Lead Addition

AbstractEight genetically diverse tobacco types (Tsebelia of Agrinion, Samsun, Basma, Kabakulak, Burley, Virginia and Havana, belonging to Nicotianatabacum, and Brasilia belonging to N. rustica) were grown in pots in the greenhouse where lead acetate had been added to the soil at the rates of 0, 0.1, 1.0 and 10.0 g Pb/kg soil. In the field, 20 g Pb/m2 in two forms (nitrate and acetate) were applied to Burley and Kabakulak types. The greenhouse experiment showed that only the highest rate of lead addition to the soil reduced the leaf yield significantly. The higher yielding types (Havana and Samsun) were found to be the least tolerant, while Brasilia was the most tolerant. At all levels of lead addition to the soil the lead concentration in leaf was found to be highest in the first of the three harvests which were made. The relationship between log (lead level in the soil) and log (leaf lead concentration) seemed exponential. Although control treatments in the field and the greenhouse experiment showed comparable leaf lead concentrations, leaf lead concentrations at 20 g Pb/m2 in the field experiment were found to be higher than those at 1.0 g/kg soil in the greenhouse experiment.

The Relationship

This chapter studies the relationship between consumer fairness, political preferences, and policy uptake. Americans who support Donald Trump are especially likely to believe the government should be judged by the standards of private companies. New experimental evidence documents that, when politicians of both parties use consumer rhetoric, co-partisans of those leaders subsequently come to view politics in strikingly consumerist terms. In another experiment, results show that voters with low levels of political knowledge look most positively upon a hypothetical political candidate who promises cost-benefit alignability, compared to a candidate who promises more benefits than costs. The chapter then describes a field experiment administered in cooperation with a health insurance cooperative funded under the Affordable Care Act (ACA). A message that framed the cooperative as meeting the standards of cost-benefit alignability caused people to enroll in the cooperative.

SUMMARYAs zinc (Zn) fertilizer and water management affect the expression of Zn-enriched grain traits in rice, we studied the effect of Zn fertilizer and water management on Zn uptake and grain yield of different biofortification breeding lines and the possible biases in selection for high grain Zn content. The first field experiment showed that longer duration genotypes had higher grain Zn uptake rate than shorter duration genotypes during grain filling. In the first greenhouse experiment, neither application of Zn fertilizer at mid-tillering nor application at flowering significantly increased the grain Zn concentration. In the second greenhouse experiment, application of alternate wetting and drying (AWD) significantly increased the available soil Zn and plant Zn uptake but not grain Zn concentration. Terminal drying (TD) did not increase the available soil Zn or grain Zn contents. The second field experiment confirmed that differences in TD were not important in understanding differences between genotypes. Zn application is not always necessary to breeding trials unless there is a severe Zn deficiency and there is no need to carefully regulate TD prior to harvest.

The Relationship

The effect of superphosphate applications (0, 25, 50, 75, 100 and 125 kg P/ha to the soil surface) on the dry matter (DM) herbage production of dense swards of subterranean clover (Trifolium subterraneum cv. Junee) and yellow serradella (Ornithopus compressus cv. Tauro) was measured in a field experiment on deep, sandy soil in south-western Australia. The swards were defoliated with a reel mower at weekly intervals from 88 to 158 days after sowing, to a height of 2 cm for the first 9 cuts, 4 cm for the tenth cut and 5 cm for the eleventh cut. Yellow serradella was more productive than subterranean clover. Consequently, for the relationship between yield and the level of phosphorus (P) applied, yellow serradella supported larger maximum yields and required less P than subterranean clover, to produce the same DM herbage yield. Maximum yields of yellow serradella were 12-40% larger. To produce 70% of the maximum yield for yellow serradella at each harvest, yellow serradella required about 50% less P than subterranean clover. However, when yields were expressed as a percentage of the maximum yield measured for each species at each harvest, the relationship between yield and the level of P applied was similar for both species, and they had similar P requirements.

Background: The problem of heavy metal pollution is a serious problem in Indonesia. This metal has been known to be stored in the body for long periods of time as toxins accumulate. Preliminary test results BLL on workers in the metal casting Ceper, found as many as 16 (5.61%) BLL on workers is under (NAB) and 17 (5.28%) workers above (NAB). The research was conducted to determine the relationship between the exposure of lead (Pb) in blood with hypertension in foundry workers CV. Fortification Jaya Batur, Ceper, Klaten. Methods: It was an observational study with Cross Secional design. The population in this study were all workers CV. Jaya fortification. Samples are workers CV. Fortification Jaya who met the inclusion criteria.

The effects of (2-chloroethyl) trimethylammonium chloride (CCC) on triticale (cult Rosner) and oats (cult Harmon, Rodney) was evaluated agronomically. In a greenhouse experiment, the application of CCC at rates of 3.0 and 6.0 kg/ha at the three-leaf stage did not decrease the mature height of oats; but the higher rate reduced the mature height of triticale. At the five-leaf stage, both rates reduced the mature height of both species. In a field experiment, CCC was applied only at the five-leaf stage. The mature heights of both species were reduced by a rate of 3.0 kg/ha and a significantly greater reduction was obtained with 6.0 kg/ha. These reductions were less under a high nitrogen regime. Lodging of oats, which occurred only under high nitrogen, was reduced by CCC, the higher rate reducing lodging more than the lower. Oat yields and 1000 kernel weights were not affected by treatment under either fertility regime; but the protein content of Rodney was depressed whereas that of Harmon was not. When no lodging occurred, CCC at 6.0 kg/ha increased triticale yields only on plots that received no nitrogen. Protein contents and 1000 kernel weights of triticale were unchanged in all treatments.

Lead Levels

According to environmental lead exposure data and dietary survey data of lead and zinc smelting area,blood lead levels of children (2~7years old) in study area were predicted with IEUBK model. The children's blood lead concentration predicted value was compared with the corresponding measured value,by comparing the differences, measured the prediction ability of model. The results showed that predicted value and measured value of 2~7 years old children's blood lead concentration in A village were higher than the other villages, they were 33.5μg/dL,30.8μg/dL, respectively; predicted value and measured value of 2~7 years old children's blood lead concentration in I village were the lowest among all villages,they were14.5μg/dL,13.1μg/dL, respectively.By paired T-test showed that the predicted value were higher than the measured value about 1.4~3.4μg/dL,model calculation results slightly overestimated the children's blood lead level.But in general, the predicted value and measured value had a good consistency,through the model prediction could better reflect the children's blood lead levels in the study area.
