“…A reduction in redox potential as a result of submergence has been shown to cause changes in metal‐oxidation state, formation of new, low‐soluble minerals, and reductive dissolution of Fe and Mn, which can result in the release of associated metals into solution (Chuan et al, 1996; Amrhein et al, 1994; Masscheleyn et al, 1991). The influence of submergence on micronutrient and contaminant lability has long been studied, especially for paddy soils in relation to plant uptake of nutrients and contaminants (Kirk, 2004; Adriano, 1986). However, there has been limited research undertaken to examine the lability of metals in soils that have been exposed to more typical, short‐term changes in soil moisture regimes (e.g., submergence and drying).…”

“…Anthropogenic sources of Co have increased Co concentrations in some soils (Wendling et al, 2009b). Geochemically, Co behaves similarly to Ni and behavior is closely linked to that of the Fe–Mn system; however, unlike Ni, Co exists naturally in two oxidation states, Co(II) and Co(III) (Adriano, 1986; Kabata‐Pendias and Pendias, 2001). Taylor and McKenzie (1966) demonstrated that in widely different types of Australian soils.…”

Cobalt Distribution and Speciation: Effect of Aging, Intermittent Submergence, In Situ Rice Roots

et al. 2011

The speciation and distribution of Co in soils is poorly understood. This study was conducted using x-ray absorption spectroscopy (XAS) techniques to examine the influence of soluble cobalt in the +2 oxidation state (Co[II]) aging, submergence-dried cycling, and the presence of in vivo rice roots on the speciation and distribution of added Co(II) in soils. In the aging and submerged-dried cycling studies, Co was found to be associated with Mn oxide fraction (23 to 100% of total Co) and Fe oxide fractions (0 to 77% of total Co) of the soils as either Co(II) species or a mixed Co(II), and Co in the +3 oxidation state (Co[III]) species. The surface speciation of Co in the Mn oxide fraction suggests an innersphere complex was present and the speciation of Co in the Fe oxide fraction was an innersphere surface complex. The in vivo root box experiments showed similar Co speciation in the Mn oxide fraction (13 to 76% of total Co) as the aging and submerged-dried cycling studies. However, the Fe oxide fraction of the soil was unimportant in Co retention. A significant amount (24 to 87% of total Co) of the Co in root box treatments was identified as a Co precipitate. The importance of this finding is that in the presence of rice roots, the Co is redistributed to a Co precipitate. This work confirmed earlier macroscopic work that Mn oxides are important in the sequestration of Co in soils and the influence of roots needs to be taken into account when addressing Co speciation. The information gained from this study will be used to improve models to predict the lability and hence the availability of Co in terrestrial environments.

“…In higher plants, Co supplements have been reported to increase growth of rubber plants and tomatoes and to have increased the elongation of pea stem sections (Adriano 1986). Cobalt is essential for nitrogen fixation by free-living bacteria, blue-green algae, and symbiotic systems.…”

“…Cobalt is a constituent of vitamin B 12 , which is required by all animals. Some plants appear to accumulate Co, and several hyperaccumulator species have been reported to inhabit mineralized areas (Adriano 1986). Generally, the higher plants are reported to contain less than 1 ppm Co (on dry weight basis).…”

Tomato (Lycopersicon esculentum L.) cv. Alivikas was grown in refined sand at two levels of phosphorus (P): 1.5 mM (adequate) and 3.0 mM (high); 0.5 mM cobalt (Co) was supplied at each P level after 35 days of growth. Visible symptoms of Co toxicity appeared as interveinal chlorosis of young leaves after 8 days of metal supply. Biomass was depressed at both P levels with excess Co, although less at the high P level. Discontinuation of high P or Co or additional iron (Fe) supply also increased the biomass. The fresh weight of fruits was decreased, but dry weight was increased in high P supply. Quality of fruits was poor with Co-treated plants as Co depressed the fruit fresh weight and dry weight, volume and size of fruits, concentrations of chlorophyll a, b and carotene, ascorbic acid, lycopene, reducing sugars, and starch, and increased acidity and phenols. These effects were greater with adequate vs. high P. High P (without Co) improved fruit quality by increasing fruit dry weight, volume, and size of fruits, ascorbic acid content, and reducing sugars and by decreasing acidity. Accumulation of cobalt in leaves and fruits was greater, and these plant parts developed visible Co toxicity symptoms. Fruits developed black patches with prolonged Co supply. New fruits developed after the discontinuation of the Co supply appeared green and normal, but were few in number compared with increased vegetative growth of plants (cobalt supplied with the normal level of phosphorus). Earlier flowering, fruiting, and ripening were observed in plants with high phosphorus rather than adequate P. Brown spots in fruits developed after 18 -20 days of Co supply, and in the most severe case, young emerging fruits were totally brown. Amelioration of cobalt toxicity was better with discontinuation of Co than withdrawal of high P with additional Fe.

“…The presence of various metals, such as chromium, nickel, copper, manganese, mercury, cadmium, and lead, as well as metalloids, such as arsenic, antimony, and selenium, in the natural environment, is a major concern (Adriano, 1986), especially in close proximity to textile sites, landfills, tanning areas, and impoundments, as well as in urban areas and industrial hubs. Due to past industrial operations, which may have resulted in the development of the more bioavailable forms of certain elements, water in these places may contain greater than usual abundances of these elements.…”

Textile wastewater pose a significant threat to surface water especially the water bodies closer to the textile industry locations. The study investigated the bioavailability of cobalt (Co), copper (Cu), lead (Pb), nickel (Ni) and chromium (Cr) in wastewater from ten sampling points including wastewater from point of effluent discharge in Funtua textile across Funtua region. The trends in the metal bioavailability (mg/L) among the fractions were; Zn Cu: total> mobile > dissolved > particulate; Pb: total> particulate > mobile> dissolved; Ni: total> particulate > dissolved> mobile; Cr: total > particulate > mobile > dissolved, respectively. All the concentrations of the metal ions were above the WHO (2006) and USEPA (2000) tolerable limits across the sites, with the exception of Co which was not detected in all the fractions. While lead and chromium was detected in S1, S2 and S1, S10, respectively. The order of the metals bioavailability was; total>mobile>dissolved>particulate, with more than 50% found in the bioavailable phase. Hence, the surface waters within the vicinity of the textile industry were greatly at risk of being polluted by these toxic metals and subsequently affecting the inhabitants who use the water for agricultural and other domestic activities untreated, through the food chain transfer. The health implications associated with the toxic metals include an irreversible damage to nervous system, gastric and intestinal disorder, heart disease, liver, brain damage, mental retardation and teratogenic effects.
