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.

AbstractA national-scale study in Italy showed an incidence of cancer higher in the territories indicated as highly polluted compared to the regional average. One of them, the city of Taranto in Apulia (Italy), which is considered one of the most polluted cities in Europe, has numerous industrial activities that impact population health. We studied the epidemiological effects of a high level of pollution produced by the industrial area of Taranto in increasing the mortality rate for some specific cancer types in the city and towns of the two provinces located downwind. We analysed 10-year mortality rates for 14 major types of tumours reported among the residents of Taranto, of 6 surrounding towns, randomly placed within an imaginary cone in the main wind direction from the vertex of the industrial zone of Taranto. Our results confirm our hypothesis that the mortality rate for some specific types of cancer (namely, Hodgkin and non-Hodgkin lymphomas, leukaemia, liver and bladder tumours) are higher than the norm in the municipality of Taranto and we have evidence that other local causes may be implicated in the excess of mortality besides the potential dispersal of pollutants from the industrial area of Taranto. The proximity to the industrial area of Taranto cannot, therefore, explain alone the anomalies detected in some populations. It is likely that other site-specific sources of heavy pollution are playing a role in worsening the death toll of these towns and this must be taken into serious consideration by environmental policy-makers and local authorities.

Abstract The study is focused on environmental assessments of impacts by former briquette factory at the Nagymányok area in South Hungary. The (former) industrial zone is located in a northern valley of the Eastern Mecsek Mountains. Until the 1990s this company was the largest briquette factory in Hungary and the demolition works are still incomplete. former investigations were based on only five samples. our sampling sites were selected on the basis of the source of the contaminations and then we covered the whole area in equal distribution. We used the A1-F6 codes for the sample places. We have started from southwest to northeast. The samples were analyzed for Total Petrol Hydrocarbons (TPHs), Polycyclic Aromatic Hydrocarbons (PAHs) and for heavy metals. The area was heavily contaminated by TPHs and moderately heavy metals (such as Cu, Cr, Zn and Pb). Highest contaminant concentrations were found around the former industrial buildings, especially between the boiler-house and the coal-pillbox. In the industrial area the mean of the detected values is below the upper limit of the legal exposure values, but among the former industrial buildings higher (e.g. toxic level) concentration values were detected in multiple samples. Based on our investigation the pollutant can be transported by wind or by water on the surface (stream bed) or underground. The hazardous material can easily reach some part of the city, therefore reclamation is necesarry.

This research aims to find out the way or role of the Cilegon city environmental service in environmental control caused by industrial waste. To study this theme, this study uses two theories, environmental monitoring and pollution. Cilegon is one of the cities that has a high level of pollution. This happens a lot in the city of Cilegon especially in areas close to industrial areas such as Samangraya, Citangkil District, Kampung Cilodan Gunung Sugih, Ciwandan District, South Ring Road Crossing (JLS). The effect of industrial waste has an impact on the health of residents around the industrial area directly affected by the waste. From data obtained by the Cilegon City Health Office in 2018, there were 21,745 people with non-pneumonic cough and 661 pneumonia sufferers. This makes the city government of Cilegon must increase its supervision of environmental pollution caused by the Cilegon city industry.Penelitian kali ini bertujuan untuk mengetahui cara atau peran dari dinas lingkungan hidup kota cilegon dalam pengawasan lingkungan yang di sebabkan oleh limbah industry. Untuk mengkaji tema ini, penelitian kali ini menggunakan dua teori yaitu pengawasan dan pencemaran lingkungan. Cilegon menjadi salah satu kota yang mempunyai tingkat pencemaran yang cukup tinggi. Hal ini banyak terjadi di Kota Cilegon terutama di daerah yang dekat dengan wilayah industry seperti Samangraya, Kecamatan Citangkil, Kampung Cilodan Gunung Sugih, Kecamatan Ciwandan, Persimpangan Jalan Lingkar Selatan (JLS). Pengaruh limbah industri ini berdampak terhadap kesehatan warga sekitar daerah industri yang secara langsung terkena limbah tersebut. Dari data yang diperoleh dinas kesehatan Kota Cilegon tahun 2018 lalu, tercatat ada sekitar 21.745 pengidap batuk non pneumoni dan 661 penderita pneumoni. Hal ini membuat pemkot cilegon harus meningkatkan pengawasan terhadap pencemaran lingkungan yang di sebabkan industry  kota cilegon.

