The historical geography of the early modern heavy chemical industry in Britain has largely been ignored. This paper attempts to remedy this neglect by focusing upon the most important aspect of the inorganic sector in the nineteenth century
, the Leblanc alkali trade. Throughout a geographical perspective is emphasised and it is the evolving spatial pattern of industrial development which provides the central theme. Five periods of change are recognised, each associated with different factors

Accumulation rates of heavy metals (Cd, Cr, Cu, Mn, Pb, and Zn) retained in wetland sediments in northwest Indiana, downwind of the Chicago-Gary-Hammond industrial area, are quantified to assess anthropogenic influences on atmospheric fluxes. Metal

Tampere a joué un rôle de précurseur dans différents secteurs industriels (industrie textile, du vêtement, du cuir, des papiers et cartons, du traitement des métaux). Dans un contexte général de mutation industrielle, la ville a perdu une grande
partie de ses industries de base au cours des années 1970 et 1980. Le volume de la main-d'oeuvre a diminué de moitié, entraînant une hausse du chômage. Après la récession, la ville a expérimenté un développement rapide et inattendu, pour devenir l'un des
Transfer of industrial pollutants to the rural environment: a European problem in Pollutants and their ecotoxicological significance.
Study of the contamination of the rural atmosphere by industrial or urban plumes, and quantification of the contamination of agricultural soils by heavy elements in Belgium. A transfer of heavy metals towards rural environments was observed, where

In order to estimate the present-day polution levels in the ecosystem of the Selenga River Delta and to monitor the changes caused by the discharge of household refuse and industrial wastes, as well as the functioning of the agricultural and stock
farming, a study of the water and bottom sediments in the main branches of the Selenga River Delta was carried out. This study has determined the concentrations of heavy metals in river water and bottom sediments in its delta.

This study aimed to investigate heavy metal contamination in the sediments and zoobenthos in different mangrove ecosystems of southern China and to evaluate potential ecology risks of heavy metals in the sediment of mangrove ecosystems. Significant
differences among different geographical regions were observed for the contents of Cu, Zn, As, Cd, and Pb in the sediment, while no significant differences were found among different vegetations. Except for Pb, the heavy metal contents in 2 species of crabs
analysis (PCA) revealed that Cr, Cu, Zn and Pb were mainly derived from anthropogenic activities such as industrial effluents and domestic sewage.

This review discusses the research available on the sources and impacts of 3 heavy metals, (copper, zinc, nickel), and polycyclic aromatic hydrocarbon (PAH) contamination on macroinvertebrate communities in streams. The literature evidence
is compared with field evidence from a study of 62 source areas in headwater catchments with residential, urban, industrial and motorway land uses. It is suggested that forecasting the ecological status of watercourses would benefit from data on sediment
This paper provides a case study on the determination of heavy metal deposition based on the analysis of soil and vegetation samples in the southern part of Budapest (Isle of Háros). Here the total deposition of heavy metals was much higher than

with industrial sewage sludge and afforested with birch and pine seedlings. To evaluate the growth of tree seedlings, tree dry biomass, height, diameter, root/shoot ratio, specific root length, shoot and root length were calculated. Higher concentrations of heavy
metals and no significant increase in the biomass of trees on sewage sludge amended soil suggest an inhibitory effect of heavy metals on tree biomass growth. - (AM)

This paper describes an investigation of the Odra River in western Poland, where channelization works preceded an extended period of heavyindustrialization and documented riverine pollution. The study explores the distribution of sediment
-associated heavy metals stored within both former and contemporary groyne fields, constructed during channelization works. The results indicate that large and extensive sediment quantities of moderately polluted sediments are stored immediately along

Repetitions exist in the machine and engineering industries among the twin cities of Beijing and Tianjin, a problem of industrial location common all over the country. Despite the lack of clear division among different branches of the industry
there are still recognisable distinctiveness between heavy, medium, and light engineering. The local resources and historical trends of the cities should be developed further to match specific types with the potential and to promote specialization while making
