The aim of the study To see the effect of location, season and display time on the accumulation of some heavy metals (Lead, copper, zinc, cadmium and cobalt) in sheep and cattle liver. Liver samples were obtained from three districts in Anbar province (Ramadi, Hit and Baghdadi). This study began from January 2017 to November 2017 for all seasons (winter, spring, summer and autumn) Samples were taken from the liver immediately after slaughter for cattle and sheep at 8 am and taken at 4 pm for all areas of study. The results of the study were summarized in the quadratic overlap of the animal type, season, location and time as follows: The highest concentration of lead in liver (38.86 μg / g liver) was recorded in sheep for spring and evening in Ramadi. The lowest concentration was in sheep in Baghdadi for morning and winter (20.06 micro g / g liver). The highest concentration of copper in the liver (34.65 microgram / g liver) was recorded in cows in Ramadi for the winter season and evening time. The lowest concentration was in the sheep liver during the summer season for morning time in the city of al-Baghdadi (20.43 microgram / g liver). The highest concentration was in the liver (603.99 microgram / g liver) in the sheep for the autumn season and the evening time in the city of Ramadi. The lowest concentration was in the sheep in the city of Baghdadi for morning and summer (560.32 microgram / g liver). The highest concentration of cadmium in the liver (30.88 micro g / g liver) was in sheep in Ramadi for the autumn and evening season, and the lowest concentration was in beef in the summer season for morning time in al-Baghdadi city (9.66 μg / g liver). Cobalt was the highest concentration (1.34, 1.34 and 1.35 micro g / g liver) in cow and sheep liver, autumn, summer and evening time for Ramadi. While the lowest concentration of sheep and cattle liver for the city of Baghdadi for the winter season and morning time (0.64 and 0.63 microgram / g liver).

The paper deals with monitoring of pollution arising due to agrochemicals and pesticides manufacturing industries located along the Dombivali industrial belt of Mumbai, India. The study was carried for the period of one year from June, 2012 to May, 2013 to study the level of toxic heavy metals and the physico-chemical properties of waste water effluents discharged from the above industries. The average concentration of Cu, Ni, Cr, Pb and Zn was found to be maximum of 29.86, 0.90, 1.16 and 1.19 ppm respectively in summer season, while average Fe concentration was maximum of 51.10 ppm in winter season. The average pH value of the effluent was found to be maximum of 12.95 in summer season, while average conductivity value was maximum of 21085 µmhos/cm in rainy season. The majority of physco-chemical parameters like alkalinity, hardness, salinity, chloride, cyanide, phosphate, total solid, BOD and COD content were found to be maximum in summer season having the average values of 1918, 186, 4, 11.20, 0.07, 81, 6391, 685 and 2556 ppm respectively. The average DO content was found to be low of 4.5 ppm in winter season. It was observed that the concentration level of majority of the toxic heavy metals and physico-chemical properties were above the tolerable limit set for inland surface water. The results of present study indicates that the existing situation if mishandled can cause irreparable ecological harm in the long term well masked by short term economic prosperity due to extensive industrial growth

Urban roadside dust samples from Dhaka City in Bangladesh were collected from a planned residential area (PRA), spontaneous residential area (SRA), commercial area (CA), and urban green area (UGA) in winter and summer to study how season and different urban land-use categories influence the concentrations of heavy metals (Cr, Mn, Co, Ni, Cu, Zn, As, and Pb) and different pollution indices. The dust samples were fractionated into <32 μm particles, extracted by acid digestion followed by estimation of heavy metals, using ICP-MS. Pollution indices were calculated from the metal concentrations, using standard protocols. The concentrations of heavy metals in roadside dust varied significantly (all p < 0.05), due to sampling seasons and the land-use category. Higher concentrations of heavy metals (Cr, Mn, Ni, Cu, Zn, and Pb) were found in the dust sampled during the winter season than in the summer season, except for As and Co. The geo-accumulation index (Igeo) indicated that the commercial area was heavily contaminated with Cu and Zn during the winter season. The contamination factor (CF) was higher for Cu and Zn in the CA, PRA, and SRA of Dhaka City in winter than in the summer season. The enrichment factor (EF) suggested that Mn and Co were the least enriched metals, and significant enrichment was seen for Cu and Zn for all land-use categories, both in summer and winter. A moderate potential ecological risk for Cu was estimated in CA and PRA in the winter season.

The contamination of aquatic systems with heavy metals is affecting the fish population and hence results in a decline of productivity rate. River Kabul is a transcountry river originating at Paghman province in Afghanistan and inters in Khyber Pakhtunkhwa province of Pakistan and it is the major source of irrigation and more than 54 fish species have been reported in the river. Present study aimed at the estimation of heavy metals load in the fish living in River Kabul. Heavy metals including chromium, nickel, copper, zinc, cadmium, and lead were determined through atomic absorption spectrophotometer after tissue digestion by adopting standard procedures. Concentrations of these metals were recorded in muscles and liver of five native fish species, namely,Wallago attu,Aorichthys seenghala,Cyprinus carpio,Labeo dyocheilus, andOmpok bimaculatus. The concentrations of chromium, nickel, copper, zinc, and lead were higher in both of the tissues, whereas the concentration of cadmium was comparatively low. However, the concentration of metals was exceeding the RDA (Recommended Dietary Allowance of USA) limits. Hence, continuous fish consumption may create health problems for the consumers. The results of the present study are alarming and suggest implementing environmental laws and initiation of a biomonitoring program of the river.

