10.2)NTU. and salinity (0.01 to 0.069) ppt. Also all the heavy metals recorded a significant increase in water and Ceratophyllin demersum plant samples in the winter higher than summer and in the sediments and Phragmites australis plant the rise in the winter was only in the elements nickel and zinc, but in cadmium and lead were concentration low or do not make a big difference in the winter compared to the summer , Where the highest percentage of nickel and zinc in the sediments in the second and third stations respectively reached 86.2 mg / kg dry weight . The lowest concentration of cadmium concentration in water samples at the first station for the summer was 0.0021 mg / L . Where there is a positive relationship between the increase in concentrations of heavy metals in the samples studied and increase in the amount of rain , speed of runoff and the rise in water level in the river in winter due to the volume of rising smoke as a result of pollution which descends during the rainfall and erosion of the edges of the river and lack of control over the domestic sewage that has been brought into the river . As well as probable cause to exist Al-Gharraf oil field that newly established and located north of Fajr city, was considered a control station and opposite to the Qal'at Sukkar city and south of Al-Rifai city we can be observed through the results which show a gradual rise in the second and third stations and third station was higher than stations 1 and 2.

Cadmium (Cd) and lead (Pb) are known to have high toxic effects and have been found polluting marine environment. Regular monitor the concentration of heavy metals in marine waters is necessary by combining chemical and biological analysis. This research was conducted to analyze the levels of heavy metals in sediment, water column, cardinal fish Apogon beauforti, and to measure the concentration of MTF-1 protein in A. beauforti. This research was conducted at four sampling stations at Ambon bay for 2 years. The levels of Cd and Pb metals were analyzed using AAS instruments (Atomic Absorbsion Spectrophotometer), while the concentration of MTF-1 protein in the body of A. beauforti was analyzed using indirect ELISA. The results showed that the seasonal and spatial distribution of heavy metals Cd and Pb at Ambon bay did not show any variation. The results of the ANOVA proved that the concentrations of heavy metals Cd and Pb in the four research stations were not significantly different in the year 2013 and in the year 2014 in the samples of sediment, the water column, and the body of A. beauforti. In addition, it was revealed that the concentration of MTF-1 protein of A. beauforti in 2014 was higher than that in 2013, with an average of the concentration of MTF-1 protein of A.beauforti was higher at station 2, which was at Ferry Galala Harbor.

The article focuses on the study of change of containing heavy metals (zinc, copper, iron, cadmium, lead, arsenic) in the abiotic and biotic components of the Serepok river (Vietman) influenced by wastewater discharge from industrial areas. Heavy metal content was determined in the river water and bottom sediments in the four zones: above and within the boundaries of industrial regions Xoa Phu and Tam Thang and in two water reservoirs situated below the boundaries of those industrial areas. Tilapia Galilean ( Sarotherodon galilaeus ), Hemibagrus ( Hemibagrus ), and sazan ( Cyprinus carpio ) caught in these areas were the hydrobionts under study in which liver, gills, skeleton and muscles accumulation of heavy metals was detected. In the organs of fish caught in the river within industrial region, heavy metals concentration was 3-7 times higher. The greatest concentration of heavy metals was found in the liver and gills of fish caught in the boundaries of industrial regions, the least concentration was in the muscles. In most cases, significant correlation between heavy metal concentration in organs of fishes and in river water, bottom sediments has been revealed.

AbstractChemical contamination of foods pose a significant risk to consumers. A source of this risk is due to the consumption of products contaminated with heavy metals such as cadmium (Cd) and lead (Pb). The aim of the study was to research the levels of Cd and Pb contamination of selected species of vegetables and fruits in the form of fresh, frozen, dried and processed products. The goal was to verify which of these food groups was more contaminated with heavy metals. The study covered 370 samples of fruits and vegetables including apples, pears, grapes, raspberries, strawberries, cranberries, as well as beetroots, celeries, carrots and tomatoes. The content of Cd and Pb was determined by atomic absorption spectrometry. Quantitative results were analyzed using statistical models: analysis of variance, outlier analysis, post-hoc multiple comparison Tukey test. The tests showed that the levels of Cd and Pb concentration in samples of fresh, processed, frozen and dried fruits and vegetables varied substantially. The highest concentrations were recorded in dried products. Several fruit and vegetable samples exceeded the maximum permissible concentrations of Cd and Pb. The contamination of these products could be a significant source of consumer exposure to heavy metals when these products are a part of the diet.
