Establishment of phosphate (P) retention and release capacity of soils is essential for effective nutrient management and environmental protection. In this experiment, we studied the influence of soil properties on P desorption and the relationship between phosphate sorption and desorption. Among the soil series, the Ghior soil had the highest percent clay (59.32%) and free iron oxide (15241 mg·kg–1) content. Along the catena of the calcareous soils, percent clay contents increased. For sorption study, the soils were equilibrated with 0.01 M CaCl2 solution containing 0, 1, 2, 4, 8, 16, 25, 50, 100 and 150 mg·P·L–1 solution. For desorption, three extractants namely, SO42- (0.005 M) as na2SO4, HCO3- (0.01 M) as naHCO3 and distilled water were used at extractant to soil ratios of 30:1, 60:1 and 100:1 (v/w). Among the sorption equations, the Langmuir equation showed better fit to the sorption data at higher P concentrations. The amount of phosphate desorbed by all the three extractants increased significantly with the increasing extractant to soil ratios. Phosphate desorption by and water molecules was highly correlated with pH, percent clay and free iron oxide content of the soil. Significant positive correlation (r > 0.64, P L). Phosphate desorption by SO42- and water molecules was also positively correlated with Freundlich constant, n (r > 0.67, P 0 (r > 0.72, P –0.77, P L). The results suggest that freshly sorbed phosphate ions (inner-sphere complex forming species) can be readily desobed by outer-sphere complex forming species like sulphate and bicarbonate ions. Water molecules also desorbed significant amount of freshly sorbed phosphate from the soil colloids.

The unusualness in the critical frequency of different layers of earth’s ionosphere is commensurate to be associated with seismic events. We present study of critical frequency of F2 layer (denoted as f0F2) during some major earthquakes in South American region. We use the semi-empirical Barbier’s theorem of air-glow and define a parameter using the critical frequency and virtual height of F2 layer and named it as “F Parameter”. To investigate the variation of this parameter, we consider five large earthquakes in the junction of nazca plate and South American plate having magnitude greater than M > 6.5 and study the temporal variation of F parameter during these earthquakes. The F Parameter is measured using the ionograms as recorded from the Ionosonde in Jicamarca Radio Observatory (lat. 11.95°S, long 76.87°W) in Chile which lies within the earthquake preparation zones of these five earthquakes. We examine the F Parameter within a span of ±15 days during earthquakes and observed significant change in the evaluated F Parameter in 12 to 3 days prior to the earthquakes. The increment is over +3σ from the normal variation. We also observe significant changes during aftershock events. The solar geomagnetic indices were found to be low which ensures that these anomalies in F Parameter are due to seismic events.

We conducted a field survey on 53 workers in a battery factory, 52 solder workers, and 50 embroidery workers (control group). The average air lead levels at the workplaces of these three groups were 0.578 mg/m3, 0.0015 mg/m3 and 0.006 mg/m3 respectively. Clinical and biochemical studies revealed that the workers in Shanghai navigation Battery Factory were affected somewhat by the toxic effects of lead. The solder workers showed no significant abnormalities compared with the control group. A significant dose-response relationship existed between air lead levels and toxic effects. The early clinical manifestations observed were dysfunction of the central nervous system, dyspepsia, joint pain, and myalgia in the extremities. A positive association was observed between the prevalences of fatigue, mild abdominal pain, and joint pain and the blood lead (PbB), urine lead (PbU), and zinc protoporphyrin (ZPP) levels. The symptomatic threshold values for PbB, PbU, and ZPP were 30 μg/dl, 0.045 mg/L, and 40 μg/dl, respectively. Although the PbB, PbU, δ-aminolevulinic acid dehydratase (ALAD), free erythrocyte protoporphyrin (FEP), and ZPP levels could be used as criteria of lead exposure, the measurement of ZPP is the first-choice screening test for a preventive monitoring program. The motor and sensory conduction velocities in the median nerve were slower in the exposure group than the control group (pnduction velocity and intensity of lead exposure were not significantly correlated. no apparent effects on behavioral function were observed among the solder workers.
