    Studies were carried out to investigate how sludge applied to 3 soil types to improve the yield of carrots (Daucus carota) and spinach (Spinacea oleracea) would affect the amount of Zn taken up by thesevegetables. A 3 year old (type 1 sludge) and a 3 month old (type 2 sludge) sludge were applied to a vertisol, an arenosol, a chromic/calcic luvisol and a ferric luvisol at (v/v, %) ratios of 0:100, 5:95, 10:90,20:80, and 40:60 sludge : soil. Spinach and carrots were grown on these soil-sludge mixtures for 9 and 13 weeks, respectively, after which the concentration of Zn in both was determined. Sludge applicationresulted in an increase in total Kjeldahl nitrogen (TKN), available phosphorus, organic matter content, (OM) and cation exchange capacity (CEC) of soils. Percentage increase varied with soil type but rangedfrom 900 - 3600%, 700 - 3000%, 60 - 300% and 9 - 600% for TKN, available phosphorus, OM, and CEC, respectively. Sludge application also increased the fresh weight of spinach by up to 31% and carrots byup to 10%, these increases also varied with type of soil on which vegetable was grown. Spinach accumulated more Zn than carrots. Carrots and spinach grown on the arenosol had the highest mean concentration of Zn with values of 131.58 mg/kg and 86.33 mg/kg, respectively. Soil type, sludge age and sludge application rate may not individually affect the amount of Zn accumulated by these vegetables, but they could interact to increase the uptake

    Gold mining is a major source of metal and metalloid emissions into the environment. Studies were carried out in Krugersdorp, South Africa, to evaluate the ecological and human health risks associated with exposure to metals and metalloids in mine tailings contaminated soils. Concentrations of arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), lead (Pb), manganese (Mn), nickel (Ni), and zinc (Zn) in soil samples from the area varied with the highest contamination factors (expressed as ratio of metal or metalloid concentration in the tailings contaminated soil to that of the control site) observed for As (3.5x102), Co (2.8x102) and Ni (1.1x102). Potential ecological risk index values for metals and metalloids determined from soil metal and metalloid concentrations and their respective risk factors were correspondingly highest for As (3.5x103) and Co (1.4x103), whereas Mn (0.6) presented the lowest ecological risk. Human health risk was assessed using Hazard Quotient (HQ), Chronic Hazard Index (CHI) and carcinogenic risk levels, where values of HQ > 1, CHI > 1 and carcinogenic risk values > 1Γ—10-4 represent elevated risks. Values for HQ indicated high exposure-related risk for As (53.7), Cr (14.8), Ni (2.2), Zn (2.64) and Mn (1.67). Children were more at risk from heavy metal and metalloid exposure than adults. Cancer-related risks associated with metal and metalloid exposure among children were also higher than in adults with cancer risk values of 3Γ—10-2 and 4Γ—10-2 for As and Ni respectively among children, and 5Γ—10-3 and 4Γ—10-3 for As and Ni respectively among adults. There is significant potential ecological and human health risk associated with metal and metalloid exposure from contaminated soils around gold mine tailings dumps. This could be a potential contributing factor to a setback in the health of residents in informal settlements dominating this mining area as the immune systems of some of these residents are already compromised by high HIV prevalence

    This study was designed to characterize sludge of three different ages (36 months old, 3 months old and fresh sludge referred to as Type 1, Type 2 and Type 3 sludge respectively) in an endeavor to appreciate their suitability for use as manure for arable agriculture. Sludge properties including volatile solid and nutrient contents, concentrations of the heavy metals As, Cd, Cr, Co, Cu, Mn, Pb, Ni and Zn as well as coliform population were determined. The concentrations of plant nutrients in the sludge followed the order Type 3 sludge > Type 2 > Type 1 sludge with nutrient content scores of 1.4, 2.1 and 2.6 respectively. Scores for potential leachability of heavy metals from the three sludge were 2.1, 1.9 and 2.3 for Type 1, 2 and 3 sludge respectively, indicating that Type 2 sludge would release a higher concentration of heavy metals to the environment than the other two sludge types. The faecal coliform population in Type 3 sludge was higher than in Types 2 and 3 sludge with values of 5.6log10MPN/10g dry solid, 4.6log10MPN/10g dry solid and 2.7log10MPN/10g dry solid respectively. These results revealed that the nutrient contents and heavy metal concentrations in the three sludge types may not hinder their application to soil for arable purposes but steps to allow for further pathogen reduction need to be taken to reduce health risks.

    Human health aspects related to the ingestion of geophagic clayey soils from the Free State and Limpopo provinces, South Africa

    Get PDF
    Published ArticleStudies were undertaken in the Limpopo and Free State Provinces of South Africa to understand the beliefs, perceptions and health implications associated with geophagia. Questionnaires administered to 225 geophagic females covered their demographic details, their reasons for ingesting geophagic clayey soils and their perceptions regarding associated health conditions and implications. Respondents ingested clayey soils for body cleansing, craving, nutrient supplementation and weight loss. Some respondents considered the soils harmful, and < 50% of respondents had some knowledge of the contents of soils they ingested. Medical reasons in support of geophagia included lack of knowledge on the health implications of the practice. Medical consequences associated with geophagia may have occurred as a result of a lack of knowledge of the health implications of the practice. A clear need for educating geophagic individuals regarding the health implications of geophagia is called for

    Landslides are part of natural catastrophic disasters destroying both biological and physical entities including loss of human lives. An evaluation of soil properties involved in landslides is significant in itsmanagement. To this effect, soil samples from the 2001 landslide occurrences in the Mabeta New Layout, Limbe, Cameroon were analysed using standard techniques to determine texture, pH, electrical conductivity (EC), bulk density (Db), water absorption percent (WA), linear shrinkage, plasticity index (PI), loss-on-ignition (LOI),mineral content and major cations. Results obtained were: bulk density (0.89 – 1.08 g/cm3), LOI (19.4 - 25.7%), water absorption (23.4 – 29.1%), linear shrinkage (5.4 – 8.3%), volume shrinkage (4.8 – 8.5%), PI (13.5 –20.75%), major cations ((Fe2O3 : 9.91 – 23.24%), (Al2O3 : 9.88 – 28.48%), (CaO : 0.73 – 1.3%), (MgO : 0.55 –2.80%), (K2O : 1.06 – 1.59%), (Na2O : 0.77 – 0.89%)), pH (5.17 – 6.90) and EC (16.53 – 149.20Γ¬S/cm). Values from physico-chemical analyses, secondary minerals abundance index (SMAI) and chemical index of alteration (CIA) of the soils were reflective of particles with high potential for sliding. With major contributions from favourable slope, seismic and hydrologic forces, the event occurred
