Assessment of diffuse pollution associated with metals in urban sediments using the geoaccumulation index (Igeo)   总被引：1，自引：1，他引：0  

Leidy Luz García Martínez  Cristiano Poleto 《Journal of Soils and Sediments》2014,14(7):1251-1257

Purpose

This study investigated the behavior of cadmium (Cd), lead (Pb), nickel (Ni), and zinc (Zn) in urban sediments collected in commercial, residential, and industrial areas of the city of Porto Alegre, Brazil, and evaluated different degrees of pollution in this urban subdrainage basin through the use of the geoaccumulation index (I_geo).

Materials and methods

Concentrations of Cd, Ni, Pb, and Zn were analyzed using acid digestion (EPA method 3050) in fractions <63 μm in 20 composite samples of urban sediment collected using a portable vacuum in 20 different sampling points on roads from three areas with diverse use: commercial, industrial, and residential.

Results and discussion

The values of I_geo were commercial area (3.35, Zn; 3.76, Cd; 3.60, Ni; 2.63, Pb) > residential area (3.34, Zn; 3.36, Cd; 2.94, Ni; 1.46, Pb) > industrial area (2.74, Zn; 1.78, Cd; 3.01, Ni; 1.45, Pb), indicating that the sediment was “highly contaminated” in the case of Zn and Ni, while for Cd, it was “moderately to highly contaminated,” and for Pb, it was “moderately contaminated.” The pollution is associated with traffic flow in all areas.

Conclusions

Research should be increased to make urban systems more sustainable, reducing their pollution potential and minimizing the delivery of potentially polluting particles into freshwater bodies. The I_geo allows for the determination of a simple index of diffuse pollution state associated with urban sediments.  相似文献

Deaths in sheep exported by sea from Western Australia - analysis of ship Master''s reports     

RT NORRIS  RB RICHARDS 《Australian veterinary journal》1989,66(4):97-102

Mortality reports were studied for 181 shipments of live sheep from Western Australia to the Middle East and Singapore in 1985 and 1986. Samples of pelleted feed for 93 shipments were analysed for quality. Overall death rate in the 6.46 million sheep exported in the period of the study was 2.18%. In sheep bound for the Middle East, most of the deaths occurred during the voyage (overall rate 1.7%, range 0.4-4.4% per shipment), although substantial mortality was recorded during discharge (rate 0.4%, range 0.0-1.8%). There were few deaths during loading (rate 0.07%, range 0.0-0.8%). Deaths in sheep bound for Singapore were almost 10-fold lower than those sent to the Middle East. Several findings suggested that ship design and management may contribute to mortality. Death rates were invariably low on some ships and often high on others. Death rates were nearly always higher in enclosed decks than in open decks on 4 vessels, and point epidemics of mortality were observed in several shipments. Temperature and relative humidity measured on the ship's bridge were not closely related to daily death rate. Antibiotics estimated to cost $226,000 were used during 33 voyages in 1986 and were considered of dubious efficacy on shipboard mortality. Analysis of feed pellets used on ship showed that the quality of the diet was within the range set by draft national standards for pellets used in the live sheep export industry.  相似文献

Correlation of electrophoretic urine protein banding patterns with severity of renal damage in dogs with proteinuric chronic kidney disease          下载免费PDF全文

Background

Urine protein loss is common in dogs with chronic kidney disease (CKD). Currently available noninvasive means of evaluating CKD in dogs cannot accurately predict the severity of glomerular and tubulointerstitial damage. Electrophoretic analysis of urine proteins can indicate the compromised renal compartment (glomerular vs tubular), but extensive evaluation of protein banding pattern associations with histologic damage severity has not been performed in dogs.

Objectives

We aimed to evaluate electrophoretic banding patterns as indicators of the presence and severity of glomerular and tubulointerstitial damage in dogs with naturally occurring, predominantly proteinuric CKD.

Methods

We performed a retrospective study using urine and renal tissue from 207 dogs with CKD. Urine protein banding patterns were correlated with histologic severity of renal damage. Sensitivity and specificity of banding patterns for the detection of glomerular and tubulointerstitial damage were determined.

Results

Banding patterns were 97% sensitive and 100% specific for the detection of glomerular damage and 90% sensitive and 100% specific for the detection of tubulointerstitial damage. Correlations between composite banding patterns and the severity of renal damage were strong, while glomerular banding patterns correlated moderately with glomerular damage severity, and tubular gel scores correlated weakly to moderately with the severity of tubulointerstitial damage.

Conclusions and clinical importance

Urine protein banding patterns are useful for the detection of glomerular and tubulointerstitial damage in dogs with proteinuric CKD.  相似文献   

Antimicrobial delivery by intrasynovial catheterisation with systemic administration for equine synovial trauma and sepsis     

AA Stewart  LR Goodrich  CR Byron  RB Evans  MC Stewart 《Australian veterinary journal》2010,88(4):115-123

Objective To present the technique for intra-articular catheter placement and report the clinical outcomes of 38 cases of equine synovial trauma and/or infection treated with broad-spectrum antimicrobials administered via an intrasynovial catheter (ISC). Design Retrospective study. Procedure Medical records of 38 horses treated for synovial trauma and sepsis with frequent antimicrobial administration through an ISC from 1995 to 2008 were reviewed. Follow-up information was obtained via clinical re-evaluation or telephone contact with the owners. Results The majority of horses (84%) received amikacin and Timentin® four times daily. In addition, synovial lavage through the ISC was carried out in 27 horses (71%). Only radiological evidence of osteolysis had a significant negative impact on both lameness at the time of hospital discharge and the long-term outcome. In total, 92% of horses treated with frequent antimicrobial administration through an ISC had clinical resolution of infection. Catheter obstruction occurred in three cases, necessitating replacement or removal, and two synovial fistulae developed at sites of open drainage. The majority of horses treated had a favourable outcome, with 86% being at least pasture sound and 43% returned to riding. Conclusion Septic synovial structures treated with frequent antimicrobial administration through an ISC had a good prognosis for survival and 43% returned to riding, which is consistent with the results of other studies. The use of a simple ISC should be considered when broad-spectrum intrasynovial antimicrobial administration and lavage of a septic synovial structure are indicated.  相似文献   

Causes of death in sheep exported live by sea     

RB RICHARDS  RT NORRIS  RH DUNLOP  NC McQUADE 《Australian veterinary journal》1989,66(2):33-38

Post-mortem examinations were conducted on 950 dead and terminally ill sheep during assembly for export and during transport by sea from Fremantle, Western Australia to various Middle East ports. Causes of death were grouped into 5 major categories; inanition (deaths associated with reduced feed intake, including hypocalcaemia and hypomagnesaemia), salmonellosis (enteric and septicaemic), trauma, diseases associated with excessive feed intake (lactic acidosis and enterotoxaemia) and miscellaneous diseases (mostly of farm origin). During assembly the causes of death were salmonellosis 53.4%, miscellaneous diseases 23.8%, trauma 12.6%, inanition 10.2%, acidosis 3.9%, enterotoxaemia 3.4% and no diagnosis was made in 3.4%. During shipping the causes of death in defined populations of sheep in 5 voyages were; inanition 43.4%, salmonellosis 20.2%, trauma 10.6%, miscellaneous diseases 5.9%, enterotoxaemia 1.0% and no diagnosis was made in 19.0%. The range of mortality rates per 10,000 sheep at risk for the first 11 days at sea in 5 voyages were inanition 52.6 to 76.7, salmonellosis 7.8 to 109.8, trauma 2.1 to 17.1, miscellaneous diseases 5.9 to 17.1 and enterotoxaemia nil to 10.3.  相似文献