Este trabalho teve como objetivo, a investigação das concentrações de metais pesados selecionadosem sedimentos de fundo em riachos do Parque Estadual Itacolomi e arredores na região de Ouro Preto,Minas Gerais. A água destes riachos é largamente utilizada pela população ribeirinha, levando estaspessoas a uma situação de vulnerabilidade a qualquer alteração da água. Foram investigados os elementosCd, Cr, Cu, Ni, Pb e Zn. As amostras foram coletadas seguindo a metodologia proposta pela CETESB(1988) e analisadas em um aparelho de espectrometria de emissão atômica do Laboratório deGeoquímica Ambiental do Departamento de Geologia da Universidade Federal de Ouro Preto, M.G.Os resultados mostram que os principais carreadores dos elementos traços nos sedimentos são materialorgânico, minerais argilosos e oxidos e hidroxidos de Al, Fe e Mn. Para se avaliar a existência devalores anômalos de metais traços no sedimento de corrente na área, recorreu-se ao método docálculo do fator de contaminação (F.C.) de cada elemento analisado. Os resultados demonstram que ocádmio tem concentração alta em alguns pontos da área de estudo, caracterizando alguns locais comconcentrações anômalas deste elemento, não podendo se afirmar que se trata de intervenção antrópica.Os outros metais apresentam baixo fator de contaminação, caracterizando a área em estudo comonão anômala para estes metais e suas principais fontes, são as rochas quartzíticas da FormaçãoCercadinho e do Grupo Itacolomi e dos xistos do Grupo Sabará.AbstractThe aim of this work was to investigate the concentration of selected heavy metals in sediments ofthe bottom of rivers in Itacolomi State Park and surroundings, near the city of Ouro Preto, MinasGerais. The water of these rivers and streams is widely used by riverside populations, which let thesepeople vulnerable to water quality alterations. The water of these rivers is important for the provisioningof the population and therefore sensitive to any contamination. The elements Cd, Cr, As, Ni, Pb andZn were investigated. The samples were collected following international standard procedures andanalyses were done by optical atomic emission spectroscopy in the Laboratório Geoquímica Ambiental/Universidade Federal de Ouro Preto, Minas Gerais. The results show that the main carriers of theelements in the sediments are organic material, clay minerals and oxides and hydroxides of Al, Fe andMn.To evaluate abnormal values of trace metals in current water sediments on the area, we used thecalculus of contamination factor method for each element studied. Results show that Cd has highconcentrations in some points of the studied area, characterizing some places with abnormalconcentrations of this element, but it can not be assured that this is caused by antropic action. Othermetals shows low contamination factor, characterizing the studied area as not abnormal for thesemetals, and their main sources are quartzical rocks of Cercadinho formation, Itacolomi Group, andGroup Sabará schists.

The article presents the results of the research work on the peculiarities of recultivation of the ash dumps of power station No1 (PS1) in the city of Khabarovsk. The research showed that the climatic conditions of the region promote the dust dispersal of toxic agents from the surface of the ash dump. The pollution of the air basin here can be attributed to the extremely high level of pollution (EHP), the priority pollutant is the dust containing heightened concentrations of heavy metals (Pb, Mn, Cu, Cr, Co, Ni, Cd). As a result it leads to the deterioration of the population’s health, especially to the high level of respiratory organs diseases. The research of the sprouting of the herbaceous plants (mixture of timothy-grass, clover and mustard) on prepared model soils showed their healthy growth. The ash chemical composition was studied. It showed high concentration of toxic chemical elements (Hg, Be, Sr, Cd, V, Th, 40K, Cr, Mb, AS, Sb,Se, Te, Pb, Ni, Co). The migration intensity of heavy metals ions into the plants was analyzed. On the basis of the experimental research the optimum composition of the substrate was revealed and recommended for recultivating the ash dump of PS1, namely: soil+sand+ash. Climatic conditions of the Khabarovsk Krai do not permit to recommend the sand+ash substrate for recultivation because of strong winds.
