Pollution of soils

The primary objective of this study is to elucidate the chemical speciation of copper (Cu) and conduct an assessment of the magnitude and probability of contamination of Cu in soil samples procured from the Pb/Zn mining, at the Hich village, Dong Hy district, Thai Nguyen province, in order to furnish critical data pertinent to the environmental stewardship of soil resources within this geographical domain.

The aim of research: Determination of greywater characteristics from some buildings in Hanoi city; Explaination of the principle of removing the main pollutants out of greywater by using laterite with multi soil layering engineering; Determination of decomposition rate coefficients of BOD5, COD and NH4 + -N. The number of laterite layer is calculated based on these coefficients; Successful greywater treatment from building by using laterite with Multi Soil Layering engineering and the treated effluent meet up the National Regulations

Industrial garden is a new approach, especially for competition in increasing pollution in the atmosphere. It helps easily to beautify the industrial areas. The lawn laid in vacant lands not only adds beauty but also cut down dust. These gardens are designed to reduce pollution and beautify the world. These units are the most sources of air, water, noise and soil pollution.

This paper presents the experimental results of the effect of microorganism fertilizer (MF) on growth, yield and accumulation of Cu in lettuce grown on soil contaminated by Cu. The results show that applying MF on soil that has a Cu content of 17.03-106.4 ppm has a positive affect on the height, fresh weight, total chlorophyll content and catalase activity of lettuce grown on that soil.

As the urban area has high population density and intensive anthropogenic activities, there are a great number of sources of heavy metals in cities, placing a considerable influence on human health. Emissions of heavy metals may come from domestic waste, chemical industry and transportation. These emissions have been continuously adding heavy metals to soils and they will remain present for many years even after the pollution sources have been removed.

This is the basis for the choice of soil treatment, irrigable water or the choice of plants with capacity of absorbing the desired metal to clean up arable land. Moreover, because it costs much money and time to handle soil, water in current conditions, we envisage the results of this kind of research will initially provide the basis for the selection of plant varieties suitable for the soil conditions and current pollution.

When water or soil has the presence of a metal at a certain level, the metal can inhibit or stimulate the absorption of other metals in plants. Therefore, the study on competitive absorption among metals in plants is very necessary. The aim of this study is to find out the competitive absorption between Cu2+ and Pb2+ from polluted soil to lettuce.

The US Environment Protection Agency defines arsenic as a persistent, bio-accumulative, and toxic chemical having the ability to accumulate in the air, soil, and water. In 1961, the pollution of arsenic was first discovered in Taiwan, and later in Belgium, Netherland, Germany, Italy, Hungary, Portugal, The Philippines, Ghana, USA, Chile, Mexico, Argentina, and Thailand. In 1992, the toxicity of arsenic was found as a disaster in West Bengal, India.

Pot and field trials were carried out using sediment dredged from the port of Bremen (Germany) and deposited in a settling basin near Bremen; the sediment is polluted with Cd and Zn. Five iron-bearing materials were added to the soil (1% pure Fe in soil dry matter) to immobilize the heavy metals: ‘Red mud from the aluminium industry, sludge from drinking-water treatment, bog iron ore, unused steel shot and steel shot waste.

Introduction: Diazine and triazine herbicides are being widely used in the world. These herbicides inhibit the electron-transport system in the higher plants and thus suppress the photosynthesis, resulting in the herbicidal action. These compounds are also important as pollutants for crops, soil and groundwater [1, 2]. The attention is usually directed toward chronic toxicities of the herbicides [3].

The Mekong River Delta (MD), the most downstream part of the Mekong river, is known as the biggest "rice bowl" of Vietnam. Currently, 2.4 million ha are used for agriculture. During the rainy season part of the Delta is flooded. Along the 600 kmcoast, the sea tide strongly influences the water quality by sea water intrusion. In addition, an area of 2-million ha is covered by acid sulfate soils. Also, the MD is very densely populated with intense associated water pollution.

This paper identifies five water environmental problems in the Delta that are the principal limiting factors of agricultural production and human health, i.e. (i) the salinity intrusion in the coastal areas, (ii) the effect of acid sulfate soils, (iii) the polluted water from human activities, (iv) the fresh water shortage in the dry season and (v) the flood in the rainy season. The discussion and conclusion present the people’s adaption strategies and water gorvernance issues in pursing sustainable management in the region.......
