Opis:
The present work measures the adsorption capacity of sugarcane bagasse to remove excess lead from groundwater. Batch adsorption experiments were carried out to evaluate the adsorption equilibrium, and the effects of four parameters (pH, adsorbent dosage, equilibrium time and particle size) on the adsorption of lead were investigated. Characterization of the adsorbent was carried out through SEM and FTIR instruments. Results confirm that the adsorption of lead takes place successfully on the surface of the adsorbent. The maximum efficiency of adsorption is up to 50% achieved in 5g adsorbent dosage, at an optimum pH 5, with a contact time of 120 minutes and 53 μm adsorbent size at 38.

Opis:
Cataract is one of the main causes of vision loss. So far, it has been found that one of the causes of cataract formation is the accumulation of heavy metals in ocular tissues and environmental pollution. Research material consisted of blood from healthy volunteers (n = 81; Mogilno Lakeland) and those suffering from cataract (n = 90) from Ophthalmology Clinic, Bydgoszcz (2013, 2016). Samples were prepared in order to obtain plasma, which was used to analyze Fe, Cu, Zn, Mn, Pb, Cd, and Hg concentration (ICP-MS). The purpose of this study is to show the interaction of cataract with cadmium and lead during initial pro-antioxidative reactions and to study element-element interactions. To this end, we analyzed physiological mechanisms that aim to stop the destructive effects of toxic metals. We have shown that the action of zinc, copper and manganese is antioxidant. Concentration of these elements is higher (α = 0. 05, p < 0.05) in the cataract group than in the control. We found interactions Fe-Cu-Zn-Mn-Pb-Cd-Hg. Cd and Pb show a negative effect on the eye tissue and generate pathophysiological changes leading to lens opacity and influence the destabilization of pro-antioxidant reactions. Correlations of elements in the control (Cd-Zn: R = 0.240; Cd-Cu: R = 0.316) and in the sick group (Cd-Cu; R = 0.329) were significant. On the basis of our research we found that there are numerous relationships between the concentrations of chemical elements in the patients with cataracts and the controls. Significant role of antagonisms with cadmium and lead has been demonstrated; these elements contribute to the gradual development of cataract. A correlation between elements exhibiting pro-antioxidant activity in the interactions with cadmium and lead (p=0.000) can be a source of cataract changes. The differences in Cd and Pb concentration and their interactions with elements between the control and sick groups can be considered as a factor for the development of cataract.

Opis:
Currently, much attention is paid to the search for the etiology of many eye diseases. It has been shown that environmental pollution with heavy metals (cadmium, lead, mercury) is of significant importance. One of these diseases is cataract, i.e. clouding of the lens of the eye. It turns out that heavy metals are deposited in the tissues of the eyes, damaging them and accelerating the disease. This work is aimed at presenting the problem of the influence of heavy metals on cataracts. The study compares the concentration of heavy metals between the control group (81 healthy volunteers) and the group of cataract patients (72 sick). Plasma was used in the research and the ICP-MS method was used.

The study was conducted in July - August 2018 with the aim of analyzing the concentration of lead heavy metals (Pb) in water, sediment and macrozoobenthos in the Karangsong waters area, Indramayu Regency. The research method used is a survey method with purposive sampling technique that is the determination of location based on the existence of certain objectives and in accordance with various considerations, then observed the content of lead metal (Pb) in the Central Laboratory of Padjadjaran University. The research was conducted in situ and exsitu. Parameters of insitu research include temperature, pH and DO carried out in Karangsong waters, Indramayu Regency. Exsitu research parameters include testing of lead metal (Pb) on water, sediment and macrozoobenthos conducted at the Central Laboratory of Padjadjaran University. The results showed that the Pb concentration in the Karangsong waters had exceeded the threshold, which ranged between 1,05 – 1,33 mg/l, while the Pb concentration in sediment was higher than the Pb concentration in water. Lead metal in sediment has not exceeded the threshold. The ability of macrozoobenthos to accumulate lead metal in water and sediment (Bioconcentration Factor / BCF) is included in the low accumulative category because BCF is less than 100.

