“…As DDD and DDE are the transformation products of DDT (Boul 1995) formed as a result of microbial activities, the results obtained indicate that the microbial pool enhanced by glucose addition contained microbial species able to degrade DDT to DDD and DDE. Carbon sources may influence the degradation rates in soils.…”

A 12-day incubation experiment with the addition of glucose to soils contaminated with persistent organic pollutants (POPs) was carried out in order to estimate the potential microbial activities and the potential of the soil microbial biomass C to degrade 1,1,1-trichloro-2,2-bis(p-chlorophenyl) ethane (DDT), polychlorinated biphenyls (PCB) and polycyclic aromatic hydrocarbons (PAHs). The microbial activities were affected in different ways depending on the type of pollutant. The soil organic matter also played an important role. The microbial activities were affected particularly by high concentrations of PAHs in the soils. Soil microorganisms in the PAHs contaminated soil used the added glucose to a lesser extent than in the non-contaminated soil, which in the contaminated soil resulted in a higher microbial biomass content during the first day of incubation. DDT, DDD and DDE, and PCB affected the soil microbial activities differently and, in comparison with control soils, decreased the microbial biomass C during the incubation. The increased microbial activities led to a significant decrease of PAH up to 44.6% in the soil long-term contaminated with PAHs, and up to 14% in the control soil after 12 days of incubation. No decrease of PAHs concentrations was observed in the soil which was previously amended with sewage sludges containing PAHs and had more organic matter from the sewage sludges. DDT and its derivates DDD and DDE decreased by about 10%, whereas the PCB contents were not affected at all by microbial activities. Studies on the microbial degradation of POPs could be useful for the development of methods focused on the remediation of the contaminated sites. An increase of soil microbial activities caused by addition of organic substrates can contribute to the degradation of pollutants in some soils. However, in situ biodegradation may be limited because of a complex set of environmental conditions, particularly of the soil organic matter. The degradability and availability of POPs for the soil microorganisms has to be estimated individually for each contaminated site.

“…DDD and DDE are transformation products of DDT (Boul 1995), formed by microbial action (Wedemeyer 1966) or by chemical or photochemical reactions (Baxter 1990). The mechanism of microbial degradation of DDT to DDD is the reductive dechlorination under reducing (Johnson 1976;Rockind-Dubinsky et al 1987) or under aerobic conditions (Nadeau et al 1994).…”

“…The situation is different for pp'DDE: in this case the downward trend is less marked, probably because this compound has higher persistence and mobility (Boul 1995) than pp'DDT. On the other hand, little is known about the biodegradation of pp'DDE (Aislabie et al 1997), which can presumably vary greatly in different environmental conditions.…”

“…DDT is the first of the chlorinated organic insecticide that was originally prepared in 1873, but it was not until 1939 that Paul Muller of Geigy pharmaceutical in Switzerland discovered the effectiveness of DDT as an insecticide (Melanby, 1992). The unusual persistence of DDT is one feature of the insecticide that was initially attractive, because of the potential for long-term control of pests without re-application (Boul, 1994). In the 1950's, DDT was used in agriculture in far larger quantities than against malaria mosquitoes which probably led to its ban for agricultural purposes in United States of America and some other countries (Enger et al, 1998).…”

Malaria, a disease that has increasingly been ravaging human population still has no sustainable remedy.Therefore, mosquito diversity and impact of house treatment with dichlorodiphenyltrichloroethane (DDT) on their population were investigated by the use of miniature Centre for Disease Control light trap (model 512) and WHO -approved compression sprayer in Amauro, Okigwe Local Government Area, Imo State, Nigeria. A total of 9,114 adult mosquitoes belonging to Anopheles, Aedes and Culex genera were captured and identified in this study prior to the DDT indoor residual spray. Virtually all the living houses (93) in the area were treated with a total of 25kg of DDT active ingredient (concentration of DDT active ingredient: 10%). Mosquito populations reduced significantly (P<0.05) by 89.82% six months after house treatment with DDT. This shows that DDT insecticide is highly effective in controlling mosquito vectors. Mosquito species incriminated by this study suggest serious public health implications in the area.
