The effect crude oil pollution and amendment treatments using decomposed green manure (Calopogonium muconoidesDesvaux andAspilia africana(Person) C.D.Adams) on the growth and neutraceutical (minerals, proximate and vitamins A and C) ofCucurbita maximawere studied. Crude oil polluted soils were obtained by mixing thoroughly 10 kg of sandy-loam soil with 10, 20, 30, 40 and 50 ml of crude oil, 0 ml served as control. The amendment treatment with green manure ofC. muconoidesandA. africanawas carried out by adding the different levels of crude oil polluted soils (10 – 50 ml) with 4 kg of the compost manure. The experimental work was carried out in the green house using plastic buckets. Measurement of selected growth parameters such as percentage germination, vine length, leaf area, internode length, leaf number and petiole length was carried out after nine (9) weeks. The results indicated that crude oil pollution significantly (p=0.05) reduced the growth parameters ofC. maxima. Mineral content, proximate composition and vitamin A and C contents ofC. maximaalso showed pronounced reduction with increase in crude oil concentration. The addition of amendment treatment with green manure ofC. muconoidesandA. africanato ameliorate the impeding condition in the crude oil polluted soil significantly (p=0.05) improved the growth parameters and neutraceutical composition ofC. maximawhen compared to the pollution treatment. This study revealed that crude oil pollution negatively affected the growth and neutraceutical composition and generally the productivity ofC. maxima. From this study, it is evident thatC. muconoidesandA. africanaenhanced the growth and quality ofC. maxima.Therefore,C. muconoidesandA. africanashould be used for effective and efficient bioremediation practices.

Blue mussels, Mytilus edulis, inhabiting tidal zones, are naturally exposed to fluctuating environmental conditions (e.g., fluctuations in temperature and salinities), while horse mussels, Modiolus modiolus, live under relatively invariable shelf water conditions. The present investigation tested the hypothesis: blue mussels, in comparison to horse mussels, have an increased ability to tolerate the stress of pollution combined with low salinity. To assess the response of blue mussels and horse mussels to oil pollution at seawater salinities of 25 psu (normal) and 15 psu (low), we used a combination of heart rate and lipid composition as physiological and biochemical indicators, respectively. A sharp decrease in heart rate as well as important fluctuations in cardiac activity was observed under all oil concentrations. Modifications in the concentrations of the main membrane lipid classes (phosphatidylcholine, phosphatidylethanolamine, and cholesterol) and storage lipids (primarily triacylglycerols) in response to different crude oil concentrations were time- and dose-dependent. Both chosen indicators showed a high sensitivity to crude oil contamination. Furthermore, both bivalve species showed similar responses to oil pollution, suggesting a universal mechanism for biochemical adaptation to crude oil pollution.

The increasing concentrations (10, 25, 50, 75 and 100 mg /kg) of soil cadmium on growth and biochemical contents in tomato plants were analysed on 30th sampling days. Control plants were maintained separately. Plants were grown in pots containing 3 kg of air dried sandy loam soil and treated with different concentrations (mg/kg) of cadmium (0, 10, 25, 50, 75 and 100 ). Treatments decreased the growth parameters such as root and shoot length  and biochemical constituents such as, protein,(except, proline and  phenol content) contents in tomato plants compared to untreated plants. The shoot length of cadmium treated tomato plants was higher than the root length. proline and phenol content of root of  tomato plants was higher than the shoot.

This study was undertaken to investigate the effects of Bonny light crude oil contamination of sandy loam soil on aspects of microbial metabolism and physicochemical properties of the soil. Bonny light crude oil (specific gravity = 0.81) was used at eight different levels (0.5%, 1.0%, 2.0%, 2.5%, 5.0%, 10.0%, 15.0% or 20.0% v/w of soil) for the controlled pollution of pristine soil samples, each weighing 1 kg. The experiment lasted for eightweeks. Results of the effects of crude oil on the physicochemical properties of the soil showed that high levels of the oil significantly (p< 0.05) increased soil organic matter but had no significant effect on the pH and moisture content. With the exception of organic carbon, the levels of bioavailable nitrogen, sodium, potassium, calcium, magnesium, sulphur and phosphorus in the test samples with higher levels of crude oil (5.0%, 10.0%, 15.0% and 20.0%) were significantly reduced when compared to their levels in the controls. Similarly, higher levels of the oil significantly (p<0.05) reduced soil microbial phospholipid synthesis and CO emission. 2 Correlation analysis using the Pearson's correlation model showed a positive correlation between soil CO and 2 phospholipid (r = 0.74).