Opis:
Worldwide, there have been longstanding issues of heavy metal pollution of both ground and surface waters from industrial effluents. In this research, Daniella oliveri leaves were investigated as a precursor for the development of low-cost adsorbent for removing Pb(II) from aqueous media. The adsorbents (biosorbent and ash) were characterised using Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDS) and Branueur-Emmet-Teller analysis (BET). The biosorbent (DO-B) and ash (DO-A) from Daniella oliveri leaves had a specific surface area of 574.5 m2/g and 723.0 m2/g respectively. Both adsorbents were mesoporous with pore diameter >2 nm. The ash was a better adsorbent for Pb(II) than the biosorbent powder, however, both adsorbents have over 99% removal of Pb(II) at optimal conditions. Best-fit isotherm for DO-B was Freundlich isotherm while no best fit for DO-A was observed. The adsorption for both adsorbents was best fit pseudo-second order kinetic model. Adsorbents from Daniella oliveri leaves could be used as an adsorbent for the removal of Pb(II) from aqueous media and can play an important role in mitigating the potential impact of the release of industrial effluent into the environment.

Aims of the research are to determine the type of activated carbon with high absorption rate in absorbing heavy metals of lead in green shells. This research used experimental method with complete randomized design then analyzed used analysis of variance and duncan test to see the decrease of lead in green shells by using different charcoal filters. The results showed that the highest decrease in green shell was by using coconut shell activated filter are 0,28 with a decrease percentage of 36,51%. The best lead decrease in water maintenance coconut shell activated filter treatment are 0,33 ppm. The coconut shell activated charcoal has a low ash content compared to other types and large pore charcoal size. Factors that supporting the metal absorption by charcoal include ash content on charcoal, charcoal pores, carbon concentration and pH concentration. Water quality measurements were measured in the morning and evening as supporting parameters in the study. Water quality measurements are in a range that can still be tolerated by green shells. Based on these results it can be concluded that the use of coconut shell activated charcoal is the best type of charcoal in lowering lead in green shells.

Opis:
Semivariogram is a half variance diagram of the difference between observations at the location s_i with another location that is as far as h units of distance. Semivariogram is used to describe the correlation of observation sorted by location. This research discusses the theoretical Semivariogram for the Spherical, Gaussian, and Exponential Semivariogram models through the Linear Programming approach. Next, the Semivariogram parameter estimation is studied with the assumption that there are data uncertainties, called the Uncertain Semivariogram. The method used to overcome the uncertainty data is Robust Optimization. The Uncertain Semivariogram using Robust Optimization are solved using the box and ellipsoidal uncertainty set approach. The calculation of the application of the model was carried out using the R software. For the case study, the application of the model used secondary data of Lead pollutant data in the Meuse River floodplains on the borders of France and the Netherlands at 164 locations. Based on the calculation results, the Exponential theoretical Semivariogram model is obtained as the best Semivariogram model, because it has a minimum SSE. Furthermore, the application of the Uncertain Semivariogram model using Robust Optimization on the Semivariogram Exponential model of Lead pollutant data is carried out using the box and ellipsoidal uncertainty set approach which is to obtain computationally tractable results.

Opis:
During the growth of cadmium iodide crystals from solution, it has been observed that sometimes the crystal suddenly rotates. Probably, the convection currents are providing the force for the rotation. Mathematically, this force can be estimated and it must be greater than the van-der Walls force acting between adjacent sandwiches of cadmium iodide and can give rise to polytypic phase transformations. Further, studies of vacancies and the density measurements of various polytypes can help in understanding the phenomenon of polytypism better.

Opis:
The study area is characterized by ubiquitous ore deposits within the underlying Asu River Group of the southern Benue Trough of Nigeria. The extensive mineralization resulted in widespread artisan and unlawful mining activities, necessitating the need for the assessment of the effects on soils in the area. Careful evaluation of the soils was undertaken to give account of heavy metals concentrations and distribution, and pollution level in soils across the lead – zinc mines. The soil samples were digested and chemically analysed using Atomic Absorption Spectrophotometer (AAS). Results showed concentrations of heavy metals of the soil samples in the order trend Zn>Pb>Mn>Cd>Cu>Fe> Ni>Co>Cr and Pb>Zn>Mn>Fe>Cu>Cd>Ni>Cr>Co in both Oshiri and Ishiagu areas. Cd showed high contamination in the soils with higher amount of contamination occurring in Oshiri. Findings also revealed Co, Fe Cu, Mn, Zn, Pb and Ni whose Igeo’s values indicated uncontaminated to moderate contamination have an insignificant contribution to the pollution in the study area while Cd showed highest Igeo with moderate contamination. Co, Cr, Ni, Pb and Zn show deficiency to minimal enrichment while Cd recorded very high enrichment 23.95 – 37.48 and 25.66 – 34.21 mk/kg in the Oshiri and Ishiagu areas respectively. Cd showed high index of contamination ranging from 7.21 – 13.89, while other metals showed no index of contamination in the area. Pollution load index indicates that only few sites in Oshiri area require urgent rectification measures. The food chain in the area is not safe due to possible biomagnifications; hence arable soil around the mines is not suitable for production of food crops.

