Ceramic crockeries decorated with glaze matter containing various essential (Zinc, Iron, and Barium, etc.) and non-essential heavy metals (lead and cadmium) can adulterate the foodstuff and/or can release deadly metals into the food substance. Chines, Indian, and Spanish ceramic crockeries were randomly selected from the products available in the local Qatari market and analyzed to determine the level of leachable essential and non-essential heavy metals. Leaching studies were performed according to the ASTM 738-94 standard test methods for specific metals leaching into 4% acetic acid solutions over 24 hours exposure time. ASTM 738-94 is a precise and standard method and particularly designed for the determination of some heavy metals extracted by acetic acid from the glazed ceramic surface. Results show that all the ceramic crockeries contain both leachable essential and non-essential heavy metals. However, the concentration of these heavy metals is not potentially high to cause any adverse effect on human health.","PeriodicalId":14865,"journal":{"name":"Journal of analytical and bioanalytical techniques","volume":"37 1 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2018-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77963166","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}

The major pests were observed that hamper the growth of agricultural crops are insects, fungi, and weeds. Pesticides are the chemicals used against pests. Many precautions are taken to avoid these pests. But, there should be a strategy for use of the chemicals for the sake of food safety. Which means many different products should be under routine control for pesticides residue in a specific zone [1]. Governments in many countries have established new institutions, standards, and methods for regulating food safety and have increased investments in hazard control. United Nations Conference on Environment and Development recognized food as major vehicles for trade commodity and environmental contamination. Sustainable agricultural practices that are promoted for mitigating climate change have the potential to also improve pest management [2]. The over use of synthetic chemicals to control pests and diseases has become widespread in the 20th century especially after the Second World War. An increase in food production has been observed with the increasing World population. However, the quality of food came as a big questions over time. It has been observed that farmers aim to get more and more yield lead to apply more synthetic pesticides. The pesticides were identified as persistent organic pollutants (POPs) by the Stockholm Convention in 2001. Chemical substances and their persistance in the environment, bio-accumulation through the food web, pose a risk of causing adverse effects to human health and the environment. Pesticides are grouped in many classes among them Organochlorine Pesticides (OCPs) played an important role at the beginning.","PeriodicalId":14865,"journal":{"name":"Journal of analytical and bioanalytical techniques","volume":"29 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86010095","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}

Separation and analysis of drospirenone, ethinyl estradiol and levomefolate was achieved on Waters C18 (5 μm, 250 mm × 4.6 mm) column using 0.1% H3PO4, methanol and acetonitrile in the ratio of 60:20:20 (v/v/v) as mobile phase at 27°C. The flow rate was 1.0 mL/min. The effluents were monitored with detector set at 245 nm. The method validation was done with regard to the guidelines by the International Conference on Harmonization and US Food and Drug Administration. All the validation characteristics are within the acceptance criteria. The studied drugs were subjected to acid, alkali and neutral hydrolysis, hydrogen peroxide oxidation, thermal degradation, and photo (sunlight) degradation. The peaks of degradation products were well resolved from the peaks of three analytes (drospirenone, ethinyl estradiol and levomefolate). Hence, the developed and validated liquid chromatographic method is able to quantify the drospirenone, ethinyl estradiol and levomefolate in the presence of degradation products.","PeriodicalId":14865,"journal":{"name":"Journal of analytical and bioanalytical techniques","volume":"20 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79333449","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}
