The levels of radon, thoron and their progeny concentrations in Al-Nayriya, Al-Musbah Street, Nawab Al-dhubat and Al-mashtel, as well as Canal Street in southeast Baghdad were studied by using The Twin Cup Dosimeter. A total of 15 samples selected from 5 regions (3 samples from each region) in Baghdad city have been placed in the dosimeters for 100 day. The average radon and thoron concentrations were found to be 45.47 and 43.15 Bq/m3 respectively. Their average progeny concentrations were found to be 4.91 and 1.16 mWL.The dose received by persons living in the studied areas is less than the internationally permissible limits, which were determined by the ICRP of 3-10 mSv /y.

Chicken meat are being widely consumed as they contain high protein and a healthier unsaturated fat type. Chicken burger represent a consumer palatable chicken product. Both chicken and its products are liable to different types of contamination during their preparation and processing. Contamination by S. aureus and its enterotoxins poses a major public health hazard to chicken meat consumes. During this study 100 different samples of chicken fillet, deboned thigh, wing, mechanically deboned meat (MDM) and chicken burger (20 each) was collected from market and investigated for their S. aureus count and ability of the isolated strains to produce enterotoxins using conventional plating and isolation technique as well as using SET-RPLA toxin detection kit. Results revealed that mean values of S. aureus count in all samples exceeded the permissible limits and hence being unacceptable. MDM isolated exhibited staphylococcal enterotoxins (SEs) production of three different types SEA, SEC and SED. Meanwhile chicken burger S. aureus isolates produced only SEA and SEC enterotoxins. While isolated S. aureus from chicken fillet and deboned thigh didn’t exhibit any enterotoxin production activity. It’s recommended to follow the hygienic practices during different processing stages to avoid the risk of S. aureus and its enterotoxins.

Leachate Pollution Index

The improper treatment of landfill leachates is one of the major problems associated with waste landfilling and causes serious environmental pollution at waste landfill sites and their surroundings. To develop a suitable landfill leachate treatment system and to minimize the risk of environmental pollution, it is important to characterize seasonal and temporal variations of landfill leachates. This study investigated the leachate quality of the Nam Son waste landfill in Hanoi, Vietnam in 2017–2019 and characterized the potential risks of landfill leachate using a leachate pollution index (LPI). The results of this study showed that the seasonal and temporal variation of the overall LPI during the monitoring period was small and in the range of 20–25 (values 2.5 times higher than the maximum permissible limits of Vietnam National Technical Regulation on Industrial Wastewater). The LPI sub-indices attributed to organic and inorganic pollutants were major components of the LPI. Especially, the annually averaged values of LPI of inorganic pollutants were 7.7 times higher than the maximum permissible limits, suggesting that the treatment of inorganic pollutants, such as ammonium-nitrogen (NH4+–N) and total nitrogen (TN), is highly required at Nam Son landfill to prevent environmental pollution surrounding the landfill site.

An investigation was undertaken in 10 villages (28 samples) of Basavan-Bagewadi taluka and 11 villages (38 samples) of Muddebihal taluka of Bijapur district to assess fluoride and other physicochemical parameters. And also to assess the clinical symptoms like dental and skeletal fluorosis, joint pains and gastrointestinal diseases and to find out the severity of the disease. A check list developed with the help of available literature and in consolation with nutritionists was used to record clinical symptoms. A sample survey was made after examination for both sexes between the age of 8-50 years at Basavan-Bagewadi and Muddebihal taluka. Fluoride content varies from 0.40-6.40 mg/L and 1.10-7.10 mg/L. However 12 samples were within the range, while 16 samples were above the permissible limits at Basavan-Bagewadi Taluka where as in Muddebihal taluka all the values are above the permissible limits of WHO respectively. The results show that, out of the 2992 examined 824 (25.89%) people have dental and skeletal fluorosis, 274 (9.15%) people have joint pains, 167 (5.58%) have gastrointestinal discomfort and excessive thirst at different stages in Basavan-Bagewadi taluka. Among 2696 examined, 812(29.49%) people had dental and skeletal fluorosis, 432 (16.18%) people had joint pains, 415 (15.54%) people had gastrointestinal discomfort and excessive thirst at Muddebihal taluka of Bijapur district.

Development Analysis

EDQ introduces a new format to the Forum section in this issue. Periodically an article is submitted to us that raises important policy or methodological issues that have generated sharp responses from external reviewers. We believe that the debate that has taken place between the authors and reviewers is of such importance that we have then solicited people to comment on the article. Controversy on Maxwell Street raises the issue of the marriage of anthropologic and economic techniques in economic development analysis. We hope that you find this debate as stimulating as we did. Controversy on Maxwell Street began when Morales, Balkin, and Persky submitted their article, “The Value of Benefits of a Public Street Market: The Case of Maxwell Street.” We then requested that Rhoda H. Halperin and Wim Wiewel respond. Following their responses is a rejoinder by the authors. Chicago's Maxwell Street Market was among the oldest open-air public markets in the United States. The market was closed in August 1994 and a smaller alternative market was opened on Canal Street. This article estimates monetary losses resulting from the closure of the market. First, the authors briefly discuss the markets history, followed by a review of the literature on the informal economy. The problem of quantifying the value of street vending is addressed by combining ethnographic and economic analytical methods. Ethnography is introduced in the article's third section. The authors demonstrate the usefulness of merging ethnographic and economic analysis by estimating monetary losses to vendors and consumers as a result of changes in the market's governance and location.

Development Of Resistance

The development of resistance in bacteria against commonly used antibiotics/drugs is of considerable medical significance. Aim of this study was to determine the microbial load of un-pasteurized packed fruit juices sold in Lahore city and to determine antibacterial activity of five different honey samples against isolated bacteria. Unpasteurized fruit juice samples (n=60) were collected from street vendors. All the samples were subjected to Total viable count (TVC), Staphylococcal count (SC) and Coliform count (CC). One hundred and ten strains of bacteria were isolated from various fruit juices and identified on the basis of cultural characters, morphology and biochemical characters. Mean TVCs, SCs and CCs of juices (6.80±1.91, 5.45±1.06 and 3.25±1.25 log10 CFU/ml respectively) were non-significant with standard permissible limits (p<0.05). Among all the fruit juices, 66.66% of samples had TVC more than 4 log10 CFU/ml, 51.66% of samples had SC more than 3 log10 CFU/ml and 46.66% of samples had CC more than 2 log10 CFU/ml. Among the bacillus isolates purified, were Bacillus alvei, Bacillus subtilis, Bacillus polymyxa, Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumonia, Escherichia coli and Enterobecter. All five different types of honey samples used in this study showed antibacterial activity against B. alvei, B. polymyxa, B. subtilis and S. aureus and no activity against P. aeruginosa, K. pneumonia, Enterobecter and E. coli. It is concluded that microbial load in unpasteurized fruit juices is significantly higher than standard permissible limits which insinuates its possible role in spoilage and food borne illnesses. Periodic monitoring of packed fruit juices should be carried out to make them safe for consumption. Honey can be used as an alternative for treatment of various infections, especially those caused by antibiotic resistant bacteria.
