Differences (p < 0.05) were noticed in the crude protein (17.85-31.17%), total lipids (49.81-66.96%), carbohydrate (1.46- 14.14%), moisture (2.50-4.50%) and ash (1.50-3.60%) contents of the nuts. The palmitic acid and stearic acid were the main saturated fatty acids (SFA), oleic acid was the predominant monounsaturated fatty acids (MUFA), while the linoleic and linolenic acid were the major polyunsaturated fatty acids (PUFA). The percentage of linoleic acid exceeded that of linolenic acid in all analyzed nut samples. A major finding of LC-PUFA (Long Chain PUFA) among walnut was found higher (72.14 g/100g), due to higher linoleic and linolenic acid (57.26 and 14.88 g/100g). In addition the calculated essential PUFA/SFA ratio was ranged as 3.10-11.49. However ratio of n-6/n-3 FA ranged 3.83-11.05, lower n-6/n-3 for walnut is beneficial for nutrition purpose by providing more n-3 essential FAs in comparison of other analyzed nuts. The results showed that all selected nuts have good nutritional quality and could be used in fighting malnutrition and can serve as valuable source of oil for industrial purposes.","PeriodicalId":19846,"journal":{"name":"Pakistan Journal of Analytical & Environmental Chemistry","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2019-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48351197","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}

This study was based on the analysis of heavy metals in eighteen selected varieties of rice (Oryza sativa L.) that circulates in local market of Karachi, Pakistan. Few heavy metals namely, Cadmium (Cd), Chromium (Cr), Cobalt (Co), Copper (Cu), Lead (Pb), Manganese (Mn), Nickel (Ni), and Zinc (Zn) were analyzed using Atomic Absorption Spectroscopy (AAS). Rice samples were digested using nitric acid (conc.). Average concentrations of Cd, Co, Cr, Pb, Ni were 7.3, 10.6, 107, 117, 139 μg kg-1 of rice respectively, whereas, the respective concentrations of Cu, Mn, and Zn were found to be 4.7, 9.7, and 14.6 mg kg-1 of rice.

The PCDDs were extracted using 1:1 acetone: n -hexane mixture followed by cleaning with acidic aluminium oxide in polypropylene mini columns and eluted with dichloromethane. In quantitative determinations, the limit of detection for congener 1 of PCDDs was 0.4 ng mL -1 while for other congeners (2–4) it was found to be 1.0 ng mL -1 . The congener 1 was checked at spiking levels of 0.02, 0.05 and 0.1 ng g -1 , and its recovery was 85.96–120.74% and 95.32–116.88% from wheat and rice, respectively. Wheat and rice were also spiked by congers 2–4 at spiking levels of 0.05, 0.1 and 0.5 ng g -1 ; the recovery ranges from wheat were 87.70–115.54%, 85.64–117.88% and 88.40–119.32% for congener 2, 3 and 4, respectively, while from rice the recovery was 77.67–115.68%, 83.18–119.68% and 79.76–131.15% for congener 2, 3 and 4, respectively. The limit of quantification was determined as 0.1 ng g -1 for congener 1 and 0.5 ng g -1 for other three PCDDs (2–4). The intra-day and inter-day RSDs of peak areas ( n = 3) for four congeners (2 ng mL -1 ) were ranged at 2.5–8.1% and 3.1–10.6%, respectively.

Human vital activities are also responsible for the extra nitrogen released into the atmosphere. So, both human and environmental healths are negatively affected by the increasing nitrate and nitrate amounts in water and soil. For this reason, it is aimed to ensure regular control of nitrates and nitrites at certain levels in order to protect the universe and all living things. Their precise and selective determination by various methods is very important. Their determinations can usually be made by using electrochemical, spectrophotometric, chromatographic and titrimetric methods. Nowadays instead of these techniques, sensors are preferred in determining nitrate and nitrite due to their easy, fast, selective and sensitive application properties. Furthermore, polymeric materials have shown great promise for different sensing applications such as gas, humidity, explosive and water pollutants. Sensors, which are developed by polymerization, have very high quality for the determination of nitrite. The highly sensitive results of optical and electrochemical sensors attract the attention of researchers. In this review, different detection methods for nitrite ions and various studies on the preparation of polymeric sensors that can selectively capture the nitrite ions in complex matrices are examined.","PeriodicalId":19846,"journal":{"name":"Pakistan Journal of Analytical & Environmental Chemistry","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2018-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48279271","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}
