The results disclosed that, healthcare facilities whether private and governmental hospitals still suffer from inappropriate biomedical wastes management which have not received sufficient concern according to 60% of participants who pointed out that hazardous and medical wastes are still handled and disposed together with domestic wastes and segregation was applied only for sharp waste which is collected in special sharp boxes at the beginning after usage. Furthermore, around 47% of respondents don't know where medical storage place is, and don't know if there is mark to show place of storage. Besides, 42% of respondents don't know if it's there mean for transferring medical waste, and 43% don't know its type or if it's available always. In the surveyed hospitals, there is deficiency in implementing training courses about healthcare waste management as 23% only of all study subjects had been provided with training on how to deal with medical waste. Therefore, the Ministry of Health and healthcare institutions should give more consideration towards policies for the proper management and disposal of health care wastes in order to develop medical waste management practices in Palestine.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"17 1","pages":"164-173"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90198208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heavy metals restrain biodegradation of chlorinated organics by interacting with enzymes directly concerned in biodegradation or those involved in common metabolism. Prophecy of heavy metal toxicity effects on organic pollutant biodegradation in co-contaminated soil is tricky since heavy metals may be present in a variety of chemical and physical forms. Even if much remains to be studied, phytoremediation will clearly play some role in the stabilization and remediation of many contaminated sites.

Due to their economic importance, fruit flies are severe pests of Mango Mangifera indica L. fruit, and their monitoring and infestation estimation are essential in order to formulate integrated pest management program. For practical field implementation, two variables such as flies per trap per weak were monitored by installation of Steiner traps hung on tree baited with Methyl eugenol attractant and percent fruit infestation through fruit host samplings. Surveillance for flies per trap was done each week by counting trap catches, recording and removing any flies that have been collected in traps and identifying the species. The percentage of fly infestation for mango fruit was examined by randomly analyzing a total of 100 fruits and observing number of fruits showing fruit fly oviposition or injury marks. The results showed that tephritid fruit fly Bactrocera zonata (Saunders) was the predominant species (more frequent and constant) at experimental site. Surveillance of fruit fly populations in mango orchard revealed that peak population of B. zonata (40-30 per trap per week) and fruit infestation (9.05-7.45%) were recorded in June, July and August. The availability of host fruit and its productivity were critical factors affecting population fluctuations of the B. zonata fly. All of this information gives fruit fly activity in an area, an estimate of the population, species composition, sex, growth stage and determining whether the number of pests are increasing or decreasing to decide implementation of pest control operation. Mango (Mangifera indica L.), is one of the most versatile and delicious tropical fruits, and having an outstanding flavor with a range of varieties as a member of the family Anacardiaceae. Mango has a good nutritional value and there is great variation in the form, size, color and quality of the fruits. Mango is an excellent source of vitamin A and C, as well as a good source of potassium, beta-carotene and fiber. Normally, it is produced for human consumption as raw or ripe mango products. During the processing of ripe mango, its peel and seed are generated as waste, which is approximately 40-50% of the total fruit weight. Mango peel is a good source of dietary fiber and its chemical composition may be comparable to that of citrus fiber. The peel has a high value of antioxidant activity and glucose retardation index, while its aroma and flavor are pleasant (Larrauri et al., 1999).

The study was conducted to investigate the role of cattle grazing in soil degradation resulting from compaction using infiltration parameters at the Beef and Dairy Cattle Research Station of the Department of Animal Science of the Faculty of Agriculture, KNUST. Two fields, ungrazed and grazed (with a stocking rate of 120 cattle for three weeks) were used for the study. Physical properties such as soil texture, moisture content, bulk density, total porosity and aeration were determined. Field infiltration studies from which sorptivity (S) and steady state infiltrability (Ko) were determined were conducted with a double ring infiltrometer for one hour to determine the cumulative infiltration amount (I). The time-to-incipient ponding or runoff initiation time (tp) was calculated from the S and Ko values. Mean values of I were 1490 mm and 500 mm; S 2.72 mm/s 1/2 and 1.030 mm/s 1/2 ; Ko, 0.060 mm/s and 0.0080 mm/s for the ungrazed and grazed fields, respectively. The tp at a rainfall rate of 5 mm/h was recorded as 79.00 s on the grazed field and 419.00 s for the ungrazed field. It was observed that rainfall rates in excess of 10 mm/h would cause instantaneous ponding and/or runoff on both fields. Grazing by cattle was, thus, established to be deleterious to soil structure and infiltration due to soil compaction. Overall, infiltration parameters were found to be very useful tools for the evaluation of soil degradation due to compaction.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"45 1","pages":"139-149"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84893852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this research was undertaken to investigate the biodegradability of semi-aerobic sanitary landfill and the ratio of the biological oxygen demand (BOD) to chemical oxygen demand (COD) BOD5/COD, COD fraction on leachate from Pulau Burung landfill Site (PBLS). These parameters are important as they may provide appropriate and suitable treatment for this kind of leachate. In this research, leachate from two different ponds were studied i.e., the raw leachate from leachate collection pond and the leachate effluents of the treatment plant'. Five different measurement points were tested for each pond to understand the characterization for leachate. The soluble and particulate organic compound was separated by filtration using a 0.45μm pore size membrane filter. The results indicated that leachate in PBLS has low BOD5/COD ratio. The total COD (TCOD) ranged from 2040mg/L to 3160mg/L. The Biodegradable COD (BCOD), unbiodegradable COD (UBOD), soluble biodegradable (RBCOD), particlulate biodegradable (SBCOD), particulate inert (UPCOD), and soluble inert (USCOD) ranged from 53%-67%, 33%-47%, 38%-46%, 9%-25%, 12%-26%, and 18%-25%.
