Opis:
Until recently, the level of industrial air pollution in the Sudetes (a mountain range extending on the Czech Republic and Poland border) was very high.This caused a large-scale forest decline, especially in the western part of the Polish Sudetes: in the Izerskie and Karkonosze Mts. An analysis of data on fir defoliation in that area, collected directly after the period of heavy industrial pollution, showed a clear dependence of the degree of defoliation of the primary crown on canopy density: the lower the density, the higher the degree of defoliation.

Opis:
The Dombivli city near Mumbai has rapid industrialized. However the improper environmental planning has resulted in discharge of industrial waste effluents from the industrial belt into the Ulhas River. These wastes from these industries include various toxic heavy metals which subsequently accumulate in the sediments of Ulhas River. This day by day increasing tremendous pollution load has provoked us to carry the systematic and detailed study of heavy metal content in the sediment samples collected along the Ulhas River along the Dombivli City, near Mumbai. The study was conducted in year 2012 and 2013. The study was carried out in along the banks of Ulhas River near the discharge of effluents from Dombivli Industrial belt Phase I and Phase II. Accordingly the sampling points were identified. The analysis for the majority of the toxic heavy metals like Cadmium (Cd), Copper (Cu), Nickel (Ni), Chromium (Cr), Cobalt (Co), Iron (Fe), Lead (Pb), Mercury (Hg), Arsenic (As) and Zinc (Zn), in sediment samples was done. From the results of our study, it can be concluded that there is a need of systematic and regular monitoring of pollution level along the Ulhas River so as to generate the data on accumulation of heavy metals in the river sediments which will further help in improving the industrial waste treatment technology adopted along the Dombivali industrial belt. It is expected that such scientific studies will help to gauge the extent of pollution in order to avoid long term irreparable damage to the ecosystem.

Opis:
The aim of this study was to examine Scots pine (Pinus sylvestris L.) xylem changes caused by heavy metal pollution. Annual rings width, number of tracheids in radial rows and the length of tracheids in the wood from trees growing on post‑flotation tailings have been measured. Dimensions of tracheids have been examined separately for earlyand latewood of each radial increment. The most demonstrable changes are observed in the tracheids length, which appears to be shorter in the xylem from the industrial area than in the control samples. In the wood from the polluted site, the variability of length of tracheids is increased. Microscopic observations revealed numerous deformations in the xylem tissue and deviations from the standard cell arrangement. Circumferential deformations occurring in the wood structure may indicate the increasing spring frost vulnerability of these trees.

Opis:
The paper deals with monitoring of pollution arising due to textile based 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 concentration level of majority of toxic heavy metals like Cu, Ni, Pb, and Zn were reported to be maximum of 45.58, 2.00, 2.06 and 9.20 ppm respectively in the month of April, while Cr and Fe concentration levels were found to be 2.50 and 55.30 ppm in the month of March. The effluent samples collected in the month of July was reported to show high BOD content of 564 ppm, while COD content was maximum of 2436 ppm in the month of October. The effluent samples collected in the month of January was having very low DO content of 3.21 ppm and high cyanide content of 0.09 ppm. The alkalinity, hardness and chloride content were maximum of 2158, 198 and 2765 ppm respectively in the effluent samples collected in the month of February. The effluents were having high total solid content of 8269 ppm during the month of April, while the salinity and phosphate contents were reported high of 5.64 and 125.70 ppm during the month of May. It was observed that the concentration level of majority of toxic heavy metals and the values of various physico-chemical parameters were above the tolerable limit set for inland surface water. The present experimental data on environmental risk assessment studies due to textile industries may be regarded as an aid towards a better understanding of the problem arising due to such industries. There is a need to convey the message that prevention of adverse health effects and promotion of health are profitable investments for employers and employees as a support to a sustainable development of economics.

Opis:
The leaf blades of white ash Fraxinus americana L. and London plane tree Platanus acerifolia Willd. growing in heavy polluted industrial areas were studied for morphological and anatomical changes developed under the influence of industrial contamination. The aim of the investigation was to determine and compare the influences of air polluted with SO2, NxOx, Pb, As, Zn, Cu etc. on the morphology and the structure of the leaves of these deciduous trees. Both species are tolerant to environmental changes but with different environmental characteristics and tolerances and they are widely used for planting. Under polluted conditions, the trees strengthened the anatomic xeromorphic characteristics of their leaf structures, which gave them the opportunity to mitigate the stressful conditions of the environment. The observed responses are regarded as adaptive and compensative to the adverse effects of air pollution.

