Soil pollution with lead

Xem 1-14 trên 14 kết quả Soil pollution with lead
  • The study aimed to evaluate the concentration of heavy metals in the soil of industrial zones in An Giang province. Soil samples were collected at Binh Hoa and Binh Long industrial parks with 20 monitoring positions in the topsoil. The heavy metals including Copper (Cu), Zinc (Zn), Lead (Pb), Cadmium (Cd) and Arsenic (As) were analyzed by atomic absorption spectroscopy.

  • Turkey is the leading country in the world in terms of boron production and sale. Increasing boron production goes along with an increasing generation of boron wastes. The pollution of the soil and the air around the waste piles, as well as the occupation of several square kilometers of ground, are major environmental problems. It is, therefore, very important to make use of the wastes to both protect the environment and create revenue.

  • Phenol is a toxic hydrocarbon for nervous system, kidneys, liver, muscles and immune system. It is also mutagenic and possibly carcinogenic. Phenol containing- pollutants are dangerous and spread worldwide in the industrial effluents.The present study aimed to isolate a potent microorganism able to degrade phenol, as well as to evaluate the nutritional and environmental conditions that lead to its maximum degradation. A yeast isolated from petroleum-contaminated soil on MSM supplemented with phenol as sole carbon source, was identified by 28S rDNA sequencing.

  • Heavy metals like cadmium, nickel, lead, chromium, mercury etc are important environmental pollutants in areas with anthropogenic pressure. Their presence in the atmosphere, soil and water, even in traces can cause serious problems to all organisms. Heavy metal accumulation in soils is of great concern in agricultural production due to the adverse effects on food quality, crop growth (Ma et al., 1994) and environmental health. Heavy metal bioaccumulation in the food chain can be especially highly dangerous to human health.

  • Oilseed rape is the third largest oleaginous crop in the world but requires high levels of N fertilizer of which only 50% is recovered in seeds. This weak N use efficiency is associated with a low foliar N remobilization, leading to a significant return of N to the soil and a risk of pollution.

  • In recent scenario due to indiscriminate human activities the heavy metal pollution is very much concerned because of their toxicity for animal and human beings and their lack of biodegradability. Heavy metal toxicity is linked with a number of diseases but the severity of situation multiplies too many folds if these heavy metals are found in milk, which is the basic food item of vulnerable age group of people.

  • Lead (Pb) exposure is estimated to account for 0.6% of the global burden of disease with the highest burden in developing regions. Lead is considered as general protoplasmic poison, which is slow acting, cumulative and subtle. The use of leaded gasoline, discharges from industrial activities and other sources, and deposition by rainfall or dry fall can greatly influence the availability of Pb in soil, water, and other environments. Most of the Pb in plants and soil surface are anthropogenic origin.

  • The rampant uses of chemical pesticides by developing countries not only pollute the soil, also problem to environment and human. The current scenario is pollution of soil contaminated with heavy metals(HMs). Contamination of soil bad impact on both yields and crop qualities leads to decrement of agriculture productivity.

  • Rice is commonly grown by transplanting of seedlings into puddled soil, which is not only intensive water user but also cumbersome and laborious. Looming, fresh water scarcity, water pollution, competition for water use, growing population, rising demand for food, climate change and global warming, water-intensive nature of rice cultivation and escalating labour costs have threatened the puddled transplanted rice system. The excessive utilization of natural resource bases and changing climate are leading to the negative yield trend and plateauing of rice productivity.

  • It was examined that weeds cause a lot of problems in the crop field. Weeds compete with the main crop for nutrients, water, food, space, sunlight etc. Weeds utilize the nutrients provided to the main crop and sometimes dominate the main crop. Some weeds are very noxious and they are harmful for both humans as well as animals. It is clearly revealed from studies done in field of weeds that use of herbicides used to control weeds cause many effects on soil as it leads to degradation in the quality of soil, water as well as it pollutes environment.

  • In this paper, a model is presented for predicting the transport of an environmental pollutant from the source to and through the soil. The model can predict the deposition of an environmental pollutant on the soil surface due to the pollutant being loaded on dust particles, which are later deposited on the soil surface.

  • Lead (Pb) is one of the most toxic and persistent elements, with no known biological role. High concentrations of lead enter saline soils through anthropogenic activities and industrial waste. The decontamination of Pb polluted sites through phytoremediation, especially by using woody plants, is an attractive approach.

  • Some particles may be absorbed into the tree but most are retained on the plant surface. Some particles will be re-suspended, but others will be washed off (particularly soluble particulates) or fall with leaves or twig fall. This may lead to pollution within the soil, however, Beckett et al. (2000a) argues that this will only be a major problem in countries using a high proportion of lead fuel. Re-suspension of fine particulates is less likely as they are easier embedded1 within the leaf boundary layer (Beckett et al., 2000b).

  • Soil erosion is a hazard traditionally associated with agriculture in tropical and semi-arid areas and is important for its long-term effects on soil productivity and sustainable agriculture. It is, however, a problem of wider significance occurring additionally on land devoted to forestry, transport and recreation. Erosion also leads to environmental damage through sedimentation, pollution and increased flooding. The costs associated with the movement and deposition of sediment in the landscape frequently outweigh those arising from the long-term loss of soil in eroding fields.
