Effect of Municipal Solid Waste Open Dumping on Soil, Water, Crop, Human Health and Its Prospectives

Characterization of heavy metals in 5 Km2 range of dumping yard in relation to soil, water and crop has been studied. The concentration of Cd (4.05 mg/kg) in soil was higher than the permissible limit of WHO (3 mg/kg) and in descending order of metals in soil was found to be Fe> Cr>Cd>Ni>Zn>Cu>Pb and in bore well water it was Cr, Fe, Pb, Cd, Zn and Cu (23.20, 0.63, 0.31, 1.19 and 0.69 mg/l respectively) than the permissible limit (0.54, 0.40, 0.068, 0.03, 0.22, 0.018 mg/l) and their respective concentration ordered as Fe>Zn>Cu>Pb>Cd>Ni>Cr. Further the vegetables grown nearby dumping yard was highly contaminated by Cr in range (2.78 to 12.78 mgkg-1) in tomato, beans and cabbage and even in ragi and green gram Cr was high (1.78 to 14.96 mgkg-1). i.e., in Tomato; Cd>Fe>Cr>Zn>Pb>Ni>Cu, Beans; Cr>Cd>Pb>Fe>Zn>Cu>Ni, Cabbage; Cr>Cd>Pb>Fe>Zn>Cu>Ni, Ragi; Fe and Zn were below permissible limit and Pb, Ni, Cu, Cd are BDL and Green gram; Cr>Fe>Zn>Pb>Cu > Ni>Cd. In support of results, primary survey was conducted in nearby 20 villages circumventing the dumping yard. A total of 150 respondents were randomly enquired to know their level of knowledge and health status as result of open dumping site. The results revealed that 43.33%, 36% and 20.67% as medium, high and low impact in relation to heath and knowledge aspect of dumping site. Thus there is a considerable impact on environment and humans due to the presence of heavy metal in crop, soil and water.

Congenital third nerve palsy with synergistic depression on attempted adduction and trigemino‑oculomotor synkinesis: Underpinnings of a spectral dysinnervation disorder.

The authors describe a case of congenital partial pupil‑sparing third cranial nerve palsy with absent adduction, synergistic depression of globe and widening of palpebral fissure on attempted adduction and synergistic elevation and adduction on mouth opening and sideways thrusting of jaw. The case illustrates trigemino‑oculomotor synkinesis associated with congenital third nerve palsy. The possible mechanism of miswiring involving the medial longitudinal fasciculus and trigeminal nuclei is discussed. At least some cases of congenital third cranial nerve palsy may fall in the realm of congenital cranial dysinnervation disorders (CCDDs) sharing a much wider spectrum of presentation.