The accumulation of copper, zinc, cadmium, and lead by the marine planktonic diatom D. brightwellii cultured under laboratory conditions is described. With the exception of copper, the concentration of metal taken up by D. brightwellii generally increased with increasing concentration of the metal in the medium. From calculated biological concentration factors (BCF), metal uptake was in the order Zn > Pb > Cu > Cd. For each metal, the BCF value and percentage uptake generally decreased with increasing metal concentration in the medium.

The Sasar River basin covers an area of 311 sq.km and it is situated in NW Romania. The investigated area is included, mainly, in the industrial area of the city of Baia Mare, an ar ea with ancient traditions related to the exploitation of non-ferrous ores. Therefore, the mining exploitation activities have created pressing conditions on the environmental and public health of the analyzed area.The dynamic indicators of water quality on specific toxic pollutants  ( metals )  for the period 19982007 were analyzed in three sections located upstream and downstream from the industrial centers of Baia Sprie and Baia Mare.The analyses of the dynamics of heavy metals in the waters of the Sasar River have found that, the main issues are high Pb and Cu indicators for the upstream section of Baia Sprie; as for the section downstream of Baia Mare, the Zn, Cd and Mn indicators are found in such concentrations that their values determine a high level of toxicity for the monitoring section.There is a clear reduction trend in specific toxic pollutants for the upstream section of Baia Sprie. Special problems continue to be reported for zinc, cadmium, manganese and lead, for the sections downstream of Baia Mare and upstream from the confluence of the Sasar and Firiza Rivers.

Abstract The aim of the research was to assess the level of contamination with heavy metals (manganese, iron, nickel, copper, zinc, cadmium and lead) in two forest areas selected in different places in Poland: the first one in the Swietokrzyskie Province (forests of the Staporkow Forest Division) and the second one in the Opolskie Province (forests of the Kup Forest Division). The degree of contamination of these forest areas with analytes was found using edible large-fruited mushrooms naturally occurring there - the research was carried out using passive biomonitoring method. Heavy metals in mushrooms (separately in stems and hats) as well as in soil samples were determined by atomic absorption spectrometry with excitation in flame (F-AAS). The obtained results were interpreted by assessing the degree of contamination of forest areas on the basis of concentrations of heavy metals in mushrooms. The obtained results indicate an increased accumulation of heavy metals in hats than in mushrooms stems. On the basis of the obtained data, significant contamination of forest areas with selected heavy metals was also found. This is confirmed by the possibility of using mushrooms as biomonitors in passive biomonitoring of forest areas, which are heavy metal accumulators. In the interpretation of the test results, the phytocumuling factor (PF) was also used. The degree of accumulation of heavy metals, from given forest areas - from soil to mushrooms - was assessed on the basis of determined PF coefficients. In addition, good bioavailability of the analysed analytes by mushrooms was found. Additionally, on the basis of the conducted studies, the possibility of mushroom consumption was assessed - they are not suitable for consumption due to the fact that the permissible concentration standards of heavy metals contained in mushrooms were exceeded.

The paper reveals the content of extractable zinc, cadmium and lead in the soil of the territories with different level of technological influence. The peculiarities of heavy metals storage by dooryard plantains leaves Plantago major L. are observed. The soils of the industrial zone are characterized by pollution with cadmium and lead compounds. The content of lead and zinc ions in dooryard plantains leaves P. major , growing in this region, oversteps the accepted values. The plant material picked in the suburbs of the city close to the forest zones is ecologically safe. According to increasing of accumulation features, heavy metals are located in the following order: lead cadmium zinc that reflects the degree of their importance for plants and the similarity of their physical and chemical indexes. The higher indexes of the storage coefficients for cadmium in comparison with lead are connected with its translocation into cells by carriers for zinc biophile element. The increase of zinc and cadmium content in the soil leads to decrease of accumulation of these ions in leaves. Lead gets into dooryard plantains leaves P. major from both through roots from the soil and through mouth apparatus of leaf epidermis from the air.

The tentative permissible concentrations and the maximum permissible concentration of heavy metals do not always give a complete adequate assessment of the effect on plants. Plant growth inhibition can be at concentrations below the maximum permissible concentrations and tentative permissible concentrations. We studied the effect of copper, zinc, cadmium, and lead concentrations on plants. The object of the research is the lawn grass, the Agrostis stolonifera used in urban greening. According to the data obtained, Agrostis stolonifera showed a low degree of resistance to copper, lower than the tentative permissible concentration and the maximum permissible concentration. Consequently, the tentative permissible concentration and the maximum permissible concentration do not fully reflect the real phytotoxicity of copper. Plants of Agrostis stolonifera demonstrated a relatively high sensitivity to zinc in comparison with the maximum permissible concentration and the tentative permissible concentration. The content of cadmium and lead corresponding to the tentative permissible concentrations did not have a significant effect on the plants.

The aim of the present study is to investigate the bioaccumulation and translocation of various heavy metals, notably copper, zinc, cadmium and lead, in the different plant organs of Trapa natans L. (the root, stem, and leaf) at nine sampling locations, as well as examining the variability in proline accumulation and chlorophyll content due to these heavy metals. Our analysis shows the existence of a statistically significant positive correlation (r = 0.75; p < 0.05) between the Zn content and the accumulation of proline in the root of the examined species. On the other hand, a statistically significant negative correlation was registered between the content of chlorophyll a and the concentration of Zn in the leaf (r = −0.68; p < 0.05). This indicates that Trapa natans L. can be used in biomonitoring Zn-polluted aquatic ecosystems using proline and chlorophyll as sensitive biomarkers.
