1 Analysis of Trace Metal by FAAS Based on the table (4.3 and 4.4) the trace elements was detected by using the flame atomic absorption spectrophotometry analysis. The trace metal can be detected by the FAAS within 15 seconds to 30 seconds of each soil sample. Before the samples were analysis with the FAAS‚ the blank samples were run in the machine for each element that was being analyzed. Their absorbances were read. The mean of each blank was calculated and hence the detection limits determined

Effect on plants Nitrogen fixation‚ which is required for the growth of higher plants‚ is hindered by pesticides in soil. The insecticides DDT‚ methyl parathion‚ and especially pentachlorophenol have been shown to interfere with legume-rhizobium chemical signaling. Reduction of these symbiotic

an excellent rotation crop of cotton‚ maize‚ groundnut‚ wheat‚ and sorghum. It reduces nematode populations that attack cotton and groundnut. It is also an excellent soil builder- it improves the soil texture and moisture retention and lessens soil erosion: the composted sesame leaves left on the soil binds the ground; retains soil moisture better for planting the next crop; increases the yield of the following crop. Sesame is resistant to drought‚ tolerant to insect pests and diseases‚ a low cost

People must take lessons from it. When the scale of contamination is too large‚ it will be too expensive and even impossible to make the water clean once you contaminate it. Any individual should be a good police in this sense; the law enforcement sector must act accordingly. Without serious and strict law

Ground water contamination: Chemicals can reach underground aquifers if there is persistent product use in agricultural areas. Resistance: Overuse of the same pesticide can encourage resistance in the target pest. Poisoning hazards: Pesticide operators can risk poisoning through excessive exposure if safe handling procedure are not followed and protective clothing is not worn. Poisoning risks depend on dose‚ toxicity‚ duration of exposure and sensitivity. 5) plants can grow without soil‚ but they

The waste of an open dump would decay and form part of the soil as organic manure. • Land Filling A landfill site (also known as tip‚ dump‚ rubbish dump or dumping ground and historically as a midden) is a site for the disposal of waste materials by burial and is the oldest form of waste treatment.

Procedure- I will first visit a site that has previously has heavy industry located on it. Using protective clothing‚ goggles and gloves I will extract several samples of the soil from the site and then take several other samples from different points on the site. This ensures variety of soil to ensure that all the site is safe‚ not just a small area where you
