The Impact

Background: Exploration/exploitation of crude oil has impacted positively on the Nigerian economy and negatively on its environment. This study assessed the impact presence of an oil well has on Manihot esculenta and quality of surface water in Aguleri, South Eastern Nigeria. Results: Cassava proximate results; moisture content (5.25), carbohydrate (71.38%), crude protein (9.10%), crude fibre (5.20%), ash content (4.01%) and crude fat (1.56%). Copper concentrations (13.8 mg/kg, WHO, 73.30mg/kg), Nickel (3.2 mg/kg, WHO, 67.9mg/kg), cadmium (0.2mg/kg WHO, 0.2mg/kg), all within permissible levels in Manihot esculenta, while Iron (158.5mg/kg, WHO 50mg/kg), manganese (7.0mg/kg, WHO 2mg/kg), chromium (6.1 mg/kg, WHO 0.05mg/kg), cobalt (2.5 mg/kg, WHO 0.1mg/kg) and lead (1.8 mg/kg WHO 0.3mg/kg) concentrations were higher than the WHO allowable levels. All parameters analyzed in water samples; (pH, 7.05; WHO, 6.5-8.5) (conductivity, 62.30 µs/cm, WHO 500 µs/cm) (turbidity, 3.3 NTU, WHO <5) (total dissolved solids 31.50 mg/l WHO, 500mg/l), (total suspended solids, 100mg/l, WHO 500mg/l) and (nitrate, 0.5 mg/l, WHO 50mg/l) were within WHO allowable limit. Manganese and cobalt concentrations in water sample were within allowable limits, while Iron, chromium, nickel and lead (two sampling points) were not. Ash values of cassava analyzed was high. Conclusion: Water and cassava sampled have high concentrations of heavy metals, probably due to contamination from crude oil exploration and/or oil spillage. This study recommends portable water for communities close to oil well for domestic use/irrigation. Furthermore, farming activities should be in areas far removed (>19.4km) from the oil well to mitigate contamination of surface waters and farm produce.

The Impact

Nowadays there is the problem of the effective treatment of dairy industry plants’ wastewaters. Industrial wastewaters of these plants have high concentrations of organic matters and differ significantly from domestic wastewaters. The method of intensification of dairy wastewaters treatment in Tyumen region, using probiotic «PIP Plus WATER» (Belgium) is considered in this article. The article presents the results of conducted research on the impact of the probiotic on such wastewaters indices as pH, chemical oxygen demand, anionic surfactants, ammonium, nitrites, nitrates and phosphates concentrations. The comparison among different ways of wastewater treatment with probiotics has been made. Based on obtained results technological scheme of local treatment plant of dairy industry plant has been suggested.

Method Approach

The industrial sector is one of the important sector in supporting the development of a region. Utilization of land around the river that is used for industrial activities will affect the quality of river water. The river can be polluted by waste personinating from industries that operating around the river. The catchment area that used for industry, agriculture, urban development, and the use of land for making roads (gravel or footpaths) can affect the flow of surface water and sediments that it brings to the river. Waste generated from industrial activities can pollute rivers which are a source of water for daily needs and affect the development of biota in them. This can affect river water quality

The thinly populated Balkhash District of Kazakhstan’s Almaty Region lies in the lower reaches of the Ili-Balkhash basin, which is shared by China and Kazakhstan. The district is arid and heavily dependent on inflows of surface water, which are threatened by the effects of upstream population growth, economic development, and climate change. The quality of drinking water from centralized water systems and tube wells in nine villages of the district was analyzed, and the organoleptic properties of water from these sources was also assessed by an expert and via surveys of local residents. Although most samples met governmental standards for the absence of chemical impurities, high concentrations of mineralization, chlorides, boron, iron, and/or uranium were present in some well water samples. Levels of these pollutants were as much as 4-fold higher than governmental maxima and as much as 16-fold higher than concentrations reported previously in surface water. All centralized water samples met standards for absence of microbial contamination, but total microbial counts in some well water samples exceeded standards. Organoleptic standards were met by all the water from five villages, but centralized water from one village and well water from four villages failed to meet standards based on expert judgment. Residents were, for the most part, more satisfied with centralized rather than well water, but there was no obvious relationship between the failure of water to meet standards and the locations or populations of the settlements. This is the first comprehensive assessment of groundwater used for drinking in the lower Ili-Balkhash basin, and although it relies on a limited number of samples, it nevertheless provides evidence of potentially serious groundwater contamination in the Balkhash District. It is thus imperative that additional and more detailed studies be undertaken.

Staple Crop

Cassava (Manihot esculenta Crantz) is the staple food source for over 850 million people worldwide. Cassava contains cyanogenic glucosides and can be toxic to humans, causing paralysing diseases such as konzo, and even death if not properly processed. Konzo epidemics are often associated with times of drought. This may be due to a greater reliance on cassava as it is drought tolerant, but it may also be due to an increase in cyanogenic glucosides. Episodic droughts are forecast to become more common in many cassava-growing regions. We therefore sought to quantify the effect of water-stress on both yield and cyanogenic glucoside concentration (CNc) in the developing tubers of cassava. Five-month-old plants were grown in a glasshouse and either well watered or droughted for 28 days. A subset of droughted plants was re-watered half way through the experiment. Droughted plants had 45% fewer leaves and lower tuber yield, by 83%, compared with well-watered plants. CNc was 2.9-fold higher in the young leaves of droughted plants, whereas CNc in tubers from droughted plants was 4-fold greater than in tubers from well-watered plants. Re-watered plants had a similar biomass to control plants, and lower CNc than droughted plants. These findings highlight the important link between food quality and episodic drought.

The Impact

Aboisso region is experiencing unprecedented agricultural activities. Cultural techniques such as the use of insecticides are harming the quality of water. This study aims to assess the impact of insecticides on the water quality in the Aboisso region. Thirty-one (31) water points (10 surface water and 21 groundwater) were sampled. The determination of physicochemical parameters as well as the multi-residue method used for insecticides analysis in the samples allowed us to achieve our objective. The result of the physicochemical analysis shows that the temperature of groundwater (27.91°C) is higher than surface water temperature (26.77°C). These waters are mostly acidic with a slightly lower pH for groundwater (6.46) compared to surface water (6.54). The conductivity is higher in groundwater (average of 130.46 µS/cm) as opposed to surface water (average of 43.50 µS/cm). After applying the multi-residue method, the results reveal the presence of nine (9) active ingredients. In surface waters, all these molecules, except Lambda-cyhalothrin and Deltamethrin, exceed the WHO guide values (0.1 µg/L). The highest concentrations recorded concern ethyl parathion and profenofos (8.24 µg/L and 8.04 µg/L respectively). In groundwater, it is rather Parathion-methyl, Profenofos, Dimethoate, Chlorpyriphos-ethyl, Lambda-cyhalothrin and Deltamethrin that are often at below WHO standards. However, the present study reveals that all of the water samples analysed were polluted, owing to anthropogenic used of insecticides in the region, and other chemicals with high concentrations of parathion-ethyl: 8.24 µg/L and profenofos: 8.04 µg/L. These waters are therefore unfit for human consumption.