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 concentration level of majority of toxic heavy metals like Cu, Cr, Pb, Fe and Zn were found to be maximum of 14.06, 0.57, 0.42, 18.93 and 3.31 ppm respectively in the month of February, while Ni concentration was found to be maximum of 0.43 ppm in the month of June. The pH and BOD values were reported to be maximum of 12.54 and 546 ppm respectively in the month of October. The conductivity and total solid content was found to be maximum of 27400 μmhos/cm and 9401 ppm respectively in the month of June. The cyanide content was maximum of 0.13 ppm in the month of April. The alkalinity, hardness, salinity, chloride, phosphate and COD content was reported maximum of 852, 694, 10.36, 4821, 46.32 and 1271 ppm respectively in the month of February. The DO content was found to be minimum of 3.00 ppm in the month of February. It was observed that the level of many of these toxic heavy metals except Zn and various physico-chemical parameters were above the tolerable limit set for inland surface water. From the results of the present investigation it seems that the time has come to move towards ecosystem specific discharge standards to maintain the health and productivity of natural resources on which the majority of Indians are dependent.

Opis:
Toxic pollutants of industrial origin can be dangerous for professionals who come into contact with them at work, and also for the people who live near the sources of environmental hazards. There is a known relationship between the soil pollution with heavy metals and the morbidity of the population. This paper reports a study of the soil pollution with ions of heavy metals in the Turkestan region, Kazakhstan. The study found technogenic geochemical anomalies of various size, intensity and origin in the soils of the Turkestan region. The distribution of lead, copper, barium, zinc, molybdenum, phosphorus and arsenic was mapped based on the ecological and geochemical survey of the upper soil layer. The most polluted city is Kentau, where concentrations of Pb, Mo, Cu, Zn, As, Cd, Mn, Cr, Ni in the soil exceed the allowable level. The cause of pollution is erosion that occurs in the areas of technogenic waste storage. In some communities, the concentration of only one metal exceeded its MAC or the Clarke number, for example, only scandium exceeded its Clarke number by 1.1 in Lenger and only exceeded its Clarke number by 2.75 in Sholakkorgan.

Opis:
This paper focused on the fate of pollution and management of hexavalent chromium Cr(VI) and heavy metals in the Zarqa River Basin in Jordan. The Zarqa River basin was selected in this research because it contains the majority of Jordanian industries, which are the main source of pollutants including Cr(VI) and heavy metals. This will help in assisting water resource management organizations in decision making when coping with pollution. Industries related to sources and impacts of Cr(VI) and heavy metals were identified, and the administration measures were highlighted according to their role in improving water quality. An analysis of water samples along the Zarqa River was conducted between 2016-2019 to evaluate the heavy metals concentrations and compare the results with the Jordanian standards. Findings showed that Cr(VI) was below the allowable limits (<5 μg/l), and the heavy metals were within the allowed limits set forth in the Jordanian Standard. The ranges of water analysis values (μg/L) were; DO 4640–6480, Fe <40–80, Mn 20–128, Co <20–30, Pb 80–190, Zn 70–100, and Cu <80–190, Al 700–730, V <70–100, B <300–351, Si 1100–1800, Ni 30, and Cd <10. These findings indicated that the quality of the Zarqa River would not cause hazardous effects. However, this was not the case few years ago due the current protection measures. At present some industries have been relocated from the Zarqa Basin to an area that does not pose any environmental hazards, while the rest of industries remained in the basin, but they have established an on-site treatment plant for industrial waste under the control of Jordanian government, and the enforcement of the environmental protection law. These measures must be monitored and updated by decision makers in a sustainable manner to prevent any water pollution.

Opis:
This work was undertaken to determine lipids changes in needles of Scots pine (Pinus sylvestris L.) populations growning on polluted stands near a phosphate fertilizer factory in Luboń, and copper smelter in Głogów and in a control area in Kórnik. Needles from polluted areas had a lower content of total phospholipids than samples from the unpolluted site. Greater changes were detected in membranes of needles collected in October and January. In comparison with the control total phospholipid in needles of populations from polluted areas were 14 to 33% lower. Phosphatidylcholine (PC) phosphatidylethanolamine (PE) and phosphatidylglicerol (PG) were the dominant phospholipids. The analysis of fatty acids in phospholipid fraction showed a decrease of linoleic acid (18:2) and linolenic acid (18:3) contents. The level of polyunsaturated fatty acids in needles of three populations from polluted areas was up to 40% lower as compared with the control. Moreover, phospholipids and their fatty acids showed seasonal fluctuations. The contents of PC, PG and PE increased in autumn and in winter, during the process of cold acclimation. In July, current-year needles did not show significant differences in membrane lipid composition between the polluted areas of Scots pine populations. The results suggest that the lipid changes of needles could be associated with disturbances in phohospholipid metabolism, caused by environmental pollution.
