“…Other higher amount of Zn in stem and leaf of the plant were found on 180 and 120 harvesting days with a concentration 29.75 ± 4.40 and 27.88 ± 2.21 mg/kg respectively. This study agreed with the similar experiment carried out on Zn uptake using different plant species by Subhashini et al, 40 , they reported that Acalypha indica and Ruellia tuberosa accumulated Zn in the tissues following the trend root > stem > leaf. 40 .…”

This study was to assess the phytoremediation potential of Polyscias fruticose in the removal of heavy metals from spiked soil. P. fruticose cuttings were transplanted then grown on 2.00 kg soil spiked with several heavy metals in polyethylene bags. The experiment was conducted for 300 days and concentrations of heavy metals in plant and soil over the growth period were determined. Appreciable concentrations of heavy metals in P. fruticose parts were obtained. The indices used to show the ease of heavy metals uptake and translocation indicated that Co, Cr, Mn, Ni and Pb displayed the greatest ease of absorption while Zn, Fe and Cu were accumulated in the root but not translocated to the shoot. The results obtained shows that this study pioneered the use of P. fruticose in the phytoremediation of several heavy metals spiked soil at a greenhouse level.

“…In the treatment of C2 and C3, there was a reduction of potassium (12 mg/ kg, 16 mg/kg) and phosphate (53 mg/kg, 61 mg/kg), but in C4 and C5, the micro-organisms in the soil were unable to uptake these minerals, due to the high concentration of sludge 20 . Helianthus annuus was able to uptake Pb and Ni from ETP mixed soil (72 mg/kg and 44,410 mg/kg), which was quite low compared to the plant Catharanthus roseus which up took Pb and Ni by 67.34 mg/kg and 45.75 mg/kg 21 . Helianthus annuus was able to survive and uptake chromium (183704 mg/kg) from pre-treated sludge.…”

Phytoremediation is one of the best methods in the treatment of sludge from industries because the pollutants present in the sludge are the food source for plants. So, the present study dealt with wedging the electro-plated sludge with red soil for 30 days and using it for the growth of Helianthus annuus L. The sludge and soil were blended in different concentrations C1, C2, C3, C4, C5 and C6 (for the pre-treatment). Physicochemical parameters (pH, ammoniacal nitrogen, potassium and phosphate) and heavy metals (Ar, Cd, Pb, Hg, Ni and Cr) of raw sludge, soil and ETP-treated-sludge with soil were analysed. After inspecting the physicochemical parameters of raw sludge and treated sludge, the soil-treated-sludge was used for the growth of Helianthus annuus L. Phytoremediation by Helianthus annuus L. has made considerable changes in the physicochemical properties of the soil, specially denoting the reduction of chromium. Thus, the work concludes that the pre-treated sludge provides a pathway for the uptake of heavy metals through the process of phytoremediation.

“…Similarly, the rocks in southern India are rich with fluoride which forms the major reason for fluoride contamination in groundwater , and the granites in the districts of Andhra Pradesh contain much higher fluoride than the world average fluoride concentration of 810 mg/kg . Fluorosis was first detectedin India, among cattle and humans in Andhra Pradesh .In India, approximately 60-65 million people drink fluoride contaminated groundwater, and the number affected by fluorosis is estimated at 2.5-6 million, predominately children [5][6]. In India, the excessive presence of fluorides in groundwater is present in nearly 177 districts covering 19 states.…”

A Review on the Role of Chemical Nature of Fluoride on Human Health and Environment

The review of this article is focusing on role of chemical nature of fluoride on human health and environment. Fluoride has both positive and negative effects on human health and environment. However this positive effect is felt when the fluoride concentration is low. At higher concentration the negative affects of fluoride far out way its positive effects. Millions of people all over the world presently suffer from a debilitating bone disease called skeletal fluorosis and also from dental fluorosis. Apart from dental and skeletal fluorosis fluoride also affects many vital organs of the body. Scientists and Doctors across the world have worked extensively on the health impacts of fluoride on humans and animals and found that fluoride has tremendous impact on the living system. The only remedy is prevention by keeping fluoride intake within the safe limits. Fluoride poisoning can be prevented or minimized by using alternative water sources, removing excess fluoride, and improving the nutritional status of the population at risk. Clinical data indicate that adequate calcium intake is clearly associated with a reduced risk of dental fluorosis. Vitamin C may also act as a safeguard against the risk. Therefore, measures to improve the nutritional status of an affected population, particularly in children, appear to be an effective supplement for an antidote against fluorosis.