Opis:
Molluscs represent a simple and significant model system to test how specific metals can simultaneously affect development and putative mechanisms of defense and/or cell death. Lamellidens marginalis (Bivalvia: Eulamellibranchiata) are the molluscs of Indian freshwater ecosystem and important biological resources. Lead (Pb) is widespread heavy metal that is released into the environment from different sources. Their accumulation in the soils can become dangerous to all kinds of organisms, including plants, animals and human life, causing many adverse effects. Lamellidens are used as reliable markers and bioindicators highly sensitive to environmental changes. The aim of the present work was to determine the toxic effect of lead on the cytomorphology of hemocytes of Lamellidens marginalis and to evaluate its potential as a bio monitor for detecting a heavy-metal polluted environment. Treated cells showed apoptosis and paraptosis (vacuolation) like features. Morphological analyses suggested an irretrievable destruction of normal morphology of hemocyte. However further studies are needed to investigate this topic, particularly in relation to the pollutants reported in this paper.

Included in the atmosphere, dust and heavy metals fall to the ground parts of plants and enters the soil. Shall be collected by the roots of plants or animals grazing on the roads and thus incorporated into the food chain. These elements are not biodegradable. They are indestructible and indelible. Once released into the environment continuously circulate therein, changing, at most its shape. Heavy metals are ubiquitous and can be detected in every organic material and in every living organism. They are a particular threat to humans.

Opis:
The research objectives are: 1) to analyze several parameters of the aquatic environment that affect the lead accumulation in shellfish body (Anadara granosa (Linnaeus, 1758)) at eastern coastal waters of Muara Gembong sub-district by using multiple regression analysis, 2) to reduce the variables through principal component analysis to reduce the research cost for monitoring of lead pollution in the next time, and 3) to analyze the location which has similar characteristics of lead accumulation by using hierarchical cluster analysis. Based on the multiple regression analysis, the lead concentration in water, lead concentration in sediment, and sulfur concentration in sediment has a very significant correlation (P < 0.01) to the lead accumulation in shellfish body. In contrast, COD of waters has a significant correlation (P < 0.05), which correlation coefficient (R) is 0.97. Through the principal component analysis, the lead concentration in sediment, COD of waters, and sulfur concentration in sediment gives the most variance contribution to the total data variance. Therefore, those variables are sufficiently used to monitor lead pollution on shellfish at the Muara Gembong sub-district's coastal waters. Cluster analysis shows that the location is agglomerated to be 3 clusters, which coastal water of Southern Bahagia Beach and Western Mekar Beach has highly similar lead accumulation characteristics.

Opis:
Heavy metal pollution is an ever increasing problem of our lakes. These toxic heavy metals entering in aquatic environment are adsorbed onto particulate matter, although they can form free metal ions and soluble complexes that are available for uptake by biological organisms. The increase in residue levels of heavy metal content in water, sediments and biota has resulted in decreased productivity and increase in exposure of humans to harmful substances. Many of these metals tend to remain in the ecosystem and eventually move from one compartment to the other within the food chain. Food chain contamination by heavy metals has become a burning issue in recent years because of their potential accumulation in biosystems through contaminated water, soil, sediment and air. The Dąbie Lake is an integral part of the River Odra estuary. It is a shallow (2.5 m mean depth) water body with two distinct basins: the large (Dąbie Wielkie) and the small (Dąbie Małe). The aim of the studies, carried out in the years 2008 - 2012, was to determine the content of Cadmium (Cd), Chromium (Cr), Copper (Cu), Mercury (Hg), Nickel (Ni), Lead (Pb) and Zinc (Zn) in the waters of Dąbie Lake, being the internal part of the tertiary Odra estuary. The range of observed concentrations (ppm) for the analysed metals was between: maximum concentration of Cd was 0.97 ppm and the minimum was 0.42 ppm; maximum concentration of Cr was 0.28 ppm and the minimum was 0.12 ppm; minimum concentration of Cu was 0.04 ppm and maximum of 0.08 ppm; maximum concentration of Hg was 0.07 ppm and the minimum was 0.03 ppm; minimum concentration of Ni was 2.29 ppm and maximum of 2.97 ppm; maximum concentration of Pb was 0.09 ppm and the minimum was 0.04 ppm; minimum concentration of Zn was 2.85 ppm and maximum 3.94 ppm.
